The electronics industry uses lasers to remove oxides: The electronics industry requires high-precision decontamination, and is particularly suitable for laser deoxidation. Before the circuit board is soldered, the component pins must be thoroughly deoxidized to ensure optimal electrical contact. The pins must not be damaged during the decontamination process. Laser cleaning can meet the requirements of use, and it is very efficient, only one pin needs to be irradiated with laser light once.
