Agree with Phil , it's basically a flash plate , and not quite to last century standards, but as i stated previously few times : Horses for courses (commerce/applications)will dictate specifications more and more : i opted out of selective platings decades ago , and that time it was a MIL heresy : validated (NiAu) with 1M+ cycles in both telecom and med. boards . Sounds like you have commercial application at hand with some 5-10y life span; with fairly set connectivity: with little justification of building to higher application standards. You may be correct that it is indeed conversion goof , but looking back i never gave an ounce unless i proved (enviro/cycled) it's needed. VP used to shake his head as well ("you can't go this low"), but some say the proof is in the pudding ; saved millions by now by designing to the task (aka toyota) . Overchromed monuments ain't gonna to fly in 3M with design cycles 6-12 months . Just a practicioner's opinion Ken (got a compliment once as "real" engineering) Composites in general went that way decade ago .

I thought it is too low as we even specify 3-8 micron inch on Ni-Gold board. .00003" is 30 micro-inch which I considered 3 micro-inch. Conversion goof-up.
