Abstract:
A hybrid circuit board includes a first circuit board and a second circuit boards. The first circuit board includes a first body having a slot, and a first circuit pattern formed on the first body and extended to the slot. The second circuit board includes a second body, a protruding portion, a second circuit pattern, and a separating member. The protruding portion extends from the second body. The protruding portion is inserted into the slot of the first circuit board to combine the second circuit board to the first circuit board. The second circuit pattern is formed on the second body to be extended to the protruding portion, so that the second circuit pattern is electrically connected to the first circuit pattern of the first circuit board. The separating member is disposed between the second body and the protruding portion to separate the protruding portion from the second body.
Abstract:
A rigid-flexible circuit board with two rigid areas and one flexible area, with a rigid individual layer which is copper-clad on one side, with an adhesive medium and with a copper foil, the adhesive medium having recesses in the flexible area. The rigid-flexible circuit board can be produced especially easily and economically in that at least in the rigid area there is no flexible individual layer, especially no polyimide film, between the adhesive medium and the copper foil.

A printed circuit board includes a substrate and an inspection piece part having a solder part provided on a surface of the substrate to be inspected by an inspecting apparatus. Thus, the printed circuit board and an inspected unit can efficiently be inspected without being disassembled and damaged.
Abstract:
A method for producing a multilayer printed wiring board includes an inner layer formation step of forming an inner layer pattern in a core substrate divided corresponding to a flexible portion that is made bendable and a hard portion that is made rigid, and an outer layer formation step of forming an outer layer such that an outer layer material that covers the core substrate is caused to make contact at the hard portion, and an outer layer pattern formation step of forming an outer layer pattern in the surface of the outer layer material, and a removal step of removing a covering portion that is the outer layer material and is covering the flexible portion, and an outer shape formation step of forming the outer shape of a layered substrate formed via the removal step. Also, an inner layer protection pattern is formed in the periphery of the flexible portion before the outer layer formation step, and the method is provided with a step of severing the periphery of the covering portion by irradiating a laser beam on the outer layer material that corresponds to the inner layer protection pattern before the removal step.
Abstract:
A method for manufacturing a mid-plane. a multi-layer board having a connection assembly is provided and a dielectric layer with a channel formed therein to define a perimeter of a connector area is provided. The dielectric layer is bonded to the multi-layer board such that the connector area overlaps the part of the connection assembly of the multi-layer board. At least a portion of the connector area in the dielectric layer is removed to expose the connection assembly of the multi-layer board. A rigid multilayer is also disclosed. The rigid multilayer includes a multi-layer board and a dielectric layer. The multi-layer board has a connection assembly. The dielectric layer has a channel formed therein to define a perimeter of a connector area. The dielectric layer is bonded to the multi-layer board such that the connector area overlaps the connection assembly of the multi-layer board. The connector area can then be removed such as by depth controlled routing. As will be understood by one skilled in the art, the depth tolerance is not critical because the dielectric layer is pre-formed with the channel prior to formation of the rigid multi-layer.

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 printed wiring substrate has a circuit wiring area that has a circuit wiring pattern formed thereon and a peripheral area that is placed in the periphery of the circuit wiring area. The peripheral area has a property display area that is provided with a display location specified in association with a property for displaying a property of the printed wiring substrate. The property can be something that indicates an attribute of the printed wiring substrate such as production lot information, information on an inspection result of an electrical property (such as short-circuit defect, disconnection defect and wiring resistance defect), information on a visual inspection result (such as plating defect and silk screen defect), and the like.
Abstract:
To provide an electronic apparatus having a tuner circuit board that can prevent undesirable radiation, is laid out to allow a hybrid tuner designed both for digital broadcasting and analog broadcasting to be mounted. On a tuner circuit board 30 having a tuner section 130 on which a vertical-type tuner 41 and a horizontal-type tuner 42 can interchangeably mounted, an IF block 142 and an MPEG IC 140 are disposed at a distance from a power supply section 150, a grounding section 170 extending from the tuner section 130 is provided. In the case of the vertical-type tuner 41, the grounding section 170 is separated off by a tear-off line 173. In the case of the horizontal-type tuner 42, the grounding section 170 is not separated off so that the grounding section 170 reduces the effect of an undesirable radiation emitted by the mounted horizontal-type tuner 42.

Abstract:
A method and structure are provided for creating printed circuit boards with stepped thickness. A non-laminating breakaway material layer is selectively placed between layers of the printed circuit board. A perimeter portion of the printed circuit board near the breakaway material layer is scored. Then the breakaway material layer and adjacent layers between the perimeter of the printed circuit board are removed.
