Abstract

Disclosed is a method on forming multiple discrete devices (resistors, capacitors, inductors) in one plated-thru hole so that they are placed optimally in a performance point of view on a PCB (printed circuit board). The invention consists in filling the plated thru-hole with one or several materials having appropriate properties in order to create different value of reference (Ohm, Farad, Henry).
