Abstract: In a dielectric filter to be mounted on a printed circuit board, a conductive layer (x) formed on the surface of a dielectric substrate (1) includes an electroless copper-plated layer (m) formed on the surface of the substrate, and a conductive covering layer (n) having good dielectric conductivity and good solder wettability and formed on the surface of the electroless copper-plated layer (m). In place of the conductive covering layer (n) or in addition to the conductive covering layer (n), there is provided a protective synthetic resin layer (p) which covers the electroless copper-plated layer (m) or the conductive covering layer (n) and which vanishes upon exposure to heat of molten solder (25). Even when the conductive layer (x) is formed by electroless copper-plating, the conductive layer (x) is free from stain. Moreover, a terminal portion of the conductive layer (x) formed on the surface of the dielectric filter (1) can be soldered to a conductive path formed on a printed circuit board to thereby establish electric connection therebetween.

Abstract: Resilient contact structures (430) are mounted directly to bond pads (410) on semiconductor dies (402a, 402b), prior to the dies (402a, 402b) being singulated (separated) from a semiconductor wafer. This enables the semiconductor dies (402a, 402b) to be exercised (e.g., tested and/or burned-in) by connecting to the semiconductor dies (702, 704) with a circuit board (710) or the like having a plurality of terminals (712) disposed on a surface thereof. Subsequently, the semiconductor dies (402a, 402b) may be singulated from the semiconductor wafer, whereupon the same resilient contact structures (430) can be used to effect interconnections between the semiconductor dies and other electronic components (such as wiring substrates, semiconductor packages, etc.). Using the all-metallic composite interconnection elements (430) of the present invention as the resilient contact structures, burn-in (792) can be performed at temperatures of at least 150 °C, and can be completed in less than 60 minutes.

Abstract: A connection structure between lead frames (3) and a base plate (1) of aluminum nitride, to be applied as a connection structure between components of a semiconductor apparatus, comprises the base plate formed of a sintered body of aluminum nitride on which a semiconductor device is to be mounted, the lead frames including, as a main material, iron alloy containing nickel in 29 wt.% and cobalt in 17 wt.%, and silver solder (9) for joining the base plate and the lead frames. A surface of the lead frame to be joined to the base plate is formed of oxygen-free copper of a high plastic deformativity to relieve, by plastic deformation of itself, a thermal stress caused by a difference between a thermal expansion coefficient of the base plate and that of the lead frame in a cooling process at the time of soldering. Preferably, only a portion of each lead frame (3) to be joined to the base plate comprises an inner layer portion of iron alloy containing nickel in 29 wt.% and cobalt in 17 wt.%, and an outer layer portion of oxygen-free copper.

Abstract: Procédé et dispositif d'interconnexion de circuits électroniques (104) utilisant de l'or recuit complet presque pur qui est comprimé mécaniquement à l'intérieur de trous traversants dorés (111). Cette invention permet de fixer des dés de circuits intégrés (104) directement sur les cartes de circuit (110) en soudant des fils en or en forme de perles (101) sur les blocs de soudage (105) des dés de circuits intégrés (104) de manière essentiellement perpendiculaire aux surfaces des dés (104) et en introduisant les conducteurs en or (101) dans les trous traversants dorés (111) des cartes de circuit (110) qui assurent une connexion mécanique et électrique une fois que les conducteurs (101) sont comprimés dans les trous traversants dorés (111). La présente invention s'applique également lors de l'interconnexion d'assemblages de cartes de circuit en sandwich (200), où des fils conducteurs en or mou sont introduits dans des trous traversants dorés alignés axialement dans les cartes de circuits (212, 214, 216, 217, 219, 221) et comprimés de sorte que lesdits fils conducteurs en or se déforment à l'intérieur des trous traversants dorés, établissant ainsi un contact électrique entre les cartes de circuits (212, 214, 216, 217, 219, 221).

Abstract: A monolithic capacitor chip (10') comprises a body formed of stacked, alternately arranged layers of dielectric material (16) and metallic electrode material (18'), altemate electrodes extending to opposite end faces of the body, and a noncompliant metalized layer (20', 22') on each of the opposite end faces electrically contacting the electrodes (18') extending thereto. Each of the noncompliant metalized layers (20', 22) is provided with a compliant coating (32,34) of an alloy preferably comprising more than 90 % lead. A metallic layer (36, 38) is disposed over the surface of each of the compliant coatings (32, 34), the melting point of the metallic layers (36, 38) being greater than that of the compliant coating (32, 34). The metallic layer (36, 38) preferably consists of a layer of copper or nickel plating, the surface of which is plated with an oxidation resistant metal such as tin, gold, or the like.
