The present invention relates to the technical field of copper clad laminates, and specifically to a welding method for solving the problem of selective silver-plated surfaces of ceramic copper clad substrates. The present invention firstly pickles and sandblasts the surface of the copper clad substrate, and after the pickling and sandblasting, one side of the copper clad substrate is used as a graphic surface for selective silver plating; the other side is used as a non-graphic surface for full silver plating to obtain a silver-plated copper clad substrate. The non-graphic surface of the silver-plated copper clad substrate is then sandblasted, coated with a composite slurry, and subjected to high-temperature heat preservation to remove organic solvents. After the pickling and sandblasting, a welding sheet is attached to the non-graphic surface of the silver-plated copper clad substrate, sintered and dissolved at high temperature, and then a chip is placed, and high-temperature welding is performed to finally prepare a ceramic copper clad substrate. The finished product prepared by the present invention has good welding bonding strength, heat dissipation and strength, and therefore has broad application prospects in the technical field of copper clad laminates.
