Like other things, the more you pay, the better the gage. I'm not sure which Cyberoptics unit you're considering, but LSM has a lousy gage [R&R ~25%]. We use a microscope with lousy gage that costs waaay less than some laser guided thing. Search t

Hello Doug, There is no tuning up of the cyber-unit. From the symptoms you describe......sounds like the white cable that plugs into the cyber is intermittent. Maybe you can find one somewhere and try that. The cyber unit is a closed assy. and was ma

Your firmware is so old that the problem is not in the mod codes anyways. You have a problem with the cyberoptics head. If its not working at all, i would remove the lens assy on the front side where the cable plugs in and blow out the unit. Maybe if

Thanks Sarason, Laser alignment of components was actually our first attempt - it certainly offers speed and accuracy, but purchasing cyberoptics units would blow the budget & getting round their patent not really an option. I've seen the Essemtec

I have found a consistency in certain package types which hold a very close tolerance. We use a six mil laser with electropolish. BGA's are tight. Some IC's drift. I think the range and Cp is more important than the Cpk for today. The reason bei

We have two QUAD 4C working in tandem. 3 months ago the EPCU battery (QUAD # 2) died, then we change it. Then downloaded the MODs from the controller to the assembler(does simultaneously on both machines). All this time we continue to work normally.

Chrissie, I'm glad you (and your people) made it through the painful process of reworking all those BGA's. Hope all your boards sucessfully pass test. Now on to the larger issue. In my experience, the solder paste screen printing process is (along

Hi Mark, There are many tools available for measuring solder paste height. Most machines use laser as the basis for inspection while others use structured white light. If simple height and width inspection is all that is required, you can look int

Hello Bobpan, Thanks for the response. 1. Function 30 gives me a consistent 182-185, even after nozzle changes. I can vary this by changing mod code 15 and I have been advised to aim for 90-110, but it doesn't seem to make any difference so I've go
