Hi Ryan -
One idea that I have seen work is to install a set of copper tubes
that you run chilled water through and using a standard fan to
transfer the cool air to the assembly. This idea assumes you have
chilled water present, you have room to incorporate the system in the
wave solder machine, and don't find an off-the-self system that meets
your liking. The main danger to avoid is blowing air so hard that you
disturb the solder joints while they are still molten. Good Luck.

Does anyone have any information on what type of fan (ionizer) works
best at the end of the wave solder machine?
We are having some problem with cold solder joints on some of the
products with large ground planes. They are taking too long to cool. I
was going to place an ionizer that will blow onto the bottom of the
board as it leaves the wave solder machine. We are running an
Electrovert 2000/s.
Also does anyone have any information or experience with how far away
from the wave itself the fan should be placed?
Any help is appreciated.
