Technical Field

The invention relates to the field of ceramic laser processing, in particular to coatings for enhancing the energy absorption of alumina ceramic to optical fiber laser and a preparation method thereof.

Background

Due to the rapid growth of LED light sources and ceramic circuit boards with high heat dissipation requirements, the laser processing requirements of ceramic substrates are also increasing. When a fiber laser is used for processing such as punching and scribing an alumina ceramic substrate, laser energy cannot be absorbed in some places of the ceramic substrate due to the fact that the surface of the ceramic is smooth and the reflectivity of the ceramic to infrared light is high. Since the optical fiber laser processing is hot melt processing, the laser energy is reflected at the place where the laser energy is reflected, and the processing such as punching and scribing cannot be realized at all, so that the processing yield of the ceramic substrate is low.

The absorption rate of laser energy can be obviously enhanced by coating the color pigment on the surface of the ceramic substrate, so that the punching efficiency is increased, and the yield is increased. After laser processing is completed, the coating on the ceramic substrate must also be easily removed to restore the quality of the ceramic wafer without affecting subsequent processing.
