Patent ID: 8745841

Claim:
A method for producing an aluminum bonding member, said method comprising the steps of: preparing a tubular member of a material which does not melt at a temperature close to a melting point of aluminum or an aluminum alloy; putting said tubular member in a die so that opening end portions of the tubular member are open to the outside of the die; arranging a metal/ceramic circuit board, which has a metal circuit plate bonded to a ceramic substrate, on the die so as to close an opening portion formed in a top face of the die; injecting a molten metal of aluminum or the aluminum alloy into said die; and cooling and solidifying the injected molten metal to cause a portion of said tubular member in said die to contact a solid aluminum member to be bonded thereto while causing the metal/ceramic circuit board to contact the solid aluminum member to be bonded thereto.
