James, If you have a true MSD issue, then baking them AFTER your reflow is not going to fix the issue. I would have to agree with GS and look at trapped cleaner media (if your not No-clean) under the components, or inside connectors. If your runnin

Hi Kevin, Sorry for the delay in responding to your question. I have been trapped in Australia (not a bad place to be trapped I may add). The scale in your cleaner is not usually caused by the chemical used in the wash cycle (although Armakleen ha

Thank you. I do feel that the document is very lacking in detail. It mostly says "yes, it needs cleaned. Make sure the cleaning process doesn't screw it up". The majority of boards that get wiped are already populated on the other side. So that lim

Your question may be answered in two parts. First, if you are using a water soluble (OA) paste, then water is an excellent �solvent�. Water, in one way or another, is used to clean all fluxes and pastes from PCB�s. In some cases, a chemical is add
