pcb

Being able to make your own printed circuits boards is a skill that can come in handy. There are several ways to do this and I will describe the one that I use. First part of the process is the creation of a layer on top of the copper that prevents the solvent to dissolve it.

During the process of manufacturing of home-brew PCBs you need to expose the photosensitive film with ultraviolet light. A cheap and low power solution can be found in UV led strips.
