How does laser trimming work?

Laser trimming optimizes the electrical properties of a circuit by specifically adjusting resistance values with a laser beam. During this process, the circuit is connected to the laser trimmer’s integrated measuring system via a probe card. The resistor material is then removed in real time by the laser beam until the desired target value is reached.
