Pallets will not work in this case because the wonderful designers put 0402's between the legs and all around the legs of the thru-hole connectors. There are 18 thru-hole connectors on this board and 200 - 0402's around them. The 0603's that are al

pr is 100% correct, can't have visual inspectors touching up for the reason he states. I have always seen that- when in doubt they will always "touch up". Touching up is always a bad thing. Looks like you have some problems that need fixing to elimin

First, we expect voiding in imm silver to be similar to ENIG. We expect more voiding in OSP than other common solderability protection. Second, choosing a solder paste, which does not contain resins and activators that decompose at higher temperatu

Over time, you might see problems with delam., blistering and warpage if using FR4 carriers. Depending on volumes, you might consider using durostone or some robust material like that for the production runs. Keep in mind that switching materials w

I'd be happy to tell my customers that they need to provide more parts...the problem is, we specialize in short runs. So, if the customer pinches pennies, and only buys 50 pieces for 50 piece demand, I need to be able to deal with it. Hence, the
