Description

Electrode bending device of SiC power device

Technical Field

The utility model belongs to the technical field of the frock design, more specifically, the utility model relates to a SiC power device's electrode bending device.

Background

In the development of the power electronics industry, semiconductor technology plays a decisive role. Among them, power semiconductor devices have been considered as a key component of power electronic equipment. SiC materials have begun to be attracted attention and studied because of their superior physical properties. Compared with Si materials, the high thermal conductivity of SiC materials determines the high current density characteristics of the SiC materials, and the high breakdown field strength and the high working temperature of SiC devices are determined by the high forbidden band width of the SiC materials. Compared with the traditional Si device, the breakdown field strength of the SiC device is 10 times that of the traditional Si device, the heat conductivity coefficient of the SiC device is 3 times that of the traditional Si device, and the SiC device is suitable for high-frequency and high-voltage applications such as a power supply, a solar inverter, an LED and the like. Because the SiC power device electrodes are different in bending direction, the existing bending technology only aims at the power devices with the same electrode bending direction, and the flatness of the manually bent electrodes is poor and the electrode heights are different. The bending directions of main electrodes of the full SiC power device are different, so that the conventional bending equipment cannot meet the electrode bending requirement, and manually bent electrodes are not flat and are different in height, so that the electrode bending requirement cannot be met.
