Many PCB designers are interested in taking advantage of Multichip Modules, but are unfamiliar with the technology. While the design process is very much the same, MCM manufacturing processes vary dramatically. MCM routing requirements are dictated by the manufacturing process and types of components. Components mounted on MCM substrates are predominantly, if not exclusively, bare chips. As a result, the component body and I/O pins are no longer constrained to industry standard pin counts and form factors as are packaged components...

Due to the arrayed nature of the Computed Tomography (CT) Detector, high density area array interconnect solutions are critical to the functionality of the CT detector module. Specifically, the detector module sensor element, hereby known as the Multi-chip module (MCM), has a 544 position BGA area array pattern that requires precise test stimulation. A novel pogo-pin block array and corresponding motorized test socket has been designed to stimulate the MCM and acquire full functional test data. (...) This paper and presentation will focus on the socket design challenges and also key learnings from the design that can be applied to general test systems, including reliability testing. The secondary focus will be on the overall data collection and graphical user interface for the test equipment.

This article presents the first time that an millimeter-wave (mm-wave) multichip module (MCM) with on-demand "smart" encapsulation has been fabricated utilizing additive manufacturing technologies. RF and dc interconnects were fabricated using inkjet printing, while the encapsulation was realized using 3-D printing. Inkjet-printed interconnects feature superior RF performance, better mechanical reliability, and on-demand, low-cost fabrication process.
