Abstract:
A main substrate is provided with a wiring pattern on its surface and in the inner layer. A wiring pattern for connecting the signal line or power line of the main substrate to an external circuit is formed on the flexible printed circuit. A connection terminal to which a corresponding wiring pattern is connected is formed at the tip of the flexible printed circuit. A through-hole is formed between the wiring patterns. Potting resin is potted in each through-hole and around it. When the resin hardens, the potting resin joints the main substrate and the flexible printed circuit.

Abstract:
A thermal expansion coefficient of a module substrate 8 is different from that of a package substrate. There is not any place where stresses generated in Interfaces between soldering balls 5 and the substrate are released. These stresses are largely applied to soldering bond, the soldering balls are strained, deformed, or cracked, and there has been a problem in long-time reliability. Slits are disposed on opposite sides of each soldering ball in a vertical direction to a side in an outer peripheral side of the package substrate, accordingly the stresses applied to the soldering balls are weakened, and the soldering balls are prevented from being strained, deformed, or cracked. When soldering strains are reduced in this manner, there can be provided a surface mounting type semiconductor package and system module having high reliability, low cost, and satisfactory electric characteristics such as low capacitance and low inductance.

A plurality of semiconductor packages may be inserted in a vertical direction into corresponding insertion holes. The module may include a heat sink composed of a base plate and a plurality of protrusions. The protrusion may extend downward from the base plate.
Abstract:
Disclosed is a terminal structure of a multi-layer substrate and a method for forming the same. In the terminal structure, a plurality of terminals are formed on at least two adjacent substrate layers, each of the terminals being spaced from adjacent ones to a predetermined interval. Openings are formed in at least one of the substrate layers. Each of the openings is formed between each adjacent ones of first terminals in the at least one substrate layer, and spaced from the each first terminals to a predetermined gap, and has a size same as that of the first terminals. The substrate layers are stacked one atop another and compressed together so that second terminals formed on at least one corresponding substrate layer are projected to a plane of an outermost substrate layer on which corresponding terminals are formed. The terminal structure and the method can secure a predetermined interval to a plurality of terminals in a package when the terminals are formed as well as simplify formation thereof.

The power substrate is inserted in a housing (1) as base plate and together with the same forms a standardized power part from whose top side (11) there are projecting terminal pins (5) which are soldered by through-soldering to via holes of the board (4). The circuit board (4), in a strip portion (6) thereof that remains free, has contact pads (7) as control and power terminals by means of which the module can be soldered directly into the slot-like opening of a system circuit board (8).
Abstract:
An integrated circuit (IC) having a plurality of IC modules, each IC module having attachment surfaces to which elements of the IC are attached, and each IC module having interlocking edges adjacent to the attachment surface. The interlocking edges of adjacent IC modules are interlocked to form a structural connection between the IC modules. The interlocking edges are a plurality of teeth and recesses, which are arranged in rows. The teeth are securely received by a respective recess in an adjacent interlocking edge to create a structural connection between adjacent IC modules. In addition, the interlocking edges can be a ridge member or a ridge recess, where the ridge member or ridge recess is securely received by a respective ridge recess or ridge member of an adjacent IC module to create a structural connection between the IC modules. The interconnection edge can also be a combination of the ridge member, ridge recess, and/or the rows of teeth and recesses. The attachment surfaces of adjacent IC modules can be co-planar and non-planar, depending on the shape desired. The elements on the IC modules communicate using external pathways and/or internal pathways using conventional wire-bond techniques or using conductive layers within the IC module. The IC module is formed of conventional Si wafers. Using this configuration, an IC can be constructed that utilizes less real estate, fits in non-planar spaces in a housing, and has improved speed due to reduced pathway lengths.
