I have seen this problem before. There is a cable that runs from the Quadalign board to the backside of the backplane. It is not secured in any way so it may have come loose in shipping. Open the right side panel on the machine. The Quadalign board

In regards to your panelized PCB it sounds like your step and repeat in you pnp program is slightly off, by 0.02mm from the sound of it. Are all of the components moving in the same direction as the fine pitched IC? I don't know what type of machin

David, Assuming your machine has a WHITE controler, not a SILVER controler, there is a floppy drive inside the front panel of the controler. (Remove the top cover to reach the 50pin cable.) If Tom offers you a disk to try in the machine, go ahead. T

We finally can't avoid adding wave solder to our process anymore. For lead-free, medium sized wave I'm leaning towards mid 2000s senju units as the best fit. I've never run their equipment. Opinions? As a point of reference for our general capabilit
