Printed Circuit Board Fabrication and AssemblyPrinted Circuit Board Fabrication
As the “brains” of sophisticated electronic devices used in experiments throughout the Laboratory, specialized circuit boards are required. These Printed Circuits Boards (PCBs) are exposed to such extreme environments as high radiation, humidity, and cryogenic temperatures in a wide variety of experiments. Circuit boards for these diverse applications are not readily available commercially. Our facility is capable of designing, fabricating and assembling unique PCBs for Instrumentation Division research activities and for other Laboratory programs and activities requiring such specialized circuit boards. Recent expansion and upgrading of this facility with state-of-the-art equipment has made it an invaluable resource to the Division, for BNL’s scientific community, and for our international collaborators. The printed circuit board fabrication group produces custom circuit boards from the engineer’s initial design to the finished board, with the capability to produce features such as fine holes for via structures and components, ultra fine width and pitch conductive circuit traces. The facility also has the capability to fabricate boards using a wide range of materials like Kapton, Polyamide and other low loss materials, etc. The facility has an optical inspection station in its process line, which is used for inspecting individual layers for defects such as under or over etched traces, shorts, or opens in traces. The facility has been and is actively involved in producing prototypes for various Brookhaven experiments and collaborations.
Some of the experiments for which the facility has provided its

Recent expansion and upgrading of this facility with state-of-the-art equipment has made it an invaluable circuit board resource to BNL's scientific community and international collaborators. The facility can now prepare multi-layer fiberglass boards with drilled holes of unprecedented accuracy. Also, with the new equipment, the conducting circuit lines can be made much thinner, and the spacing much closer, than those on commercially, mass-produced boards - as little as 1/1000th of an inch. Printed Circuit Board AssemblyThe circuit board assembly group in Instrumentation is a cost-effective means of assembling specialized custom circuit boards or for performing any kind of rework on existing fixtures or off-the-shelf electronics. The personnel closely integrated into the web of the electronics group in Instrumentation are skilled in the art of assembling electronic components into the circuit boards fabricated either at the facility or elsewhere. The boards prepared by this group then make their way into an experiment or onto an engineer’s test bench. The group utilizes a wide range of equipment for assembling large or very small components to silicon die as small as 2 mm × 2 mm with as many as 40 input/output pads in them. Capabilities
