WHAT IS THE EXTRA THICK ELECTROLYTIC COPPER FOIL FOR PCB MARKET?

Extra thick electrolytic copper foil is a specialized material used in printed circuit board (PCB) manufacturing, typically ranging from 105μm to over 500μm in thickness. These foils provide enhanced current-carrying capacity and thermal dissipation, making them essential for high-power applications such as electric vehicle components, power distribution systems, and industrial equipment. The 105μm segment dominates due to its optimal balance between conductivity and flexibility, preferred for high-frequency applications where signal integrity is critical, and offers better thermal management compared to thinner variants.
