HEAT RADIATOR PLATE OF COPPER OR COPPER-CONTAINED ALLOY, AND ITS JOINING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method of joining a DBA substrate and a heat radiating member by brazing or by soldering, and also a heat radiator plate manufactured by the joining method. SOLUTION: A Cu plate or a Cu-contained alloy is joined to a foil or a particle-like Sn-based alloy by inserting the foil or the particle-like Sn-based alloy between the Cu or the Cu-contained alloy, and heating the alloys at a temperature not lower than the melting point of the Sn-based alloy.
