You might assume that you need a lot of expensive stuff to make your own PCBs, but that isn’t the case: you can do it with a vinyl cutter and a few common chemicals and tools. [Emiliano Valencia] has laid out the entire process. While we’ve seen plenty of make your own PCB guides before, this one goes a bit further as it covers using the vinyl cutter to make solder masks, so you can use it for surface mount designs.
The end result of the process that [Emilano] lays out is the tinyDice, a cute little electronic die that can fit on a keyring. The whole process is very well written up, and even experienced PCB makers will probably find a few useful tricks here.
The really interesting part for us was using the vinyl cutter to make three parts of the process: the etching mask, the solder mask that protects the traces and the solder stencil that applies the solder to the pads for surface mounting. Continue reading “Making PCBs With A Vinyl Cutter”
