|
Project length: | 5 years |
ATP funds: | $13,783K |
Cost-shared funds (est.) | $14,674K |
Total project funds (est.) | $28,457K |
The project was completed in April 1996. Actual ATP costs (pre-audited) amounted to $12.866 million over the five-year (statutory limit) funding period. Actual industry costs amounted to $13.693 million. During the project the U.S. Department of Energy added an additional $5.2 million. Thus, total project costs were $31.759 million. (5)
A. Early History of the Industry (6)
Dr. Paul Eisler, an Austrian scientist, is given credit for developing the first printed wiring board. After World War II, he was working in England on a concept to replace radio tube wiring with something less bulky. What he developed is similar in concept to a single-sided printed wiring board.
A printed wiring board (PWB) or printed circuit board (PCB) is a device that provides electrical interconnections and a surface for mounting electrical components. While the term PWB is more technically correct because the board is not a circuit, the term PCB is more frequently used in the popular literature. (7)
Based on Eisler's early work, single-sided boards were commercialized during the 1950s and 1960s, primarily in the United States. As the term suggests, a single-sided board has a conductive pattern on only one side. During the 1960s and 1970s, the technology was developed for plating copper on the walls of drilled holes in circuit boards. This advancement allowed manufacturers to produce double-sided boards with top and bottom circuitry interconnections through the holes. From the mid-1970s through the 1980s there was tremendous growth in the industry. In the same period, PWBs became more complex and dense, and multilayered boards were developed and commercialized. Today, about 66 percent of the domestic market is multilayered boards. (8)
B. Trends in the Competitiveness of the PWB Industry
As shown in Table 1, the United States dominated the world PWB market in the early 1980s. However, Japan steadily gained market share from the United States. By 1985, the U.S. share of the world market was, for the first time, less than that of the rest of the world excluding Japan; and by 1987 Japan's world market share surpassed that of the United States and continued to grow until 1990. By 1994, the U.S. share of the world market was approximately equal to that of Japan, but considerably below the share of the rest of the world, which was nearly as large as the two combined. While there is no single event that explains the decline in U.S. market share, one very important factor, at least according to a member of the PWB Project team, has been "budget cut backs for R&D by OEMs because owners demanded higher short-term profits," which led to deterioration of the industry's technology base. (9)
In 1991, the Council on Competitiveness issued a report on American technological leadership. (10) Motivated by evidence that technology has been the driving force for economic growth throughout American history, the report documented that as a result of intense international competition, America's technological leadership had eroded. In the report, U.S. technologies were characterized in one of four ways:
Competitive: meaning that U.S. industry is leading, but this position is not likely to be sustained over the next five years.
Weak: meaning that U.S. industry is behind or likely to fall behind over the next five years.
Losing Badly or Lost: meaning that U.S. industry is no longer a factor or is unlikely to have a presence in the world market over the next five years.
The 1991 Council on Competitiveness report characterized the U.S. PWB industry as "Losing Badly or Lost." However, in 1994, the Council updated its report and upgraded its assessment of the domestic industry to "Weak" due in large part to renewed R&D efforts by the industry. (11)

C. Current State of the PWB Industry
Table 2 shows the value of U.S. PWB production from 1980 through 1994. While losing ground in relative terms in the world market, the PWB industry grew in absolute terms over these 15 years. In 1994, production in the domestic market was $6.43 billion, nearly 2.5 times the 1980 level, without adjusting for inflation; in real dollars, that equates to 1.5 times the 1980 level.
There are two types of PWBs that account for the value of U.S. production shown in Table 2: rigid and flexible. Rigid PWBs are reinforced. For most panels, this reinforcement is woven glass. Rigid PWBs can be as thin as 2 millimeters (mils) or as thick as 500 mils. Generally, rigid boards are used in subassemblies that contain heavy components. Flexible PWBs do not have any woven glass reinforcement. This allows them to be flexible. These boards are normally made from thin film materials around 1 to 2 mils thick, typically from polyimide. As shown in Table 3, rigid boards account for the lion's share of the U.S. PWB market. In 1994, nearly 93 percent of the value of U.S. PWB production was attributable to rigid boards. Of that, approximately 66 percent was multilayer boards. (12)
As shown in Table 4, Japan dominated the flexible PWB world market in 1994; but North America, the United States in particular, about equaled Japan in the rigid PWB market.
There are eight distinct market segments for PWBs: (13)
Business/Retail: copy machines, word processors, cash registers, POS terminals, teaching
machines, business calculators, gas pumps, and taxi meters.
Communications: mobile radio, touch tone, portable communication, pagers, data transmissions, microwave relay, telecommunications and telephone switching equipment, and navigation instruments.
