Michael writes, “Yet another temperature controlled etching bath for producing PCBs at home. But this one has a magnetic stirrer :) Check out the video after the break. Project info at acidbourbon’s blog. Via the contact form.
Here is a guide on how to make your own Ferric Chloride etchant. It’s a relatively simple process that only requires some iron, hydrochloric acid, and air. As the process uses acids please be careful, and do this only if you feel comfortable with it. Get 20g of iron. This can be in the form […]
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 is the fastest way to […]
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 hole and solder it. This […]
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 of the words needed too! […]
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 […]
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 don’t want to etch your […]
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 you tried? This is exactly […]
