Zhongke Yichuang (Guangzhou) Technology

Zhongke Yichuang (Guangzhou) Technology Co., Ltd., also known as e-tronic, was established in 2021 by founder Ren Guanghui. The company operates in the new energy vehicle sector, specializing in the development and provision of power semiconductors and comprehensive system solutions. Headquartered in Guangzhou, China, the firm has garnered financial backing through a Series A funding round in October 2022, with investors including Infinity Capital Management, SCVC, and Guangzhou Development Zone Investment Group.

The company's core business revolves around providing power module packaging design, trial production, drive system development, and manufacturing services. E-tronic has established an automotive-grade power module packaging production line featuring advanced process technologies like chip placement, silver sintering, and vacuum welding. A notable achievement is the setup of China's first large-area silver sintering production line for SiC TPAK power modules, which has been successfully industrialized. This allows the company to offer full-process packaging manufacturing and testing for both housing and transfer molding structures.

E-tronic's product portfolio includes a series of automotive-grade power modules and is deeply involved in the research and development of motor control systems based on SiC power semiconductors. Their offerings include SiC motor controllers and SiC multi-domain controllers that integrate functions such as MCU, BMS, and VCU. The company has a focus on functional safety and information security in line with new energy vehicle standards, obtaining the first domestic product certification for a SiC motor controller that meets the ASIL-D safety level. Its client base consists of players within the new energy vehicle industry seeking to enhance their systems and build a domestic automotive semiconductor ecosystem.
