[0036] The present disclosure provides a preparation process of a ceramic copper clad laminate, the process comprising:
[0037] S1, forming a copper layer on the surface of the ceramic backing plate, and then performing a first thermal oxidation treatment on the surface of the copper layer to obtain an oxidized backing plate;
[0038] S2. Place the copper sheet on the copper layer of the oxidized backing plate after the first thermal oxidation treatment, perform the second thermal oxidation treatment on the oxidized backing plate and the copper sheet, and then separate the two to obtain the copper oxide sheet; The surface of the copper oxide sheet separated from the oxide backing plate is the first surface, and the surface of the copper oxide sheet opposite to the first surface is the second surface;
[0039] S3, bonding the second surface to the ceramic substrate, and then performing cladding treatment to obtain a ceramic copper clad laminate.
[0040] In the disclosed proc...
