US 2024/0207931 A1 · PRODUCTION PROCESS OF ALUMINUM SHEET SINTERED NICKEL LAYER

Abstract

The invention discloses a production process of aluminum sheet sintered nickel layer, which comprises the following steps: S1, blending nickel paste: mixing nanometer nickel powder, resin and binder evenly to obtain nickel paste; S2, coating nickel paste: the nickel paste obtained by S1 is evenly coated on the surface of the aluminum sheet through the screen printing process; S3, primary sintering: the laser is used to heat the aluminum sheet coated with nickel paste at a continuous power of 15 W to 250 W; S4, secondary sintering: the use of laser to 200W to 500W continuous power to heat the aluminum coated with nickel paste again, the preparation of aluminum with nickel layer, can be directly completed tin, expand the scope of application of aluminum.
