Abstract:
The invention relates to a method for connecting two film cable ends. A metal strip (4), which is tin-plated with a solder, is placed transversally across the conductor strips (2) between the two film cable ends (1), the latter are pressed together with the interposed tin-plated metal strip, the metal strip is supplied with current and heated until the solder of the metal strip melts and fuses with the conductor strips of the film cable. Once the solder connection has been made, the metal strip is severed in the intermediate spaces between two neighbouring conductor strips.
Abstract:
A thermocurable electroconductive adhesive sheet which is able to make an electric connection having mechanical, thermal and electric stability, and low resistance, produced by a simple and easy process is provided.
Abstract:
When an adhesive is applied on a metallic wiring, the metal forming the metallic wiring film dissolutes as ions into the adhesive with time. If the adhesive is based on a polyester resin and placed in an environment of high temperature or high temperature and high humidity, adhesion and insulation are deteriorated by the free metallic ions. However, adhesives of the present invention contain a cation scavenger to scavenge the free metallic ions in the adhesives. Thus, highly durable flat cables can be obtained. Thus, flat cables with reduced loss in adhesive strength and insulation are provided.
Abstract:
Bei einer derartigen Sensoranordnung, beispielsweise zur Abtastung einer Meßteilung bei einer Positionsmeßeinrichtung, weist ein Substrat (2) die Sensoren (5) und in integrierter Form mit diesen Sensoren (5) elektrisch verbundene Leiterbahnen (6) eines ersten Teils eines elektrischen Verbindungselements (7) auf. Diese Leiterbahnen (6) überragen das Substrat (2) in einen zweiten Teil des elektrischen Verbindungselements (7) freitragend und werden an ihren freien Enden (13) mit Kontaktstellen einer Leiterplatte durch Lötung verbunden.
Abstract:
The invention refers to a tip to mount or repair printed circuit board lines, designed as an accessory to the electronic circuit wiring device described in Patented Invention 538.302. This tip includes a means of attachment to this device intended to substitute the latter's classic tip, at the free end of which device the flat tip itself is located whose section is equal to that of a thin band of tin coated copper designed to be the wiring element to obtain or repair circuit lines, fed by a reel attached to the device.

Abstract:
Disclosed is a method for repairing opens (12) in thin film conductor lines (11) on a substrate (10), preferably a multilayered ceramic substrate. An unpatterned repair metal film (20) is placed over a general area of open defects (12) in conductive lines (11) on a substrate (10). Preferably, this metal is placed over the conductive lines and opens therein by decal transfer. The assembly is then heated to cause diffusion bonding between the repair metal (20) and conductive lines (11), but not between the repair metal (20) and substrate (10). After diffusion bonding, the structure has metal bridges formed across any open defects covered by the repair film and also between adjacent conductive lines. The area of repair is then subjected to ultrasonic energy in a liquid ambient for a time at least long enough to remove metal bridges between adjacent conductive lines, but less than that required to remove repair metal bridges over the opens in the conductive lines. The resultant structure has metal bridges spanning opens in the conductive lines, and no metal bridges between adjacent conductive lines.
