I dug through my big box of office crap and found the disk with my technical papers. I posted the one on process control in the SMTNet library. It covers a lot of ground on what causes defects in the wave (too much or too little of something), and

Hello all, One of our PCB manufacturers coated a through hole connecters vias with solder mask. The only IPC references that comes close to describing this problem is 2.9.2 Registration to holes, and subsequent specification 6.3.1 PTH � Vertical fil

Hi everybody, First of all, to have process under 100% control you should have AOI after every active process in the pcb assembly line : - Post printing (2D or 3D Solder paste inspection machine); - Post reflow; - Post selective(wave solder). It i

Hi Steve-O, Good question(s). This process was set-up by an engineer that had a PhD in statistics, took him a year to develop and then thru it over the wall at us. The biggest problem we saw was SPC to measure solder volume. SPC is good for measu
