System Design Information

of any thermal interface material depends on many factors—thermal performance requirements,

manufacturability, service temperature, dielectric properties, cost, and so on.

Figure 25. Thermal Performance of Select Thermal Interface Material

The board designer can choose between several types of thermal interfaces. Heat sink adhesive materials

should be selected based on high conductivity and mechanical strength to meet equipment shock/vibration

requirements. There are several commercially available thermal interfaces and adhesive materials

provided by the following vendors:
