Abstract:
Connection terminals each include: a bonding portion bonded to a pad of a substrate; a contacting portion disposed to face the bonding portion; a spring portion present between the bonding portion and the contacting portion; and an engaging portion engaged with a portion of a slit provided in a plate-like member. These constituent portions of the connection terminal are formed integrally with each other. The plate-like member has recessed portions formed at predetermined positions, and the connection terminals are electrically connected to the pads of the substrate with the bonding portions of the connection terminals being locked to the recessed portions.
Abstract:
A first circuit board (1) mounted with an electronic component (16) and a second circuit board (2) are vertically connected three-dimensionally through an interconnecting board (3) wherein the terminal portion (6) of the land electrode (5) on the interconnecting board (3) is buried in the termination material (9) of the interconnecting board (3). Consequently, the chance of peeling or cracking due to peeling stress or shearing stress acting between the upper/lower circuit boards and the land electrode by high density mounting, thermal shock or falling impact can be suppressed or buffered resulting in high reliability.
Abstract:
To provide a dielectric sheet that can be used as an elastomer connector in order to connect highly integrated circuit board and fine pitch electronic parts. The dielectric sheet (10f) comprises a first penetrating region (222c) having high permittivity, and a second penetrating region (33a) having conductivity, the regions are arranged and formed in such a way that they are alternatively interspersed in longitudinal and crosswise directions in a non-conductive sheet-shaped elastomer. The transverse thickness W2 and longitudinal thickness W5 in the first penetrating region (222c) may be arbitrarily determined. Similarly, the transverse thickness W3 and longitudinal thickness W5 in the second penetrating region (33a) may be arbitrarily determined. The dielectric sheet (10f) serves to compliment the circuit of electronic parts (for example, the printing board) to be connected thereto.

Space transformer connectors for coupling printed circuit boards and/or other electrical connections are disclosed. A scalar design of a multilayer space transformer connector allows for a variety of pad-array field connections. A conductive elastomer interface provides for repeated and consistent coupling and decoupling of the space transformer connector.

Abstract:
The invention provides methods to mass laminate and interconnect high density interconnect circuit layers fabricated through parallel processing. Invention methods employ an inside-out interconnection strategy that eliminates plating of vias and provides defect-free outer circuit layers. Conductive paste and via layers are also key features of the invention.
