Hello, I have a question for electronic manufacturers. I would like to know in which cases a solderability test for component leads should be done? Should it be done for all kind of parts or only for those bought from brokers? Also, how often th

I have to agree with the fat green guy. And with Real Chunks too. You should also run a matte mask on your board. This will help in preventing shorts.
