The standard method to repair intermittents is to alternately heat up and cool
down the circuit.   Heating is easy using a soldering iron or heat gun.
However, the can of "freeze" stuff I had contained freon.  Since it is now
positively known that freon destroys the ozone layer what chemical or process
can I use to cool a PC board down.
Does anyone have any ideas or know of non-freon based "freeze"?
