355nm UV laser is used for drilling, engraving key PCB circuit board

The working principle of the car remote control key is to first send out a weak electric wave through the key, the electric wave signal is received by the car antenna, the signal code is recognized by the electronic control unit, and then the actuator (motor or electromagnetic coil) of the system performs the opening/closing action . To complete these intelligent instructions, it is necessary to rely on the mother of intelligent systems: PCB circuit boards.


PCB circuit boards have the characteristics of high density, high integration, packaging, and miniaturization, and are widely used in smart electronic products such as household appliances, smart phones, and PCs.


PCB circuit boards need to use ultraviolet laser drilling, cutting, engraving and other etching techniques in the production process. Ultraviolet laser has a wavelength of 355nm, which is a cold light source. The heat affected zone of laser cutting is particularly small
