After more than a decade of research and development, Tokyo Electron Miyagi Ltd. has introduced an innovative semiconductor ...

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.

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 ...

(MENAFN- GetNews) Although extremely similar in some respects, the technological aspects of etching vs engraving also share lots of bold dissimilarities. In a earth full of complexities and robust ...

CNC machining mills away copper using a CNC router and design software chemical etching uses UV light, photo-resist, and chemicals to remove copper CNC machining is safer and less wasteful, but slower ...

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 ...

In dry etching, the trajectory of accelerated ions is non-uniform and non-vertical, due to collisions with gas molecules and other random thermal effects (figure 1). This has an impact on etch results ...

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 ...

There may be nothing new under the sun when it comes to etching PCBs with UV light, but [Heliosoph] has brought finer control to a used face tanner he bought that now exposes his boards in ~50 seconds ...
