20W Fiber Laser Etching Blank PCB

Описание к видео 20W Fiber Laser Etching Blank PCB

This is a 20W pulse nanosecond fiber laser etching a PCB blank. Maximum power, 1000mm/s, at 20kHz repetition rate and 10x loops. With this setting I didn't reach the bottom of the copper layer but it is definitely possible at about 500mm/s and 7 loops. Or just simply with more loops..
Great precision for manufacturing microwave metamaterial building blocks.
Done in the diy-optics.com labs..
