Anyone out there got more than their fair share of problems with
solderability on PCBs with electroless Ni/Au surface finish at the moment?

We have had problems before from a supplier, with Ni/Au boards poorly dried
after the final rinse and others with copper contamination in the acid clean
bath, but this looks like it might be a new cause. Phosphorous content does
not seem to be relevant.

Thanks
