We find that baking PCB assemblies at 90 degrees C in a Blue M forced air oven is safe for most all PCB's that we have encountered over the past 12 years. We remove any external plactic hardware that may be attached to the assembly and also like to

I know, I know. It's not a "solution", per se, because it's a bandaid for bad fabrication, packaging, and storage practices. Still, it's a reality with our overseas CM that has a plant in a very humid environment. Is 16 hours @ 105C the safe way to

For ICT purposes I may need to print solder paste on 0.015" test vias. No-clean is not an option for this assembly and OA seems the only choice. Can flux be safely removed from inside the via from the other side during a standard water wash process
