MPC7450 RISC Microprocessor Hardware Specifications
System Design Information
selection of any thermal interface material depends on many factors—thermal performance requirements,
manufacturability, service temperature, dielectric properties, cost, etc.
Figure 29. Thermal Performance of Select Thermal Interface Material
The board designer can choose between several types of thermal interface. Heat sink adhesive materials
should be selected based upon high conductivity, yet adequate mechanical strength to meet equipment
shock/vibration requirements. There are several commercially available thermal interfaces and adhesive
materials provided by the following vendors:
