Ask HN: Good vendor to analyze PCBs via cross section

1 points by zafka ↗ HN
Has anyone had tests done where they potted a PCB in clear epoxy and then did cross sections to check thicknesses and uniformity of gold layers? Or for that matter, favorite labs who do this and other tests.

Microtech labs in Plano Texas does a good job of this. I use them fairly often for both PCB and IC level cross sections.
