Abstract:
1. A flex-rigid wiring board comprising: a flexible printed wiring board having first and second ends, and comprising a first conductive layer; a rigid printed wiring board having a rigid base material, an insulation layer over the rigid base material and a second conductive layer formed over the insulation layer, wherein the insulation layer covering at least a portion of said first end of the flexible printed wiring board and at least a portion of the rigid base material while exposing at least a portion of the flexible printed wiring board, and the first conductive layer and the second conductive layer are connected through a plated metallic layer penetrating through the insulation layer and through a portion of the flexible printed wiring board; a connection terminal formed on a surface of the rigid printed wiring board and configured to mount an integrated circuit processing chip; another rigid printed wiring board connected to said second end of the flexible printed wiring board and having another surface which faces a same direction as said surface of the rigid printed wiring board; and another connection terminal formed on said another surface of the another rigid printed wiring board and configured to mount an integrated circuit memory chip, the another connection terminal being electrically connected to the first conductive layer of the flexible printed wiring board such that the connection terminal of the rigid wiring board is electrically connected to the another connection terminal of the another rigid wiring board.
