Abstract:
The present invention provides glass fiber strands impregnated with non-abrasive solid particles which provide interstitial spaces of at least 3 micrometers between adjacent fibers within a strand which are useful for reinforcing composites.
Abstract:
A gas discharge display device comprising a front side substrate having a plurality of first electrodes and a back side substrate having a plurality of second electrodes, wherein at least said first electrodes or second electrodes are formed by wet etching using a resist made of an inorganic material, is excellent in the ability to suppress the breakage of wiring in electrodes.
Abstract:
The specification describes of multilevel printed circuit boards and a process for their manufacture in which capacitors and other passive components are buried between levels of the multilevel board. The capacitor in the multilevel structure is designed so that access is conveniently provided to connect from the parallel plate electrodes of the interlevel capacitor to the board surface or to another board level using plated through hole interconnects.
Abstract:
Selon un mode de réalisation de l'invention, les composants électroniques discrets ou intégrés, sont encapsulés chacun dans un boîtier, par exemple plastique; les boîtiers sont ensuite montés sur une carte de circuit imprimé, par exemple époxy. L'ensemble composants et carte est recouvert d'une première couche relativement épaisse, constituée par un composé organique et assurant une fonction de nivellement, puis d'une couche telle qu'un composé métallique minéral, ayant pour fonction d'assurer l'herméticité de l'ensemble.
Abstract:
In the present invention, a thick resist layer is formed on a thin metal film and the resist layer is dry-etched by using a Si0 2 mask formed selectively on the resist layer, and the thick wiring metal layer is formed by plating method with using the dry-etched resist layer having perpendicular side wall as a mask, thereby to form a low resistance and fine pattern wiring metal layer.
Abstract:
Die Erfindung betrifft ein Substrat zur Aufnahme zumindest eines Bauelements (4), insbesondere eines Leistungshalbleiters, bei dem ein Substratkörper (1) auf zumindest einer Vorder- und/oder einer gegenüberliegenden Rückseite mit einer elektrisch leitfähigen Schicht (3, 3a, 3b) versehen ist. Zur Verbesserung der Wärmeableitung von der elektrisch leitfähigen Schicht (3, 3a, 3b) wird erfindungsgemäß vorgeschlagen, dass zwischen dem Substratkörper (1) und der elektrisch leitfähigen Schicht (3, 3a, 3b) eine elektrisch isolierende Verbindungsschicht (2, 2a, 2b) vorgesehen ist, welche eine aus einem präkeramischen Polymer gebildete duroplastische Matrix aufweist.
Abstract:
A capacitor and a method of manufacturing the capacitor. The capacitor may include a board, a polymer layer formed on one side of the board, a circuit pattern selectively formed over the polymer layer, and a titania nanosheet corresponding with the circuit pattern. Embodiments of the invention can provide flatness in the board, and allows the copper of the board to maintain its functionality as an electrode while increasing the adhesion to the titania nanosheet. The titania nanosheet may thus be implemented on a patterned board in a desired shape, number of layers, and thickness.
