Taiyuan Iron and Steel Co., Ltd. realizes mass production of stainless cold rolled sheets for electric circuits
After nearly three years of systematic research and continuous improvement, TISCO has achieved a stable supply of precipitation hardening SUS630 stainless steel cold rolled sheets in batches, becoming the only company in China 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 for integrating electronic components and realizing 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 technology field. Its downstream applications cover important fields such as 5G, automotive electronics, consumer electronics, industrial control equipment, and medical electronics.
It is the core content of “Made in China 2025”. In recent years, my country has vigorously developed the PCB industry, and it has now become the world’s largest PCB production area.
Precipitation hardening stainless steel SUS630 is widely used in the thermal lamination 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, Internet of Things, smart medical care, autonomous driving, and wearable devices, the demand for SUS630 materials in the electronic circuit industry has grown significantly, and the problem of “stuck neck” has become increasingly prominent. The production, sales, and research team of TISCO cooperated with relevant production enterprises to jointly develop this product and carried out a unique design precisely based on user needs, and strictly implemented the whole process of refined quality control.
At present, the linear expansion coefficient, flatness, the difference between the same plate, surface quality and surface roughness of TISCO products of this type all meet the strict requirements of users, and 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, be the vanguard of innovation and development, take the development of key basic materials for the country’s “stuck neck” as its own responsibility, not forget the original intention of “serving the country by industry”, and continue to demonstrate the strength of TISCO in the R&D and manufacturing of core materials. nuclear power.
