Abstract:
1. A method for manufacturing a printed circuit board (PCB) having different thicknesses in different areas, comprising: providing a first substrate, the first substrate having two first lateral unwanted portions bounded two imaginary boundary lines, defining two slots in the first substrate, the slots running between the imaginary boundary lines, the first substrate having an intermediate unwanted portions bounded by the slots and the imaginary boundary lines; providing a binder layer having a first surface and an opposite second surface, the binder layer having a through opening defined therein, and two inner side surfaces in and at opposite sides of the through opening; attaching the first substrate to the first surface of the binder layer with the slots respectively aligned with the inner side surfaces of the binder layer; providing a second substrate, the second substrate having two second lateral unwanted portions; attaching the second substrate to the second surface of the binder layer with the second lateral unwanted portions respectively aligned with the first lateral unwanted portions; filling the through opening and the slots using a filling material thereby obtaining a semifinished PCB board; cutting the semi-finished PCB board along the imaginary boundary lines to remove the first and second lateral unwanted portions; and removing the intermediate unwanted portion and the filling material.
