A printed circuit board having an electronic component embedded is disclosed. The printed circuit board has four electrically conductive layers and three core layers formed interleavedly. By properly removing a portion of the printed circuit board, the electronic component can be exposed. It has advantages that the exposed electronic component can be a CCD, CMOS or module. When the devices mentioned are embedded in the printed circuit board, one part of them can be exposed from the printed circuit board for normal functions. The overall thickness of the printed circuit board assembly can be minimized to meet the trend of compact design of electronic products.

A connector for a multilayered board to connect a flat cable to a middle layer of a multilayered board while minimizing the impact due to variations in the dimensional precision and strength of multilayered boards and/or preventing deformation of the multilayered board and improving contact stability. The connector includes a board-side connecting portion and a cable-side connecting portion. The board-side connecting portion includes a column-shaped terminal, and the cable-side connecting portion includes flat terminals. The column-shaped terminal protrudes from the middle layer of the multilayered board in the thickness direction. The flat terminals include resilient contact portions, contacting a side surface portion of the column-shaped terminal from the width direction of the insertion slot in response to insertion of the cable-side connecting portion into the insertion slot.

Abstract:
A signal transmission cable as a signal transmission component includes a laminate including a first thin portion on one of the opposite ends in a first direction and a second thin portion on the other end in the first direction. A portion between the first thin portion and the second thin portion in the laminate is a main line portion. The thickness of the first and second thin portions is thinner than the thickness of the main line portion. The surface on one end in the thickness direction of the laminate defined by the main line portion and the first and second thin portions is a continuous flat surface. A connector for external connection is arranged on the surfaces of the first and second thin portions, on the sides in which each of the thin portions and the main line portion have a difference in level.

A printed circuit board (PCB) includes a stack of core layers disposed one over another, and electrically conductive interconnects extending vertically in the stack. Each of the core layers includes a substrate having opposite major surfaces, an electrically conductive active trace extending along at least one of the major surfaces, and an indicium. The stack also has an exposed edge where the indicia of the layers are together revealed. The indicia provide identifying and/or fiducial information about the PCB.
