  • Patent number: 6505665
    Abstract: A first fixture holds a plurality of circuit components backside up in a substantially coplanar relationship. An adhesive applying device, such as screen printer, applies adhesive to the backside of each circuit component. A second fixture is aligned with and placed on the first fixture. The fixtures are then flipped so that the circuit components are supported in a right side up position by the second fixture. A device such as a pick and place machine, may then be used to transfer the circuit components from the second fixture to a substrate.

  • Patent number: 6290804
    Abstract: A technique for forming a film of material (12) from a donor substrate (10). The technique has a step of introducing energetic particles (22) in a selected manner through a surface of a donor substrate (10) to form a pattern at a selected depth (20) underneath the surface. The particles have a concentration sufficiently high to define a donor substrate material (12) above the selected depth. An energy source is directed to a selected region of the donor substrate to initiate a controlled cleaving action of the substrate (10) at the selected depth (20), whereupon the cleaving action provides an expanding cleave front to free the donor material from a remaining portion of the donor substrate.

  • Patent number: 6274240
    Abstract: A method of forming electrically insulated magnet wire and a coil formed therefrom. The method involves feeding a flexible electrical insulation tape along a path which converges with a path along which the wire to be wrapped is conveyed. Along the tape travel path at a location upstream of the point where the tape and wire converge, a quantity of heat activated adhesive that has been heated to a sticky state is applied to the passing tape. Then, before the adhesive coating sets, the adhesive coated tape reaches the point of convergence with the wire and is adhered to the wire to provide an electrical insulating wire wrap. The method of the invention provides for a longitudinal, partial wrapping of a conductor wire that furnishes suitable turn-to-turn insulation in coils formed with the wrapped wire.
