Step 4Let's Get Etching
Now that you've got your schematic inked and your Muriatic Acid and Peroxide, let's mix our etching agent. Get yourself a hard plastic container to pour these chemicals in. I like to use a container that is about the size of the board I'm etching to cut down on necessary etchant.
Grab some gloves and put them on or risk chemical burns. I've splashed it on myself and it does burn.
Mix around two parts peroxide to one part acid into your container. Always add the acid to the peroxide and pour the acid down the side of the container instead of splashing it into the middle. This should cut down/eliminate splashing. Drop the board in and lightly agitate the fluid around the board by swirling it. This step is not necessary but it will cut down on etching time. This particular etch took less than two minutes. The container will get hot so be very careful. Grab yourself a plastic fork to manipulate the board and a small container of water to dunk the finished board in upon completion.
