Notched lead wire for a solid electrolytic capacitor
A capacitor containing a solid electrolytic capacitor element including a sintered porous anode body and a relatively large diameter anode lead wire is provided. The lead wire is electrically connected to the anode body for connection to an anode termination. Further, the lead wire has a diameter that is at least about 10% of the height of the porous anode body to improve the points of contact between the anode body and wire to reduce ESR. A portion of the lead wire extends from a surface of the anode body in a longitudinal direction. At least one notch can be formed in the portion of the lead wire that extends from the anode body. The notch can be formed via a laser or by cutting, punching, or sawing and can serve as the point of electrical connection between the anode termination and the lead wire.
LASER WELDING OF METAL PIN PAIRS WITH TIME-DEPENDENT SCAN PATTERN AND ENERGY INPUT
A method for laser welding a pair of metal pins delivers a laser beam to a work-side of the pair of metal pins where a respective pair of surfaces of the metal pins are adjacent to each other and face in the same direction. The laser beam first traces a first path on the work-side to form a melt pool by keyhole welding. The first path crosses an interface between the metal pins. After tracing the first path, the laser beam is switched to trace a second path on the work-side with the laser beam at a delivered rate of energy per unit path length that is less than the one used for the first path. The second path crosses the interface and is within the first path. The method is well-suited for welding of hairpin and I-pin stators.
