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

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

Excuse me seeming to parrot Wolfgang�s posting, but he makes good points and I'd like to expand on them. I disagree that it's about disliking a "non-techie to post a reply/comment to the SMTNet forums." It's not about WHO posts. It's about WHAT i

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

Your Ionograph and Zero-ion Values are set by you. There is no raw pass of fail criteria only the limits you set up. Ionograph is great for bare board resistivity (salt) test just as a pass fail for incoming inspection but this is all per your facto

Richard, With respect to the Resistivity of Solvent Extract (ROSE) test, the test solution is exceptionally aggressive. With the Zero-Ion for example, the test solution�s resistivity is 150 M-Ohms. Additionally, because test solution is made up of
