[Stephen] often finds the need to make his own PCBs at home, and when he got the urge to do some etching recently, he realized that he was fresh out of “Ferret Chloride and Bureaucratic Acid*.” ...

Although the typical cliché for a mad scientist usually involves Bunsen burners, beakers, and retorts, most of us (with some exceptions, of course) aren’t really chemists. However, there are some ...

After my DIY article “Build Your Own Headphone Amp” in the May 25 issue, the good folks at Radio World asked me to share the process by which I make printed circuit boards. There are usually two ...

Through precise control of the etching process, a researcher in Oxford University’s Photofabrication Unit has made the reliable production of high resolution printed circuit board (PCBs), with ...

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 ...

The copper layers of a printed circuit board are the central focus of any circuit design, the other layers only support or protect the circuit, or simplify the assembly process. For starting PCB ...