Consumer Electronics: watches, clocks, portable calculators, musical instruments, electronic games, large appliances, microwave ovens, pinball/arcade games, TV/home entertainment, video records, smoke, and intrusion detection systems.
Computer: mainframe computers, mini-computers, broad level processors, add-on memories, input devices, output devices, terminals, and printers.
Government and Military/Aerospace: radar, guidance and control systems, communication and navigation, electronic welfare, ground support instrumentation, sonar ordinance, missiles, and satellite related systems.
Industrial Electronics: machine and process control, production test measurement material handling, machining equipment, pollution, energy and safety equipment, numerical control power controllers, sensors, and weighing equipment.
Instrumentation: test and measurement equipment, medical instruments, and medical testers, analytical nuclear, lasers, scientific instruments, and implant devices.
As shown in Table 5, the computer sector absorbs the greatest proportion of U.S.-produced rigid and flexible PWBs. Comparing rigid and flexible board usage, the communications sector uses a higher proportion of rigid boards and a lower proportion of flexible boards, while the military uses a higher proportion of flexible boards relative to its use of rigid boards.
PWB producers are divided into two general groups: manufacturers that produce PWBs for their own end-product use and manufacturers that produce boards for sale to others. Those in the first group are referred to as original equipment manufacturers (OEMs) or captives, and those in the second group are referred to as independents or merchants. As shown in Table 6, independents accounted for an increasing share of all PWBs in the United States. (14) Their share of the total domestic market for rigid and flexible PWBs increased from 40 percent in 1979 to 83 percent in 1994. For rigid PWBs, independents accounted for 93 percent of the market in 1994. (15)
Table 7 shows PWB sales for 1990 and 1995 of the ten major OEMs in 1990. IBM's sales decreased during this period, but it sold its military division during the period. AT&T's sales increased, but in 1996 the PWB producing division of AT&T became Lucent Technologies. Lucent Technologies is now an independent producer. Digital's PWB segment became independent Amp-Akso in 1995, so 1995 sales for Digital are noted as na, or not applicable. Amp-Akso, as an independent producer, had sales in 1995 of $105 million. Hewlett-Packard and Unisys were no longer in the industry in 1995 and hence their 1995 sales are noted as $0. During this period, the major OEMs experienced the continuing market effects associated with their strategic decision to cut back or eliminate R&D in PWBs.
In comparison to the information in Table 7 on OEMs, Table 8 shows that the major independents' sales have generally increased. As a whole, their sales increased at a double-digit annual rate of growth over the time period 1990 to 1995. The major independent shops do not conduct R&D, but they continued to enjoy increasing sales of their technologically simpler PWBs.
Independent manufacturers of PWBs, for the most part, are relatively small producers, as shown in Table 9. (16) In both 1991 and in 1994, the vast majority of independent producers had less than $5 million in sales. The number of small independents appears to be declining sharply. Whereas 33 companies had sales greater than $20 million in 1991 (with 16 of those having sales greater than $40 million), 50 companies had sales above $20 million in 1994 (with 18 of those having sales over $50 million and 5 of the 18 having sales over $100 million). On the other hand, the number of companies with less than $5 million in sales fell to about 600 in 1991, around 450 in 1994, and the declining trend is continuing.

A. Roles and Relationships among Members of the Joint Venture
Although Digital Equipment (DEC) was one of the companies involved in the original NCMS proposal to ATP, it participated in the project for only 18 months. Its decision to withdraw was, according to NCMS, due strictly to financial conditions at the corporation at that time. DEC's financial condition did not improve-- ultimately leading to the closing and sale of its PWB facilities.
Three companies joined the joint venture to assume DECs research responsibilities: AlliedSignal in 1993, and Hughes Electronics and IBM in 1994. Also, Sandia National Laboratories became involved in the joint venture during 1992, as anticipated when NCMS submitted its proposal to ATP for funding. Sandia subsequently obtained an additional $5.2 million from the Department of Energy to support the research effort of the joint venture. These membership changes are summarized in Table 10.
The PWB research joint venture can be described in economic terminology as a horizontal collaborative research arrangement. Economic theory and empirical studies suggest that research efficiencies will be realized when horizontally related companies form a joint venture, due to the reduction of duplicative research and the sharing of research results. (17) This conclusion is supported in the case study here, as evidenced by the quantitative estimates of cost savings reported by the members, and by the specific case examples cited in support of the cost-savings estimates.
