Copper foil is widely used in a variety of fields: It is a crucial component in manufacturing PCBs, forming the conductive traces and interconnections. It's also used in mobile phones, digital cameras, and IT devices. It functions as a current collector (anode material) in lithium-ion batteries, enhancing performance by providing a conductive pathway for electrons. Used to line enclosures or wrap components in electronic devices to prevent interference. In stained glass work, copper foil tape is used to wrap the edges of individual glass pieces so they can be soldered together. It is also used for general crafting, embossing, and architectural accents. It is processed into various parts like gaskets and washers and used in electrical transformers, radiators, and the automotive and construction industries.
