Abstract:
1. A method of making a capacitive substrate, said method comprising: providing a first capacitive dielectric layer having first and second opposing sides; providing first and second conductors on said first and second opposing sides of said first capacitive dielectric layer, respectively; screen printing a second capacitive dielectric layer onto said first conductor on said first opposing side of said first capacitive dielectric layer, said second capacitive dielectric layer including nano-particles and/or micro-particles therein; providing a third conductor on said second capacitive dielectric layer on said first conductor; forming a first thru-hole electrical connection between said second and third conductors; and forming a second thru-hole electrical connection between said first conductor and a fourth conductor, said first and second conductors and said first capacitive dielectric layer forming a first capacitor and said first and third conductors and said second capacitive dielectric layer forming a second capacitor when said capacitive substrate is operational.
