Beijing 8-inch BAW filter joint production line to achieve line

On December 30, 2022, in the clean workshop of the 8-inch BAW filter production line located in Yizhuang, Beijing, with the start-up of various process equipment, the professional review of the expert group and the joint witness of all parties in the industry, Beijing Sai Microelectronics Co., Ltd. ("Sai Microelectronics") and Wuhan Minsheng New Technology Co., Ltd. ("Wuhan Minsheng") announced the realization of the Beijing 8-inch BAW filter joint production line.

Since the strategic cooperation was reached in August 2021, the two teams have worked together to overcome many difficulties such as the adverse effects of the epidemic and the extension of the equipment delivery cycle, and finally established a domestic leading dedicated 8-inch RF filter within the originally planned time. Production line, and has relatively complete industrial supporting facilities and a certain industrial scale.

In order to evaluate and verify the production line status, Wuhan Minsheng and Saiwei Electronics jointly convened a number of well-known experts from the same industry in China to conduct a line-through review of the "Beijing 8-inch BAW Filter Joint Production Line. Through listening to the project report, reviewing the project materials, visiting and evaluating the operation status of production line equipment, conducting on-site testing and other professional review processes, the review expert group unanimously believes that the equipment configuration of the project matches the production capacity, the production line has reached the requirements and standards of the project line, and has the ability to carry out the next step of capacity climbing, yield improvement and large-scale product mass production. It is recommended that the project unit further speed up the introduction of mass production, reach full production and yield status as soon as possible.

Beijing 8-inch BAW filter joint production line, which means that Wuhan Minsheng and Saiwei Electronics have achieved phased results in the production line cooperation, and the two sides are combined based on their respective technology and team advantages, it has opened up a new avenue to enhance the independent mass production capacity of MEMS RF devices in China. Sun Chengliang, Chairman of

Minsheng, showed 8-inch BAW filter product

Wuhan Minsheng Chairman Sun Chengliang said: "Thanks to our strategic partner Saiwei Electronics, after more than a year of concerted efforts, we have seen the professionalism and pragmatism of the two teams and are more sympathetic to each other, we are full of confidence in the continued cooperation between the two sides in the future! The Beijing production line is only one of the steps on our way forward, and it is also a key step. Next, we will achieve mass production in accordance with the set goals, win market opportunities as soon as possible, and lay a solid foundation for the localization of BAW filters. Thank you for witnessing the critical moment of Wuhan Minsheng's growth, and please continue to pay attention and support us!" Yang Yunchun, chairman of

Sai Microelectronics, said: "This 8-inch BAW filter joint production line is the result of sincere cooperation between the two sides, and it is also a new cooperation mode jointly created by the two sides, which will be conducive to the realization of independent and controllable production of BAW filters in China. Beijing FAB3 is a representative of Saiwei Electronics's domestic scale production capacity. In recent years, it has continued to increase R & D investment, independently accumulated basic processes, and actively explored the production know-how of various MEMS devices. It welcomes extensive cooperation with MEMS design manufacturers in various fields around the world, especially in China, to contribute to the further development of China's MEMS industry ecology."
