New Project Launch

The Final Finish Layer Deposits for High Frequency project was completed in 4Q2025. PCB final finish layer deposits contribute to high frequency signal distortion (decibel loss) with the distortion increasing as the operating frequencies are increased. In this initial project phase, more than 20 Ni-less finishes were evaluated and clear trends in high-frequency loss performance were identified. Because signal-distortion sensitivity increases above 50 GHz, measurements were made to 110 GHz.

Two new phases of this project have been launched:

Phase 2 will narrow down candidates from the final finishes evaluated in Phase 1 and newer finishes such as Thin-Ni ENIG. We will then conduct a series of evaluations to compare their reliability and durability against conventional ENIG and ENEPIG.
In parallel, Phase 3 will focus on gaining a deeper understanding of the low-loss characteristics observed in Phase 1. Selected final finishes will be applied to the same test coupons used in Phase 1, with close attention to the as-is copper surface roughness and the thickness of Au, Ag, and Pd layers directly on copper. We will analyze the increase in insertion loss across different frequency ranges.

HDP Annual Member Meeting

Save the date!

After three successful member meetings in 2025, planning for the HDP Annual Member Meeting is progressing. The meeting is scheduled for March 4 and 5, 2026, and will be hosted by Underwriters Laboratories (UL) in San Jose, CA.

In addition to the usual project updates, a keynote address will be delivered by Joe O’Neil, Principal OAA Ventures. The subject of the keynote is: The PCB Market Catalyst (PCBMC)

The PCB Market Catalyst (PCBMC) is designed to rapidly deploy UHDI manufacturing capability into the U.S. electronics industrial base and accelerate technology transition from development to production. In parallel, PCBMC is intended to expand the domestic electronics manufacturing base by aligning demand, process capability, workforce readiness, and manufacturability. By acting as a neutral public-private partnership (PPP), PCBMC will reduce adoption friction, compress learning curves, and enable broader access to advanced interconnect technologies that are currently capital-, talent-, and yield-constrained.
