The role of solder wire

Whether it is in the chip core of personal computers, or in the emerging electric vehicles and high-precision semiconductors, the figure of "tin beads" appears to be everywhere. Take a computer's CPU as an example, where each integrated circuit is connected by thousands of delicate solder beads. These tiny tin particles are not only the cornerstone of the manufacture of various home appliances and electronic equipment, but also play a vital role in cutting-edge industries such as photovoltaics and new energy vehicles. Known as the "soul of industry", the importance of tin is self-evident, it meets people's daily needs and has become an indispensable element for national development. Li Ruixuan, sales director of the market operation center of Yunxi New Materials Co., Ltd., revealed that tin-based new materials are widely used in many high-tech fields such as electronics, steel, automobile manufacturing, aerospace, new energy and machinery manufacturing.

Recently, I visited the production base of Yunxi New Materials Co., Ltd., and I was greeted by rows of advanced equipment that are constantly producing ultra-fine tin filaments as delicate as hair. In these containers, which are slightly larger than everyday cruet bottles, there are millions of solder ball particles piled up...... These high-end tin processing products dominate the domestic market and have gradually entered the international market. Behind all this, it is inseparable from the company's unremitting efforts and resource investment in "R&D and innovation", "process upgrading" and "talent training", which continue to promote the growth and expansion of new productivity.

One of the "innovative elements": extremely delicate tin fiber

Stepping into the tin wire processing area, you will be greeted by a compact production site. A non-stop machine is constantly producing tiny wires thinner than a human hair, tiny wires that would be almost imperceptible if it weren't for the refraction of light. Through the transparent window, it can be clearly identified that this is a professional production line specializing in the production of ultra-fine solder wire of φ0.1mm grade.

Through dozens of exquisite processes such as smelting solder alloys, ingot molding, extrusion and drawing, and precision fine drawing, this delicate metal fiber has finally appeared in the public eye. In our everyday products, from switches and mobile phones to remote controls, many electronic products rely on the silent support of this solder wire. In the field of aerospace and high-precision electronic product manufacturing, solder wire plays a vital role. Zhang Chenghai, the leader of the company's business department, revealed that through continuous R&D and innovation, we have successfully developed the smallest ultra-fine solder wire in the industry, which represents a major technological progress in the field of deep processing of cloud tin solder wire. This marks another important leap in the processing technology of tin-based new materials. Looking forward to the future, the company will continue to deepen the processing technology of ultra-fine solder wire, improve the research and development of high-reliability solder wire alloys, upgrade production equipment, and strive to create high-quality, high-value-added high-end solder wire products.

In order to ensure the perfect docking of products and market demand, and keep up with the development trend of the industry, our R&D team has made every effort to build a professional team of scientific research elites. With meticulous market analysis, comprehensive information integration, rich experimental exploration and the crystallization of the team's wisdom, the team has successfully launched a number of innovative products such as special flux for aluminum-based solder wire, automotive solder balls suitable for new energy laser welding, low-melting point solder for photovoltaic welding strips, dioctyl tin dichloride, and dioctyl tin oxide, and achieved significant technological breakthroughs. In 2023, our R&D investment increased by 28.2%, implemented 130 science and technology projects, and received more than 40 million yuan in policy support. At the same time, we have achieved the sales of more than 3,700 tons of new products, and the sales revenue has increased by 480 million yuan.

Increment 2: The tin beads used for welding are crystal clear

Although the glass container is not as large as the usual spice bottle at home, it contains about 5 million solder beads, and the heaviness of the hand is palpable. These insignificant tin beads are ubiquitous in our daily lives.

"We have developed and perfected our production processes and equipment based on the accumulation of practical production experience and continuous experiments and tests." In terms of new technology optimization, the company is committed to the research and development of intelligent preparation process of chip packaging solder balls, designed and manufactured an automatic roundness screening machine for solder balls, introduced a new production line and complete sets of equipment, and replaced the expensive imported ultrasonic power supply. These initiatives have significantly increased the degree of automation in the production of solder balls, enabling intelligent production through one-click process parameter setting and automatic adjustment. With the same staffing, production capacity increased by 332%.

After detailed market research, the company has built a production line of more than 1,000 different specifications of tin products including nine series of wires, wires, powders, pastes, etc. At the same time, we have also expanded our inorganic tin and organotin product lines, covering 28 products with a total of 45 tin chemical products of different specifications. With an annual output of 66,000 tons, the sales network has covered the entire domestic market, and successfully entered the European and American markets, winning wide recognition and high praise from consumers at home and abroad.
