Why You Should Spend More Time Thinking About Current Sensor Laser Trimmer

Posted by Cataldo on December 16th, 2020

The principle of laser resistor trimming is to work with an extremely wonderful laser beam to strike the thick and thin movie resistor and Minimize the thick and slim movie circuit by vaporizing and evaporating the resistor system. The laser beam cuts the thick and skinny film resistor As outlined by a predetermined Pc program and modifications the resistance price by modifying the geometry on the thick and skinny film resistor. The laser beam is turned off once the thick and thin film resistor reaches the goal resistance worth, meaning the laser trimming system is understood.
