Patent ID: 8609991

Claim:
A flex-rigid wiring board comprising: a rigid substrate comprising a rigid base material, a first insulation layer formed on the rigid base material, a second insulation layer formed on the first insulation layer, and a conductor layer formed on the first insulation layer; and a flexible substrate aligned with the rigid base material of the rigid substrate in a longitudinal direction of the flexible substrate and having an end portion partially embedded in the rigid substrate, the flexible substrate comprising a conductor layer electrically connected to the conductor layer of the rigid substrate, wherein the flexible substrate has a thickness which is substantially equal to a thickness of the rigid base material of the rigid substrate and has surfaces which are horizontal with respect to surfaces of the rigid base material of the rigid substrate in the longitudinal direction, the rigid substrate comprises at least one connection terminal formed through the second insulation layer and positioned to mount an electronic component and electrically connect the electronic component with the conductor layer of the rigid substrate, and the rigid substrate has a recessed portion configured to accommodate the electronic component and formed on a surface of the rigid substrate such that the recessed portion exposes the at least one connection terminal and a portion of the second insulation layer over the rigid base material of the rigid substrate.
