Embodiments of the present invention are directed to an integrated circuit (IC) package assembly. The IC package assembly includes a base printed circuit board (PCB), and a set of IC packages. Each of the IC packages includes at least one IC chip, mounted on or partly in a support component, which mechanically supports and electrically connects to the IC chip. In addition, each of the IC packages is laterally soldered to the base PCB (e.g., a motherboard PCB) and arranged transversally to the base PCB and forms an angle &#x3b1; therewith. As a result, a slanted stack of IC packages is obtained, wherein the IC packages are essentially parallel to each other. Further embodiments are directed to related devices, including the above assembly, and to related fabrication methods.

Integrated circuit package assembly comprising a stack of slanted integrated circuit packages

A printed circuit board (PCB) assembly includes a first PCB and a second PCB disposed substantially parallel and opposite to each other, such that a second side of the first PCB is opposite to a first side of the second PCB; wherein the second PCB has a first set of side connectors on its first side and a second set of side connectors on its second side, configured for both electrical power supply to and signal communication with the second PCB; the second PCB both electrically and mechanically connected to the second side of the first PCB via a first elastomeric connector; and the second PCB electrically connected to the first PCB via its second set of side connectors and a flexible electrical connector that is electrically connected to the second set of side connectors and the first PCB.
