It makes a difference what the normalizer is. We calculate solder ppm and placement ppm separately for each assembly. Solder ppm = #solder defects*1E6/(Qty boards*#solder joints per board). For us this number is easily less than 50 and sometimes

Thanks, Mark. Actually we already have an established mark. We use 500ppm (99.95%) as our acceptable level. Problem is, someone (another manufacturer) told someone else (our pres.) that THEY build to 50ppm. Soooooo, someone else told my boss that

My old company (CM) ran SMT to 50ppm including some very complex boards. We established the normalizer number by: #components + #solder joints. As was stated earlier, the ppm for any given product is the result of many factors. You may get differen
