Can someone give me DPMO numbers that are considered "world class" (if there is such a number) for... a)solder joints b)placement I appreciate any input that will get me closer to a number that will appease the bosses AND be realistic.

Paul- Start with apples to apples comparison. What world class product are you building that would benefit from a benchmark comparison? Other than that, if you are just starting then crunch the numbers, find the highest values, do continuous improvem

...reasonable benchmark. 30 to 100DPMO is considered world class. All else? Well lets just call it "not-so-world-class". :) Dean

Look at "DPMO: A Tool For Achieving World-Class Process Quality" Charles-Henri Mangin, SMT magazine, 8/00, p 77-78

Thanks Russ and John, To clarify defects when manufacturing a PCBA, I use (2) groups of defect categories, one for components and one for solder joints. These can be calculated separately or combined A component defect could be: Missing, Miss-alig

| Does any have any reports on competive Component PPM levels for world class manufacturers ?? I would also like to get any information on the fault spectrum for component mounting. | | Generally, it is accepted that world class is below 100 DPMO (

I have been using overall combined DPMO of SMT PCBAs as a performance metric. All defects are recorded down to component location and defect category. The resultant defect data table is analyzed with detailed pivot tables, defect type and defect loca

Thanks for the responses, and I tend to agree. I would much rather go through a more structured continuous improvment process (set goals, meet them, set new goals and so on). Our company is rather small and made the jump from all through hole to mi

We use a fairly simple system. IPC put out standards 7912A and 9261A to define opportunities. Basicly the "number of components" + "number of solder joints" = "number of opportunities." Some six sigma benchmarking studies indicated "Sigma Level" =

I've run up against the same problem that I know many of us in the industry face; our management wants to obtain a "world class" level of production. This has come up before, and I've looked through several responses dealing with ppm (dpmo), failure
