Re: Alberta Printed Circuits drill rack warning

I use AP circuits all the time. You do really need to be aware of the
"standard" drill buts that are used because you are right. If you use a lot
of extra bits not on their list the price goes up quickly.
You also have to read their instructions. They require the hole sizes to be
.003 fro plating. So you don't give the final sizes but the D+.003 value in
the drill racks.
However, with this in mind, I still like their 3 day service.
