PRINTED CIRCUIT BOARD WITH STACKED PASSIVE COMPONENTS

A substrate of an electronic device includes a first set of contact pads and a first set of contact pillars having a height greater than the first set of contact pads. Components are coupled to the first set of contact pads and the first set of contact pillars in traversing directions. The components coupled to the contact pillars are positioned above the components coupled to the first set of contact pads such that at least a first portion of a first side of the component coupled to the contact traces faces a first side of the components coupled to the contact pillars. Stacking passive components in this manner can allow for increased component density without increasing package size.
