Laser resistor trimming works by using a laser to selectively remove material from the resistor, adjusting the resistance of resistor to a specific value. The laser is directed at the resistor and material is removed in small increments. The process is repeated until the desired resistance value is achieved.

Laser resistor trimming is used in a variety of applications where precise resistance values are required. A common application is the manufacture of electronic devices such as computers, smartphones and other consumer electronics.
Another application of laser precision resistance adjustment is in aerospace and defense industries. High reliability components that can withstand extreme environments are needed in these industries and Laser resistor trimming is an effective way to ensure that the resistors meet these requirements.
There are several benefits of laser precision resistor trimming. One of the main advantages is high accuracy as it can adjust the resistance value of resistor to 0.1% or less of its original value, which is much more accurate than other resistor trimming methods.

Another benefit of precise laser resistor trimming is speed. It can be completed quickly, which makes it ideal for high-volume manufacturing applications. In addition, as Laser resistor trimming is a non-contact process, there is no risk of damaging resistors or other components during trimming process.
During the final stages of component or circuit manufacture, resistor trimming employs a laser to ablate a small amount of resistor material, resulting in an increase in resistance through a reduction in the resistors effective cross section.
