The black halogen-free P1(Polyimide) copper-clad laminate (CCL) integrates multiple advantages; it is halogen-free and environmentally friendly, inherits the high-temperature resistance and excellent electrical properties of PI material, and also achieves a light-shielding effect by virtue of its black characteristic.