Characteristics of the joint venture member companies are summarized in Table 11. AT&T, Hughes, IBM, and Texas Instruments were four of the leading domestic captive producers of PWBs when the project began; they were also members of NCMS, the joint venture administrator. Although in the same broadly-defined industry (i.e., they are horizontally related), two of these companies, AT&T and IBM, were not direct competitors in PWBs because their PWBs were produced for internal use in different applications. AT&T produced PWBs primarily for telecommunications applications while IBM's application areas ranged from laptop to mainframe computers. Although Hughes and Texas Instruments produced for different niche markets, they did compete with each other in some Department of Defense areas. Hamilton Standard, no longer a producer, purchases boards to use in its production of engines and flight control electronics. AT&T and Texas Instruments are not involved in these latter two product areas. In contrast to all of the other companies, AlliedSignal is a major supplier of materials (e.g., glass cloth, laminates, resins, copper foil) to the PWB industry. In addition, it is a small-scale captive producer of multilayered PWBs.

B. Organizational Structure of the Joint Venture
A Steering Committee, with a senior technical representative from each of the participating organizations worked collectively to direct and control the four research teams to ensure that each was meeting the technical goals of the project. NCMS provided the program management, coordination, facilitation, and interface with ATP for the PWB project. NCMS coordinated and scheduled activities and provided the interface between the administrative functions of accounting, contracts, and legal functions related to intellectual property agreements.

Note: n.p. denotes not a producer of PWBs.
The joint venture was organized to "mimic a company with a chain of command," according to one member of the Steering Committee. According to this member:
The joint venture's research activities were divided into four components:
Prior to proposing to ATP's 1990 General Competition, the members of the research joint venture conducted a systems analysis of the PWB manufacturing process and concluded that fundamental generic technology development was needed in these four components of the PWB business.
Each component consisted of a combination of research areas which:
A multi-company team of researchers was assigned to each of the four research components. The four research teams were involved in 62 separate tasks.
Each team had specific research goals as noted in the following team descriptions.
Materials Team: The majority of PWBs used today is made of epoxy glass combinations. The goal of the Materials Team was to develop a more consistent epoxy glass material with improved properties. The team was also to develop non-reinforced materials that exceeded the performance of epoxy materials at lower costs. Better performance included improved mechanical, thermal, and electronic properties (e.g., higher frequency) to meet improved electrical performance standards.
Surface Finishes Team: Soldering defects that occur during assembly require repair. The goal of the Surface Finishes Team was to develop test methods to use during fabrication to determine the effectiveness of various materials used during the soldering process and to develop alternative surface finishes. These test methods can be applied during fabrication to ensure the PWB meets assembly quality requirements.
Imaging Team: The goal of the Imaging Team was to investigate and extend the limits of the imaging process to improve conductor yield, resolution, and dimensional uniformity.
"Product" Team: Originally, this team was known as the chemical processing team. Its goal was to investigate the feasibility of additive copper plating and adhesion of copper to polymer layers. Based on input from the industry which revealed that this was not the best research path to take, its focus changed as did its name. The revised goal of the Product Team, after studying roadmaps and specification predictions, was to develop high density interconnect structures. (The "Product" Team, like the other teams, carried out research.)
Given the generic research agenda of the joint venture at the beginning of the project, the organizational structure seemed conceptually appropriate for the successful completion of all research activities. At the close of the project, this continued to be the opinion of the members. As a member of the Steering Committee noted:
C. Technical Accomplishments (18)
NCMS released a summary statement of the technical progress of the joint venture at the conclusion of the project. The PWB Research Joint Venture Project accomplished all of the originally proposed research goals and the project exceeded the original expectations of the members. Based on the NCMS summary and extensive telephone interviews with each team leader, the following major technical accomplishments at the end of the project have been identified. (19) The accomplishments are also summarized in Table 12.
(1) Developed single-ply laminates that have resulted in cost savings to industry and in a change to military specifications that will now allow single-ply laminates. (20)
(2) Developed a new, dimensionally stable thin film material that has superior properties to any other material used in the industry. This outcome has resulted in a spin-off NCMS project to continue the development of this material with the goal of commercialization by 1998.
(3) Identified multiple failure sources for "measling". (21) The findings revealed that PWBs were being rejected, but that the real source for the board's failure was not being correctly identified as a problem with the adhesion of resin to the glass.
(4) Completed an industry survey that led to the development of a Quality Function Deployment (QFD) model (discussed below). The model defines the specifications of the PWB technology which are considered most important to customers.
(5) Completed an evaluation (and compiled a database) of over 100 high performance laminates and other selected materials that offer significant potential for improving dimensional stability and plated through-hole (PTH) reliability. Revolutionary materials exhibiting unique properties, and potentially eliminating the need for reinforced constructions, have been identified.
