How About Drying PCBs After Ultrasonic Cleaning
I recently purchased an ultrasonic cleaner and have been using it to clean flux and other nasties off of PCBs after assembly. I've noticed that some people recommend drying off PCBs with a hot air blower after they have been cleaned, since the ultrasonic cleaning can move water under components and into other hard-to-reach spots. I had the idea to use a food dehydrator to dry out PCBs after cleaning, but thought I should ask around to see if it is a good idea first. The food dehydrator I have is made of plastic, and I'm wondering if it creates a statically charged environment that might be bad for the PCBs when it's running. If this might be the case, does anyone have recommendations on what to do to try to dissipate static charge from the airflow? I could create some kind of wire mesh with a grounding wire, but I'm not sure if it would be effective or necessary. Looking forward to hearing your thoughts!

Much better is a blast of compressed air. You want to blow away the dirty water that is under the components, not let it dry slowly in place, leaving contaminants under the parts. This probably only matters in high voltage or high impedance circuits.
