Research on laser physical and chemical modification of metal complex

Through laser irradiation on the nonmetal material adulterated with metal complex, the irradiated area could be chemically plated on copper and nickel after the sensitizing treatment, so the electricity conducting channel is formed and the quality of metal conductor appears. The non-irradiated area still remains the original nonmetal quality. The Nd:YAG laser beam, after going through dynamic focusing system, was reflected by galvanometers and then focused by f-theta lens on the surface of metal complex. Through the 1, 3, 10 and 20 kHz laser modulation comparative experiments, the copper-plate thickness exceeded 11 μm, and the nickel-plate thickness exceeded 2 μm. In this way, the quality of metal and nonmetal coexist on the surface of the same material.
