The rapid development of communication transmission frequency has put forward higher requirements for the surface roughness of materials, and as an important part of the field of electronic communication, FPC should have low Dk and Df values, and copper foil with low nickel cobalt treatment copper foil, under the premise of meeting the stable etchability, has lower roughness, can effectively maintain the stability of high-frequency signal transmission
New energy vehicles have increasingly high requirements for automation and intellectualization Blackenedrolled copper foil can be used for on-board circuit boards of fine lines, red copper material can meet the requirements of high temperature grain structure stability of on-board IGBT module group, and brass foil is used for battery packs and seat heating devices due to its stable thermal resistance In addition, Guangyuan products also provide LED lamp bracket reflector with copperstrip foil, battery net with copperfoil and line fuse cap with copper belt products
Rolled copper foil has few impurities and high purity, high conductivity, low roughness characteristics, good diamagnetization, high strength under normal conditions, good flexibility in soft state, and can be widely used in the aerospace equipment of power convergence and signal transmission
The miniaturization, integration and high transmission of electronic circuits and control lines make the anti-interference requirements between the signal lines more and more high, and with the expansion of the field of use, the anti-aging properties of materials in harsh environment also put forward higher requirements Copper foil has better electrical and thermal conductivity, and the soft state has better bending formability and compactness By surface functional treatment of the copper foil, Tianhe copper foil has better corrosion resistance in high temperature and high humidity environment, and can be widely used in electronic equipment in the need of heat dissipation, shielding parts
Heat exchanging and liquid cooling of industrial and electronic equipment require high exchange efficiency and reliability of materials By changing the corrosion morphology of Guangyuan microalloying high zinc brass material, the corrosion resistance is improved and the service life of the heat exchange device is improved Pure copper and microalloyed copper materials, through the control organization, maintain high heat conductivity while maintaining high strength, can be used as electronic equipment for soaking plate shell material, meet the high heat flux of soaking plate high integration, miniaturization of the new requirements, can also be used for laptop computer cooling fins and other electronic equipment cooling field
