Quite a few of us now outsource PCB output to board homes overseas, which supply superior-good quality boards with ever more remarkable turnaround periods. You may even now brew up your personal PCB, however, and a reader uncovered this terrific old hack from [William Hare] that may possibly be really worth a glimpse.
Ignore toner transfer or marker pens — this construct 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 deliver a PCB. It is basic and easy sufficient. We’ve utilised the similar method for silkscreen and pad artwork, but hardly ever as an etch resist.
The trick is to make many rubber stamps with unique circuit factors, even though. The genius section is that you can then assemble a PCB by merely stamping down the numerous circuit components you want. The boards will even now will need to be drilled if you’re doing work with as a result of-gap parts, but tipster [Shri] notes that the procedure is super helpful for making one-sided area mount boards.
We’ve found some other exceptional approaches to creating PCBs at residence, these types of as making use of a 3D printer to assist out. If you have obtained your own innovative homebrew PCB hacks, be certain to drop us a line!
Thanks [Shri Hari Ram] for the idea!
