Abstract:
A flex-rigid wiring board includes a flexible board including a flexible substrate and a conductor pattern formed over the flexible substrate, a non-flexible substrate disposed adjacent to the flexible board, an insulating layer including an inorganic material and covering the flexible board and the non-flexible substrate, the insulating layer exposing at least one portion of the flexible board, a conductor pattern formed on the insulating layer, and a plating layer connecting the conductor pattern of the flexible board and the conductor pattern on the insulating layer.
Abstract:
A circuit board includes a large scale logic device and at least one outrigger device wherein signals having a transmission delay budget that exceed a threshold value are produced to the outrigger device for coupling to circuit devices of the circuit board that are external to the large scale logic device. One embodiment of the invention comprises a plurality of outrigger devices that communicate with the large scale logic device by way of parallel data buses, as well as multi-gigabit transceiver data lines. Logic within the outrigger devices is generally limited to signal routing and transmission logic. The large scale logic device further comprises logic to transmit and receive signals to and from the outrigger devices in a way that is transparent to internal logic of the large scale logic device.
Abstract:
The invention is directed to a method of bonding a hermetically sealed electronics package to an electrode or a flexible circuit and the resulting electronics package that is suitable for implantation in living tissue, such as for a retinal or cortical electrode array to enable restoration of sight to certain non-sighted individuals. The hermetically sealed electronics package is directly bonded to the flex circuit or electrode by electroplating a biocompatible material, such as platinum or gold, effectively forming a plated rivet-shaped connection, which bonds the flex circuit to the electronics package. The resulting electronic device is biocompatible and is suitable for long-term implantation in living tissue.
Abstract:
A laminating step includes a second step of laminating a second insulation layer on a conductive pattern last formed at a first step, roughening the surface of the laminated second insulation layer excluding a desired area, and forming a conductive layer on at least the desired area of the surface of the second insulation layer, and a processing step includes a removing step of removing an upper part of the area higher than the second insulation layer on the substrate obtained at the laminating step, and an exposing step of exposing a part of the area of a conductive pattern adjacent to the lower side of the second insulation layer.

Abstract:
An electrical connector assembly (1) includes an LGA connector (2) having a metal clip (25) and a pick up cap (3). The pick up cap has a planar body (30) forming a plane top surface (300). Several holes (302, 303, 309) are defined in the planar body. When the pick up cap is engagingly mounted onto a top portion of the connector, the holes are in communication with a window (258) of the clip. A vacuum suction device can engage the top surface of the pick up cap to move the connector assembly to a desired location on a PCB. When curing adhesive film at high temperature, heated air can flow through the holes to a bottom portion of the connector. Reliable electrical connection between the contacts of the connector and the metal contact pads of the PCB is subsequently produced in a wave solder machine or drag soldering equipment.

Abstract:
A small package is provided for a flash EEPROM memory. The small package uses terminals which are part of a bottom conductive layer of a circuit board. In this manner, the final package can be quite thin. The circuit board can be connected to the integrated circuits and passive devices and can be encapsulated in plastic or glued to a plastic cover. In this manner, a thin and relatively inexpensive package can be formed. Additionally, the circuit board can have testing connections which can be removed before forming the final package.
