Abstract

Abstract A method of making an electric circuit device by connecting first and second electrical circuit components through an electrical connecting member. The method comprises effecting internal heating such as supersonic heating, high-frequency induction heating, high-frequency dielectric heating or microwave heating at first connecting regions between the connecting portions of the first electrical circuit component and the first ends of the electrically conductive members of the electrical connecting member. The same internal heating may also be effected at second connecting regions between the connecting portions of the second electrical circuit component and the second ends of the electrically conductive members of the electrical connecting member. In consequence, alloying takes place in first and second connecting regions so as to connect the first and second electrical circuit components through the electrical connecting member.
