We use a small surface mount connector that has two alignment pins to ensure proper alignment. It works fairly well. I'm thinking that this simple alignment solution might work well with lead less parts like a BGA or QFN. I can hand assemble QFNs

I'll chime in here as well. If you have adhesion problems, 90% of the time it's contamination on the substrate (soldermask, flux residues, cleaner residues, etc.). Like Dave said, omega meter is a test for gross cleanliness, and it's OK for process

I would suggest that the pad size vs lead length vs lead pitch are helping cause issue if rest of PCB is ok From DFM , yes reducing lead length - experiement or reducing pad diameter could help. Also flux can still be issue, try fluxing part prior

I would agree with Sr Tech..Grid lock and systems like this can be used on the Ekra, MPM and DEK printers also can be used in Pick and place depending on the density of pin. If you choose the method of printing out a 1:1 photoplot. Glue it to a piece

Yes, I have experience with table model of ScanSpection. Machine work fast, but process of job program making is very slowly. If you each time have elements from one supplier - this machine for you. But if you have many suppliers of components - it's
