The board designer can choose between several types of heat sinks to place on the 750. There are several  
commercially-available heat sinks for the 750 provided by the following vendors:  
Chip Coolers, Inc.  
333 Strawberry Field Rd.  
Warwick, RI 02887-6979  
800-227-0254 (USA/Canada)  
401-739-7600  
Thermalloy  
214-243-4321  
2021 W. Valley View Lane  
P.O. Box 810839  
Dallas, TX 75731  
International Electronic Research Corporation (IERC) 818-842-7277  
135 W. Magnolia Blvd.  
Burbank, CA 91502  
Aavid Engineering  
One Kool Path  
Laconic, NH 03247-0440  
603-528-3400  
617-245-5900  
Wakefield Engineering  
60 Audubon Rd.  
Wakefield, MA 01880  
Ultimately, the final selection of an appropriate heat sink for the 750 depends on many factors, such as ther-  
mal performance at a given air velocity, spatial volume, mass, attachment method, assembly, and cost.  
Internal Package Conduction Resistance  
For the exposed-die packaging technology, shown in Table “Package Thermal Characteristics1,” on page 8,  
the intrinsic conduction thermal resistance paths are as follows.  
• Die junction-to-case thermal resistance  
• Die junction-to-ball thermal resistance  
Figure 21 depicts the primary heat transfer path for a package with an attached heat sink mounted to a  
printed-circuit board.
