All posts were well-intended, and I understand the, "have you tried this", or "have you tried that" approach. Rafa's was the only person who actually "DID IT." That's what i was looking for. In the heat of battle when you're getting chewed out for

Hi All! I remember reading and seeing some (maybe Loctite) product which could be used to fill stencil apertures, but now when I need one, I cannot find it. Or anything like. Can some one please guide me? And with filling I mean permanent filling, n

I have a job that requires a minimum of 3% lead in all component terminations. Anyone doing DOD out there with the same? How do you get around this with R's and C's especially? I believe we would be OK if the terminations were not pure tin as well bu
