Abstract:
An electrical connector includes a first connector body having an interlocking feature extending therefrom. The interlocking feature interlocks the first connector body with a complimentary interlocking feature extending from an adjacent second connector body to distribute a lateral force on either the first or second connector bodies across the adjacent connector body thereby reducing a rotational moment at a base of each electrical connector connected to a printed circuit board (PCB).
Abstract:
A memory module includes a module substrate and a plurality of package units mounted to the module substrate such that they partially overlap each other. Each package unit has at least one memory semiconductor package attached thereto. Each package unit includes a flexible substrate, which has outer terminals provided over a lower surface adjacent to one edge thereof to form electrical connections with the module substrate, and the memory semiconductor package attached to one surface or each of both upper and lower surfaces of the flexible substrate.
Abstract:
The invention provides a subassembly to facilitate co-planar vertical surface mounting of subassembly boards. By “vertically mounting” is meant that a subassembly circuit board with a major surface is mounted perpendicular to the major surface of a circuit motherboard. In accordance with the invention, a subassembly for co-planar vertical surface mounting comprises a subassembly board coupled between a pair of base headers. Advantageously one base header comprises a plurality of mounting lugs secured to a transverse element in a co-planar configuration. The other base header conveniently comprises a plurality of connector pins secured to an elongated header element in co-planar configuration. The two headers interlock with the board to provide connection and co-planar support. Edge metallization of the subassembly board can provide enhanced thermal or electrical connection to the underlying portions of one or more lugs.
Abstract:
An assembly includes a first electrical component having a first electrical property, a second electrical component having a second electrical property, where the first electrical property and the second electrical property are substantially identical, a housing that holds the first electrical component and the second electrical component, first terminals on the housing that contact the first electrical component, and second terminals on the housing that contact the second electrical component.

Abstract:
A sectional connector includes a main connector having pins in two rows, one or more first sub-connector having pins in one row, and a second sub-connector having pins in one row, sequentially connected through engagement of dovetail grooves and dovetail tenons correspondingly provided on side surfaces of the main connector and the sub-connectors in contact with one another. The sectional connector may substitute for conventional PC104 and PC104 PLUS industrial computer connectors having pins in 2null2 rows and pins in 2null2null4 rows, respectively, for connecting buses. Number of the first sub-connectors used in forming the sectional connector could be changed, depending on actual need in designing an industrial computer. The sectional connector enables easy and firm connecting and soldering of pins to a PC board row by row.
Abstract:
A vertically mountable semiconductor device including a plurality of bond pads disposed proximate to a single edge thereof. The bond pads are bumped with an electrically conductive material. The semiconductor device may also include a support member. Alternatively, the semiconductor device may be laminated to one or more adjacent semiconductor devices. The present invention also includes a method of attaching the semiconductor device to a carrier substrate. Preferably, solder paste is applied to terminals on the carrier substrate. The semiconductor device is oriented vertically over the carrier substrate, such that the bumped bond pads align with their corresponding terminals. The bumps are placed into contact with the solder paste. The bumps and solder paste are then fused to form a joint between the each of the bond pads and their respective terminal, establishing an electrically conductive connection therebetween and imparting structural stability to the semiconductor device.

Abstract:
The invention is component module (20) for combining a plurality of components (21, 23, 25, 27 and 29)into a single module (20) for use with a printed wiring board. A plurality of components, each component having a pair of contacts (21a,21b), are formed into the module with a plurality of insulating spacers (2,24,26 and 28). There is one spacer between adjacent components, said spacers serving to insulate adjacent components from each other and to secure the components together to form the module.
Abstract:
SIP or ZIP packages are provided with locking elements of snap fasteners, or have package alignment tabs to combine several IC packages into an IC package assembly. Using a DIP printed circuit board socket, a high density DIP module, for example, a high capacity memory chip, is assembled. The leads of the module are inserted into a motherboard that carries the external conductors to be connected with the inner circuits of the package assembly, and soldered to the motherboard. To make the IC package assembly compatible with a conventional DIP socket, a plastic spacer can be provided between the IC packages. A retaining clip may be used to allow the IC package assembly to be repeatedly inserted and removed to and from the socket without the risk of falling apart.
