TechNet,

I use a B/P that is .187".  A supplier indicates having difficulty with
HASL as a finish because the board is too thick and is recommending we use
Au.

There are pressfit, SMT and PTH connectors on the B/P.
There are some Rs and Cs as well as some small ICs (SOIC), nothing fine pitch.

If anyone has a B/P of this thickness and/or components similar to this,
what finish are you using and would you recommend it?  Are there any issues
with intermetalics or embriddlement with gold??

All positives and horror stories appreciated.

Tks.....DT
