Hi Tom, Thank you for your comment 75% FPY is also our target, cause we gonna have the AOIs in the SMT line. So you would expect more opportunities? I didn´t notice but there are not so many components with high opportunity rate. (the average numbe

I am testing some BGA's (PBGA 30mm x 30mm) to evaluate the maximum ramp rate we can achieve in our reflow oven. Temperature is being measured at the body(top) of the component / not leads. After several trials (with various oven settings), the high

My old company (CM) ran SMT to 50ppm including some very complex boards. We established the normalizer number by: #components + #solder joints. As was stated earlier, the ppm for any given product is the result of many factors. You may get differen

O.K., folks, I know this is a loaded question, but I've been asked to find the answer, sooooo: What is an acceptable defect rate in ppm for a surface mount process, assuming that each component has the potential for one defect. This would include de

The Fuji CP6 and QP242 should be more than capable of placing 0402(cp6) and bga components (QP242). You must be having some programming difficulties.

Hi Anthony, Hopefully some of the following may help: 1) Electrics - do you know the rating of each machine and the total load, and can your distribution box take it? Do you have the correct cabling and connectors in place to just plug the machines
