IMHO, depending on whether its a regular run model, or a properly designed/setup pilot run model, getting a mean 75%-95% First Pass Yield (FPY%) is possible as a benchmark target. This is derived from your manufacturing history capabilities, and requ

i would say that you are there already. with 10,000 DPM0 you have a 1% fallout, you are at 99.9 basically. 1 out of a 1000 boards will fail? of course one thing we need to know is how many opportunitites do you count for a chip resistor for exam

Stability of process is what your measuring so lets not assume a stable process(if your process was perfect you would have no defects). With no test a medium complexity board will be around 68.7% (according to Consulogic). I dont have many other sour

Although the following is not true capability machine assesment I feel that monioring the process at screen print, placement, reflow and wave gives results for both design and process guys to asses thire process. The project has been running since Ma

Dave et al, I just print out and read a copy of the aforementioned recommended article. Mr. Mangin gives a clear picture of why DPMO is to be considered a more pure data than First Pass Yield (FPY). However, I must note that his interpretation of h

Is this revisionist history? Have you been breathing deeply, while eating corn doodles? Let me knock-down a couple of Zoloft. OK. Here�s the way I remember things � * UIC, Dynapert, and Amistar made the best PTH insertion equipment on the planet.
