We are currently experiencing a high rate of false calls on our 0402 chips. Resistors for the most part. Has anybody out there found a setting where this false calls are minimized? We are using top red light, pattern inspection,color inspection ( wh

I am getting a lot of false calls on our AOI(YTV F1)on low contrast part markings like brown-on-yellow tantalum capacitors and etched oscillators, and on lead banks where the pcb has the part outlined in silkscreen. We are contract and cannot change

I read through this thread somewhat and checked out the pictures. I've programmed TH lead checks on a newer Yestech and an older Mirtec. I personally use the Yestech white-top/histogram check and the only solder inspection Mirtec has. In my experienc

You should also have a backup calibration file to reinstall. If its software related this would put everything back to spec. Mechanically I would call Mirtec as well to ask the best method so that you dont have to reteach all your boards.

Some AOI manufacturers require you to put in a GOLD PCB. Gold PCB is a perfectly manufactured board - Correct placements, correct polarity, no solder short, a "GOOD" PCB. With the vision limitations of some AOI equipment components that have variatio

Dominik, I have to agree with Andrew on his choice of Inspection Technology, but not the vendor. I looked at 2 of the 3 that you are asking about (TRI did not make my cut as I just didn't get a good feeling from them). I also looked at the Mirtec and

There is learning on all brands requiring fine tuning the test parameters. The first point is not to allow defects to escape. Many brands can do a good job with preventing escapes. The struggle with all the brands becomes false calls. The companies r

I have noticed this on some of our large multi-circuit panels. It's such a slight rise in our false call rate that I haven't really explored it. I'm just guessing that it has something to do with the fiducials calculating the twist/shrink of the boar
