OK, so is anyone qualifying CGA's yet? Our first batch of CGA qualification is not going too well. We stuck with the teardrop shaped pad but the solder fillet is not as big as expected. What size pads is anyone using, i'm getting conflicting informat

Grind the point on a pogo pin from an in-circuit test fixture flat and push on a leg of the component till it bends, mark the deflection, then add about 30% to the length that the pin pushed in (maybe more if your using no clean and the residue adds

We had two of these machines. I have worked on many different types of equipment, and these machines were by far the most frustrating to work with. The calibration is a pain in the butt and it does not seem to do what it is supposed to. Also, the sof

This machine is a peace of crap; I work on this, before I went in the business for my self Later-on I got one for almost free. But I refused the offer because the fright charge was in my opinion more what the machine worth, now I had MYDATA TP9-UFP

Well we actually bought a used 3AV system. Been running with no problems at all for a while now. We also already had a 3Z system that has not fared so well. We have replaced both the Y motors, 3 of the 4 Z motors, belts, pulleys, PCB's, spindles...et

Questions: 1. Is this a retail product sold as PCB only? Or is this in a finished chassis / case (like an external modem)? 2. Are the customers damaging only the BGA devices? Like prying them up with a screw driver? What? You can dam and fill

http://www.mgchemicals.com/products/832.html Loctite makes a version too, if I recall. Designed to be tamper evident, but yes, rework is a bear. We had similar results using one of Lord Chemical's urethane potting compounds. It was a filled black fi

If you have a board that you've run several times, now you run it and like before all settings are the same, but now you have 0603's randomly skewed or an inch or so away from their intended pad (as if popped up in the air), or an occasional 7343 cap

Even when you run a board several times, the machine may not make the same travel path every time. This in itself does not create a problem, but the vacuum on the nozzles could be different, dependent on the configuration of components on the heads.
