Surface Mount Components Joined Between a Package Substrate and a Printed Circuit Board

摘要

A microelectronic package and a method of forming the package. The package includes a first level package mounted to a carrier. The first level package includes a package substrate having a die side and a carrier side; and a microelectronic die mounted on the package substrate at the die side thereof. The carrier has a substrate side, and the first level package is mounted on the carrier at the substrate side thereof. A rigid body is attached to the carrier side of the substrate at an attachment location of the substrate and to the substrate side of the carrier at an attachment location of the carrier, the attachment location of the carrier being electrically unconnected, the rigid body being configured and disposed to provide structural support between the substrate and the carrier.
