Greetings guru's,
I have an inquiry into hole location tolerance, especially directed to our
many PCB manufacturers listening in.

What is the best reasonable tolerance you can expect, world wide,
(overseas as well as domestic suppliers), for positional location of
plated and unplated holes, without adding addition cost to the circuit
board?

Expressed in a true position format, would a diameter of 3 mils. be
unreasonable?  dia. .005?

Assume a moderate volume of production.

Thank you in advance.
