In one electronic device package, the semiconductor die is electrically connected to the interposer with wire bonds attached to a routing layer of the interposer. In another electronic device package, the semiconductor die is electrically connected to the interposer by bonding the semiconductor die to the flexible solder pad elements of the interposer in a flip-chip configuration. A computer system incorporating an electronic device package with an interposer according to the present invention is also disclosed.
Abstract:
A method for manufacturing a multilayer ceramic board prevents damage to a wiring conductor formed on the surface of a multilayer ceramic board fabricated via a non-contraction process. On at least one principal surface of a layered body made up of a plurality of board ceramic green sheets including ceramic material powder, contraction prevention green sheets including inorganic material powder which is not sintered at the baking temperature of the board ceramic green sheet are arranged such that along at least a portion of the outer circumference of the principal surface, the portion and a nearby portion thereof are exposed to form a compound layered body, the compound layered body is baked under a condition in which the ceramic material powder is sintered, and the inorganic material powder is not sintered, following which the contraction prevention green sheets are removed. With a multilayer ceramic board, protruding portions are formed along at least a portion of the outer circumference of a principal surface.
Abstract:
A pedestal connector that incorporates one or more grouped element channel link transmission lines is seen to have a dielectric body and two opposing contact ends that are intended to contact opposing contacts or traces. The dielectric body has an S-shaped configuration such that the transmission lines supported thereon make at least one change in direction, thereby permitting the use of such connector to interconnect elements lying in two different planes. The transmission lines include slots that extend within the frame and which define opposing, conductive surfaces formed on the dielectric body which are separated by an intervening air gap.

Abstract:
A wiring circuit board and a method of producing the same are provided in which a desired pattern of wiring is provided at higher density while permitting no overflow from the grooves of an electroless plating catalyst containing solution and an electric conductor forming liquid such as silver ink. The pattern of electric conductor is deposited by applying the electric conductor forming liquid into the grooves provided in a substrate and distributing the same along the grooves with the action of capillarity. The method starts with patterning the grooves in the surface of the substrate (S1), applying the electric conductor forming liquid into the grooves (S2), and coating the surface of the substrate with a layer of repellent liquid which is lower in the affinity with the electric conductor forming liquid (S3). This is followed by cleaning at least the grooves (S4) and then filling the grooves with the electric conductor forming liquid once again (S5). The electric conductor forming liquid applied into the grooves is then distributed throughout the grooves by the action of capillarity. When silver ink is used, the pattern of electric conductor is produced by repeating an action of applying and drying a number of times. Alternatively, the patter of electric conductor can be produced by an electroless plating technique or a combination of an electroless plating technique and an electro-plating technique for separating an electrical conductive material form the electric conductor forming liquid.
