In 90% humidity it’s easy to get condensation. Condensation will create electrical failure when the board isn’t conformal coated. In your case the failure disappears when the humidity level drops so to me it’s unlikely that the flux has anything to d

We've been using a newly installed DI re-circulating system. It's been a big headache. Mostly understanding what causes our resistivity to be unpredictable. I think I've got a handle on that part now. The system consists of a Carbon,HMR(chealet),Cati

Be careful about the material you choose. All the materials out there are basically glass-filled epoxy composites, but they are different blends with different fillers. Some of them have carbon in the matrix to make them ESD safe, but it also short

CERAMIC CIRCUITRY Starting with hybrid thick film circuits in 1965 at Sperry Flight Systems, I have been involved with ceramics (usually aluminum oxide) as the substrate material. Then, we developed "multilayer" circuitry (replacing "cordwood" module
