Homebrew PCBs

An aquarium air pump also works as a vacuum pump.  It pulls a higher vacuum than a shop vac, quieter, and more convenient.  I use one for photoresist vacuum bagging in a 12” x 12” bag and I would recommend it over a shop vac.

You really want to use a shop vac for that kind of work! Shop vacs have separate fans to keep the motor cooled while it's running - household vacs don't; they rely on the air flow thru the hose for motor cooling.

 

Adhesive squeeze out shouldn't be much of a problem with a polyethylene bag; they're almost impossible to glue anything to.
