In July 2023, during an inspection tour in Sichuan, General Secretary Xi Jinping emphasized the province's potential in scientific and technological innovation and the transformation of scientific and technological achievements. Sichuan is home to numerous universities, research institutions, and a complete industrial system, all of which provide a solid foundation for its scientific and technological innovation. In the Suining Economic Development Zone, Sichuan Winner Special Electronic Materials Co., Ltd. has closely cooperated with universities. After numerous R & D experiments, it has successfully broken through foreign technological monopolies and solved the problem of uneven distribution of the palladium plating layer on bonding wires. This important breakthrough marks a solid step forward for domestic bonding wires towards the high - end field.
At 5 p.m. every day, Venal Special Materials Company enters the busiest time of the day. They need to pack all the 4,000 kilometers of bonding wires produced that day and ship them across the country. These bonding wires, as thin as a hair, are one of the four essential raw materials in the semiconductor packaging industry.
Since 2009, Venal has embarked on a journey of R & D and production of bonding wires. However, copper wires are prone to oxidation and have a short lifespan, mainly suitable for low - end applications; while gold and silver wires face challenges in market promotion due to their high costs. To break through this dilemma, Venal has cooperated with expert teams from Chongqing University of Technology and Sichuan University since 2020 to jointly carry out the R & D of high - end bonding wires such as palladium - plated copper wires and gold alloy wires.
Palladium - plated copper wires are traditional copper wires covered with a layer of palladium to extend their service life. Although the palladium - plating process seems simple, precisely controlling the thickness and uniformity of the palladium layer to improve product quality is a key technology. For a long time, this technology has been monopolized by foreign companies.
The cooperation between Sichuan Winner Special Electronic Materials Co., Ltd. and the expert team of Chongqing University of Technology has brought a turning point. The theoretical support and guidance from universities have saved the enterprise a lot of R & D time, thus seizing the initiative in the market. With the enterprise's complete production line and the university's testing equipment and talent team, the two sides jointly aim at the world's top bonding wire manufacturers and continuously improve the quality of domestic palladium - plated copper wires. In terms of the uniformity of palladium distribution, seven rounds of joint experiments have been carried out. Now, this technology has achieved mass production and reached cooperation intentions with well - known domestic enterprises.
"Currently, our products are in short supply. Each enterprise can obtain a maximum supply for only two to three days at a time," revealed Wang Hui, a business assistant in the company's business department. With a major breakthrough in the palladium distribution technology, Venal's annual output of palladium - plated copper wires reached over 700,000 kilometers in 2023. This not only meets the urgent demand of the domestic semiconductor packaging industry for high - quality bonding wires but also wins wide market recognition with affordable prices.
"With the deepening of R & D, our products have moved from low - end to high - end," said Zeng Guangwei, the company's general manager, proudly. Nowadays, customers are placing additional orders and showing an increasingly strong willingness to cooperate. The cooperation between Winner and universities is a model of technology enabling production, demonstrating the earnest entrustment of the General Secretary. Looking to the future, Winner's Phase II project is expected to be fully operational in May 2024. By then, the monthly output of bonding wires will exceed 300,000 kilometers, further consolidating the enterprise's leading position in the industry.
