Abstract
The invention relates to a printed circuit board having front and rear sides, each side being provided thereon with a mesh-like conductor pattern consisting of two crossing sets of plural metal traces. A through hole passing through the board at every second crossing point of the traces in each direction of the traces on each side of the board.
Claims2
A printed circuit board comprising a board having front and rear sides, each said side being provided thereon with a mesh-like conductor pattern consisting of two crossing sets of plural parallel metal conductor traces, the respective sets of conductor traces on the front and rear sides corresponding with one another, wherein a through hole passing through said board from the front to the rear side thereof is provided at every second crossing point of the conductor traces in each direction of the conductor traces on each side of the board, each said hole being plated on its inside edge, the plating of each hole being connected with the respective crossing conductor traces at its respective location on both the front and rear sides of the board, said holes conductively connecting the respective crossing conductors on the front and rear sides of the board to one another, said conductor traces selectively severable on each side of the board for isolating selected holes from their respective corssing conductor traces.
A method for producing a printed circuit board comprising:
- providing a mesh-like pattern of conductors on front and rear sides of a board, the mesh-like pattern consisting of two crossing sets of plural parallel metal conductor traces, the respective sets of conductor traces on the front and rear sides of the board corresponding with one another;
- providing a through hole passing through said board from the front to the rear side thereof at every second crossing point of the conductor traces in each direction of the conductor traces on each side of the board,
- plating each said hole from the front to rear side of the board,
- conductively connecting the plating of each said hole with the respective crossing conductor traces at its respective location on both the front and rear sides of the board, said holes conductively connecting the respective crossing conductor traces, on the front and rear sides of the board to one another, and
- severing selected ones of said conductor traces on each side of the board for isolating selected ones of said holes from their respective crossing conductor traces.
