Adam, Ha yes the joy that is wave soldering, and don't we love customers that forget the simple little things like putting connectors in the right way! It's a common thing and one way to get round it is to angle the cards towards the wave, typicaly

Folk's, I'm just tying up some loose end's on my Master's Thesis on solderballing @ wave soldering and the effect the topography of the mask / PCB has on it. I was wanting to do a straw poll on you guy's as to the type of resist's you are using Glos

Here's a question for you to mull over. I've got a PCB that is 4 millimeters thick, that's about 160thou of USA money if you like it that way. The question is IPC reg's for hole fill say it should be a min of 75% hole fill and 50% on ground planes. A
