How to cold solder

A quick demo on how to use Electric Paint to cold solder your board onto almost any material

Cold soldering is a great alternative to traditional soldering and doesn’t require a solder iron. Instead, all you need is some Electric Paint! In this tutorial, we’ll demonstrate how to cold solder with our electrodes stencil and the Touch Board and show you how to cold solder onto other materials!

We also provide a template so that you can easily print out the pitch of the electrodes of the Touch Board or Pi Cap.

Step 1

Touch Board and Pi Cap grid

First, prepare the stencil for your Touch Board with Electric Paint. You can download the stencil here. If you don’t know how to prepare the stencil, you can follow our stencil tutorial to learn how to do this.

Once the stencil is ready, align your Touch Board above the connectors.

Step 2

Cold solder

To cold solder, all you have to do is carefully squeeze a droplet of Electric Paint into each electrode that you want to connect to the paint beneath. When you are done, leave the paint to dry. The Electric Paint will act as a conductor and as a glue. That’s it, that’s how you cold solder!

Be careful not to move the Touch Board, otherwise, you risk smudging the paint and shorting the electrodes. Shorting the electrodes will not break the board, but you will need to clean it before you can use it again.

Step 3

Cold soldering the Pi Cap

As the Pi Cap has the same pitch for the electrodes as the Touch Board, the above method also works for the Pi Cap. You can use it to make your own piano!

Step 4

Cold solder onto other materials

You can cold solder with Electric Paint not only to paper but also onto other materials, for example, copper tape. This is useful for quick prototyping or when you need to securely attach your board to other conductors.
