[Sebastian] probably didn’t think he was wading into controversial waters when he posted on his experimental method for etching PCBs (in German). It’s not like etching with hydrochloric acid and ...

While low-cost professional PCB fabrication has largely supplanted making circuit boards at home, there’s still something to be said for being able to go from design to prototype in an afternoon.

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 ...

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 ...

On Sunday, the Minneapolis Institute of Art hosted the last day of “Rembrandt in America,” an exhibition it proudly described as “the largest selection of Rembrandt paintings assembled in the United ...

Photochemical etching is a machining technique that leverages the principles behind photography to shape a piece of sheet metal and turn it into a finished product or component. The modern form of ...
