Homebrew PCBs

A good test of this theory would be a blank cd in a (glass) pan of water.
 
Normally, CD's aluminum layer will melt within 5 seconds in an active
microwave.
I use this method to distroy CD's with confidental information

Subject: [Homebrew_PCBs] Potentially stupid or brilliant idea



I know that placing metal in a microwave can produce "interesting" results.
However is there any experience with a piece of copper in a cup of water?
I'm speculating that the water may keep the copper from being the primary
load on the microwave and also provide a cooling surface for the copper.

Just interested in heating a persulfate etching solution.

tnx
