MPM SP200 are nice. Visual alignment with cameras. Get the one with dual head if you want metal squeegees. We have produced boards with .020" fine pitch with very good results. Unfortunatly, MPM does not sell those anymore, so you have to hunt for a

The MPM SP200 was replaced by the model SPM around 1994. They also have the model UP100, which is from the SMTech purchase. The UP100 is the low-end MPM semi-automatic. Information on the SPM & UP100 can be found at http://www.cooksonee.com

i would look at an SPM from MPM(speedline) or an SP200 from Europlacer (speedprint not speedline) We have used both of these machines with great success from 16mil pitch qfps to .5mm pitch uBGAs.

Wayne, Sounds like a gasketing problem. When the horizontal apertures are bleeding but not the vertical apertures. Could be poor underside support, HASL miniscus issues, masking or plugging issues, but what many people do not account for is that t
