I am considering getting a small drill press for electronics
repair...what suggestions does the group have?
Thanks

So I take it that no one has a Servo drill press to work on
circuit
boards?
TMT
Exactly what (repair?) work would you want to do on circuit boards,
that
would require such a tool ...?
Arfa
To access circuits within a multilayer circuit board.

This thread might hold some interest if you'd quit playing 20
questions.
Why not paint a complete picture for us? What, for example, do you mean
by "access?" To what end? How might a drill press assist in that
endeavor? You've asked for recommendations for a tool, but it's
difficult to offer those recommendations with any validity if you don't
tell us what the hell you're doing, or plan to do. I'm going to keep an
open mind, pending some actual information from you, but so far I'm not
envisioning a drill press as a very useful tool for PCB surgery.- Hide

Based on your response it sounds like you have little on hands
electronics experience...drill presses are used in electronics
development and repair.
I asked for what others have for a drill press which used for
electronics work.
Thank you for your response.

Little hands on experience? Well, in repair, that's true. In electronics
manufacturing, I've got 22 years as production manager of a job shop.
Across the hall is a full machine shop including toolroom lathes and
mills, CNC equipment, machining centers, and turning centers.
I've put together a few million PCBAs, and I'll wager I've personally
hand soldered a few hundred thousand solder joints. I've never run into
any need to use a drill press in PCB work, save maybe making a
rudimentary prototype board, and for that I'd use a CNC mill, anyway.
Since you've been nothing but coy about your reason for inquiring, I'd
call that playing 20 questions. You have YET to tell us WHY you want a
drill press. Saying it's for "development and repair" is completely
meaningless. Cut into a multilayer board with a *drill press* in order
to make ECOs to the circuit? Have fun with that.
Ne' mind Smitty. We all still love ya ! For what it's worth, I have been
directly involved, right down at floor level, with electronic REPAIR for
over 37 years now, working on a huge variety of equipment from full-blown
industrial to general domestic, and in all that time, I have never had to go
down to break an internal layer of a board to effect an ECO. That's not to
say that I haven't *seen* it done. I used to work with some computer
graphics equipment that employed, as I recall, 6-layer boards, but it might
even have been 8, now I think back. Some prototypes or early development
versions of boards had occasionally had this done to them at the factory,
but such problems were quickly corrected in the design. If you had to do
enough of them that it involved having to have your own equipment for doing
it at a repair, rather than factory level, I don't think that it says much
for the design of the board, or of the ability of the designers and PCB
manufacturers to rapidly correct any such problems of design, 'on the fly'.
If you are figuring on having to do touchy delicate work like this on a
regular basis, I hope that your clients have deep wallets to be able to pay
you what you will need to charge to make a living at it ...
