DIY PCB etching

[Harry Bissell]

Hi Theo...

I've found that conductive opjects that are encased in microwave absorbers are
OK...
such as metal underwater (under etchant...)
It seems as long as there is a good absorbive load for the RF you are OK...

Etchant in a microwave is a bad idea for ...

Fumes can corrode the oven itself...

Contamination (possible) of foods you put in the micro later...

I use the waterbath method myself...
