Hi Paul!

We almost did a heavy copper board for one of our customers, but their
customer got nervous, and they decided to keep the laminated buss they were already
using.

In anticipation of possibly using a heavy copper board, I talked with with
Robert, and bought his books. One shop that Robert turned me on to was UPE in
Canada (http://www.upe-inc.com). I spoke with a gentleman named John Vandersleam
(613) 257-7569. He sent me out a package with a UPE brochure and a sample PCB
with some heavy copper plating...and I do mean HEAVY! There's samples of 10,
20, 30, and 40-oz copper on the board!

I was just blown away when I saw that PCB!!!
