We are running an older GSM1 machine (sw.runs on OS/2) and I would appreciate any hints which vision algorithm to use for best results with QFN and similar parts. One of the ULC's is 2.6mil/pixel.

I think you can go with PLCC and j lead type. If not go with UIC C type. Both should work Regards, Emil

We run a bunch of .5mm qfn on a GSM1 with a 2.6mil camera, from 16 pad to 100 pad. Works like a charm. We call them a PLCC.
