Abstract
A wiring board with dual stiffeners and integrated dual routing circuitries is characterized in that first and second routing circuitries are positioned within and beyond a through opening of a first stiffener, respectively, and an array of vertical connecting channels are disposed on the second routing circuitry and laterally surrounded by a second stiffener. The mechanical robustness of the first and second stiffeners can prevent the wiring board from warping. The vertical connecting channels can offer electrical contacts for next-level connection. The first routing circuitry, positioned within the through opening of the first stiffener, can provide primary fan-out routing, whereas the second routing circuitry not only provides further fan-out wiring structure for the first routing circuitry, but also mechanically binds the first routing circuitry with the first stiffener.
