Abstract:
An ink contains particles containing metal that reacts during sintering to produce an electrically conductive line or area having a diffusivity that is less than the diffusivity of the metal before the reaction. Resulting electronic circuits therefore exhibit longer useful lives, compared to conventionally inkjet printed circuits.
Abstract:
A sheet-fed system designed to print multilayer PCBs is introduced. The system consists of four main blocks; a drilling station, a patterning station, a stacking/bonding station, and a sintering zone. The substrate PCB is shuttled between these various stations, to have vias drilled, to be attached to stacks of previously-processed layers, to be covered with conductive paths by means of the aforementioned ink, and to have the ink sintered under a controlled temperature and atmosphere. Patterning is accomplished by means of a novel two-step method involving both high-temperature conductive elements, low- temperature conductive elements, and flux. Two such compositions are successively applied and individually sintered to form a single conductive path; the second application serves to fill the porosities of the first layer. By this method, a highly-conductive trace is obtained without requiring high temperatures, which in turn allows use of common substrates including polymers.
Abstract:
A conductive composition includes a mono- acid hybrid that includes an unprotected, single reactive group. The mono-acid hybrid may include substantially non- reactive groups elsewhere such that the mono-acid hybrid is functional as a chain terminator. Methods and devices using the compositions are also disclosed.
Abstract:
Mit dem Vordringen der Leistungselektronik in immer höhere Spannungsbereiche verschärfen sich die Forderungen hinsichtlich hoher Isolationsspannungen und großer Teilentladungsfestigkeit. Deshalb wird ein Bauteil (1) mit einem Keramikkörper (2) vorgeschlagen, der in mindestens einem Bereich auf seiner Oberfläche (3, 4) mit einer Metallisierung (5, 6; 11) bedeckt ist und wobei der Keramikkörper (2) räumlich strukturiert (7) ist, und die Teilentladungsfestigkeit zwischen mindestens zwei Schichten einer Metallisierung (5, 6) aus gleichartigen oder unterschiedlichen Werkstoffen sowie zwischen der Schicht (5; 11) einer Metallisierung und der Keramik
Abstract:
An antenna includes a first substrate, a first pattern, a second substrate, a second pattern, and an anisotropic conductive material. The first substrate has an insulating surface. The first pattern is formed over the insulating surface of the first substrate, and made of a conductive material. The second substrate is provided so as to face the surface over which the first pattern of the first substrate is formed and has an insulating surface. The second pattern is formed over the insulating surface facing the first substrate of the second substrate, and made of a conductive material. The anisotropic conductive material electrically connects the first pattern and the second pattern. The whole region of the first pattern overlaps with the second pattern with the anisotropic conductive material interposed therebetween.
