Spray fluxing VOC free, as operation HOURS before wave solder

At the risk of painting with too broad a brush: QEs are like seagulls: fly in, make lots of noise, crap all over things, then fly away. Back to the knob turning vs. analysis debate. Part of it may be different industries. We're in the high reliab

Hi Guys, We prints solder paste on via hole as the holes are used as the test points. This is a clean process. In normal production, upon completion of a primary side, board will proceed to secondary process immediately. The problem happened when
