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? Picture Courtesy:Don McTavish(see this link for some 'unforeseen' etching tanks! I liked the speaker system!!) Cheers, Vignesh |
