Posted wave solder paper to library and my 2 cents on intermetallics

Electronics Forum | Sun Jun 20 16:45:48 EDT 1999 | Chrys Shea

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

A user of one of our components exceeded the floor life of some plastic BGA components. They did do a pre-bake prior to SMT reflow but only 72 hrs at 40C and not the recommended 12 hours at 125C. I've recommended accoustic microscopy to look for popc

| In past PCB designs I have cleared all traces from all layers | (except pwr/gnd) from fiducial area. It has come to my attention that this is only necessary on the side where fud is placed. Which is the correct method of design using a fidicial?
