    Abstract: A planarized cover layer structure of a flexible circuit board includes an insulation layer bonded through a first adhesive layer to a surface of each one of conductive signal lines laid on a substrate of a flexible circuit board. Separation areas respectively formed between adjacent ones of the conductive signal lines are each formed with a filling layer, so that the filling layer provides the first adhesive layer with a planarization height in the separation areas and the planarization height is substantially equal to the height of the conductive signal lines. The filling layer can alternatively be of a height that is higher than the surface of the conductor layer by a covering height so that the first adhesive layer has a planarization height in the separation areas and the planarization height is substantially equal to the sum of the height of the conductive signal lines and the covering height.

    Abstract: Disclosed are a printed circuit board and a method for manufacturing the same. The printed circuit board includes a core insulating layer, at least one via formed through the core insulating layer, an inner circuit layer buried in the core insulating layer, and an outer circuit layer on a top surface or a bottom surface of the core insulating layer, wherein the via includes a center part having a first width and a contact part having a second width, the contact part makes contact with a surface of the core insulating layer, and the first width is larger than the second width. The inner circuit layer and the via are simultaneously formed so that the process steps are reduced. Since odd circuit layers are provided, the printed circuit board has a light and slim structure.
