Abstract
An electronic circuit in which a heat pipe is mounted on a substrate for transporting heat from one region to another, the heat pipe also being secured to the substrate at a plurality of positions along the heat pipe for the purpose of increasing the stiffness of the substrate. The heat pipe may extend across a surface of the substrate or around an edge of the substrate. Heat conductive paths from the heat source may be provided by a ground plane within the substrate or a heat conductor may extend from the heat source to the heat pipe at a position spaced from the substrate.
