Just bought a used machine and everything was working fine and now the camera will not initialize. Powered down completely and rebooted, same thing. I powered down again moved camera to center of axis, it moves to the lower right hand corner which I

I have identified a Board design issue and having trouble convincing others of my findings. I have a BGA (Sn63 balls, +1500 IO, 0.6mm ball, 1mm pitch, with heat spreader plate)that has a high incidence of solder shorting on the corners. The board i

Hello guys, I need your thoughts on this PCB I have, it seems that It was damaged by hit or something, I think there is no big issue because damage is on the corners, but I'm not pretty sure if It could has some other hidden damages, It has few SMDs

Hi, Regarding to thermocouple placement, you should use a precision thin drill. Drill through the bottom of the board to the top as follows: One hole in the center of the part, preferably into one of the center balls, if available. One hole into the

Hi, If your PCB is large, you waste a time. Any picture, you takes, will be with corner distortion. I suggest you to: 1. use AOI (manually or automatically) 2. try simulation of your PCB production before real SMT production process 3. use human FAI

I came into work this morning to an error on one of my printers. After powering on machine, the error MACHINE DOWN popped up in the top left corner of the screen. I have the giant manual and could not locate a solution for this error. I have checked

So what your telling me is kind of vague. Does the machine home and go to the front left corner of the machine? If it does....this could be a quad align problem....meaning dirt on the lens or so-forth. You should watch the heads homing in the z-axi

We are using a connector on an assy whereby every now and again its raising up on one corner, we have been advised we should weigh them down to ensure flatness, this is the 1st time I've come across having to weigh anything down at SMT reflow? Any ad

yep, Phil nailed it. Also, don't put them in all 4 corners, or if you do, don't place them symmetrically. And keep them far enough from the edge that rail clamps won't block them. And make sure to put them on BOTH sides of a double sided board. Th

Two Fiducials are sufficient for alignment. A third fiducial is useful to make sure the board isn't loaded backward. This assumes there's not a fourth fid on the opposite corner of the third. More than three fids just wastes time on a printer since
