  • Publication number: 20240068135
    Abstract: Interlacing equipment may be used to form fabric and to create a gap in the fabric. The fabric may include one or more conductive strands. An insertion tool may be used to align an electrical component with the conductive strands during interlacing operations. A soldering tool may be used to remove insulation from the conductive strands to expose conductive segments on the conductive strands. The soldering tool may be used to solder the conductive segments to the electrical component. The solder connections may be located in grooves in the electrical component. An encapsulation tool may dispense encapsulation material in the grooves to encapsulate the solder connections. After the electrical component is electrically connected to the conductive strands, the insertion tool may position and release the electrical component in the gap. A component retention tool may temporarily be used to retain the electrical component in the gap as interlacing operations continue.

  • Patent number: 9955756
    Abstract: A shell element for the buckle cover of a seat belt buckle is disclosed. The shell element comprises a base body made of a hard elastomer and an outer and an inner surface. So that when the buckle cover bears against a further vehicle element with a hard surface, no wear and no undesirable noise is generated and so that the seat belt buckle permanently has attractive visual and haptic properties, a further element made of a soft elastomer is directly connected to the base body and is connected thereto by a material and/or positive connection, said further element forming at least one part of the outer surface of the shell element.

  • Patent number: 9806056
    Abstract: Integrated circuits are packaged by placing a plurality of semiconductor dies on a support substrate, each one of the semiconductor dies having a plurality of terminals at a side facing the support substrate and covering the semiconductor dies with a molding compound to form a molded structure. The support substrate is then removed from the molded structure to expose the side of the semiconductor dies with the terminals, and a metal redistribution layer is formed on the molded structure and in direct contact with the terminals of the semiconductor dies and the molding compound. The redistribution layer is formed without first forming a dielectric layer on a side of the molded structure with the terminals of the semiconductor dies. A corresponding molded substrate and individual molded semiconductor packages are also disclosed.

  • Patent number: 9099454
    Abstract: A semiconductor package is manufactured by providing a semiconductor die with a terminal at a first side of the die, providing a material coupled to the die at an opposing second side of the die and embedding the die in a molding compound so that the die is covered by the molding compound on all sides except the first side. The molding compound is thinned at a side of the molding compound adjacent the second side of the die, to expose the material at the second side of the die without exposing the second side of the die. An electrical connection is formed to the terminal at the first side of the die. In the case of a transistor die, the terminal can be a source terminal and the transistor die can be attached source-down to a metal block such as a die paddle of a lead frame.
