Abstract

Abstract A module substrate consists of a substrate mounting electronic parts on one surface thereof, a conductor for electrically conducting the electronic parts mounted on the substrate to the other surface of the substrate, a conductive solder for attaching the conductor to a base substrate movably contacting the other surface of the substrate to electrically connect the electronic parts with the base substrate, and a deformable bushing for holding the conductor to maintain the attachment of the conductor to the base substrate regardless of whether the base substrate is moved.
