The 50-micron copper foil comes in various types, each tailored to specific applications and industry needs. These types include:
Electrolytic Copper Foil (ECF)
Electrolytic copper foil, also known as copper-clad foil, is produced by an electrolysis method. In this process, a thick copper sheet is placed in an electrolyte solution with a conductive object. The copper is then deposited onto the surface in a thin layer. This process is conducted by machine and can produce sheets of copper that are 1/8 inches up to 1/2 inch thick, ready to be polished and turned into more delicate sheets of copper foil for various applications.
Rolled Copper Foil (RCF)
Unlike electrolytic foil, rolled copper foil is made by physically rolling out pure copper into thin sheets. This method is primarily used for producing thicker sheets of copper foil, but it can also create thinner ones in cases where superior quality and mechanical properties are required.
Hybrid Copper Foil
Hybrid copper foil incorporates other metal layers or materials into the design. It may have, for instance, a thin layer of gold or silver on top of the copper for special applications. These may also be polymer materials that improve strength or flexibility.
High-Performance Copper Foil
High-performance copper foil is developed for advanced technologies. This includes very thin versions, stamps, or treated with heat and chemical-resistant coatings. These types are typically used in high-tech electronics, aerospace, or medical devices.
