System Design Information
Figure 27. Thermal Performance of Select Thermal Interface Materials
The board designer can choose between several types of thermal interface. Heat sink adhesive materials
should be selected based on 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:
