Hey Cartman: Recently, I was over at a plant that does ICT on RMA fluxed boards and asked them about flux residue on test probes. The test machine operators: * Think flux residues are a pain in the gluteus maximus. * Change probes (from a collectio

Thanks for info regarding rotating probe head. We do not recommending to use this probes as it may damage bare board as it will pierce thru board and will shorted etches.. Avoid using this probe for PWBA

Hi all, Sorry for the late reply..I am sure it is flux residue..Found no such symptom as Grey mention above. This is non clean process and no way we can clean this whole big board(Server) with any kind of flux removal...Currently, the ICT probe pre

in all actuality, you are both right. Alpha metals does have the toughest/hardest noclean residue that I have seen. When changing to no-clean FLUX you should run different probes. So back to square one. You're both right so who's gonna win?

Hi I have a funny feeling that Mike Konrad and I know each other from IBM-Endicott days, yet I could be wrong. It would be funny?? Mike gave a good answer. The Rosin or Rosin Mildly Activated Flux (RMA) if on the board at ICT (In Circuit Test) wil

Thanks for the response Dave. FYI: In my experience using the light cure adhesive, I have found that the newer the adhesive is the less prone it is to popping off during a reflow cycle. Also I have found that it only takes a very small amount to sec
