Abstract:
A printed wiring board includes a plurality of conductor plates that includes at least one conductor plate that is used as a lead for electrical connection with an external circuit, the conductor plates being separated spatially from one another; an insulating layer formed on or across the conductor plates or both on and across the conductor plates; and a plurality of wiring patterns formed on the insulating layer. At least one of the conductor plates is electrically connected with at least one of the wiring patterns through a via-hole.
Abstract:
A box unit is a housing having a space for containing a circuit board therein. Bus bars are insert-molded in a resin body of the box. A metal shield plate is insert-molded around the entire periphery of the box and outside the bus bars. As a result, the box has a shield and is reduced in size compared with a metal box.
Abstract:
The invention relates to a conductive portion device (300) having a plurality of independent conductive portions and attached to an attaching base member (360). The device includes a film (310) and a plurality of conductive materials (321, 322 and 323) to be attached to the film (310), which constitute the respective independent conductive portions, and the device further has holes (302a to 302d) corresponding to protrusions (362a to 362d) formed on the attaching base member (360).
Abstract:
A solderless electrical interconnection is made using electrically conductive hook fasteners (15) that are embedded in a substrate (12). The upper part (20) of the fastener is exposed on the top side of the substrate, the central part (22) is embedded within the substrate itself, and the lower or hook portion (17) of the fastener protrudes from the bottom side of the substrate. Electrically conductive pathways (30), defined on the top side of the substrate, make contact with the exposed upper part of the hook fastener. The electrically conductive runners on the top side have a continuous signal path through the substrate to the bottom side of the substrate via the electrically conductive hook fastener. The hook fastener (15) is engaged to electrically conductive loop fasteners (60) on a second substrate (70) in order to create a solderless electrical interconnection and mechanical interlocking between the two substrates.
Abstract:
A thick film hybrid arrangement has a plurality of ceramic foils provided with conductor paths and superimposed over one another, a support for supporting the ceramic foils, and a plurality of thin metal lugs located between the ceramic foils for contacting the conducting paths. The metal lugs extend outwardly beyond at least the ceramics foils so as to form outer contacts.
Abstract:
An electrically connectable module is manufactured from a substrate of an electrically insulating polymer matrix doped with an electrically insulating fibrous filler capable of heat conversion to an electrically conductive fibrous filler to form a fiber-doped substrate. One end of an electrical connector is embedded in the fiber-doped substrate to locate the one end adjacent the surface of the substrate while exposing an opposite end of the electrical connector. The surface of the fiber-doped substrate is locally heated preferably with a laser to form a conductive trace by the in-situ heat conversion of the electrically insulating fibrous filler, the localized heating including the one end of the electrical connector to electrically connect the electrical connector to the conductive trace. In another embodiment, a conductive material is electrodeposited on the conductive trace by applying a voltage to the opposite end of the electrical connector. The substrate is molded into a desired shape to form the module, and a plurality of electrical connectors can be embedded into the substrate in any one of several different standardized arrangements.
Abstract:
A module board has a supporting plate and slender lead pins having their first portions arranged substantially in parallel with one another on a plane substantially coplanar with the supporting plate. The supporting plate and the first portions of the slender lead pins are sandwiched between electrically insulating layer members. The supporting plate and the first portions of the lead pins are isolated from one another with an electrically insulating material between the pair of electrically insulating layer members. Second portions of the lead pins protrude from the pair of electrically insulating layer members. Through holes are provided one for each of the lead pins and through hole conductors are formed on the inner walls of the through holes. Each of the through hole conductors passes through the pair of electrically insulating layer members and the first portion of its associated one of the lead pins and is in electrical connection with a pattern of electrical conductors provided on the pair of electrically insulating layer members, thereby fixing its associated lead pin to the board and electrically connecting its associated lead pin to the pattern of electrical conductors.
Abstract:
Interplane connectors (vias) between circuit layers are fabricated by providing a metal base plate with the desired connectors thereon, forming the connectors at right angles to the base plate and embedding the connectors in a plastic matrix. The base plate is then removed, leaving the plastic with the connectors embedded therein at the desired locations.
