The document describes four series of aluminum-based CCL (YGA-1, YGA-2, YGA-3, YGA-4) that have advantages like high heat dissipation and electromagnetic shielding. Each series comes in multiple models with varying insulation layer thicknesses and properties. All series exhibit high peel strength, low resistivity and dissipation factor, high breakdown voltage, flame retardancy, and can withstand thermal stress testing without delaminating. The materials are suitable for applications like audio equipment, power supplies, automotive electronics, and LED lighting.
