Abstract:
A multi-layer circuit board comprised of two or more circuit board substrates (10, 12) shaped by injection molding with mating interconnecting pins (22) and holes (24) and banded together with an electrically insulated adhesive material (28). Circuit leads (14, 16, 18, 20) are provided on both sides of each substrate recessed into channels (85) formed in the surface of the substrate during the molding process. Electrical interconnection of the layers of circuitry occurs where the conductive materials of the circuit leads (14, 16) passes down through component lead holes (26) axially located in the interconnecting pins (22) and around the exterior of the interconnecting pins where contact is made with the conductive material coating on the interior of the interconnecting holes (24). A method of making the multi-layer board includes injection molding the substrates (10, 12) in a suitable shaped mold (74, 76) plating substantially all of the surface of the substrates with the conductive material (82) masking with a plating resist (84), plating again with conductive material (88), removing the plating resist and flash-etching to remove the conductive material (82) initially plated and masked by the plating resist (84) so as to define the circuit leads (14, 16, 18, 20). The preferred method uses a roller to apply the plating resist to some surfaces of the substrates.
Abstract:
Assemblage comprenant une bobine pourvue d'une bobine de fil (50) et une plaque de circuit imprimé (34) pourvue de conducteurs (44). La bobine (50) possède une première et une deuxième bornes (68, 70) s'étendant au travers d'ouvertures correspondantes (40, 42) dans la plaque de circuit imprimé (34). Chaque borne (68, 70) présente une première et une deuxième rainures (72, 74) s'étendant le long de la borne et chaque extrémité (82) du fil de bobine (80) s'étend le long et à l'intérieur de la première rainure (72), au travers de la pointe (84), et le long et à l'intérieur de la deuxième rainure (74) de la borne respective (68, 70) et est soudée sur le côté opposé de la plaque de circuit imprimé. L'assemblage est exécuté en une seule opération dans laquelle une ouverture simple dans la plaque de circuit imprimé sert aussi bien d'ouverture pour la borne que d'ouverture pour l'extrémité du fil.

An electronic assembly which comprises a plastics substrate in turn comprising a protected surface laterally delimited a first wall extending longitudinally along a first edge and a second wall extending longitudinally along a second edge, in such a way that the protected surface is between the first and second walls, the electronic assembly further comprising a conductive track directly deposited between the first and second walls.
Abstract:
A wiring board 1 includes a base 10 having extensibility and a wiring 40 formed on the base. The wiring includes a wiring portion 20 and a conductor portion 30. The wiring portion is formed on the base and extends in a first direction P crossing (for example, perpendicular to) a longitudinal direction X of the base. The conductor portion is formed on the wiring portion and extends in the first direction. Even when the wiring board is extended along a main extension axis S in parallel with the longitudinal direction of the base, change of the resistance of the wiring is prevented. Thus, the wiring board represents stable characteristics.

Abstract:
A substrate (101) includes a storage portion (101C) which is defined by a base for mounting a light emitting element (102) and a wall portion standing up on and from the base. A package (100) is structured such that the upper end of the wall portion so formed as to surround the periphery of the storage portion (101C) is connected to a cover (103) to thereby seal a light emitting element. A seal structure (130; 330; 430) is composed of an uneven portion (140; 340) formed on the lower surface side surface of the base (101A), a close contact layer (150) formed on the surface of the uneven portion (140; 340), a power supply layer (160) formed on the close contact layer (150), and an electrode layer (170) formed on the surface of the power supply layer (160). The uneven portion(140; 340) includes a first recessed portion (180) formed at a position spaced in the radial direction from the outer periphery of a through electrode (107) or from the inner wall of a through hole (120), and a second recessed portion (190) formed at a position spaced further outwardly from the first recessed portion (180).
