#103232 - Something like this?
Responding to: Steve M. Taylor's previous message
Steve M. Taylor said:
You can make a very very cheap bubble etching tank from a polythene container (long narrow tanks are best), a piece of plastic tube and an aquarium pump, or even, in extremis an inner tube filled with air. Drill or pierce SMALL holes in the tube for a length comparable to the length of your tank. Weight the tube, so it sinks even when full of air. Place the PCB VERTICALLY in the tank and fill with etchant- we did it with a rail across the tank and some clothes pegs to hold the pcb off the rail.


Hi Steve, is it like this you were mentioning?
