Abstract:
A submount for arranging electronic components on a substrate is provided. The submount comprises a head member and at least one substrate-engaging member protruding from the head member. The head member comprises at least two, from each other isolated, electrically conductive portions, where each electrically conductive portion comprises a component contact, adapted for connection of electronic components thereto, and a substrate contact on arranged on said substrate side, adapted for bringing said electrically conductive portions in contact with a circuitry comprised in said substrate. The submount of the present invention may be used to attach electronic components, such as light-emitting diodes, to a textile substrate, without the need for soldering the electronic component directly on the substrate.
Abstract:
A chip fuse includes a substrate, a fuse element extending on the substrate, and first and second wire leads coupled to the fuse element. Contact pads may extend over portions of the rase element and establish electrical connection to the first and second leads. A conductive medium such as solder encircles the substrate to securely form a mechanical and electrical connection to the leads.
Abstract:
An electrical assembly including a substantially planar substrate having at least one recess therein and a plurality of electrical components. The electrical components are positioned in the at least one recess and include a first electrical component and a second electrical component. Each of the electrical components has a body and an electrical connection. The electrical connection of the first electrical component and the electrical connection of the second electrical component are aligned with each other when the body of the first electrical component is in a recess and the body of the second electrical component is in a recess.

Abstract:
An LED light module assembly (10) for use with high power, high light output LED's includes a thin flexible circuit board (22) with surface mounted LED's (12) and other electronic components which is attached to a metal heat sink (40) using a layer of a thermally conductive adhesive (46), such as a thermally conductive epoxy adhesive. A conduction path is provided from the LED carrier (16) through the flexible circuit board (22) by the incorporation of one or more thermally conductive vias (32) in the region of the attachment pad (38) used to bond the LED (12) to the flexible circuit board (22). These vias (32) provide a conduction path from the back side of the LED carrier (16) through the circuit board (22) to the thermally conductive adhesive (46) and heat sink (40). The LED light module assembly (10) has the capacity to dissipate between about 10-14 W of power without exceeding a maximum LED junction temperature of about 125°C.
Abstract:
The invention relates to the spatial arrangement of radially and axially cabled components on a circuit card (4). According to the invention, at least one axially cabled component, e.g. a diode (2), and optionally an axial SMD component, are arranged beneath at least one radially cabled component, e.g. an encased capacitor (1) and directly adjacent to the leads thereof (7, 8). In another embodiment, the body of the axially cabled component (2) is partly surrounded by at least one lead (7) of the radially cabled component (1), thus optimally utilizing the space beneath said component (1).
Abstract:
In this application, a description is given of a passive component comprising two electric connections with a plug-in portion for securing and electrically connecting the component to a printed circuit board, for example an electrolytic capacitor. In accordance with the invention, this component is so constructed that both plug-in portions are provided with two pins, with the plug-in portions being so positioned that the four pins do not extend in a flat plane. By virtue of the measure in accordance with the invention, resoldering of such components can be dispensed with. The use of pins whose length and width are different enables the manual installation of the components in accordance with the invention in the correct position to be simplified.
Abstract:
An electrical component provided with connection wires (5, 6) such as for example a gas-filled overvoltage diverter (1) has to be held in a stable horizontal position on a printed circuit board (11) for soldering purposes. The free ends (9, 10) of the connection wires (5, 6) are so bent that they form feet to hold the component (1) in a stable horizontal position. Two forward-facing connection wires (5, 6) are bent twice like a leg where the lower parts of the legs (9, 10) face forward and form flattened feet for the steadiness of the component.
Abstract:
A self centering coil (200) includes a coil section (202) and also having curved end sections (206 and 204) at opposite sides of the coil section (202). The curved end sections are preferably substantially flat and in a plane which is parallel to the center axis (306) of the coiled section (202).
Abstract:
The add-on control device has a housing (16) open on one side which is attached to the housing block (10) of a hydraulic unit. In the housing (16) of the control device there is an electronic circuit, especially a final power stage, on a conductive film (26). The conductive film (26) is designed and constructed in such a way that direct contact with the connecting pins (22) of the magnetic valves (12) (consumers) and, at the same time, direct contact with the plug component (31) is possible. The conductive film (27) thereby acts as both the substrate for the circuit or circuit components (28) and a connection between the consumers (22) and the circuit or between the circuit and the plug component. The direct connection between the consumers (12) and the plug component (31) to the conductive film (26) eliminates the need for costly additional plug connections.
