The Intermediate Guide to Angle Sensor Resistor Laser Trimmer

Posted by Terrazas on December 16th, 2020

The basic principle of laser resistor trimming is to work read more with an exceedingly high-quality laser beam to hit the thick and thin movie resistor and Slash the thick and skinny movie circuit by vaporizing and evaporating the resistor body. The laser beam cuts the thick and skinny movie resistor As outlined by a predetermined Laptop or computer application and improvements the resistance price by changing the geometry of the thick and skinny film resistor. The laser beam is turned off when the thick and skinny film resistor reaches the concentrate on resistance benefit, meaning the laser trimming process is realized.

High accuracy of resistance trimming
