[Frankie] and [Bryan] have figured out a way to use the laser to chemically activate an etching process. See experiment part 2 as well. First, to be clear, they are using a quality 40W Epilog Zing ...

They call their machine the DiyouPCB. DiyouPCB is an open source PCB etching project consisting ... which they used to do preliminary testing and laser tuning. The X and Y axes run on brass ...

With any questions, please feel free to contact the Radiation Safety Office A Laser Cutter, sometimes called a 3D laser cutter, Laser etcher, or laser prototyping machine, is not to be confused with a ...

the better your chip is – and to etch more you need to go smaller. This is why the machine uses extreme ultraviolet light. The laser light of this plasma has a wavelength of around 13 nanometers ...

So now the machine is set up ... which is when high-powered laser is used to cut, etch or engrave a material. Laser cutting is an increasingly common technique taught in schools.

Whoo! I'm using a "20W" 450nm blue laser etching machine for these experiments, and while a bigger or pulsed laser would work better, it did a pretty ok job. Trump says he’ll end daylight saving ...
