Integrated heat spreader with mechanical interlock designs

Abstract

An integrated heat spreader is presented. The heat spreader is constructed and arranged to be adhesively affixed, with a sealant, to at least a portion of a component, such as a substrate. The heat spreader includes a body portion, a lip portion substantially vertically oriented and integrally formed with the body portion, and a step portion integrally formed with the lip portion. As such, adhesion of the heat spreader to the sealant is increased, and failure due to shear stresses at the heat spreader bonding surface is prevented.

1 - 17 . (Canceled)  
     
     
         18 . An integrated heat spreader constructed and arranged to be adhesively affixed, with a sealant, to at least a portion of a component, the sealant to act as an adhesive interface between the integrated heat spreader and the component, comprising: 
 a body portion; and    a lip portion vertically oriented relative to the body portion, the lip portion being constructed and arranged to define a channel in a face thereof.    
     
     
         19 . The integrated heat spreader of  claim 18 , wherein the channel is substantially concave.  
     
     
         20 - 23 . (Canceled)  
     
     
         24 . A method of making an integrated heat spreader, comprising: 
 forming a body portion; and    forming a lip portion vertically oriented relative to the body portion, wherein the lip portion defines a channel in a face thereof.    
     
     
         25 . The method of  claim 24 , wherein the channel is substantially concave.
