Ed,

We had a couple of fancy bottom drills when I worked at Fortin.  We
spot-faced down to the inner layer targets then used these drills made in
Switzerland to drill the center of the target.  The customer used that for
set up tooling and could drill with these.

I want to say the manufacturer was Posalux.

[TN] Bombsite PCB drill
Sent by:

Hi fellow 'netters,

I took a job up here in the Silicon Valley. I've been lurking, but not
participating much. I must say, it's good to be back!

I've been looking for an old school pcb drill, bottom up configuration
with a magnified bombsite optical alignment, typically was used for
homebrewed prototypes.

I've scoured the www and cannot find a current manufacturer.

If you might have one (or know where one is) I'm very interested.

Any help would be appreciated!


Regards,

Ed Popielarski
