Q1. Do we really need to follow the IPC J-STD-001 Solder purity? A1. Yes, you should control impurities in solder. Further information: * "Allowable concentration of contaminating elements in solder: impurities are harmless unless their level goes to

There is evidence of lead being used in soldering 5000 years ago in Mesopotamia. Not a big issue for most people doing SMT but the poster should also understand why percent metal is adjusted for different solder paste alloys. You print by volume b

I am looking for any information or testing data done on the amount of weight that can be held by a bga package based on size of the solder sphere and number of spheres. I am reflowing components with a bga package on the opposite side and looking f

You weren�t clear but I assume the problem is not widely distributed and affects only a few parts on each board. Do this trick: * Cut a ~1� piece of fairly serious wire, like 18 or 12 AWG. * Strip the insulation. * Gear-up with gloves, glasses, and

Could be. What are your profiles? 2) Au finish fail => Could be, but that the connections can be made with hand soldering makes this a low probability cause, assuming the activity of the flux used in hand soldering is not significantly different fr

No you're not stupid, they will melt if the top of the board gets real hot. I was lucky most likely in that ours were usually off of the board surface. anything that will hold the weight material will work. Now that I think about it my shot bags w
