HowTo: How to make printed circuit boards
( Robert Stark)
Step 3 : The tank
|
| | This was supposed to be a picture of my tupperware etchant tank but the file names got messed up somehere. Just use your imagination........
As you can see here, my tank is just a Tupperware container with a good sealing lid. It's very important to have a good sealing lid. You can store etchant indefinably, but it's vapors are corrosive. Plus, you never know when you are going to knock the darned thing over. Sometimes I will etch in this tank, other times I will use another container that best fits the boards I am building at the time. (Tupperware is a wonderful thing!) In this HowTo I am etching 12 channel SSR boards. (see my other HowTo on SSR building) These boards are long and narrow so I'm using a spaghetti container (see picture in next step).
