Laser engraving is a kind of silicone button surface treatment process. It uses optical principles to process the surface of the silicone buttons to form required text and symbol patterns. It is now mainly used in mobile phones or electronic dictionary keyboards, remote control buttons, automobile buttons, instrument buttons and control panel buttons, etc. Laser engraved button usually needs to be sprayed with a layer of ink on the surface of the transparent silicone button, and then use the laser carving equipment to engrave the ink on the surface of the silicone button according to the shape and size of the character. So it makes character without ink to achieve light transmission, but the position other than the character does not transmit light. Therefore, under normal circumstances, only the silicone keys with light transmission requirements are considered to adopt the laser carving process. Because of the complicated operation of the laser carving process, the unit price of the silica gel keys after the laser carving process is higher.
