Laser etching method and electronic product

The invention discloses a laser etching method and an electronic product. The laser etching method comprises the following steps that a UV coating layer is formed on the surface of a product to be subjected to laser etching; performing laser engraving on the surface of the product on which the UV coating layer is formed through a laser engraving machine; wherein the laser wavelength of the laser engraving machine ranges from 8500 nm to 10500 nm. The UV coating layer is formed on the surface of the product, the laser wavelength of laser engraving is set to be 8500-10500 nm, the used coating layer has the characteristics of laser burning engraving resistance, heat insulation and fast heat dissipation, and during laser engraving, only the coating layer is burnt off, so that surface unevenness caused by laser burning on the surface of a product part is reduced. Meanwhile, the laser wavelength is 8500-10500 nm, the requirement for the wavelength in a special narrow range can be met, the requirement for the paint s
