Electrodeposited Copper Foil Applications
Copper foils are suitable for a range of applications, from PCB’s to lithium-ion batteries. Electrodeposited copper foil is one of the most essential components in PCB’s, as the conductive material of the printed circuit board, and also plays an important role as the anode material of the lithium-ion battery.
Electrodeposited Copper Foil Manufacturing Process
Electrodeposited copper foil is manufactured through the deposition of copper ions, onto the cathode drum via electrolysis. In Practice, the foil is produced through continuous rotation of the drum and simultaneous winding of the copper foil as it is released from the drum surface.
