About Us
Copper foil is widely used in lead frame packaging, especially for power device packaging. The lead frame provides structural support and electrical connection for the chip, requiring materials with high conductivity and good thermal conductivity. Copper foil meets these requirements, effectively reducing packaging costs while improving thermal dissipation and electrical performance.
