We currently have an AOI after reflow, and I was wondering how others have thier line setup? Does the AOI operator have to get up and get a board from the oven to run, or should the SMT operator hand the AOI operator a board. The AOI operator does

It sounds as if you have your AOI set up off-line, and you're "AOIing" a sampling of the PCBs produced. If that’s the case, then the responsibility of who drives the inspection really depends on how you configure it. If it's based on the number of P

I have to agree with you. We do go by piece rate not by time. Also who is supposed to make a process, the Man.Eng., or the lead? I would think the Man. Eng and the lead should make sure everyone is following it?

What is changing the marking on the part? * Is flux residue coating the part to change the the way light reflects from the part surface? [Run a board with tape on the part, then remove the tape prior to AOI] * Is the heat of the oven changing the mar

Thank you for kindness advice. From the result of IC after pass the reflow process. The color of letter will change to similar color of material compound of IC. Then when we inspection by AOI machine, we have many problem about high fault reject rate

Every time to create new AOI program we must manual set at bright lighting level for each component. then this case we think the parameter of AOI setting it not concern for this problem due to the golden board that we use to confirm machine before st

I have problemabout fault reject rate at AOI very high, due to inspection letter or marking on IC body. It have uncleary. When I check at raw mat'l of IC it no problem but after pass reflow process it show marking not clear ( Laser marking type). Ple

On our machine we have found that some IC's require a different light for inspection based on the manufacturer. Have you tried other lighting options? You may need to talk to the AOI manufacturer to see if there is something the machine may be able

So your golden board isn't a valid representation of your production material. I don't use AOI but it sounds like either you need a vendor that can guarantee the same part marking appearance as you originally programmed to (not likely) or you need a

Our AOI machine can save various views of the same part number since we all know that different manufacturers will mark parts differently, some manufacturers vary their own marks. We get parts from the same manufacturer but different date codes that
