Is there an industry standard in calculating SMT process PPM level for benchmarking purpose ? What are the industry benchmark ppm number for some of the defects like solder short for 20-mil QFP, tomstone problem for 0603 components etc....

Hi: I am doing a research to compare the a new high resolution digital color inspection system with other technologies in the market. May someone give me a feedback about which equipment and technology is the best?. Thanks

David, I can say this we have 2 vision systems Orbotech and Omron. Both working OK but there is a problem with both....They find a solderballs in board and there is no solderballs! Otherwise can not tell what is a best system. Regards, MadReind

I am not a fan of "Gold Board" type of inspection. There are many new sophisticated ways of inspection one being neural networking. This is a method where learning occurs by exposure to a truthed set of inputs and outputs data where the algorythim in

Agilent has a great article on determining whether automated optical inspection (AOI) or automated x-ray inspection (AXI) is right for you. It's a PDF file that can found here: http://www.ate.agilent.com/EMT/LIBRARY/X-RAY/DOCS/59883661en.pdf To sum

When evaluating AOI you must first define what type of inspections you want the system to perform, pre-solder or post-solder. What separates many mfgs. of these systems is how effective they are at finding post solder defects. This is where camera re
