TISCO solved the problem of “stuck neck”

TISCO solved the problem of “stuck neck”

After nearly three years of systematic research and continuous improvement, TISCO achieved stable supply of precipitation hardening SUS630 stainless steel cold-rolled plate products in batches, becoming the only domestic company that can provide such products. This product solves the “stuck neck” problem of key basic materials in my country’s electronic circuit industry, and helps China’s electronic circuit printed circuit board (hereinafter referred to as “PCB”) industry to move towards high-end.

PCB is a carrier that integrates electronic components and realizes control functions, commonly known as the “mother of electronic products”. PCB is the focus of scientific and technological competition in various countries and belongs to the national strategic technical field. Its downstream applications cover important fields such as 5G, automotive electronics, consumer electronics, industrial control equipment, medical electronics, aerospace and military products, and are the core content of “Made in China 2025” . In recent years, my country has vigorously developed the PCB industry, and has now become the world’s largest PCB production area. Products are gradually upgraded from the low-end to the high-end direction.

Precipitation hardening stainless steel SUS630 is widely used in the thermal lamination process of printed circuit boards. It is one of the indispensable key basic materials for the production of electronic circuits. Its quality level has the most direct impact on the safety and stability of electronic products. Technology and procurement channels have been mastered by foreign countries for many years. With the rise of high-tech industries such as 5G, the Internet of Things, smart medical care, autonomous driving, and wearable devices, the electronic circuit industry’s demand for SUS630 materials has increased significantly, and the problem of “stuck necks” has become increasingly prominent. The production, sales and research team of Taiyuan Iron and Steel Co., Ltd. and related production companies jointly developed the product, accurately designed unique designs based on user needs, and strictly implemented the entire process of refined quality control. At present, the linear expansion coefficient, flatness, same board difference, surface quality, and surface roughness of such products of Taiyuan Iron and Steel Co., Ltd. all meet the stringent requirements of users. They have successfully moved from the laboratory to the market and achieved stable supply in batches.

In the future, TISCO will continue to carry forward the spirit of craftsmanship and be a pioneer in innovation and development. It will take the development of key basic materials for the country’s “chuck neck” as its own responsibility, and will not forget the original intention of “serving the country by industry”, and will continue to demonstrate TISCO’s hardness in the development and manufacturing of core materials. nuclear power.
