The bonding pads along the periphery of the ceramic substrate are lead-bonded to a second substrate with printed wiring on at least one of the surfaces and solder connection at the bottom.

Abstract: An integrated circuit package which has an integrated circuit mounted to a substrate. The package includes a plurality of bond wires that couple bond pads of the integrated circuit to corresponding bond pads of the substrate. The bond wires may have an essentially uniform bond wire density about an entire outer perimeter of the integrated circuit including the corners of the circuit. The integrated circuit and bond wires are enclosed by an injected molded plastic housing. It is believed that the bond wires located at the corners impede the flow of the injected plastic and reduce the amount of wire sweep in the package from packages in the prior art. Additionally, the essentially uniform bond wire density may create a uniform fluidic resistance to the injected plastic. The uniform resistance also reduces the amount of wire sweep from packages in the prior art. The bond wires located at the corners may be dummy wires that are not electrically connected to the integrated circuit.

Because this substantially equalizes the pressures applied on the respective inner-leads during the mounting of the IC chip, preventing the bonding pressure of the mounting from being unbalance, it is possible to provide an IC chip mounting FPC board having a high bonding reliability.

Over the second bus line other modules situated outside the housing or the rack can be connected to this first bus line. The first and the second bus line together form a common bus line, which is preferably designed as a ring line.

Abstract: One end of a terminal is formed in a tube shape, and a front end of a covered electric wire in which a part of a covering is peeled is inserted to the one end of the terminal, and is uniformly caulked from a periphery. A length of the peeled covering is shorter than a depth of the tube-like portion of the terminal. Accordingly, a part of the covering is received in the tube-like portion and caulked so as to serve as an operation of a packing, thereby preventing a water and an air from entering into an inner portion of the tube-like portion. Further, since the tube-like portion is uniformly caulked so as to be closely contact with the electric conductor, it is possible to obtain a comparatively large contact area, and it is possible to obtain a stable conduction.

Accordingly, a plastic heat-shrink tube is caused to adhere tightly to the terminal part and shielding covering, except for the stripped front end portion of the terminal part, so that the front end portion is exposed. As a result, the heat-shrink tube prevents or alleviates the mismatching of the differential impedance.
