I use this etchant too when I make pcbs. It works pretty good. I have a good tank made up to etch my boards in and eventually I will get it put up on my website, with 100 other projects I’m ...

These days, PCB fab houses are just about everywhere, and you can’t go buy a taco without walking past eight of them. Still, some out there still like to etch their PCBs at home.

A step-down PCB is simply a multilayer PCB whose board thickness is reduced (stepped down) in a few places. The step-down is ...

Discover how to make PCBs at home using SLA 3D printers. Learn techniques, ... Etching precision: Over-etching can damage the traces, while under-etching leaves excess copper, ...

PCBs are manufactured using CNC machining or chemical etching. CNC machining mills away copper using a CNC router and design software; chemical etching uses UV light, photo-resist, and chemicals ...

The method of printing PCBs has not changed for decades. In the early days of imaging circuit boards a substrate (copper laminate) was screen printed with a liquid etch resist; this was then oven ...

Here we're prepared to start etching. We have baking soda, water, acid, peroxide, a cereal container, a containment bucket to catch spills, an air pump to agitate the solution and our board.
