PCB Etching Agitator
Posted April 8, 2013 by Chris
“I have tried two different types of etching for PCBs: the bubble tank and the shallow dish method….The shallow dish method involves finding a small shallow dish and filling it with just enough etchant to cover the board. I measure out about 250ml each time. To etch, the tray is placed in a tub of hot water and agitated back and forward, while I inhale the fumes from the tank. Eek! Hence the need for a mechanical solution.”
