Abstract
Abstract A manufacturing method for a supermicro-connector, comprising: a step of fixing a plurality of conductor wires, arranged substantially parallel to one another, by means of an elastic insulator interposed between the conductor wires, thereby making a composite structure formed of the conductor wires and the insulator; a step of cutting the composite structure along a plane extending at right angles to the conductor wires, thereby making a plurality of composite chips; a step of removing the insulator from at least one cut surface of each of the composite chips by dissolution by means of an agent, thereby exposing the respective end portions of the conductor wires for a predetermined length; and a step of forming solder bumps individually on the respective exposed end portions of the conductor wires.
