There is an excellent IPC standard, IPC-9241 Guidelines for Microsection Preparation, but I cannot remember if it discusses Back Plating and I do not have a copy here in front of me. When I get back Monday I will check.

Fellow TechNetters:
Is there an IPC Standard and/or guideline line which stats or recommend that if thin gold plating is to be measured by cross section then Back Plating Process should be conducted.
