High Precision Laser Resistor Trimming System

Laser resistance modulation locates a very thin laser beam on the thick film resistor, the beam cuts the resistor according to the computer predetermined program, and changes the resistance value by changing the cross-sectional area of the resistor.
Laser resistance modulation locates a very thin laser beam on the thick film resistor, the beam cuts the resistor according to the computer predetermined program, and changes the resistance value by changing the cross-sectional area of the resistor.
At the same time of laser cutting resistance, the resistance value is measured in real time through the high-speed measurement system to keep it close to the target resistance value.
When the resistance reaches the target value, the laser beam is turned off, so as to realize the precise adjustment of the resistance.
The laser resistance modulation system has a variety of adjustment functions, which can adjust the thickness of thin-film resistor network, capacitor network, ceramic based thin-film integrated components and realize the function adjustment of hybrid integrated circuits.