(6) Developed a predictive mathematical model that allows the user to predict dimensional stability movement of various construction alternatives. (22)
(7) Developed the finite element analysis model (FEM), with the Product Team, that predicts PTH reliability.
(8) Developed a low profile copper foil adhesion on laminate process such that military specifications could be revised to allow for lower adhesion of copper. (23)
(9) Developed a plasma monitoring tool. (24)
(10) Filed a patent disclosure for a Block Co-polymer replacement for brown/black/red oxide treatments for inner layer adhesion. This substitute will facilitate lower copper profiles and thinner materials.
Surface Finishes Team: The major technical accomplishments of the Surface Finishes Team were the following:
(1) Improved test methods that determine the effectiveness of various materials during the soldering process, producing the conclusion that one surface finish (imidazole) is applicable to multiple soldering applications.
(2) Commercialized the imidazole surface finish through licensing the technology to Lea Ronal Chemical Company.
(3) Conducted a survey of assembly shops to determine parameters that manufacturers monitor in order to make reliable solder interconnections.
(4) Evaluated numerous other surface finish alternatives, and presented the data at the spring 1995 IPC Expo in San Jose; the paper won the Best Paper Award at the conference.
(5) Filed three patent disclosures: A Solderability Test Using Capillary Flow, Solderability Enhancement of Copper through Chemical Etching, and A Chemical Coating on Copper Substrates with Solder Mask Applications.
(6) Facilitated the adoption of test vehicles developed by the team for development use, thus saving duplication of effort. (25)
Imaging Team: The major technical accomplishments of the Imaging Team were the following:
(1) Developed and successfully demonstrated the process required to obtain greater than 98 percent yields for 3 mil line and space features. (At project start, the industry benchmark was 30 percent yield.) The team also obtained over 50 percent yield for 2 mil line and space features. (At project start, the industry benchmark yield was below 10 percent.)
(2) Developed and put into use test equipment and data processing software to evaluate fine-line conductor patterns for defect density, resolution limits, and dimensional uniformity. (26)
(3) Applied for a patent on conductor analysis technology and licensed the technology to a start-up company-- Conductor Analysis Technologies, Inc. (CAT), in Albuquerque, NM. CAT now sells this evaluation service to the PWB industry. According to NCMS, it is highly unlikely that a private sector firm would have developed this technology outside of the joint venture. Thus, commercializing this technology through CAT, Inc. has benefited the entire industry. (27)
(4) Evaluated new photoresist materials and processing equipment from industry providers, and designed new test patterns for the quantitative evaluation of resists and associated imaging processes.
(5) Developed and proved feasibility of a new photolithography tool named Magnified Image Projection Printing; this tool has the potential to provide a non-contact method of printing very fine features at high yields and thus has generated enough interest to form a spin-off non-ATP funded NCMS project to develop a full scale alpha tool. No results are yet available.
Product Team: The major technical accomplishments of the Product Team were the following:
(1) Developed a revolutionary new interconnect structure called Multilayer Organic Interconnect Technology (MOIT), described as the next generation Surface Laminar Circuit (SLC) technology; and demonstrated the feasibility of MOIT on 1,000 input/output Ball Grid Array packages and test vehicles using mixed technologies, including flip-chip. (28)
(2) Completed an industry survey related to subtractive chemical processes, additive processes, and adhesion. The results of the survey showed that there was not industry interest in the research area; as a consequence, a different research path was taken (with ATP's approval). (29)
(3) Identified chemical properties to enhance understanding of the adhesion of copper to base material, and magnetic-ion plating of metal conductive layers; also developed plated through-hole models and software that are highly efficient and cost effective to run.
(4) Developed evolutionary test vehicles that simulate Personal Computer Micro Interface Card Adapter (PCMICA) and computer workstation products. These test vehicles have been used to pull the development of new materials, surface finishes, and imaging technology by other teams.
(5) Performed several small hole drilling studies and minimum plating requirement studies for PTHs.
(6) Delivered a paper on the finite element analysis model (FEM), developed with the Materials Team, which won the Best Paper Award at the fall 1994 IPC meetings in Boston.

A. Conceptual Approach to the Analysis
The conceptual approach to the assessment of early economic gains from this joint venture parallels the approach used by others in economic assessments of federally-supported R&D projects. (30) Specifically, a hypothetical counter-factual survey experiment was conducted. Participants in the joint venture were asked to quantify a number of related metrics that compared the current end-of-project technological state to the technological state that would have existed at this time in the absence of ATP's financial support of the joint venture. Additional questions were also posed to each team leader in an effort to obtain insights about the results of the joint venture affecting the industry as a whole.
