Thin Film Laser Trimmer: 10 Things I Wish I'd Known Earlier

Posted by Kiara on December 16th, 2020

The theory of laser resistor trimming is to make use of an incredibly high-quality laser beam to strike the thick and skinny movie resistor and Slice the thick and thin movie circuit by vaporizing and evaporating the resistor body. The laser beam cuts the thick and slim film resistor Based on a predetermined Personal computer application and changes the resistance price by transforming the geometry of the thick and thin movie resistor. The laser beam is turned off if the thick and thin film resistor reaches the focus on resistance value, which means the laser trimming course of action is realized.
