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

In-Circuit test, or ICT, is the most common method of electrical test for an assembled PCB. It is the most comprehensive and accurate method to ensure that both the PWB and components are working to specification. Not all components however can be el

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
