<p>A rigid-flex printed circuit board with a novel basestock composite isdisclosed. The basestock composite is composed of a core insulating layersandwiched between two conductive sheets. The core insulating layer has acutout region that is filled with a flexible insert, wherein the cutout region hassubstantially vertical sidewalls. Furthermore, the sidewalls of the cutout region donot have a step profile.</p> |
