I am assuming you are initializing each motor individually through the service program. The z motor theta is hard to see so I put a mark on it with a colored marker so you can watch if the midas tool nozzle is actually turning or not. You should be a

I am about to order a stencil and I can already see that I'm going to have issues. I'm hoping someone has a recipe for this scenario that we haven't tried yet. The parts are 16 mil pitch bga's, the pads are NSMD (10 mil dia. with 12.6 mil mask open

Hi George, bad luck! That�s why we professionals get so much money for it. Those "thingies" are mainly capacitors or resistors. If a capacitor is missing you might with luck not even notice it. A resistor, that�s different, you will notice it, what

Gawd. Sure FR-4 will meet those conditions. Tg [check the fine SMTnet Archives for discussion on Tg] of FR-4 is 130�F or so. Consider: * Is the delT between Tg and the upper operating [or storage] temperature acceptable for your application? * D
