Abstract:
An electrical unit comprising: a housing main body (1) having an opening providing access to an interior thereof, the housing main body having a pair of substantially opposing walls (2, 3), each having pairs of protrusions (7) provided on an inner surface thereof, a space being defined between the pairs of protrusions; a circuit board (16) which is supported with respect to the housing main body between the pairs of protrusions; a mounting arrangement (8) adapted to receive and retain an electrical component (13), the mounting arrangement being provided on an inner surface of the housing main body; and an electrical component having at least one conductive contact pin (15) which has a substantially constant diameter over at least a contact portion thereof, the electrical component being mounted with respect to the housing main body by the mounting arrangement and being electrically connected to the circuit board by the contact portion of the at least one contact pin.
Abstract:
A micro solder pot includes a dielectric substrate having at least one hole formed therein, a conductive coating coupled to the interior of the hole, and at least one heat transfer pad spaced from the hole in thermal communication with the conductive coating of the hole. When the heat transfer pad is exposed to a heat source, the conductive coating inside the hole is heated. The micro solder pot may also include a thermally activated conductive material disposed within the hole. When the heat transfer pad is exposed to a heat source, the thermally activated conductive material becomes liquidus such that a component can be inserted into the liquidus material. When the heat source is removed, the thermally activated conductive material cools to couple the component to the conductive coating in the hole.

Abstract:
A multilayer module comprised of stacked IC package layers is disclosed. A plurality of layers preferably having ball grid array I/O are stacked and interconnected using one or more interposer layers for the routing of electronic signals to appropriate locations in the module through angularly depending leads. The stack is further comprised of an interface PCB for the routing of electronics signals to and from the layers in the module and for connection to an external circuit.
Abstract:
El sistema permite conexionar mecánica y eléctricamente módulos de circuitos impresos, basándose en que el correspondiente módulo se fabrica con una serie de lengüetas (1) distribuidas uniformemente por su contorno y dotadas de dos secciones simétricas (1a) y (1b), en donde la configuración de las lengüetas (1) es igual y simétrica al espacio determinado entre ellas, para permitir el interacoplamiento correspondiente, estableciendo la unión mecánica y a su vez la eléctrica por el contacto que establece la superficie lateral metalizada de las lengüetas y la superficie, tanto superior como inferior, de los módulos (7). En las esquinas se sitúan lengüetas asimétricas (2) que cuentan con una única sección y que está posicionada perpendicularmente a una de las secciones de la lengüeta adyacente y simétrica (1) de esa esquina. Mediante las lengüetas (1) y (2) se realiza una interconexión fácil y sencilla, por desplazamiento vertical de un módulo respecto de otro, sin necesidad de emplear conectores externos.

An adapter for a surface mount device, the adapter including an insulating body having offset first and second surfaces; a pattern of surface mount solder pads formed on the first surface; a pattern of signal carriers communicating between the first and second surfaces, each of the signal carriers being at least partially exposed in an area between the first and second surfaces and adjacent to the second surface; and a plurality of signal lines electrically coupling one or more of the surface mount solder pads with predetermined ones of the signal carriers.
Abstract:
The invention relates to a method and a device for interconnecting electronic components in three dimensions. In order to reduce the stray capacities between the connections and the shielding (304) of the device, metallized (42) grooves (40, 41) are cut into the block (3') of stacked circuits, the conductors (21) of said circuit being set back from the corresponding face (302) of the block. Said grooves cut into the connection conductors (21). The assembly is then coated with resin (303) and shielded by metallization (304). The invention is especially suitable for producing more compact three-dimensional electronic systems.
