System Design Information
the selection of any thermal interface material depends on many factors—thermal performance
requirements, manufacturability, service temperature, dielectric properties, cost, and so on.
Figure 23. 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 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:
