Abstract:
A method is for packaging a first device having a first major surface and a second major surface. An encapsulant is formed over a second major surface of the first device and around sides of the first device. This leaves the first major surface of the first device exposed. A first dielectric layer is formed over the first major surface of the first device. a side contact interface is formed having at least a portion over the first dielectric layer. The encapsulant is cut to form a plurality of sides of encapsulant. A portion of the encapsulant is removed along a first side of the plurality of sides to expose a portion of the side contact interface along the first side of the plurality of sides.
Abstract:
A laminated ceramic substrate includes a side electrode in which a side edge electrode layer formed on a side edge portion of a ceramic layer overlaps with and connects to a side edge electrode layer formed on a side edge portion of another ceramic layer directly above and/or directly below the former ceramic layer. The side edge electrode layer includes a parallel wall unexposed and approximately parallel to a side surface of the laminated ceramic substrate and a perpendicular wall approximately perpendicular to the side surface of the laminated ceramic substrate. A length La of the parallel wall and a depth Lb of the parallel wall from the side surface of the laminated ceramic substrate have a relationship of La>Lb.

A local portion of the anisotropic conductive member (89) corresponding to the step difference has a step shape that is capable of contacting with the step difference. A laminate comprising respective wiring boards (79, 87) and the anisotropic conductive member disposed therebetween is pressed and held in a lamination direction.
Abstract:
In a conventional wiring board, it is not possible to effectively attract electric charges provided by a charged body to a side surface of a wiring board and, therefore, it cannot be said that sufficient measures against static electricity have been taken for the wiring board. A wiring board including: an insulating layer (L2); a conductive layer (Lc2) overlaid on the insulating layer (L2); and an insulating layer (L1) overlaid oh the conductive layer (Lc2), wherein the conductive layer (Lc2) is connected to a ground potential node and is configured inclusive of a plane part (20) formed planar within the plane of the wiring board (SUB) and a plurality of protruding parts (21) extending from the plane part (20) toward the side faces of the wiring board (SUB), protruding faces (22) forming the front edges of the protruding parts (21) are exposed at the side faces of the wiring board (SUB), and thus a plurality of the protruding faces 22 are disposed at the side faces of the wiring board (SUB).

Multilayer expansion card for connecting an apparatus or device to an electronic apparatus, particularly for association to a mother card of a Personal Computer. The card comprises a first part, intended principally for connection, having a thickness coherent with the requirements of size for connection to the standard slots of the mother card, and a second part, intended principally for the management of the card functions and for processing, and hence the electronics, having a greater thickness with respect to the first part in order to contain a correspondingly greater number of layers intended for the management of a high density of electronic-type signals.
Abstract:
A circuit board includes an electrically conductive sheet having an insulative coating surrounding the conductive sheet, with a surface of the insulative coating around an edge of the conductive sheet having an arcuate or rounded shape. At least one electrical conductor is conformally deposited on at least the rounded insulative coating around the edge of the conductive sheet and defined via photolithographic and metallization techniques. Each electrical conductor on the insulative coating thereon around the edge of the conductive sheet conforms to the arcuate or rounded shape of the insulative coating and, therefore, has an arcuate or rounded shape.
