Build Your Own PCB Bubble Tank!

Instructions on how to build your very own bubble tank for etching all those homebrew PCB's you have always wanted to make!

The first thing you should do is get a plastic box of some description for your tank, then a heater for it, then something to use as a rack... its crucial that everything that goes in this is non-metallic by the way... lastly you need an air pump.

The heater and the pump Im using was salvaged from an old fishtank...

Ok, I used two cocktail stirrers as my rack... I melted the ends of the stirrers to form a kinda V shape for holding the board, I cut two holes for the rack and one bigger one for the heater. This will allow us to mount the equipment in the lid...

The last step is to run some hose from your pump down through the lid and across the bottom, ensure the hose at the bottom of your tank is perforated and the end is sealed, this will create pressure in the tube forcing the air out through the perforations causing bubbles!

Unfortunately I cant find my pump at the minute so Ill have to add a photo of that afterwards, anyway good luck!
