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 ( which we sometimes mask )and anchor on the marking as well.

Thanks in advance for your input!

Dback, Some questions for you: 1. Are you using the red light configuration for better contrast on the 0402 parts? 2. Is your system fitted with both low and High Magnification cameras?

Have you spoken with the guys at YESTech? Their phone support is outstanding and their AE’s are among the best in the industry.

Dback,

Most likely shouldn't have color inspection on. Using red light colors will look the same so you gain nothing by using this.

What exactly are you getting as false calls? Sounds like you have lots of things going on in this type of inspection that might not be needed.

I was thinking the same thing. Try turning off your anchors and look at the size of your search and % match you have set. if you are concerned about not catching missing components, try training a negative template.
