Method and system for thermomechanically decoupling heatsink

Abstract

A method of mounting a heat sink includes providing a heat sink having a plurality of mounting points, and attaching a plurality of mounting members to the heat sink at the plurality of mounting points, respectively, at least one of a combination of a mounting point of the mounting points and a mounting member of the mounting members being configured so as to have a stiffness in a thermally-induced expansion direction of the heat sink at the respective mounting point which is less than a stiffness in an other direction at the respective mounting point.

What is claimed is: 
     
         1 . A method of mounting a heat sink, the method comprising:
 providing a heat sink having a plurality of mounting points; and   attaching a plurality of mounting members to the heat sink at the plurality of mounting points, respectively, at least one of a combination of a mounting point of the mounting points and a mounting member of the mounting members being configured so as to have a stiffness in a thermally-induced expansion direction of the heat sink at the respective mounting point which is less than a stiffness in an other direction at the respective mounting point.   
     
     
         2 . The method according to  claim 1 , wherein the attaching of the plurality of mounting members includes attaching at least an other combination of a mounting point of the mounting points and a mounting member of the mounting members so as to form a no-slip connection. 
     
     
         3 . The method according to  claim 1 , wherein the plurality of mounting members have a soft bending axis, and
 wherein the attaching of the plurality of mounting members further includes orienting the soft bending axis of the plurality of mounting members such that the soft bending axis is perpendicular to the thermally-induced expansion direction at the plurality of mounting points.
