Brendan, Unfortunately, I no longer have MYData equipment in my shop (I moved to a new company), so, I can't help with finding part numbers. I do know that you can buy the motor/counter units separately on the open market..and, I think you can buy

We have several selective soldering machines, that because of several minutes of process time per PCB, one operator can keep 2 or sometimes 3 machines loaded and running. Other days only 1 machine is running but operator does not have enough time to

A couple more things. The PCB. What size are the pads? One time a board shop had difficulty putting masking between the pads of a QFP and the pads suffered as a result. When I told them they didn't have to have masking between the pads, the pads w
