Abstract
For use in a printed wiring board, a capacitor, and a method of manufacturing the capacitor. In one embodiment, the capacitor includes: (1) first and second interdigitated finger sets, located on a first layer of the printed wiring board, that employ fringe capacitance to store electrical energy and together form a first capacitor conductor and (2) a second capacitor conductor, located on a second layer of the printed wiring board, that cooperates with the first capacitor conductor to employ plate capacitance to store further electrical energy.
Claims21
For use in a printed wiring board, a capacitor, comprising:
- first and second interdigitated finger sets, located on a first layer of said printed wiring board, that employ fringe capacitance to store electrical energy and together form a first capacitor conductor;
- and
- a second capacitor conductor, located on a second layer of said printed wiring board, that cooperates with said first capacitor conductor to employ plate capacitance to store further electrical energy.
A method of manufacturing a capacitor in a printed wiring board, comprising:
- forming first and second interdigitated finger sets on a first layer of said printed wiring board, said first and second interdigitated finger sets employing fringe capacitance to store electrical energy and together form a first capacitor conductor;
- and
- forming a second capacitor conductor on a second layer of said printed wiring board, said second capacitor conductor cooperating with said first capacitor conductor to employ plate capacitance to store further electrical energy.
A jack assembly, comprising:
- a lead frame;
- finger stock located in said lead frame;
- a printed wiring board coupled to said lead frame and receiving said finger stock;
- and
- at least one capacitor, located in said printed wiring board and coupled to said finger stock, each of said at least one capacitor including:
- first and second interdigitated finger sets, located on a first layer of said printed wiring board, that employ fringe capacitance to store electrical energy and together form a first capacitor conductor and
- a second capacitor conductor, located on a second layer of said printed wiring board, that cooperates with said first capacitor conductor to employ plate capacitance to store further electrical energy.
