PCB ecthing at home using photo transfer method

Monday, February 27th, 2012

Blondihacks wrote an in-depth tutorial on how to make PCBs made at home using pre-sensatived photo-PCBs. We especially liked the board design optimization for home etching tips. Wide traces, big vias, and using a ground plane are all strategies we use to get good DIY photo-transfer PCBs too. DIY etching...

Easy vias on homemade double sided PCBs

Tuesday, March 16th, 2010

Double sided home-etched PCBs require a lot of patience and luck. Both sides need to be aligned properly, and via wires have to be soldered between the layers so top and bottom are connected. The usual process for connecting the layers is to insert a small wire in each via...

More PCB art from Ril3y

Saturday, March 6th, 2010

Ril3y left a comment on the Lincoln PCB with a few other artistic boards. Not really a "circuit" but it was an attempt at how cool I could get a pcb. Next is to bake in a circuit next time. I try to use copper to do quite a bit...

Make's PCB etching tutorial

Saturday, February 20th, 2010 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...

DIY Bus Pirate PCBs

Wednesday, January 6th, 2010

s3c posted this home-etched Bus Pirate v3 PCB in the forum. Nice work! Do you etch your own PCBs? We send double-sided PCBs to the board house, but still etch simple single-sided designs. Bus Pirate v0, va, and v1 were all etched on the stove in Ian's kitchen. If you...

PCB etching tutorial

Monday, November 2nd, 2009

Instructables user ArduinoFun shows how to etch PCBs at home using a positive photo-resist. This method involves printing the PCB design on an inkjet transparency, exposing it under a UV light, developing in a basic solution, then etching in an acid. Do you etch your own PCBs? What methods have...
