Video shows how I build a PCB for LED. Painting the circuit path with my cnc-milling machine. Drilling holes and cut the small PCB´s with a 1mm cutter. Etching the PCB in 50C hot sodium per sulfate. The etching mashine is diy. Heater and air pump is bought for using in a fish tank. I opened the heater and changed the max temperature.

how long does it take to etch with the sodium persuflate? is it faster than feric clorhide?
