ED COPPER FOILS

  • [HTE] High Elongation ED Copper Foil

    [HTE] High Elongation ED Copper Foil

    HTE, high temperature and elongation copper foil produced by CIVEN METAL has excellent resistance to high temperatures and high ductility. The copper foil does not oxidize or change color at high temperatures, and its good ductility makes it easy to laminate with other materials. The copper foil produced by the electrolysis process has a very clean surface and a flat sheet shape. The copper foil itself is roughened on one side, which makes it easier to adhere to other materials. The overall purity of the copper foil is very high, and it has excellent electrical and thermal conductivity. In order to meet the needs of our customers, we can provide not only rolls of copper foil, but also customized slicing services.

  • [BCF] Battery ED Copper Foil

    [BCF] Battery ED Copper Foil

    BCF, battery copper foil for batteries is a copper foil developed and produced by CIVEN METAL specifically for the lithium battery manufacturing industry. This electrolytic copper foil has the advantages of high purity, low impurities, good surface finish, flat surface, uniform tension, and easy coating. With higher purity and better hydrophilic, the electrolytic copper foil for batteries can effectively increase the charge and discharge times and extend the cycle life of batteries. At the same time, CIVEN METAL can slit according to customer’s requirements to meet customer’s material needs for different battery products.

  • [VLP] Very Low Profile ED Copper Foil

    [VLP] Very Low Profile ED Copper Foil

    VLP, very low profile electrolytic copper foil produced by CIVEN METAL has the characteristics of low roughness and high peel strength. The copper foil produced by the electrolysis process has the advantages of high purity, low impurities, smooth surface, flat board shape, and large width. The electrolytic copper foil can be better laminated with other materials after roughening on one side, and it is not easy to peel off.

  • [RTF] Reverse Treated ED Copper Foil

    [RTF] Reverse Treated ED Copper Foil

    RTF, reverse treated electrolytic copper foil is a copper foil that has been roughened to varying degrees on both sides. This strengthens the peel strength of both sides of the copper foil, making it easier to use as an intermediate layer for bonding to other materials. Moreover, the different levels of treatment on both sides of the copper foil make it easier to etch the thinner side of the roughened layer. In the process of making a printed circuit board (PCB) panel, the treated side of the copper is applied to the dielectric material. The treated drum side is rougher than the other side, which constitutes a greater adhesion to the dielectric. This is the main advantage over standard electrolytic copper. The matte side does not require any mechanical or chemical treatment prior to the application of photoresist. It is already rough enough to have good laminating resist adhesion.

  • ED Copper Foils for FPC

    ED Copper Foils for FPC

    FCF, flexible copper foil is specially developed and manufactured for the FPC industry (FCCL). This electrolytic copper foil has better ductility, lower roughness and better peel strength than other copper foils. At the same time, the surface finish and fineness of the copper foil is better and the folding resistance is also better than similar copper foil products. Since this copper foil is based on the electrolytic process, it does not contain grease, which makes it easier to be combined with TPI materials at high temperatures.

  • Shielded ED Copper Foils

    Shielded ED Copper Foils

    STD standard copper foil produced by CIVEN METAL not only has good electrical conductivity because of the high purity of copper, but also is easy to etch and can effectively shield electromagnetic signals and microwave interference. The electrolytic production process allows for a maximum width of 1.2 meters or more, allowing for flexible applications in a wide range of fields. The copper foil itself has a very flat shape and can be perfectly molded to other materials. The copper foil is also resistant to high-temperature oxidation and corrosion, making it suitable for use in harsh environments or for products with strict material life requirements.

  • Super Thick ED Copper Foils

    Super Thick ED Copper Foils

    The ultra-thick low-profile electrolytic copper foil produced by CIVEN METAL is not only customizable in terms of copper foil thickness, but also features low roughness and high separation strength, and the rough surface is not easy to fall off powder. We can also provide slicing service according to customers’ requirements.
