发明名称 Ball grid array package enhanced with a thermal and electrical connector
摘要 Electrically, mechanically, and thermally enhanced ball grid array (BGA) packages are described. A substrate has a surface, wherein the surface has an opening therein. A stiffener has a surface coupled to the surface of the substrate. An area of the surface of the stiffener can be greater than, equal to, or less than an area of the surface of the substrate. A thermal connector is coupled to the surface of the stiffener through the opening. A surface of the thermal connector is capable of attachment to a printed circuit board (PCB) when the BGA package is mounted to the PCB. The thermal connector can have a height such that the thermal connector extends into a cavity formed in a surface of the PCB when the BGA package is mounted to the PCB. Alternatively, the stiffener and thermal connector may be combined into a single piece stiffener, wherein the stiffener has a protruding portion. The protruding portion extends through the opening when the stiffener is coupled to the substrate, and is capable of attachment to the PCB.