In the 1993 study (Link, 1993), it was determined that only 6.5 of the 29 then on-going tasks would have been started in the absence of the ATP award. At project end, there were 62 research tasks, and it was estimated that about half of these would not have been started in the absence of ATP funding. (31) Accordingly, a counter-factual survey was created to examine that subset of tasks that would have been started even in the absence of ATP support. Each of the project team leaders was briefed about this study at the April 1996, end-of-project Steering Committee meeting. It was decided that the survey would focus on only one limited dimension of economic impact-- namely cost savings attributable to formation of the joint venture, in terms of only those projects that the member companies would have pursued individually anyway in the absence of the ATP supported joint venture. This limited focus has both positive and negative aspects. On the positive side, it ensured participation in the economic analysis by all members of the joint venture. And, estimates of quantified impacts would represent a lower bound estimate of actual economic value of the joint venture. On the negative side, a number of technical accomplishments that would not have come about but for the joint venture have the potential in time to generate large economic benefits to the PWB industry and to consumers of PWB-based products. No aggregate estimate of the potential value of these impacts was attempted in this study due to its early nature, though examples of productivity impacts currently realized by several of the companies were documented. Looking at developments several years downstream should shed more light on diffusion of the technology developed in the project and their benefits in use.
B. Methodology for Data Collection
The methodology used to collect information for this study was defined, in large part, by the members of the joint venture. In particular, members requested that the information collected first be screened by NCMS to ensure anonymity and confidentiality, and then only be provided for the study in aggregate form. Under this condition, all members of the PWB research joint venture were willing to participate in the study by completing a limited survey instrument and returning it directly to NCMS.
The survey instrument considered these related categories of direct impact: (32)
The survey also considered these two broad categories of indirect impact:
Focused survey findings were supplemented with selected open-ended comments offered by respondents; by personal discussions with team leaders and company representatives during the April 1996, Steering Committee meeting; and by follow-up telephone and electronic mail discussions with available members.
Survey Results: Two Snapshots in Time, 1993 and 1996
All members concurred that the joint venture would not have formed by them or by others in industry in the absence of ATP funds to leverage the overall research program. Each member of the PWB research joint venture was asked which research tasks in which they were involved would have been started by their company in the absence of the ATP-funded joint venture. Aggregate responses suggested that only one-half of the tasks would have begun in the absence of ATP funding. The other one-half would not have been started either because of the cost of such research or because of the related risk. Tasks that would not have been started without ATP funding include:
Of those tasks that would have been started without ATP funding, the majority would have been delayed by at least one year for financial reasons. (33)
Regarding the five categories of direct impacts:
Two years into the project, the members estimated a total of 79 workyears had been saved from avoiding redundant research, valued at more than $10 million. (34) At the end of the project,
the members estimated a total of 156 workyears had been saved. The total value of these workyears saved was estimated at $24.7 million. (35) The estimated $24.7 million in savings was based on an estimate of additional labor costs member companies would have incurred if research tasks that they have been willing to conduct individually in the absence of the ATP joint venture were in fact actually carried out individually and without collaboration. (36)
An example of workyears saved by avoiding redundant research was provided by a member of the Steering Committee:
b. Testing Materials and Machine Time Savings
Two years into the project, the members estimated cost savings to be over $2 million from saving in research testing materials and research machine time. At the end of the project, the members estimated the total value of savings in research testing materials and machine time to be over $3.3 million.
Relating to research testing materials savings, a member of the Steering Committee noted:
This member went on to note:
c. Other Research Cost Savings
In the 1993 study, members were asked a catch-all question relating to all other research cost savings associated with the research areas that would have been started in the absence of ATP funds, excluding labor and research testing material and machine time. In 1993, these other cost savings totaled $1.5 million. In the 1996 survey, the same catch-all question was asked, and members' responses gave cost savings of over $7.5 million.
Therefore, quantifiable research cost savings attributable to ATP funds and the formation of the joint venture were $35.5 million, at the end of the project,--$24.7 million in workyears saved, $3.3 million in testing material and machine time saved, and $7.5 million in other research cost savings. In other words, members of the joint venture reported that they would have spent collectively an additional $35.5 million in research costs to complete the identified subset of research tasks that they would have conducted in the absence of the ATP-funded joint venture.
d. Cycle-Time Efficiencies: Shortened Time to Put into Practice new Procedures and Processes
Two years into the project, the members estimated that shortened time to put new procedures and processes into research practice was realized from about 30 percent of the tasks, and the average time saved per research task was nearly 13 months. At the end of the project, the members estimated that shortened time to practice was realized in about 80 percent of the research tasks that would have been started in the absence of ATP funds, and the average time saved per task was 11 months. (38) Members did not quantify the research cost savings or the potential revenue gains associated with shortened time to practice.
