Laser etched PCB

My friend drew showing off his laser etched circuit board!

step one: spray paint copper clad circuit board

step two: etch off spray paint (where you DO NOT want copper)

step three: etch circuit board (using etchant of choice)

step four: use paint thinner to remove remaining paint!
