Guys, What are the best effective tests methods to show capability and repeatability of reflow ovens and AOI machines?

For the ovens you run the profiler and you compare graphs. For the AOI you should run these golden boards(boards that you keep for AOI test - might have intentionally implemented defects) once in a while and make sure you are getting the same results

As always, our good colleague Evtimov is right about the AOI and oven. For the AOI you need to make a golden sample board(panel) and test if your machine can catch all defects that you simulated BEFORE the oven. Try to me as accurate to real defects

Hi, I think the standard was IPC 6850. But I will recommend to go directly with the sigma test. Place parts with the machine and measure the placement accuracy on another machine. 4-5sigma at 50um should be a good machine. If they have sigma in thei

Work as a consultant and I have a project to research the pros and cons of automated optical inspection (aoi). Would like to get names of vendors, has any one done any Beta testing of these machines. Are they reliable? Would appreciate information
