Abstract:
1. A structure for creating a printed circuit board with stepped thickness comprising: a plurality of core layers; a plurality of wiring layers respectively supported by said plurality of core layers; said plurality of core layers being laminated together for forming the printed circuit board; at least one reduced thickness area of the printed circuit board; said at least one reduced thickness area disposed adjacent a perimeter portion of the printed circuit board, said at least one reduced thickness area defining an edge connector including a plurality of edge connector electrically conductive tabs carried on predefined layers of said plurality of core layers; a plurality of components being assembled on the printed circuit board; and said at least one reduced thickness area being formed using a non-laminating breakaway material layer selectively positioned between predefined layers of said plurality of core layers and spaced apart from said predefined wiring layers supported by said predefined layers of said plurality of core layers and removed to define said at least one reduced thickness area and said edge connector including said plurality of edge connector electrically conductive tabs; said non-laminating breakaway material layer preventing adhesion between a respective adjacent portion of said predefined layers of said plurality of core layers and said plurality of edge connector electrically conductive tabs.
