Wash them in Saponifier frequently at around 40C rinse and dry thoroughly. I would imagine it could be going white if you have a resin system in the flux that is not water soluble. Ensure you are using suitable pallet material up to 300C for Lead Fre

Hi expert, we have one lead frame product proposed to send to flux clean recently. The problem here is the frame is attached with high temp tape. After flux cleaning the frame, the tape turns out deformed in which we think it was due to chemical reac

It could be lack of preheat or flux. You can verify the flux by hand applying. I'll bet it's lack of preheat though. That's usually the case with selective solder.

Is anyone wave soldering 0603 leadfree succesfully? We have no problems soldering them leaded, but lead free we see a lot of random skips and some shorts. We use SAC. We have tried different fluxes, flux settings, playing around with preheat, sol

We've got an auto fuse clip (a pair of tin/nickle spade type receptacles joined with a nylon bridge piece) giving us fits. The pins on this thing have a right angle profile (symmetrical "L" shape) and make great flux traps. No amount of tweaking pre
