Why reinvent the wheel, Bart? You can buy a thermal barrier from one of the logger manufacturers (M.O.L.E., KIC, DataPAQ, etc). They come in varying sizes and temperature ratings. Maybe you can find one that suits your unit. Good luck.

I have this same problems on the flex i use, most of which has an ENIG or immersion silver finish. About the only thing I know to do is have your supplier package it in a vaccume seeled bag to keep it from oxidizing. Otherwise you end up having to

I believe we are seeing some wetting issues as we have tried to bake these assemblies ourselves. Our PCB supplier is coming in next week to address the issue. Is there a rule of thumb or formula for determining correct parameters. Thanks
