Copper Foil

Copper Foil is available types:

• Electrodeposited Copper Foil

Electrodeposited copper foil, also known as electrolytic copper foil, is produced by electroplating copper onto a rolling drum in a highly controlled manner. This type of copper foil has uniform thickness and excellent electrical conductivity, making it ideal for high-performance electronic applications.

• Rolled Annealed (RA) Copper Foil

Rolled Annealed copper foil is produced through a rolling and annealing process, as described earlier. It offers good flexibility and is commonly used in flexible printed circuit boards (PCBs) and other applications where flexibility is required.

• High-Temperature Rolled Annealed (HTRA) Copper Foil

High-Temperature Rolled Annealed copper foil is similar to RA copper foil but undergoes additional heat treatment to enhance its resistance to high temperatures. This type of copper foil is used in applications that involve exposure to elevated temperatures.

• Ultra-Thin Copper Foil

Ultra-thin copper foil is an extremely thin variant used in specialized applications where space is limited, such as in RFID tags and smart cards.
