As Russ said, you do a DOE beforehand. BUT Maybe we are missing something, we do SPC after the wave (1/5) to catch defect trends and fix them with a minimum of inspection. If you are running a 2,000 piece pull, are you that confident that your origin

I'm not sure if anyone mentioned the single most important factor. p.m.'s. If the nozzles are getting dirty and clogged it's not going to do a great job of picking parts up. Don't think in terms of variation. It's there it's unavoidable and undet

I am looking for advice on sourcing a x,y digitizer to create pick and place files, off-line, rather than programming with the machine. I could use original gerber data or create the placement coordinates with the digitizer. Also, references to equip
