Are your pads on the board aligned correctly? I've seen this a lot lately. Pads on opposite sides are not aligned correctly. This causes the part to twist. If you have the Gerber and a way to check it, it's worth the 3 minutes to check.

Has anyone had any success with placing BGAs with the Quad QSP-2? We have been having alignment issues with BGA placement but our placement of 0402 parts is dead on. We have worked through the calibration and it seems to be correct.

We are having continual QuadAlign issues with a 1997 vintage QSP2. Every part on the machine has been replaced� now they want to replace the entire head on gantry one. Does anyone have any experience in this area? Sincerely, Andy Micro Air, Inc.

Check the fuses on the quad align card. There are 2 on each card. They are surface mount type. Typically one of these have blown. Good luck

My QSP2 motors keep shutting off with an error message on the screen that says Z1 motion fail. Z safe motion motion failed due to previous error. When homing the heads I observe the servo amp indicator LEDs. They are all green while the gantries are

I have a QSP-2 which I assume is in the same family as the QSA-30. I compared the diagram that is in the service manual with a board from a 2-C and they appear to be the same. Your best bet would be to contact PPM at http://www.goppm.com. They shoul

Those cards are all different. The c-series stands alone by itself while a qsp2 and qsa-30 mount into a slot. They were all manufactured seperately for each machine. I would purchase a new refurbished one for the 2c machine and forget about the other
