Steve,
My approach on a board like this might include the use of a water based
water soluble flux like, HF-1189A. This way you can preheat your board in
an oven prior to wave then still apply flux without vaporizing it.
It'll be interesting to see how you handled these monsters. Keep us
posted. Good luck.

[TN] Heavy PCB Copper Wave Soldering...
Hi Ya'll!!
I just thought I'd share what is going to make things a little
more interesting for me here at work over the next couple
of days...
Go to: http://www.stevezeva.homestead.com<http://www.stevezeva.homestead.com/> and look at;
"Heavy Metal", Heavy Metal 2, and Heavy Metal 3. This
an assembly that I will be wave soldering, that has two 20-ounce
layers of copper on layers 2 and 11 (this is a 12-layer board).
I may be asking for some help for this...
My first try is to preheat and bake the assembly in a oven close
to the wave solder machine at 150 C., and then quickly remove
it from the oven, get it into the wave as soon as I can before it has
a chance to cool down, and see what kind of barrel fill I get.
I'll let you all know if this works, or I may be asking for some
help...
Kind regards,
