Abstract
A method and apparatus for implementing customized printed circuit board (PCB) via creation through use of magnetic capture pads. At least one magnetic capture pad is rendered before aqueous seed and plate processing in the PCB manufacture. The magnetic capture pad selectively provides seed material rendering copper in at least one selected region of the via.
Claims13
A method for implementing enhanced customized printed circuit board (PCB) via creation during printed circuit board (PCB) manufacturing comprising:
- providing a printed circuit board (PCB);
- forming a via extending through the printed circuit board (PCB);
- rendering at least one magnetic pad into the via before aqueous seed and plate processing in the PCB manufacture;
- performing PCB aqueous seed and plate processing, and said at least one magnetic pad selectively rendering copper in at least one selected region of the via.
