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.
