Rubber Stamping Your Way To Custom PCBs

Rubber Stamping Your Way To Custom PCBs

Lots of of us now outsource PCB creation to board houses abroad, which offer you substantial-good quality boards with progressively remarkable turnaround instances. You might continue to brew up your possess PCB, however, and a reader discovered this wonderful outdated hack from [William Hare] that might be truly worth a seem.

Ignore toner transfer or marker pens — this establish is all about speed. [William] made a decision to use a rubber stamp to swiftly transfer ink to a copper board that can then be etched to create a PCB. It is easy and uncomplicated sufficient. We have used the identical system for silkscreen and pad artwork, but under no circumstances as an etch resist.

The trick is to make quite a few rubber stamps with different circuit aspects, while. The genius portion is that you can then assemble a PCB by only stamping down the many circuit factors you require. The boards will still need to have to be drilled if you’re functioning with by means of-hole parts, but tipster [Shri] notes that the approach is super valuable for developing one-sided surface mount boards.

We have viewed some other exclusive methods to developing PCBs at residence, this sort of as working with a 3D printer to support out. If you have acquired your have ground breaking homebrew PCB hacks, be sure to drop us a line!

Many thanks [Shri Hari Ram] for the idea!
