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 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,
