Do a search here for SMEMA standards, I had problems a while back and had to swap some wires on an OEM's machine to get it to interface correctly to our equipment. Probably not the same problem as your having but I did write a long winded explinatio

It depends on who's in the office. If someone's in here then I'm the one who works, but if nobody's in here then I just sit at the desk.

looks like my knowldge preceeds me again. I woud try a different flux. If it doesn't work - it will take a question mark away and your one step closer to total success.

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.

Yes we are. They are considered the Cadillacs of spot solder - so they better work. But yes, we have never had a repeatability problem in 5 years.

I am printing on DEKs and using simulara paramateres as for a solder it works really fine. In general going faster gives you more paste/glue. Less pressure gives you more paste/glue again. All the rest depends on your current board. Regards, Emil

Yes I agree with Emil that the Jig/Fixture design is crucial for alignment. The hot-bar machine I worked with came with a digital camera and monitor to aid with alignment. Other than that, the right profile (heat, pressure and dwell), and a good fl

I bought a geiger meter and put it together myself, it works just fine. You can buy it assembled for $305.00, or buy the kit for $195.00. Check it out here: http://www.geigercounters.com/Monitor4.htm

I did not tried this before (never hada chance to do it) but I considered such option - maybe try using temporary wavesolder mask on such small components. Run both sides of PCB through SMT oven and then mask 0402 completely and go with wavesoldering