As an example of shortened time to put into practice new procedures and processes, a member of the Steering Committee noted:
e. Productivity Increase in Production
Two years into the project, members of the Steering Committee estimated that participants in the project had realized productivity gains in production which could be attributed to research developments in about 20 percent of the 29 research areas. The then-to-date production cost savings totaled about $1 million.
At the end of the project, the members estimated productivity gains in production which could be traced to research developments in about 40 percent of the 62 research areas. (39) The teams estimated the value of these productivity gains in production, to date, to be just over $5 million. And, given that the PWB research joint venture's research has just completed, future productivity gains will, in the opinion of some team leaders, increase exponentially. (40)
One example of productivity improvements in production relates to switching from two sheets of thin B-stage laminate to one sheet of thicker B-stage laminate. One member of the Steering Committee noted:
A second example of productivity improvement relates to dimensional stability. In particular, another member of the Steering Committee noted:
A third member of the Steering Committee reported:
And a fourth member commented:
Two categories of indirect impact were identified which already are beginning to extend beyond the member companies to the entire industry: advanced scientific knowledge important to making PWBs, and improvements in international competitiveness. For these types of impact, descriptive information was collected to illustrate the breadth of the impact, but no effort was made to estimate aggregate dollar value or to segment them according to tasks that would or would not have been begun in the absence of ATP funding. This approach was based on advice of the Steering Committee which felt that attempting aggregate dollar valuations at this time would be extremely speculative in nature.
a. Technology Transfer to Firms Outside the Joint Venture
Two years into the project, the members estimated that 12 research papers had been presented to various industry groups; 40 professional conferences fundamental to the research of the joint venture had been attended; information from the research tasks was shared with about 30 percent of the industry supplying parts and materials to the PWB industry; and personal interactions had occurred between members of the Imaging Team and suppliers of resist materials to the industry.
At the end of the project, a total of 214 papers related to the research findings from the PWB project had been presented, 96 at professional conferences and 118 at informal gatherings of PWB suppliers and at other forums. Additional papers were scheduled for presentation at the time of this study.
Members of the joint venture offered the opinion that such transfers of scientific information benefited the PWB industry as a whole by informing other producers of new production processes. They also benefited the university research community as evidenced by the fact that these papers are being cited in academic manuscripts.
Members of the Materials Team attended 10 conferences at which they interacted with a significant portion of the supplying industry. Specifically, they estimated that they interfaced regarding the PWB project with 100 percent of the glass/resin/copper suppliers, 100 percent of the flex laminators and microwave laminators, 90 percent of the rigid laminators, and 50 percent of the weavers.
Members of the Steering Committee were asked to comment on the usefulness, as of the end of the project, of these technology transfer efforts. While all thought that they were important to the industry, one member specifically commented:
Another member noted that his company relied on an independent PWB shop for dense boards. A measure of the success of the joint venture's technology transfer efforts is that this independent supplier, not a participant in the joint venture, has also increased its yield of these boards.
All members agreed that it was premature, even at the end of the project, to attempt to estimate in dollar terms the value to the industry of these knowledge spillover benefits.
b. International Competitiveness Issues
The health of the domestic PWB industry is fundamental to these companies becoming more competitive in the world market. At a recent meeting, NCMS gave its collaborative project excellence award to the ATP-sponsored PWB project. At that meeting the NCMS president credited the project with saving the PWB industry in the U.S. with its approximately 200,000 jobs.
As shown in Table 13, the members of the PWB Research Joint Venture perceived that as a result of their involvement in the joint venture, their companies have become more competitive in certain segments of the world market such as computing, the fastest growing market for PWBs. Although any one member company is involved in only one or two market segments, thus limiting the number of team members' responses relevant to each market segment, all members indicated that their companies' market share either stayed the same or increased as a result of being involved in the PWB project.
Likewise, as shown in Table 14, members perceived that the domestic PWB industry as a whole has increased its competitive position in selected world markets as a result of the accomplishments of the joint venture.
Most respondents expressed an opinion on how the PWB Research Joint Venture has affected the industry share in the different segments of the world PWB market. The responses indicate that the PWB project has increased industry's share in every market segment, with the strongest positive responses in the computer and military segments. No member was of the opinion that they or other members of the joint venture had increased their share at the expense of non-members, and this can be attributed to the fact that the results of the PWB project have been widely disseminated.
