just check if the pad and component terminal was traces of solder, if have? try to reduce preheat temp and solder bath temp... reason why solder not adhere because of component lead type, if more heat you apply solder flows and not completely adhere.

We are experiencing voiding on one of our lead-free assemblies on every part. The voiding only occurs underneath the parts and not in the solder fillet (see pic). We have tried baking, curing, washing, multiple pastes and everything else we can think

So, I just learned that alpaca isn't just a cousin of the llama, it's also a Cu/Ni alloy (imitation silver). Creeped me out at first... When you say "poor filling and no solder", are you referring to wetting problems? Do you have any photos you co

Bruce, Since we had spares, I replaced the X wagon cables, XFMB cable, nothing. FFX Cable, nothing. Swapped mot cards, nothing. Vaccum seal, nothing.At this point I truly believe the problem is either on the theta encoder or the theta motor. Unfortu

We've just acquired a batch washer at an auction, and want to install it as a closed loop system. The only problem is I have no idea where to turn or what to look for for a drain filtering system that will allow us to make it a closed loop system.
