A contact includes a solder bonding portion, an elastic contact portion, and a suction portion. An undersurface of the solder bonding portion is a solder bonding face which is to be solder bonded to the conductor pattern. The elastic contact portion is connected to one end of the solder bonding portion and bent over the solder bonding portion. When in contact with a conductive member, the elastic contact portion is pressed against the conductive member while being elastically deformed. The suction portion is connected to the solder bonding portion independently of the elastic contact portion. The suction portion is made a suction face for a suction nozzle of an automatic mounter, with its top end being arranged in parallel to the undersurface of the solder bonding portion on the conductive member side of the elastic contact portion.

A printed circuit board according to the present invention is a printed circuit board (4) including a component mounting pin (1) made of a metal wire to connect with a semiconductor chip (10). The semiconductor chip (10) is a surface mounting type semiconductor chip having an electrode pad on its mounting surface for use in a flip-chip mounting system. The component mounting pin (1) is formed by using wire-bonding technology. This printed circuit board (4) is able to decrease malconnections or disconnection caused by a difference between the coefficients of thermal expansion of the semiconductor chip (10) and the printed circuit board (4).

Multiple small conductive and flexible hollow rings (10), each of which is made from a pliable material, provide a flexible connection medium for use between a substrate (23, 80, 82) and a microelectronic device package (88). Each ring is formed to have at least one protuberance (20) on the a ring's exterior surface. The protuberance has an apex (22) or point, which when placed against a surface, will scrub or scrape the surface as the ring is compressed by a force acting on the ring radially. By scrubbing a contact surface with the apex, surface contaminants and layered material that might interfere with electrical signals can be removed.

In order to improve the reliability of an electrical connection between a power supply terminal of a vibrator and an electrode of a circuit board and to improve the efficiency of mounting the vibrator on the circuit board, the power supply terminal is made from a torsion coil spring and a contact portion of the power supply terminal in contact with the electrode of the circuit board is formed by winding. In addition, a torsion coil spring portion is wound around a spindle pin and a housing is provided with a step portion as a space for accommodating the contact portion without interference and a plane portion to which the contact portion faces. Moreover, a partition plate is provided between a pair of power supply terminals or a space where the contact portion can be elastically deformed is surrounded by a box member, a pair of power supply terminals having positive and negative polarities are extended in a bilaterally symmetric direction from torsion coil spring portions to the contact portions, and the power supply terminals are constructed so as to be elastically deformed to allow each contact portion to reach the outside of each torsion coil spring portion.
