  • Publication number: 20210202439
    Abstract: A high power module is provided, which includes a substrate, plural first power chips, plural second power chips, a positive electrode plate and a negative electrode plat. The substrate includes a first metal area, a second metal area, a third metal area disposed between the first metal area and the second metal area. The first power chips are disposed on the third metal area and connected to the first metal area via plural first connection elements. The second power chips are disposed on the second metal area and connected to the third metal area via plural second connection elements. The positive electrode plate is C-shaped and connected to the first metal area. The negative electrode plate is C-shaped and connected to the second metal area; the direction of the opening of the negative electrode plate is contrary to that of the opening of the positive electrode plate.

  • Publication number: 20210202344
    Abstract: A semiconductor device includes an insulating thermal substrate, a metal wiring layer and a heat-dissipation component. The metal wiring layer includes a plurality of engaging structures. The plurality of engaging structures is disposed between the insulating thermal substrate and the heat-dissipation component, and the heat-dissipation component applies solder structures to connect the metal wiring layer by having the solder structures to wrap partly the plurality of engaging structures. In addition, a method for fabricating the same semiconductor device is also provided.

  • Publication number: 20210155290
    Abstract: A steering device includes a steering power unit, a transmission unit, an upper control arm, a steering element, an eccentric bolt and a steering knuckle. The steering power unit has at least one torque-output end. The transmission unit is connected with the torque-output end. The steering element is connected with the transmission unit. The eccentric bolt, installed at the upper control arm, is connected with the steering power unit. The steering knuckle, mounted to a wheel disc, is connected with the steering element and the upper control arm, and used for controlling the wheel disc. The steering power unit drives the steering element to push or pull the steering knuckle for controlling a turning angle, and simultaneously drives the eccentric bolt to have the upper control arm to push or pull the steering knuckle for varying a camber angle of the wheel disc. In addition, a steering method is provided.
