Abstract:
An element (1) is mounted on a carrier (4) by removing an oxide film sufficiently. An element mounting method in which electrodes (2,3) of the element are fusion bonded to electrodes (5,6) of the carrier so that the element is mounted on the carrier, the method includes the steps of: positioning the electrodes of the element at electrodes of carrier respectively, one of the electrodes of the carrier is a striped electrode (5) in an arc shape formed on a concentric circle centering one of the electrodes of the element, and another is a center electrode (6) formed near the center location of the concentric circle; and then rubbing the striped electrode of the carrier and the electrode of the element together in a direction of the concentric circle centering the center electrode so as to fusion bond the electrodes.
Abstract:
Es wird eine elektrische Vorrichtung mit einem Trägerelement (11), insbesondere einer Leiterplatte, vorgeschlagen. Diese Vorrichtung weist zumindest eine auf dem Trägerelement (11) angeordnete Anschlussfläche (16) auf, die zur Kontaktierung eines Bauelements (50) dient. Die Öffnung ist dadurch gekennzeichnet, dass die benetzbare Anschlussfläche (16) jeweils aus zumindest zwei Teilflächen (28, 31) besteht, wobei eine der Teilflächen (28) schmaler als die andere Teilfläche (31) ist.

Abstract:
A method and system for efficiently self-aligning parts of a MEMS during manufacturing, as well as controlling distance between these parts, are disclosed. According to the invention each MEMS part comprises at least one pad that is aligned so as to form a pair of pads. In a preferred embodiment, each part comprises three pads. The pad shape of two pairs of pads is rectangular, one pair being rotated of an angle approximately equal to 90° from the other, and the pad shape of the third pair is annular. Therefore, one of the pair of pads allows alignment according to a first direction, a second pair of pads allows alignment according to a second direction, and the third pair of pads allows rotational alignment.
Abstract:
A method of making a plurality of monolithic thick film components (10) having multiple terminals (12, 14, 16, 18) comprising the steps of printing a plurality of components (10) in a wafer form forming a matrix of components, printing holes (20) in the matrix of components where two terminal ends meet thereby separating the terminals (12, 14, 16, 18) on each component, and dipping the terminal ends in a silver based thick film ink (26).
Abstract:
A plurality of plate-like circuit component carrier packages (71) are stacked adjacent one to another with the flat faces (72, 74) thereof in contact to form a carrier package assembly (40). Each carrier package houses one or more electrical circuit component (110) coupled to electrical contacts (84, 86) on the flat faces and electrical contacts (98) or upstanding pins (424, 436) on the sides. These cooperate with those of adjacent carrier packages to electrically interconnect with the circuit components therein. A flexible, printed circuit board (50) having an array of contact sites (52) selectively interconnected by printed routing traces (54) is wrapped around the carrier package assembly. The ends of the carrier package assembly are fitted with supporting and electrically interconnecting connector blocks (22, 16). Plural carrier package assemblies are interconnectable directly, by nesting, or through intermediate connecting structures.

Abstract:
The invention relates to a device for soldering the components on printed circuits, of the type for carrying out so-called wavesoldering. As claimed in the invention, the printed circuits are fed in a feed direction that coincides with the machine's main axis, and the soldering wave is produced in such a manner that, on the one hand, its main dimension is oblique in relation to the said feed direction and/or, on the other hand, it is subject to an orbital or alternative movement in the direction of its said main dimension.
