Abstract:
A novel technique utilizing the precision of printed circuit board design and the physical versatility of thin, fexible substrates is disclosed to produce a new type of ion reflector. A precisely defined series of thin conductive strips (traces) are etched onto a flat, flexible circuit board substrate. Preferably, the thin conductive strips are further apart at one end of the substrate and get increasingly closer towards the other end of the substrate. The flexible substrate is then rolled into a tube to form the reflector body, with the conductive strips forming the rings of the ion reflector. The spacing between the traces, and hence the ring spacing, can be readily varied by adjusting the conductor pattern on the substrate sheet during the etching process. By adjusting the spacing between the rings, the characteristics of the field created by the reflectron can be easily customized to the needs of the user.
Abstract:
A circuit on a curved surface is provided where the circuit includes at least one circuit element on the curved surface, at least one conductive path on, and integral with, the curved surface, where the conductive path is connected to the circuit element, and means for supplying power along the conductive path to the circuit element. The curved surface may be a helmet, in which case a plurality of pairs of light emitting elements may be provided thereon where the pairs emit light sequentially one pair at a time in order to maximize the brightness of the light emitted and maximize battery life. Also, means for receiving an infrared or ultrasonic signal may be provided such that the light emitting elements emit light in a certain manner as a result of the signal being received. Also provided is a method of forming at least one conductive path on a curved surface, such as on a helmet, where the method comprises aiming a beam of light to the curved surface, providing relative movement between the beam of light and the curved surface causing the beam of light to form a path on the curved surface, and laying conductive material on the path. The beam of light may be aimed at a mirror which bends the beam of the light to the curved surface, and the mirror may be moved by a stepper motor controlled by a computer. In addition, the curved surface may be moved by a stepper motor controlled by the computer.
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:
Enhanced short circuit damage protection by using circuit card and electronic assembly features to steer liquids, including water, onto detector arrays. In a typical implementation, a circuit card has detection elements in one or more places implemented as artwork on an outer circuit layer. The finished circuit card assembly is conformal coated with masked areas over detection artwork. When the masking is removed, channels are left behind for liquids to flow toward and pool over detection artwork. In other implementations through shaping, additive or subtractive manufacturing processes, cavities are left behind for liquids to collect over detection artwork.

Abstract:
Die Erfindung betrifft ein Verfahren zur Herstellung eines umgeformten Schaltungsträgers in Form eines Laminats aus Haftvermittlerfolie (1), ggf. Kleberschicht (2), Schaltungsträgerfolie (3) und rein metallischer Leiterbahn (4), letztere mit einer bevorzugten Dickenabmessung in der Größenordnung von 1000 Atomlagen. Ferner betrifft die Erfindung einen umgeformten Schaltung sträger (1-4). Bei dem erfindungsgemäßen Verfahren wird der Schaltungsträger (1-4) umgeformt mittels eines gasförmigen Druckmittels, wobei das Umformen oberhalb der Glastemperatur und unterhalb der Schmelztemperatur der umzuformenden Schaltungsträgerfolie (3) unter hohem Gasdruck schlagartig erfolgt. Dank der Erfindung lassen sich erstmals stark umgeformte, insbesondere frei oder sphärisch geformte Schaltungsträger auch mit rein metallischen Leiterbahnen erzeugen. Durch optionale Hinter spritz ung (9), Aufbringung von Dekorlagen (1 1) und/oder Überzugsschichten (10) lassen sich multifunktionale, nahtlos freigeformte Kunststoffbauteile mit Elektronikintegration erhalten.
