First all, you must define the specific defects that you wanted to screen out by your AOI system based on its capability, so you can allocate the undetected defects on your other means of inspection methodology. Then optimize your AOI inspection para

That's hard to quantify. I deal with escapes when they occur, but I haven't kept track of that data. It doesn't happen to often. But when it does, I take it back to the AOI to analyze why it escaped, and change the algorithm to catch it, if I can.

Most AOI discussion should include assessment of escapes and programming time.

I have been using ICT for a number of years. It is still a viable resource for catching defects in the production process. AOI doesn't catch everything, such as bridging on QFN or J-lead devices (this will depend on the type of AOI and camera syste

We have filed returned (approx. 5%) of the boards that exhibit inner layer short @ a particular connector locations. X-section revealed there exhibit Cu residue, but aside from that, we also suspect there could be organic contaminant, what test shou

Thomas, We evaluated several AOI machines and narrowed the field to two, YESTech and MIRTEC. We had an opportunity to work with both of these machines on our production floor. In our experience, the MIRTEC machine simply outperformed the competitive

With AOI it really depends on what you are testing. Not only what criteria, but what different types of components. We run a high volume low mix application for automotive checking for presense, positional accuracy, and all solder joints. We curre

Hello Carl, Thank you for your comment Obviously, we are evolving and debugging our test to get the best results ("no escapes no false calls") :) and using a combination of 3D and 2D tests. With the previous AOI, we had a much higher false call rate,

Hello, I have seen two different ways in two companies - one they do it before start of every batch, the others do it when a program is made. I am a fan of the first one, but it depends on company policy. Its good when you have to make a lot of chang

Good Day Michelle, If you are looking for a solid AOI system that is simple to program and extremely accurate my recommendation is MIRTEC by far. We checked out several machines and narrowed the selection down to two, YESTech and MIRTEC. We had an
