Abstract:
A mounting substrate includes a through-hole 13 formed in a substrate 10, a first land part 21, a second land part 31, a first component attaching part 22, a second component attaching part 32, a conductive layer 14, and a filling member 15 filled into a part of the through-hole 13. A shortest distance allowable value L0 from the center of the first land part 21 to a component 51 is determined on the basis of the volume Vh of a part of the through-hole 15 positioned above a top surface of the filling member 15 on the side of the first land part 21, the length L1 of the component 51 to be mounted to the first component attaching part 22, and the maximum allowable value of the inclination of the component 51 to be mounted to the first component attaching part 22 relative to the first surface 11 of the substrate 10.
Abstract:
An engagement structure for preventing the separation of a resin layer is formed in a contact surface of an insulating substrate in a connecting component, the contact surface being in contact with the resin layer. The resin layer engages with the engagement structure in the contact surface in the insulating substrate in contact with the resin layer, the contact surface forming the side surface of the connecting component.

A tape package includes a base substrate including a signal transmitting area and a protruding area protruded from the signal transmitting area, an integrated circuit chip mounted on the base substrate, and a lead line disposed on the base substrate and including a first portion electrically connected with the integrated circuit chip, a second portion electrically connected with the first portion and extending in a first direction, and a third portion electrically connected with the second portion and extending in a second direction crossing the first direction.
Abstract:
A multi-piece-array formed by laminating a plurality of ceramic layers includes: a product region where a plurality of wiring board portions having a rectangular shape in plan view and including cavities are arranged in matrix; a redundant portion that is positioned along a periphery of the product region; and dividing grooves that are formed on a front surface and/or a back surface along a boundary between the wiring board portions and a boundary between the wiring board portion and the redundant portion. A deepest portion of the dividing groove has an arc shape and the dividing groove includes a middle portion, and a width of the deepest portion is greater than a width of the groove inlet and a width of the middle portion is equal to or less than the width of the groove inlet.
Abstract:
Connector inserts and other structures that have a high signal integrity and low insertion loss, are reliable, and are readily manufactured. One example may provide a connector insert formed primarily using a printed circuit board. Contacts on the connector insert may be akin to contacts on a printed circuit board and they may connect to traces having matched impedances on the printed circuit board in order to improve signal integrity and reduce insertion loss. The printed circuit board may be manufactured in a manner for increased reliability. Plating, solder block, and other manufacturing steps that are native to printed circuit board manufacturing may be employed to improve manufacturability. Specialized tools that may provide a chamfered edge on the connector inserts may be employed.
