| I am interested in locating PCB market statistics. Does anyone have any suggestions for locating this type of information (i.e. how many of what type of PCB machines were imported into the US last year, etc.)

Hi ChrisX, DPMO = number of defects per million opportunities. PPM (parts per million) is exactly the same, although the terminology is less clear about what it means. SPC(statistical process control) is a methodology based on statistical technique

I believe that this is discussed in such documents as MIL STD 105, or other statistical sampling plan specifications. Russ

Hello Dave, First you must make sure your measurement system is calibrated for accuracy, repeatability and reproducibility. We perform a standard GR&R Study on our CmController system on a regular basis to ensure that the system itself is capable to

Process capability indices are pretty well documented. Consider: 1 A good general SPC book like: Statistical Quality Control; EL Grant & RS Leavenworth; Mcgraw-Hill; ISBN 0078443547 2 Other good books are: Statistical Process Control For SMT; WS

Does any one experienced problems on BGA voids related to height of chip (placement), and also another question, Does any one has some statistical process control for the BGA soldering process? if the answer is yes, I'd like to have advice from you.
