  • Patent number: 10772214
    Abstract: A manufacturing method for a circuit board in which a pin inserted in a through-hole of a land is welded to the land is disclosed. The land is covered with a white layer, and an irradiation angle of a laser beam with respect to the circuit board is adjusted so that reflected light of the laser beam emitted to the pin reaches the white layer on the land. As the reflected light of the laser beam is allowed to reach a white region provided on the land, the reflected light is scattered on the white region. A rate of absorption of the laser beam by the land is decreased, and a temperature increase of the land is restrained. As a result, a damage of an insulating part around the land is restrained.

  • Patent number: 10759000
    Abstract: The present invention provides a fiber laser system that delivers from a single processing cable a multibeam output. The present invention allows for controlling multiple fiber laser modules and delivering their respective outputs in a pre-determined sequence but in a single processing cable, thereby providing multiple processing steps on a work piece that heretofore required separate optics for each beam. Custom fiber laser systems that combine processing steps tailored for a specific industrial application such as pre-heating, cutting, cleaning, welding, brazing, ablating, annealing, cooling, polishing and the like can be readily provided because of the present invention.

  • Patent number: 10668578
    Abstract: Methods and systems for welding a terminal of a battery cell to corresponding terminal tab or busbar are described using a magnet that causes the terminal and tab/busbar to be placed in physical contact. The terminal of a battery cell is aligned in contact with the tab/busbar by the force of a magnetic field. A welder, e.g., a laser welder, can then generate a laser weld beam to weld the terminal of the battery cell to the tab/busbar. Next, the laser weld beam is narrowed, reducing the first diameter to a smaller second diameter. Without touching the tab/busbar or terminal of the battery (which could affect the welding operation), the magnetic field can cause a force that brings the tab and terminal in contact during welding.
