Abstract:
A magnetic head suspension assembly, wherein a wiring member for connecting a magnetic head element with a read/write amplifier circuit board is integrally formed with the suspension for supporting the magnetic head element. The suspension is equipped integrally with a circuit wiring pattern via a flexible insulating base material. The flexible insulating base material is made as wide as the circuit wiring pattern. The top surface of the circuit wiring pattern has a surface protecting layer which is wider than the circuit wiring pattern.
Abstract:
A multilayer printed circuit board comprising conducting layers of a first material and conducting layers of a second material includes noncorrosive low resistance electrical contacts between conducting layers of the first and second material. The noncorrosive low resistance contacts allow the use of light weight conducting materials for particular layers of the circuit board to produce a light weight multilayer circuit board.
Abstract:
A method of manufacturing a multilayer electronic component having one major surface which can be completely used as a mounting surface for another electronic component to form a composite component includes the steps of forming a groove in the mother laminate along a cutting line, forming external electrodes on side surfaces of the groove and then dividing the mother laminate along the cutting line to divide the groove thereby forming a plurality of multilayer electronic components that are independent of each other. The method of forming the electronic components allows for measuring electrical characteristics of the individual multilayer electronic components while the components are still part of the mother laminate.
Abstract:
A process for the formation of side metallization in ceramic sheets is provided by the present invention. The process includes the steps of forming a via within the ceramic sheet and splitting the via to expose the metallization contained therein. The process is particularly useful for forming wraparound metallization on feedthroughs utilized in hermetic packages.
Abstract:
In a circuit board wherein a plurality of leads 21 electrically independent of one another protrude from a base member 10, and the respective leads 21 are electrically connected with connection portions 31 of an electronic component 30 mounted on the base member 10; an electronic component mounting circuit board 100 characerized in that internal connection portions 22 are unitarily formed on inner sides of metal members 20 constructing said respective leads 21, that the base members 10 are integrally disposed on both surfaces of said internal connection portions 22, that the electronic components 30 are mounted on said base members 10, and that said electronic components 30 and said internal connection portions 22 are electrically connected. Thus, according to the present invention, it is possible to provide a simply constructed electronic component mounting circuit board which facilitates the design of circuits, which dispenses with the resin molding of the connected portions between the electronic components and the respective leads and affords excellent connection reliability, which can readily form a heat radiating structure, and in which the thermal matching with the electronic components is excellent.
Abstract:
An electrooptical cell has electrical connection means between electrodes and a control unit which comprise a contact block of a synthetic adhesive material having conducting particles applied on the edge of each plate in contact zones which are provided flush with said edge, the contact block constituting both the electrical connection and the mechanical bond with at least one other element of said connection.
Abstract:
Internal printed circuits on multi-layer or laminated circuit boards are electrically connected to resistors, capacitors and the like circuit components by connector pins that abut the internal printed circuit at an end extremity and are frictionally held in a hole in the board that to the exterior of the board only at the component mounting side of the board. The pins have a shoulder that limits the penetration during assembly procedures and another hole in which the lead wire of the circuit component is frictionally engaged.
Abstract:
Printed circuit boards (PCBs) may include embedded lateral connectors. The embedded lateral connectors may be configured to enable components to quickly couple to or plug into a PCB, thus saving time to form connections. The embedded lateral connectors may also reduce weight and/or size by avoiding need for bulky tradition collections with conventional components (e.g., solders, external pin connectors, etc.). The connectors may include male connectors, female connectors, and/or mounting connectors. The connectors may be configured to connect multiple PCBs together, such as using a stacked configuration, which may enable reducing a volume of space needed in a housing for the PCBs.
