My first etch! It’ll be a single transistor overdrive for guitar, maybe.

DIY PCB Etching

March 20, 2014

Did I mention that I’m going to try etching my own PCB for the first time this weekend?

I’m going to do it super quick and dirty: hand drawn traces with nail polish, etched with ferric chloride, etch resist removed with acetone. I make a design for a single-transistor boost/dirtbox and that’s what I’ll be etching. My etchant and my board comes in today in the mail. We’ll see how this goes.

Anyone here ever etched their own PCB? What’s your process like?
