It sounds like a bit too much solder on the PWB, caused by too large a pad for the lead it will contain. In that case solder reduction is the way to move forward. What are the options there? 1. New stencil or stencils - (not desirable) 2. Increas

Thank you guys. As we are speaking I keep examine the problem and here is what I got so far. 1. I measured the temperatures on my profile and the lead is hotter than the board. The lead goes 12 seconds earlier than the pad and is taking the solder.

I've always approached it like this: Design your processes and perform your work to class three standards, and inspect to the standard that is acceptable. That is, all work should be performed to the highest degree of quality. When the work is ins

Hi Evtimov 'hege gave you a plausible explanation for what's going on with solder running-up the lead of your components: TOO MUCH METAL!!! I've got different one. This explanation goes along the way that you're thinking, but just opposite. The rea
