On September 6th, three astronauts, Nie Haisheng, Liu Boming, and Tang Hongbo, sent a cordial message to young people across the country in the Tianhe core module of the Chinese Space Station. The Tianhe core module, which accompanied the three astronauts in orbit, bears the shining mark of “Made in Sanmenxia”. 

Recently, the reporter learned from Jinyuan Zhaohui Copper Industry Co., Ltd. that the company had confirmed with the Fifth China Academy of Space Technology that the flat inter-board cable at the edge of the flexible solar cell wing of the Tianhe core module used the rolled copper foil produced by the company. It is learned that the main function of the cable is to collect the current generated by each flexible solar panel. After the current is collected, it is transmitted to the space station for the daily scientific work and daily life of the astronauts in the cabin.

According to the person in charge, the company is vigorously advancing the improvement of copper foil performance and expanding the application of copper foil and other technical problems, while speeding up the research and development and production of alloy foil. The company has invested a total of more than 40 million yuan, introduced more than ten equipment such as the cupping machine, scanning electron microscope, ICP automatic circulating electroplating solution tester, and implemented high-precision technical transformation for original production equipment of foil rolling, degreasing, and surface treatment, etc. At present, it has developed a blackened rolled copper foil product for flexible copper clad laminate that meets the needs of the high-end market and cutting-edge science and technology, and continues to make strong contributions to the construction of national strength in space and Sanmenxia’s high-quality economic and social development through scientific and technological innovation.
