A couple ideas are: * Search the fine SMTnet Archives. Use search terms such as: ppm or dpmo or *7912 or *9261 * Bob Willis runs a PPM Monitoring project that compiles data from industry. Look here: http://www.bobwillis.co.uk/ppm/asp/Monthly.asp

We have no relationship, nor receive benefit from the company referenced above.

for reject rate depends on various parameters, Part data parameters, (Body tolerance,Part pickup & transport speed etc. ) Also depend on vaccum level, ( During the PM we need to messure pickup nozzle vaccumlevel using manometer ) According to raw material supply venders we need to veryfy part data Some small chips (0402,0201 etc;) are face to magnetizing effect in component pickup nozzles, (Mainly in steel fabricated nozzles)
