Method for Manufacturing Substrate Having Electric Component
A simple method of producing an electric component-mounted substrate having a cavity structure is provided. Because a supporting substrate 20 and electric components 31 and 32 are connected together to a first face of a base substrate 10, the number of steps for the connection is reduced to shorten the producing time. When electric components 32 and 33 are to be connected to a second face 14, the base substrate 10 is supported by the supporting substrate 20, and the electric components 31 and 32 and connected to the first face 13 do not contact a processing table 51 and therefore they undergo no damage. Thus, according to the present invention, an electric component-mounted substrate 1 having high reliability can be produced in a short time.
