System Design Information
Figure 22. 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:
