Our high-quality copper foils support all commonly used fabrication processes and substrate chemistries including FR-4 and polyimide. Foil types include IPC-4563 type-3 High-Temperature Elongation (HTE) copper, high bond-strength copper, protective-coated copper foils, and single-sided and double-sided foils with aluminum layer. Their high surface purity and uniformity ensure consistent adhesion, for maximum production yield.
