RE: [CAD_CAM_EDM_DRO] automated "labjack"

Any chance of a photo Bob.

I've seen big expensive machines, and selective ones, all quite expensive
for various reasons.

Haven't seen anything like you describe.



Thanks Mark

Archie,

The one that I have seen moves the boards along on a carrier through the

It is my understanding that when boards were soldered commercially the
boards were stationary and a wave was created that deposited the solder
on the boards. But what do I know.
