According to Chen Zhaoyin, Chairman of J-Link Electronics, J-Link Electronics has received mass production orders and projects for electric drive and electronic control from multiple OEMs in the field of new energy vehicles, and has also established deep cooperation with eVTOL aircraft head OEMs. Its 800V high-voltage silicon carbide process module has been validated and supplied in bulk at multiple OEMs.

Looking ahead to the future, Chen Zhaoyin said, "The achievement of these achievements cannot be separated from the close cooperation of our partners. We will continue to uphold the concept of openness and win-win, work hand in hand with all partners, jointly promote industry technological progress, and promote industrial ecological prosperity

It is reported that the construction of J-Link Electronics' SiC module production line can be described as "progressing rapidly":

In July 2024, J-Link Electronics officially launched the construction of Anhui's first SiC power module project, with a total investment of over 100 million yuan;

In January 2025, the 001 product "HPD Full Bridge SiC Power Module" A sample of the J-Link Electronics SiC module project was announced to have been successfully launched. The new production line took only six months from the beginning of construction to the production and manufacturing capability;

It is reported that after the comprehensive construction and delivery of the production line, the annual production capacity can reach one million units, which will become an important support for J-Link Electronics' vertical integration layout of the supply chain.

In his speech, Chen Zhaoyin stated that the smooth construction and production of the new SiC automotive power module production line cannot be achieved without the strong support of leaders and partners from various levels of government in Anhui Province and friends from all walks of life. J-Link Electronics has closely collaborated with upstream and downstream partners, greatly promoting the production process. Firstly, it has established deep cooperation with top equipment suppliers, material suppliers, and research institutions both domestically and internationally, successfully overcoming multiple challenges in the research and mass production of silicon carbide power modules; Secondly, the new production line adopts internationally leading packaging equipment and process technology, which not only significantly improves product yield and quality stability, but also reaches the leading level in the industry.

Chen Zhaoyin stated that as the first advanced process silicon carbide vehicle specification module production line in Anhui Province, J-Link Electronics' new production line embodies the company's latest achievements in technological innovation and process breakthroughs.

Specifically, the SiC module production line launched by J-Link Electronics has four core competitive advantages, which can meet the high reliability requirements of power system core power components in fields such as 800V high-voltage platform vehicles and eVTOL aircraft

One is the original equipment ecosystem: key process equipment adopts internationally leading packaging equipment manufacturers. At the same time, based on the pain points in the SiC power module packaging industry, we jointly develop with industry equipment giants to improve and enhance the equipment in a targeted manner, making it more stable and achieving higher product yield and quality.

Secondly, it has advanced packaging technology: using pressure sintered silver technology combined with DTS copper wire bonding, it has high reliability and low stray inductance. NTC and heat dissipation bottom plate adopt soldering technology, which simplifies the process flow, does not require cleaning, and is more environmentally friendly.

The third is the intelligent quality control system: comprehensive performance testing and reliability evaluation of packaged modules can effectively ensure that product quality and performance meet design requirements. ‌

The fourth is the flexible intelligent manufacturing mode: adopting the "intelligent island+human-machine collaboration" architecture, each process equipment adopts modular design in the form of islands, combining automation and semi automation. While achieving automation, digitization, and intelligence, it can meet the ever-changing product design and growing market demand, and the equipment is more flexible and the utilization rate is higher.

At the event, J-Link Electronics highlighted the launch of two SiC power modules and multiple SiC electronic control and electric drive assembly products:

HPD full bridge SiC power module: Currently, J-Link Electronics' HPD full bridge SiC power module has successfully passed the AQG-324 vehicle grade reliability certification. It adopts a double-sided silver sintering process, effectively reducing on resistance and parasitic inductance, greatly improving power cycle life. The entire product chain adopts a no cleaning process, making the process simpler and more environmentally friendly.

DCM half bridge SiC power module: This product also has unique technical features, using the double-sided silver sintering process of the chip. Compared with similar products, its stray inductance can be within 5nH, significantly reducing the system inductance of the module in the electronic control.

SiC motor controller/800V SiC electric drive assembly: Both types of products use self-developed and self-made SiC power modules. The former has a maximum efficiency of 99.8%, while the latter uses oil cooled flat wire motors, leading the industry in lightweight level at the same power level.

J-Link Electronics has achieved a leading advantage in the industry with its technology and production capacity layout in the fields of silicon carbide power modules and 800V high-voltage electric drive assemblies. Chen Zhaoyin said that in the future, they will take this opportunity to continue to increase research and development investment, deepen technological accumulation, and aspire to become a global leading supplier of silicon carbide process modules and high-voltage electric drive assemblies, providing more efficient and reliable solutions for industries such as new energy vehicles, eVTOL aircraft, and renewable energy.
