Flexible substrate |
摘要 |
A flexible substrate includes a circuit board, a flexible heat-dissipating structure and an adhesive. The circuit board has a substrate and a circuit layer formed on a top surface of the substrate, and the flexible heat-dissipating structure has a flexible supporting plate and a flexible heat-dissipating metal layer formed on a surface of the flexible supporting plate. The flexible heat-dissipating metal layer of the flexible heat-dissipating structure is connected with a bottom surface of the substrate by the adhesive. The circuit layer and the flexible heat-dissipating metal layer are made of same material. |

1. A flexible substrate includes:
a circuit board comprising a substrate and a circuit layer, wherein the substrate comprises a top surface and a bottom surface, the circuit layer is formed on the top surface, and the top surface comprises a chip-disposing area; a flexible heat-dissipating structure connected with the bottom surface of the substrate comprising a flexible supporting plate, a flexible heat-dissipating metal layer and a protecting layer, wherein the flexible supporting plate comprises a surface facing toward the bottom surface of the substrate and a side wall, the flexible heat-dissipating metal layer is formed on the surface of the flexible supporting plate and located underneath the chip-disposing area, the flexible heat-dissipating metal layer comprises a lateral surface coplanar with the side wall of the flexible supporting plate, and the protecting layer covers the lateral surface of the flexible heat-dissipating metal layer and the bottom surface of the substrate, wherein the substrate and the flexible supporting plate are made of same material; and an adhesive formed on the flexible heat-dissipating metal layer, wherein the flexible heat-dissipating metal layer is connected with the bottom surface of the substrate by the adhesive. |
