System Design Information

Figure 27 describes the thermal performance of select thermal interface materials.

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:
