Abstract:
Electrical components in an electronic device are mounted on substrates such as printed circuits. Printed circuits contain signal paths formed from metal traces. The signal lines in the signal paths of the printed circuits are coupled together using electrical connection structures such as printed circuit board-to-board connectors, contacts joined by anisotropic conductive film, or contacts joined using solder. Electrical connection structures may be surrounded by conductive resilient ring-shaped structures such as conductive foam structures or spring structures. The conductive foam structures may be provided with a metal layer with which the conductive foam structures are soldered to a ring of metal on a printed circuit. Strain relief structures may be formed from an elastomeric ring that surrounds the electrical connection structures or an overmolded plastic structure. Coating layers and conductive plastic may be used in providing strain relief structures with electromagnetic interference shielding capabilities.

The first and second longitudinal axes are installed substantially parallel to the first plane.
Abstract:
An electrical interconnection system comprises a bifurcated, multilayer flex circuit having electrode pads on the inner surfaces of the bifurcation. Electronic components are mounted on one or both sides of the flex circuit by conventional means. When the bifurcation is spread apart, the electrode pads are alignable with respective contacts on a printed circuit board. After bonding the pads to the contacts by soldering, conductive adhesive, or other means, a secure electrical connection is maintained while still allowing the flex circuit to bend somewhat from side to side, creating additional design options not available with rigidly mounted components and modules.

A substrate having a plurality of light-emitting elements mounted thereon is described. The substrate may be mounted in a lighting apparatus and may include a surface on which the plurality of light-emitting elements are mounted and one or more holes through which heat may be conducted from the first surface to another surface of the substrate. For example, a heat conductive and electrically non-conductive material may cover a surface of the one or more holes. According to some arrangements, the surface of the substrate may include an electrically non-conductive layer and an electrically conductive layer such that the electrically non-conductive layer is electrically isolated or separated from the electrically conductive layer.

Abstract:
The present invention provides an innovative means for efficient and secure component assembly and for ensuring secure electrical connections in a small diagnostics device where available space for fasteners is limited. In one embodiment, principles of leverage are employed to produce a force at a location where space is available. The force is transferred to a different location of the assembly where it is used to maintain secure connections between components.
