  • Publication number: 20230121505
    Abstract: An electronic element soldering method includes providing a substrate, wherein the substrate has a to-be-soldered position, placing an electronic device including an electronic element, a heating element, and a parallel-connected circuit on the to-be-soldered position of the substrate, adding a solder between the electronic element of the electronic device and the to-be-soldered position of the substrate, applying a heating current into the parallel-connected circuit of the electronic device to allow the heating element of the parallel-connected circuit to generate a thermal energy for melting the solder, thereby securing the electronic element on the to-be-soldered position of the substrate via the solder that is melted, applying a breaking current that is larger than the heating current into the parallel-connected circuit to allow an open to occur in a parallel branch corresponding to the heating element of the parallel-connected circuit, and stopping the breaking current.

  • Patent number: 11225433
    Abstract: A sintered machinable glass-ceramic is provided. The machinable glass-ceramic is formed by mixing phyllosilicate material having a sheet structure, with a glass fit and firing the mixture at relatively low temperatures to sinter the phyllosilicate, while maintaining the sheet-like morphology of the phyllosilicate and its associated cleaving properties. The sintered machinable glass-ceramic can be machined with conventional metal working tools and includes the electrical properties of the phyllosilicate. Producing the sintered machinable glass-ceramic does not require the relatively high-temperature bulk nucleation and crystallization needed to form sheet phyllosilicate phases in situ.

    Abstract: A light-emitting chip carrying structure and a method of manufacturing the same are provided. The method includes transferring a plurality of light-emitting chips to a circuit substrate; driving a leveling substrate to concurrently press the light-emitting chip by a carrier device such that a plurality of distances each defined between a light-emitting surface of each of the light-emitting chips and a top surface of the circuit substrate are the same; fixing the light-emitting chips on the circuit substrate by a heating device while the light-emitting chips are pressed by the leveling substrate; and then removing the leveling substrate by the carrier device. Therefore, the light-emitting surfaces of the light-emitting chips relative to the top surface of the circuit substrate have the same flatness, and the light-emitting surfaces of the light-emitting chips are disposed on the same plane.
