Abstract:
A lightweight radio/CD player for vehicular application is virtually "fastenerless" and includes a case (68) and frontal interface (70) formed of polymer based material that is molded to provide details to accept audio devices such as playback mechanisms (if desired) and radio receivers, as well as the circuit boards required for electrical control and display. The case and frontal interface are of composite structure, including an insert molded electrically conductive wire mesh screen (212) that has been pre-formed to contour with the molding operation. The wire mesh provides EMC, RPI, BCI and ESD shielding and grounding of the circuit boards via exposed wire mesh pads and adjacent ground clips (218)

The PCB architecture is bifurcated into a first board carrying common circuit components in a surface mount configuration suitable for high volume production, and a second board carrying application specific circuit components in a wave soldered stick mount configuration. The major components and subassemblies are self-fixturing during the final assembly process, eliminating the need for dedicated tools, fixtures and assembly equipment. The major components and subassemblies self-interconnect by integral guide and connection features effecting "slide lock" and "snap lock" self-interconnection. The radio architecture includes improved push buttons employing 4-bar living hinge linkage and front loaded decorative trim buttons.

Um den Einbau eines Drehratensensors auf eine Platte, insbesondere eine Leiterplatte, in einer Navigationseinheit zu unterstützen, bei dem der Drehratensensor den passenden Vorhaltswinkel zum Gehäuse der Navigationseinheit vorweist, sind folgende Schritte vorgesehen: a) Durchtrennen der Platte entlang einer sich nicht schließenden Trennlinie, welche so geformt ist, dass eine Lasche (18) entsteht, die mit dem Rest der Platte eine Verbindung aufweist. b) Abwinkeln der Lasche (18) entlang einer Biegekante derart, (22) dass sich ein bestimmter Winkel zwischen Lasche (18) und Rest der Platte einstellt. c) Befestigung des Drehratensensors (14) auf der Lasche (18) oder auf der Platte im Bereich der herzustellenden Lasche (18).
Abstract:
A resonance security tag (1) comprises a dielectric foil material (2) provided with conductive material layer patterns (3-7) on both sides. The conductive material layer patterns are formed to provide an inductor (3) and a capacitor (4, 6) positioned inside the inductor (3), and mutually connected to form a resonance circuit. By cutting (9) the capacitor (4, 6) free of the dielectric foil material (2) and folding the capacitor (4, 6) away from the position inside the inductor (3), this part is left free for the penetration of magnetic flux through the inductor (3), whereby the detection level is improved and a possibility of reducing the size of the resonance security tag is provided.
Abstract:
The aim of the invention is to join in a simple and inexpensive manner at least two parts. Said aim is achieved by a method for joining at least two parts (1, 2) which are brought into contact with each other at least in one joining area. According to the inventive method, a support element (5) is in contact with a first (1) of the two parts (1,2) at least in the joining area, at least one protrusion (3a-c) penetrates the parts (1, 2) in the joining area in the direction of the support element (5), the support element (5) is two-dimensionally supported at least in the joining area counter to the penetrating movement of the protrusion (3a-c), and the penetration of the parts (1, 2) by the protrusion (3a-c) and the counteracting two-dimensional support of the support element (5) cause the penetrated material of the parts (1, 2) to be deformed in a plastic manner in a direction that is perpendicular to the penetrating movement of the projection (3a-c), the support element (5) also being deformed.
Abstract:
An electrical device (10) includes a flat flexible insulating substrate (12) having an opening (14) therethrough. A flat conductive terminal (16) is deposited on one side (12a) of the substrate at the opening. A portion (20) of the terminal is formed through the opening (14) so that the terminal has opposite ends at opposite sides of the substrate. One end (20) of the terminal forms a contact portion thereof, and an opposite end (18) of the terminal forms a land portion for receiving a solder ball (22).
Abstract:
Le but de la présente invention est d'obtenir un circuit électronique utilisé par exemple dans une carte ou une étiquette très bon marché tout en conservant une fiabilité élevée. Ceci concerne en particulier la connexion d'un ou des composants électroniques sur les pistes conductrices au moyen de ponts conducteurs qui traversent le substrat.Le circuit électronique selon l'invention comprend au moins un composant électronique (6), un substrat (5), sur une première face de ce substrat est appliqué une couche adhésive et une couche conductrice constituée par une pluralité de pistes (4). Le composant électronique (6) comporte au moins deux plages de connexion (7). Une de ces plages (7) est reliée électriquement ô la couche conductrice par un pont conducteur formé par un segment conducteur (1) délimité dans la couche conductrice seule. Ce segment (1), dépourvu de substance adhésive, traverse le substrat (5) au moyen d'un passage (2, 3) et relie la plage de connexion (7).
Abstract:
Singulation method according to the present invention is based on the mechanical resistance difference between conductor layer (1), insulating material (2) and the base material (3) patterns. The conductor peel band (5) is created along the edges of the flexible circuit (4) on both side of base material. Flexible circuit (4) is separated from the panel by lifting the start point (6) and pulling the conductor peel band (5) till the end along the edges of the circuit (4).
