Abstract:
A stacked via structure for reducing vertical stiffness includes: a plurality of stacked vias, each via disposed on a disc-like structure. The disc-like structure includes a plated through hole landing supporting the plurality of stacked vias. The plated through hole landing includes a compliant center zone; and spring-like stiffness-reducing connectors for connecting the compliant center zone of the plated through hole landing.
Abstract:
A substrate via structure for stacked vias includes: a plurality of stacked vias, wherein each via is disposed on a landing; and at least one constrainer disc surrounding at least one via, for constraining in-plane deformation of the substrate via structure. The constrainer disc is embedded such that the constrainer disc is disposed between two layers of resin. The constrainer discs may be made of copper. The constrainer disc may be circular or square-shaped. Preferably there is a dielectric gap between the constrainer disc and the via.
