Abstract:
A method for increasing electronic component density on an electronic circuit board, the electronic circuit board having an electrically conductive signal layer formed on a dielectric layer, the electrically conductive signal layer having a plurality of electrically conductive pads formed therein, the method comprising the step of:forming a cavity in the electronic circuit board extending through the electrically conductive signal layer and the dielectric layer, wherein the cavity is sized to accommodate a first electronic component therein such that at least one first electrical connection may be formed between the first electronic component and a first portion of the plurality of electrically conductive pads, and at least one second electrical connection may be formed between a second electronic component, which is stacked over the first electronic component, and a second portion of the plurality of electrically conductive pads.
