Chris Holden's Circuit Board Etching Experiments

Gareth Halfacree


Making your own printed circuit boards is a rewarding experience, but it can also be fraught with difficulties. Hove-based maker Chris Holden demonstrates this perfectly in his blog post from the weekend, showing how larger circuit boards can be challenging to produce even with access to a high-end laser-cutter to precisely remove the mask layer - in this case, off-the-shelf spray paint. While the hit-rate of five failures to one working board isn't great, it was undeniably a great learning experience for all involved - although Chris has indicated he'll be sending the Gerber files off for professional production once the design has been tested and validated!

It took five goes to get a working PCB. And I'm still not 100% happy with it. But we've got something that works, so - as far as testing needs to go - it'll have to do!
