    Abstract: An improved multi-chip module includes a main circuit board having an array of electrical interconnection pads to which are mounted a plurality of IC package units. Each IC package unit includes a pair of IC packages, both of which are mounted on opposite sides of a package carrier. The package units may be mounted on one or both sides of the main circuit board. A first primary embodiment of the invention employs a laminar package carrier having a pair of major planar surfaces. Each planar surface incorporates electrical contact pads. One IC package is surface mounted on each major planar surface, by interconnecting the leads of the package with the contact pads on the planar surface, to form the IC package unit. A second primary embodiment of the invention utilizes a carrier substrate which has a pair of recesses for back-to-back surface mounting of the IC package pair. The two IC packages may be in contact with opposite sides of a heat sink layer embedded within the carrier substrate. Each resulting IC package unit is surface mounted to the main circuit board. A third primary embodiment of the invention incorporates features of both the first and second primary embodiments. One of the packages is mounted on a planar surface of the carrier right-side up, while the other package is mounted on the carrier in a recess upside down. Several variants of this embodiment are possible. Either the IC package that is mounted on the planar surface of the carrier, or the IC package that is mounted within the recess, may be mounted adjacent to the main circuit board. In the former case, the adjacent package of the package unit fits within a recess on the main circuit board. In the latter case, the adjacent package of the package unit mounts on a planar surface of the main circuit board. For any of the three primary main embodiments, the carrier may be equipped with its own set of interconnection leads which interface with the interconnection pads on the main circuit board or connection may be made directly between the leads of one package and the interconnection pads of the circuit board.

    Abstract: A novel surface-mount electrical component for mounting on a circuit board. The electrical component includes at least one pin and a retaining surface. The pin serves as both a point of electrical contact between the electrical component and the circuit board and as a solder-anchoring point. The retaining surface is remote from the pin and serves as an additional solder-anchoring point for restricting the movement of the electrical component on the circuit board. Both the pin and the retaining surface are coplanar, ensuring even soldering of the electrical component to the circuit board.

    Abstract: Terminal pins with two lateral portions and a bridge-shaped elevated middle portion are provided. The terminal pin and perpendicularly rising hybrid circuit typically together have an inverted T shape. On the one hand, the hybrid circuit stands on its own on the substrate without further means of assistance and can be soldered. On the other hand, the bridge-shaped construction effects a sufficient elasticity and carrying capacity relative to swivellings, or respectively, accelerations, as well as effecting the presence of two defined support surfaces whose co-planarity is guaranteed by the springing configuration of the terminal pins.
