Possibly, yeah. Or the wrong sized nozzle ( or chipped or blocked ) We have problems occasionally with larger components and vacuum levels. If the component has a makers 'circular void' on the pick up surface then the actual pick coordinates have to

2, I have to scroll down to the bottom to see the image... and the outline of the legs isn't very clear. The legs are sort of blurred together. I had tried lowering the CCD offset in the part definition to -50, but it still looked bad. Could this

dave, you are right on. a blow torch isn't needed to light a fire. a small coplanar aluminum block works extremely well. my dept fixes thousands of fine pitch parts to to less than 4 mils from low lead to high lead every month. all we use is a sm

I have been working with GSMs since 1999. Mostly, I've been programming them but for the past 2 1/2 years or so I've also gotten to know them mechanically. I think they are great machines. If you are looking at Flex head GSMs (4-spindle) they won'

We've been using fids as badmarks on panelized boards, with reverse recognition so that an uncovered fiducial is a good mark. It's worked fine with 1.5mm fiducials but now we've run into problems with a board with 1mm fids and we can NOT get it to wo

If you are buying this tooling, you need to ask yourself if you really need the OEM tooling. While it is definately required for come delicate and complex connectors, for a machine like the 6T, 95% of the time you can get away with a metal block. y
