I recall the point I started taking electronics seriously, although excited, a sense of dread followed upon the thought of facing the two main obstacles faced by hobbyists and even professionals: ...

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 ...

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 ...

What is Atomic Layer Etching? Atomic layer etching (ALE) is a highly controlled and selective etching technique that removes material layer by layer at the atomic scale. It is a cyclic process that ...

In this technique, fluorine-based plasma chemistry is used for silicon etching, which is combined with a fluorocarbon plasma process to offer sidewall passivation and enhanced selectivity to masking ...

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 ...

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 ...
