Make's PCB etching tutorial

Posted on Saturday, February 20th, 2010 in idle, skills by Ian

We enjoyed this (sponsored) segment from Make about etching circuit boards. Like Collin, we got our start etching boards we found on the web, at first with toner transfer and later UV photo masking. We didn’t know how the circuits worked, but it was still exciting to build something cool.

Our current method for single-sided prototype boards is about the same as in the video, but we use inkjet masks. Usually a mix of all ink colors, often called high quality black, has better UV resistance than black ink alone. We expose the board for 1 minute and 28 seconds under a tanning lamp from a thrift shop.

    Hi Ian,

    Great work!

    Normally I develop PCB board printing my circuit on Glossy paper using a laser toner printer and it works pretty well for up to 8 mils lines.

    But in fact your process appears superior.

    Best Regards,


    P.S.: I am missing your email about how to integrate tweeter and google web applications to receive data from microcontrollers ;-)

    One of the best videos I’ve seen on the subject. Well done!

    Thanks guys, but I can’t take credit on this one. MAKE: put this video together. I thought it was great too.
