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.

I have heard the following from various sources (that I believe) that apply to volume manufacturers as of late last year: dpmo with BGAs- 300 dpmo with .020" pitch- 75 dpmo with 0402s and .020" pitch- 40 Our lines run around 90-200, but have some p

Just on the basis of initiating a DPMO measurement system, can anyone point me in the right direction as to web sites/articles etc. TIA Moss

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

I'm curious if you take specific actions based on the results of your DPMO.

Has anyone been using the following documents for DPMO and any feedback on them? IPC-7912 - Calculation of DPMO & Manufacturing Indices for Printed Board Assemblies IPC-9261 (In-Process DPMO Estimated Yield for PWA) Also is there any databases rea

We are using a glue and wave solder process for primarily chip components. Our products do not use any fine pitch components. What would an acceptable benchmark for the placement defect rate be? 50 DPMO? 100 DPMO? 200 DPMO? Thanks in advance,

Consider what you are trying to assess. Any product with one or more defects will cost you money. Your supplier should be using: 9261 - In-Process DPMO and Estimated Yield for Printed Board Assemblies You should be using: 7912 - Calculation of DPM

It has been mentioned that DPMO offers large advantages over First Pass yield calculations for measuring process performance!!regarding the same I have a few queries: What are the benchmarks for using DPMO as measures of process performance? How is
