Abstract:
A component-embedded substrate includes an electrically insulating base (11) of resin, an electric or electronic embedded component (8) and a dummy embedded component (7) both embedded in the insulating base (11), a conductor pattern (18) formed on at least one side of the insulating base (11) and connected directly to or indirectly via a connection layer (6) to the embedded component (8) and the dummy embedded component (7), and a mark (10) formed on a surface of the dummy embedded component (7) and used as a reference when the conductor pattern (18) is formed, whereby positional accuracy of the conductor pattern (18) relative to the embedded component (8) can be improved.
Abstract:
The substrate gap supporter (30) according to one embodiment of the present invention comprises a body (31) having a hexahedron shape and made of an insulator, metal foils (32a) and (32b) installed on opposite side surfaces of the body (31) to expose the upper portions of both side surfaces and cover the lower portions of both side surfaces, and a substrate (210) attached to the bottom surface of the body (31). According to the present invention, the gap supporter can be made through an automated process, thus precisely controlling size. Since the gap supporter is attached to the surface of the substrate, there is little possibility for a height difference to occur. And also, because the gap supporter can be installed in an automated process, it is suitable for a mass production process.

Abstract:
In a circuit board disposed in parallel to a fixing plane, a guard spacer (abutting member) is disposed on a multi-layer printed circuit board on the side of the fixing plane to suppress deformation of the multi-layer printed circuit board to prevent short circuit if an impact is applied to the circuit board. The guard spacer may be a dummy electronic component or a plate member. An image display using the circuit board is also disclosed.
