On November 28th, the "Development of Electrolytic Copper Foil with Very Low Profile for 5G High-frequency High-speed Antenna" undertaken by SDJB Electronic Materials Technology Company won the 5G pilot demonstration project. The product of this project has the characteristics of extremely low surface profile, excellent anti-stripping performance and excellent high temperature elongation rate. It is widely used in 5G RF antennas, radar, satellite navigation and other fields to meet the high frequency of signal transmission and reduce signal transmission. Losses and other requirements.
The research and development of the project will realize the localization of this type of electrolytic copper foil, break the technical monopoly of foreign (foreign-funded) manufacturers, and fill the domestic gap, which is the first domestic initiative. The localization of this strategic new material not only has the significance of competing for new markets at home and abroad, but also has a long-term relationship with the strategic needs of the development of new national military equipment and the maintenance of national security.
