15 Up-and-Coming Trends About Pressure Sensor Resistor Laser Trimmer

Posted by Mariko on December 16th, 2020

The principle of laser resistor trimming is to work with an extremely great laser beam to strike the thick and skinny film resistor and cut the thick and thin movie circuit by vaporizing and evaporating the resistor physique. The laser beam cuts the thick and slender film resistor In line with a predetermined Pc program and alterations the resistance worth by changing the geometry with the thick and slim movie resistor. The laser beam is turned off once the thick and thin movie resistor reaches the goal resistance worth, meaning the laser trimming process is recognized.
