ELECTRIC CONTACT USING RESIN SOLDER, ELECTRIC CONNECTOR AND CONNECTION METHOD THESE TO PRINTED WIRING BOARD

摘要

PURPOSE: To mount an electric contact and an electric connector to a printed wiring board without soldering and to carry out mounting to the printed wiring board by an automatic machine even in the case where the electric contact is made super small. CONSTITUTION: The electric contact is connected to the printed wiring board 200 having a conductor 210 provided on a surface or an intermediate layer; and a through hole penetrating through the conductor or a recessed part 220. The electric contact is provided with a projection 110 inserted into the through hole or the recessed part; and a connection part 120 connected to a conductor of the partner side member. A part of at least the projection connected to the conductor of the printed wiring board is formed by a lead-free superconductive plastic comprising a conductive resin composition. The electric connector C is provided with the electric contact 100; and an insulation housing 500 retaining the electric contact such that the projection and the connection part are projected to the outside.
