Switched out the mech. relay on the board loader, no change. Same behavior. Could not find a mech. relay on the printer... SMEMA wiring appears go directly to a PCB. And it is at that point that I run out of talent. If the machine weren't dedicate

Certain customers do give us CAD. USUALLY ODB++ but I've also gotten .ipc and .pcb . Many of our customers bought or inherited a design, and therefore have no control to generate additional files. Or, as you mentioned, they had another manufacture

We use both labels and lasers to mark our boards. Since implementing the lasers, the downtime attributed to bar code labels on those lines have dropped to virtually nothing. We still have problems with the labels wrinkling during reflow making read
