How to inflict ESD damage on a board?
My go to method is my ghetto ESD-gun (a cheap electronic lighter) ala - Long neck lighter Split it open, strip the wires and zap away :) It should produce a few kilo volts.
Scotch tape being peeled was being investigated for defribillators. They also produce xrays when peeled in a vacuum apparently.
Dry room + carpeting
Find a room where you walk across the carpet and touch a doorknob and get a little zap. Bring your board to that room and repeat using the board instead of the doorknob.
