Abstract
A post in ring interconnect used for 3-D stacking. A retaining ring is formed on a pad on a bottom surface of a top PCB substrate to be stacked with a bottom PCB substrate. A post is formed on a pad on a top surface of the bottom PCB substrate. A conductive paste is applied on the pad on the bottom surface of the top PCB substrate and retained in a pocket partially defined by the retaining ring. The retaining ring is aligned with the post. By performing a compression step, a eutectic bond is formed between the top and bottom PCB substrates by the post and the conductive paste.
