Abstract: A laser guided nano-brazing method for a reinforced aluminum composite material having high volume fraction silicon carbide particles, comprising 4 steps: nanocrystallizing the surface of the reinforced aluminum composite material having high volume fraction silicon carbide particles, preparing solder material, assembling pieces to be soldered, and dual-beam laser brazing. The use of nano-technology for the brazing of reinforced aluminum composite material having high volume fraction silicon carbide particles, and the use of dual-beam laser technology for brazing temperature field control enhance the humidity during the brazing process of said material and filling ability of the solder material, and satisfy the strict requirements of electronic packaging.
