SPC for each assembly(I use C(for board defects)NP(for unit defects) at the end of reflow to determine process capabilities determine Control limits. Once control limits are set, inspectors stop the process until out of control limit is addressed and

Wondering if there any CP7/F4G programmers out there that can help me out with this one. I'm assuming the setting for max and min nozzle in the "environment" section of the part data would allow me to use either the specified max OR min nozzle in th

If the CP7 is like the CP643, it defaults to the MAX size unless that nozzle is skipped. Then it would switch to the next smaller nozzle on that head.

Two ways at it.You could just put the same nozzle for both the min and max.Or you could move the feeder into a location that has similar parts using the nozzle you want. With the feeder setup it should be optimized for the least amount of nozzle ch

Ask your compadres how you can control a process when it's output has already been completed? If you do second side assembly before you inspect the first side, you can't possibly apply real time corrective action. I know what I'm talking about in t

Dear all, What are your views on reworking BGA's? I mean, with the BGA going through reflow temperatures four times or more, and with a manual reballing process, wouldn't it raise up a few reliability issues? Would you consider not doing rework on