In addition, some members of the Steering Committee felt that the research results from the PWB Research Joint Venture had the potential to enhance the international competitive position of the U.S. semiconductor industry. It was the opinion of one member that:
Through this program, the PWB industry is learning to produce higher density PWBs with finer lines, reduced hole sizes, and new surface finishes. This is allowing the semiconductor industry to decrease the size of their component packages or eliminate them totally. This should have a pronounced effect on the competitiveness of the semiconductor industry in the future, although there is no evidence to date.

D. Summary and Interpretation of the Survey Results
ATPs funding of the PWB Research Joint Venture Project has thus far had a number of direct and indirect economic impacts. Of the direct impacts, the largest to date has been the increase in R&D efficiency. The project achieved at least a 53 percent reduction in overall research costs. The increase in research efficiency has in turn has led to reduced cycle times for both new project development and new process development. Collectively, the result has been in productivity improvements for member companies and improved competitive positions in the world market. As a result of knowledge dissemination activities by members of the joint venture, capabilities across the entire industry are expanding. These technology advancements are thus improving the competitive outlook and world market share of the U.S. PWB industry.
The survey findings associated with the above direct and indirect economic benefits are summarized in Table 15. Therein, the categories of direct economic impacts to member companies are separated into those for which dollar values were obtained and those for which dollar values were not obtained, so-called quantified and non-quantified economic impacts.
The survey results described in the previous sections and summarized in Table 15 should be interpreted as only partial and preliminary estimates of project impacts. First, although ATP funding of the joint venture has led directly to research cost savings and early production cost savings and quality improvements, the bulk of the production cost savings and performance gains will be realized in the future both in member companies and in other companies in the industry as the research results diffuse and are more widely implemented. As such, the valued economic impacts reported in Table 15 are a conservative lower-bound estimate of the long-run economic benefits associated with ATP's funding of the joint venture research.
In the methodology implemented thus far, data collection has focused on gathering from participants best estimates of cost savings and economic benefits, relative to a counter-factual situation without the ATP. The participants in the PWB Research Joint Venture are obviously those in the most informed position to discuss research cost savings, potential applications, and economic consequences that they have realized from the results obtained. The methodology does not as yet include consideration of market determined economic benefits deriving from the joint venture research. Full impacts across the marketplace cannot be observed instantaneously at the end of the project, but only in the future as research results diffuse and become embodied in PWB products.

Note: * These impacts are based only on those research tasks that the members thought they would eventually have done without the ATP, and not the cost and time savings associated with the new capabilities resulting from those tasks that they would not have done at all without the ATP.
During the April 1996, Steering Committee meeting of the PWB Research Joint Venture, the members of the committee were asked to respond to the ten statements in Table 16 using the response categories of strongly agree=4, agree=3, disagree=2, strongly disagree=1, and no opinion=0. Beside each statement is the mean response; no member responded with no opinion. (42)
As the response scores indicate, the Steering Committee overwhelmingly agreed about the impact of the PWB Research Joint Venture on commercialization, refinement of manufacturing technologies, and competitiveness. The strongest agreement came regarding the future impact of the PWB research joint venture on the industry (Statement 4 in Table 16).
Lastly, the members of the Steering Committee were asked to complete the following statement: My company has benefited from its involvement in the PWB joint venture in such non-technical ways as... Representative responses were:
Lastly, the members were read the goals of the ATP as stated in its enabling legislation (and noted in Section I of this report). Albeit qualitative information, the members of the Steering Committee of this joint venture generally agreed that the ATP had indeed fulfilled its stated goals in the case of the PWB Research Joint Venture.

Automotive
| World Market Share Has |
It
is my impression that the international competitive position of the
semiconductor industry has been affected by the accomplishments
of the PWB Program in the following ways (please describe): |
1. In April 1993, two years after the five-year printed wiring board joint venture was funded, a summary of the early-stage effects was prepared (Link 1993). This updated report considers the cumulative economic impacts identifiable with the joint venture up to the time of its completion.
2. This section of the Omnibus Trade and Competitiveness Act of 1988 is also known as the Technology Competitiveness Act.
4. The National Center for Manufacturing Sciences (NCMS) is the Nation's largest not-for-profit collaborative research consortium. In cooperation with government and industry, NCMS is working to meet the challenges posed by global competition to the American manufacturing community. NCMS served as project administrator.
5. These end-of-project cost figures were provided by ATP.
6. This section draws from Flatt (1992).
7. Definitionally, a PWB consists of a conductive pattern on a common surface to provide point-to-point connection of discrete components, but not to contain printed components. A PCB is a conductive pattern composed of printed components, printed wiring, or a combination thereof, all formed in a predetermined design and attached to a common surface. See Institute for Interconnecting and Packaging Electronic Circuits, IPC (1995a).
