Abstract:
The present disclosure is generally directed to illumination devices, and methods for making the same. The device, in particular, includes a first conductor layer, a first insulator layer disposed on the first conductor layer and having at least one first aperture defined therein through the first insulator layer, a second conductor layer disposed on the first insulator layer and having at least one second aperture defined therein through the second conductor layer and positioned to align with the at least one first aperture, and a light manipulation layer disposed on the second conductor layer and having at least one pair of apertures defined therein through the light manipulation layer including a third aperture and a fourth aperture, where the third aperture is positioned to align with the at least one second and first apertures.
Abstract:
A method of making a multi-layer electronic circuit and the circuit made thereby, wherein the method comprises making each of at least two interconnected circuit layers by applying a layer of conductive material (34, 36) on a layer (38) of insulative material using a stamping die which defines a selected pattern in the conductive layer (34, 36), aligning and laminating the circuit layers to a substrate (32), and interconnecting the layers of the conductive material (34, 36) at selected locations. Apertures (40, 42, 44) are defined at selected locations in the insulative material for a subsequent electrical interconnection. These apertures (40, 42, 44) may be defined by stamping them into the insulative material simultaneously with the application of the patterned conductive material on the insulative material.
Abstract:
Passive conductor component for surface mounting on a printed circuit board. The invention relates to a conductor component comprising a body with two substantially parallel conducting faces, the first face (24, 26) to be welded to a printed circuit board surface and the second face (22) designed to form an apparent conducting surface, a cavity being formed between the two faces. Application to surface-mounted printed circuit boards.
Abstract:
Conductive wiring members, such as copper foil wiring (2a), (2b) printed on both sides of an insulating substrate (1), or the like, are connected by passing a conducting wire (7), (9) provided with a solder ball (8), (10) through a through-hole (3) in the vicinity of the conductive wiring members (2a), (2b), and then soldering the conductive wiring member (2a) or (2b) to the part of the conducting wire (7) or (9) on one surface by dip soldering or flow soldering, thereby melting the solder ball (8) to connect the part of the conducting wire (7) or (9) to the conductive wiring member (2a) or (2b) on the other surface.
