Abstract
A flexible copper-clad laminate for a vehicle LED lamp is provided and includes a copper-clad layer and a composite layer that are laminated. The composite layer includes a polyimide layer and thermoplastic polyimide layers. An outermost layer of the composite layer is formed as a thermoplastic polyimide layer. A total thickness of the thermoplastic polyimide layers and an entire thickness of the polyimide layer with respect to a total thickness of the composite layer is about 10 to 50% and 50 to 90%, respectively. The total thickness of the thermoplastic polyimide layers and the entire thickness of the polyimide layer with respect to the thickness of the composite layer is about 20 to 40% and 60 to 80%, respectively. A thickness of the copper-clad layer is about 30 to 80 μm, and the total thickness of the composite layer is about 10 to 15 μm.