8. Based on 1994 data, multilayered boards accounted for $3.92 billion of the $5.96 billion rigid PWB market (IPC 1995a).
9. Original equipment manufacturers (OEMs) are manufacturers that produce PWBs for their own end-product use.
10. See Council on Competitiveness (1991).
11. See Council on Competitiveness (1996).
12. Multilayer boards consist of alternating layers of conductor and insulating material bonded together. In comparison, single-sided boards have a conductive pattern on one side, while double-sided boards have conducting patterns on both. See Microeconomics and Computer Technology Corporation and IPC (1995).
13. These definitions come from IPC (1992). In years prior to 1994, there was a single category of computer and business equipment.
14. According to NCMS sources, the profits on PWBs are small. As OEMs/captives continually re-evaluated the strategic importance of maintaining the large R&D overhead burden associated with their PWB production process, they opted to decrease production in favor of purchasing PWBs from independents.
16. Similar information is not available for OEMs.
17. See Link and Bauer (1989).
18. These technical accomplishments were compiled with the assistance of Ron Evans, then of NCMS.
19. As discussed in the following section, economic impact data were collected regarding these technical accomplishments.
20. Single ply laminates is one of the best of the technical accomplishments that are already being implemented; it is generating cost savings in the industry, and especially for those companies that supply to the military. Many other technical achievements, such as the Magnified Image Projection Printing Tool (see Imaging Team below), are still in the process of full implementation and could have even greater impacts.
21. Measling is the separation or delamination at the glass resin interface in a PWB. This separation results in a void that can allow moisture to be trapped in the board, causing a short circuit. Detection of measling can result in the board being rejected. If not detected, the board will eventually fail to operate (e.g., the board will short circuit).
22. Multilayered boards move during fabrication. This model predicts that movement thereby ensuring that the components on each layer will be in alignment.
23. The development of low profile copper adhesion will generate cost savings to the industry because less material is needed in production, especially for those companies producing under military contract.
24. This tool is used for end point detection and has already been transferred to industry by Sandia acting through SEMATECH. A patent disclosure has been filed.
25. A test vehicle is a device that is designed and manufactured to test new technology by simulating or emulating a product or family of products. NCMS reported that these test vehicles are also used outside of the research joint venture on other NCMS research projects.
26. The test methodology also provides statistical process control data. Objective tests are necessary to ensure that new imaging techniques are suitable for production use.
27. See Rhodes (1996) for a description of this start-up company.
28. IBM is continuing research on MOIT on its own.
29. As previously noted, this team was originally called the chemical processing team.
31. The number of research areas increased from 29 to 62; as the companies worked together, new problems were identified and tasks were identified to solve them.
32. Impact data were requested from each member by project, although it was understood that only aggregate totals would be made available for this study. In practice, however, because of the integrated nature of the research, companies generally reported the total research cost saving from the joint venture's activities to NCMS.
33. This information comes from qualitative responses; specific time periods were not obtained individually for each of the 62 research tasks. As one member of the Steering Committee noted about this one year time savings: "Time to market is everything. Process knowledge became available one year sooner. The PWB industry recovery occurred one year sooner and is still growing."
35. In general, companies estimated the value of workyears saved by imputing their standard 1995 rates. According to NCMS, these rates ranged from $107,000 to $200,000 per workyear, including an average burden rate of 100 percent.
36. See Link, Teece, and Finan (1996) for related examples of like labor savings that result from joint venture research.
37. No projection as to when this might occur was offered by members of the Steering Committee.
38. Members of the research teams were not asked to value research-related savings from shortened time to practice, based on advice from the members during the pre-testing phase of the survey. The pre-testing group based this advice on previous experience with scientists who, when asked to quantify such savings, would simply associate the total cost savings from a month saved in research time with the labor cost of an additional man-month of effort. Certainly, such an evaluation would result in an under estimate of the economic advantages of completing research sooner than would have otherwise been the case. Such related economic advantages include the non-labor research costs saved and the sooner-than-would-otherwise-be-the- case increase in sales.
39. It was not possible to segment productivity improvements attributable to the group of research projects that would have been undertaken absent ATP funding from those that would not have been undertaken, due to the complementary effects of research project results on production.
40. Quantitative estimates of future productivity gains were not offered by the members.
41. There are more than 1,000 solder joints per PWB.
42. The representative from Sandia National Laboratories chose not to participate in this exercise.
43. These seven market segments were created by the IPC.
