To close the gap in IC substrates, buyers need skin in the game.

The CHIPS Act was passed more than a year ago and not one federal dollar has yet to be awarded – although private industry has committed and started to spend billions. Once funded, the new, more advanced foundries will take years to build and start operations.

When produced, however, the chips will be useless until they are packaged and mounted on PCB platforms. The facilities, materials and knowhow to produce the substrates used to package them remain primarily in Asia – including China.

Notably, the cost to build and equip the necessary substrate and PCB facilities to produce HDI and UHDI (ultra-HDI) circuitry in volume is substantially more than that of a typical PCB or flex circuit factory, but far less than that needed for a foundry.

To provide incentives, US Representatives Blake Moore (R-UT) and Anna Eshoo (D-CA) this year introduced H.R.3249 – Protecting Circuit Boards and Substrates Act. This bill is the second iteration of this effort and has a long way to go in gaining cosponsors and approval.

Creating sustainable Western PCB and substrate sources will take time, and will not necessarily be in the country of use. Today just a handful of American and Western companies have the technology to produce some level of UHDI circuitry. To develop a secure source, the US will need more than government words, resolutions, bills and funds with heavy ropes (not just strings) attached: It needs active OEM investment and participation.

The PCB East keynoter gives a roundup of innovative technologies to come out of the pandemic.

We have gone where no mask has gone before! The Printed Circuit Engineering Association (PCEA) held its first regional conference and exhibition in Marlborough, MA, in April.

A resurrected PCB East drew attendees from as far as the West Coast and Florida. There is nothing like in-person contact. The social aspect of networking has been missing for far too long. The enthusiasm of the attendees bodes well for future face-to-face regional gatherings.

It was great to see so many old friends in the real world, while meeting new young engineers and entrepreneurs such as Yitzi Ehrenberg and David Kanarfogel of Conformant, who have developed a new additive circuit process based on an innovative CVD system.

IPC and retired industry legend Dr. Laura Turbini joined many notable attendees, including Dr. Hayao Nakahara, Anaya Vardya, John Vaughan, Chrys Shea and Peter Bigelow, president of the SMTA Boston Chapter.
