Abstract:
A thermal interface material (TIM) delivery system includes a removable layer having first and second end portions and first and second surfaces, a TIM having first and second surfaces, a spacing member adjacent the TIM and having first and second surfaces, the spacing member being dimensioned to prevent or reduce pump out of the TIM, and a substrate having a surface. The first surface of the TIM is removably attached to the second surface of the first end portion of the removable layer, and the second surface of the TIM is removably attached to the surface of the substrate. The first surface of the spacing member is in contact with the second surface of the second end portion of the removable layer, and the second surface of the spacing member is in contact with the surface of the substrate.

A lead insertion machine includes a substrate supply, a conductive lead supply, and a lead insertion mechanism. The conductive leads are inserted into lead passages formed in side walls of the substrate. Also disclosed is a method of manufacturing a semiconductor die carrier including the steps of forming a plurality of conductive leads, forming a substrate for holding a semiconductor die, the substrate having a plurality of insulative side walls defining an exterior surface of said substrate, each of the side walls having a plurality of lead passages formed therethrough, and simultaneously inserting at least one of the conductive leads into the lead passage of one of the side walls for retention therein and at least one other of the conductive leads into the lead passage of another of the side walls for retention therein.
Abstract:
A method and related fixtures which permit formation of stacks of thin circuitry-carrying layers. The layers terminate in an access plane having a two-dimensional array of closely-spaced electrical leads. The method includes the steps of measuring the thickness of separate chips, selecting groups of chips having appropriate thicknesses, applying appropriate amounts of epoxy between adjacent chips, aligning the chips (and their electrical leads) in the direction parallel to their planes (i.e., the X-axis), and closing the cavity with an end wall which (a) exerts pressure on the stacked chips and epoxy in a direction perpendicular to the chip planes, and (b) establishes a fixed height of the stack in order to align the leads in the Y-axis. The final fixture provides a fixed-size cavity for confining the layers during curing of thermo-setting adhesive which has been applied between each adjacent pair of layers. An initial fixture is provided for accurately measuring the thickness of each layer under substantial layer-flattening pressure. An intermediate fixture is provided for wet stacking the layers prior to their insertion into the final fixture.

Abstract:
An adapter to connect device leads (12) to contacts arranged in a rectangle on a circuit surface (30). The adapter has a body and leads (26) that extend outwardly, downwardly and then outwardly again in a pair of opposing curves to form feet which match the pattern on the circuit surface (30). The body has sites (16) for connecting with the device (10) and supports conductive elements connecting the leads to the sites. The adapter may connect gullwing-shaped device leads disposed in a rectangle (e.g., QFP) to contacts in a similar pattern. Strain relief elements (32) are shown. The body may include a stack of connected body portions. The device leads may be anchored in holes in the substrate, and may be bent portions of a lead frame sealed in a molded insulating body. Vertically extending resilient single-reed-shaped contacts (224) may connect to a surface of a downwardly extending section on a device package lead (214).
Abstract:
A space-grade solar array includes relatively small cells with integrated wiring embedded into or incorporated directly onto a printed circuit board. The integrated wiring provides an interface for solar cells having back side electrical contacts. The single side contacts enable the use of pick and place (PnP) technology in manufacturing the space-grade solar array. The solar cell is easily and efficiently packaged and electrically interconnected with other solar cells on a solar panel such as by using PnP process. The back side contacts are matched from a size and positioning standpoint to corresponding contacts on the printed circuit board.
