PRINTED CIRCUIT BOARD HAVING ELECTRONIC COMPONENT EMBEDDED
First Claim
1. A printed circuit board having an electronic component embedded, comprising:
- a first electrically conductive layer;
a first core layer having a portion removed to expose at least a portion of the electronic component and a portion of a second core layer;
the second electrically conductive layer;
a second core layer having an area which is hollow so as to locate the electronic component therein;
a third electrically conductive layer;
a third core layer; and
a fourth electrically conductive layer,wherein a bound pad is formed on a portion of a top surface of the electronic component, a plurality of via holes from the bound pad to the first electrically conductive layer are formed and electrically connected therebetween, each of the electrically conductive layers forms a desired circuit, and at least one side of an exposed top surface of the electronic component is higher than or equal to a side of a top surface of the exposed second core layer neighboring to each other.

Abstract
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.
