Abstract

The invention relates to a technology for selectively metallizing the surface of an oxide ceramic composite material by using a laser surface treatment technology. According to the specific scheme, the technology comprises the following steps: 1) preparing an oxide ceramic composite material containing active factors; and 2) activating the surface of the oxide ceramic and ablating the circuit by using laser according to the circuit drawing; 3) cleaning the ablated sample, putting the ablated sample into a chemical liquid for metallization treatment, and depositing a metal circuit; and 4) drying the cleaned sample. Compared with a traditional metallization process, the method has the advantages of being simpler, faster in preparation, more controllable in process, high in precision, high inbinding force, more environmentally friendly and the like. According to the characteristics of coated metal, the coating has the properties of heat conduction, electric conduction, magnetic conduction and the like, and has very high application value in the fields of large-scale integrated circuits, electromagnetic shielding, multifunctional chips and the like.
