Abstract:
Die Erfindung betrifft eine elektrische Verbindung zwischen einer Leiterbahn (12) einer Leiterplatte (14) und einem Kontaktstift (16) einer elektrischen oder elektronischen Komponente. Um eine derartige Leiterplattenkontaktierung mit hoher Prozesssicherheit und besonders zuverlässig bereitzustellen, ist gemäß der Erfindung vorgesehen, dass eine elektrisch leitfähige Hülse (20) in eine Aussparung der Leiterplatte (14) eingepresst ist und in elektrischer Verbindung zur Leiterbahn (12) steht und dass der Kontaktstift (16) in die Hülse (20) eingesteckt und mit der Hülse verschweißt ist.
Abstract:
A surface mountable miniature incandescent lamp assembly has an elongated substantially cylindrical glass envelope (20) wherein a filament (22) is contained in contact with metal members (26) and (36) having glass-to-metal seals with the glass envelope (20). A substantial portion of the outer surface of the glass envelope (20) is coated with a light reflective metal coating (50), with a non-coated elongated window (52) transparent to light being left on the surface. The metal members (26) and (36) extend axially to the outside from the envelope and, when mounted to a circuit board provide electric contact for the lamp. At least one of the end members includes a unique surface feature, such as a flat portion (54) of an otherwise cylindrical surface, which is directionally coupled relative to the window (52) of the glass envelope (20) and which acts as a key or indexing surface for mounting the lamp assembly to the receiving surface (circuit board) with the window (52) disposed in the desired direction.
Abstract:
A contact plug may be wave soldered in a preferably sealed electric component, although the original core cannot be soldered, at least not with sufficient reliability. An electrically conductive contact plug (S with H or with I) for conducting current and/or voltage to/from the electric connection of a component (E) is secured by an insulator (G), for example glass (G), within a passage in a support (K), for example a protecting housing (K) of the component (E), and contains on its surface a metal capable of being soldered with a solder paint, for example soft solder, at least on the spot (on H or I) where it can be soldered to a socket (M). The socket (M) is in turn made of a metal capable of being soldered and is arranged in a support (L), for example in a printed circuit board (L) made of insulating material. The contact plug (S with H or with I) has a pin-like core (S) of a metal not capable of being soldered, at least not reliably soldered, secured by means of the insulator (G) in the passage, conductively connected (for example by a bonded wire (D) to the component (E) and surrounded by a sheath (H or I). The sheath (H or I) is in turn electroconductively secured to the core (S), for example by spot welding, and is completely made of a material capable of being soldered or has a material capable of being soldered at least on the point of its surface at which it (H or I) is soldered to the socket (M). Long-time resistant, reliable contact plug soldering, in particular for motor vehicle electronic circuits.
Abstract:
In order to contact power current connecting elements of a component, in particular a relay, with connecting leads of an insulating substrate (1), flat plugs of the component shaped as connecting tongues (10) are welded to bent connecting tabs (12) of a connecting lead (13) embedded in a substrate, for example a printed circuit board. In order to protect plastic materials located next to the weld from damage caused by the welding energy, the end sections of connecting tabs (12) and connecting tongues (10) have a toothed profile, so that individual teeth (16, 17) may be successively welded. The teeth thus quickly reach the melting phase and in the short welding time thermal conductivity does not cause adjacent plastic materials to melt.
Abstract:
The positional tolerances required between contact pins on electrical components and the soldering eyes on flexible circuit boards make assembly work, in particular the production of soldered joints, difficult. The invention calls for a disc (25) to be placed over each contact pin (13) of an electrical component (12). The soldering eye (21) on the circuit board (15), which surrounds the contact pin (13) with a relatively large amount of play, is placed against the disc (25). The contact pin (13), the soldering eye (21) and the area of the disc (25) lying within the soldering eye (21) are then covered with solder (32). In equipment with soldered joints (31) produced in this way, the soldering eyes (21) on the circuit board (15) are contacted with the contact pins (13) of electrical components (12) by a solder bond (32) covering the soldering eye (21), the contact pin (13) and the area of the disc (25) inside the soldering eye.
Abstract:
The present image sensor mounting system is particularly adapted to the mounting of a linear sensor array, of the type having a transparent window on a front surface and a thermal and electrically conductive back surface. The system provides superior electrical and thermal transfer characteristics. A heat sink having at least one flat surface is positioned to make thermal contact with the back surface of the image sensor. A multilayer circuit board having layers of conductive material separated by layers of insulating material and having an opening therethrough sufficient in size to accept the heat sink provides the system support. A metal plating extends from one surface of the board through the opening in the board to the opposite surface of the board with selected ones of the layers of conductive material making electrical contact with the metal plating. The heat sink is mounting in the multilayer circuit board opening in thermal and electrical contact with the metal plating. A layer of thermal and electrically conductive grease is layered between the at least one surface of the heat sink and the conductive back surface of the linear sensor array.
