We are looking for AOI for post solder inspection with short setup times for high mix assembly. Also the solder joint of J-Lead components should be inspected. We found two suppliers for such systems, Orbotech and Viscom. Can anyone help us to det

Chris: Typical non-wetting causes are: * Poorly controlled soldering process * Incorrect material * Surface contamination * Insufficient preheat * Misapplied solder mask * Shadowing Without intending to insult you, all of the causes of non-w

Chris: Thanks. SMTnet has a "Library." Buried deep within it is a listing of terms. The following is from that listing: Shadowing. When a component blocks the heat or solder wave flow from certain areas of the printed circuit board, resulting in

Hi, I'm looking for vendors that manufacture connector pins that would solder onto the edge of a small SMD pcb so that I can mount it as a SIP onto a larger PCB. Better yet, are there small diameter pins that can be soldered into thru-holes so the SM

No, but answer me this? 1 What type of BGA? 2 What's the wave process, materials and temps? Are you waving the BGA or top-side flowing it? 3 If the BGA is plastic, what are you doing to prevent/remove entrapped moisture before solder processing?

I once had similar problems. It went away when I switched to a different brand of solder paste. When I switched back to the previous brand of paste the problem came back. I don't know why but the solder paste brand made a difference. go to: www.
