  • Patent number: 8091218
    Abstract: Provided is a bending rigid printed wiring board which facilitate the mounting of electric parts (realization of a high producibility and high assemblability substrate circuit) and enables spaces to be saved and which can be easily manufactured. That is, provided is a bending rigid printed wiring board, which is characterized in that a heat resistant resin layer is laminated on a front surface of a hard core material provided so as to contain a gap portion and also on a top surface of the gap portion, in that a heat resistant resin layer is laminated on a rear surface of the core material except the gap portion, in that a conductor layer is laminated and firmly fixed via the heat resistant resin layers and in that the conductor layer is etched, whereby a circuit is formed.

  • Publication number: 20100294544
    Abstract: This invention provides a bending-type rigid printed wiring board that can easily realize mounting of electric components (can realize a plated circuit having high productivity and assembling properties), can realize space saving, and can realize easy production. The bending-type rigid printed wiring board comprises a hard cure material (1) with a space part (1A) inserted thereinto. A heat-resistant resin layer (31) is stacked on the surface of the hard core material (1) and, at the same time, on the upper surface of the space part (1A). A heat-resistant resin layer (32) is stacked on the backside of the core material (1) except for the space part (1A). Further, a conductor layer (4) is stacked and fixed through the heat-resistant resin layers (31, 32). The conductor layer (4) has been etched to form a circuit.
