My first choice would have been to use the "mini-wave" but couldn't because of clearance. I heat the board in an oven to 250 degF. grab it with welding gloves and run to my soldering iron. Not the most precise process but it works. Fortunatly I don't have to do very many of them.

Hi Charles! We have a power supply assembly which is 0.90 thick and
contains 18 total ozs. of copper - that exceeds the limits of hand
soldering but we have been able to "mini-wave solder" it just fine. I can
just imagine that 12 layers of 4 oz. would be equally difficult. What
processes to you use to process a 12 layers of 4 oz. assembly?

Ok Steve, I'll bite! What type of application utilizes 6 oz. copper layers?
I have visions of trying to solder to a "bar" of copper if the resulting
printed wiring board had 4-6 layers of 6 oz. copper!

Mornin' all!
Anybody know of any Fab shops that are UL certified
to do 6-oz copper? We work with some that are certified
to do 5-oz, but not 6-oz.
One of our customers is requesting this from us...
Thanks!!
