What is Electrolytic Copper Foil?
Electrolytic copper foil is a thin layer of copper produced through the process of electrodeposition. This technique allows for the creation of ultra-thin, high-purity copper sheets, typically ranging in thickness from a few microns to several dozen microns. These foils are primarily used for their excellent electrical conductivity, thermal performance, and mechanical strength. The ability to customize thickness and surface properties also makes them ideal for various high-performance applications.
