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

[Quinn Dunki]’s Veronica, a homebrew computer based on the 6502 CPU, is coming along quite nicely. She’s just finished the input board that gives Veronica inputs for a keyboard and two old Nintendo ...

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 ...

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 ...

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 ...

(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 ...
