Joining of metal for high heat dissipation, such as heat sink, involves applying solder paste containing tin and zinc to junction of metal such as (aluminum) alloy or (copper) alloy, and removing solder paste
A solder paste containing tin and zinc is applied to junction portions of two or more metal chosen from aluminum, aluminum alloy, copper and copper alloy, so as to join the metal. The solder paste is then removed.
