Method for manufacturing circuit board
A manufacturing method of a circuit board is provided. A first carrier board included a substrate and a first conductive layer is provided, and the first conductive layer is located on a first surface of the substrate. A stainless steel layer is sputtered on the first conductive layer. An insulating layer is formed to cover a peripheral region of the stainless steel layer and expose a central region. A circuit structure layer is formed on the central region exposed by the insulating layer. A bottom surface of the circuit structure layer is connected to the first carrier board. A transferring procedure is performed to adhere a top surface of the circuit structure layer onto an adhesive layer of a second carrier board. The first carrier board is separated with the circuit structure layer to transfer the circuit structure layer onto the second carrier board, and expose the bottom surface of the circuit structure layer. The manufacturing method of the circuit board of the present invention is safer and simpler, may effectively reduce the manufacturing costs and improve the product yields.
