ETX®-CD / Specification
3.10 Thermal Management
A heatspreader plate assembly is available from Kontron Europe GmbH for the ETX®-CD. The heatspreader plate on top of
this assembly is NOT a heat sink. It works as a ETX®-standard thermal interface to use with a heat sink or other cooling
device.
External cooling must be provided to maintain the heatspreader plate at proper operating temperatures. Under worst-
case conditions, the cooling mechanism must maintain an ambient air and heatspreader plate temperature of 60° C or
less.
The aluminum slugs and thermal pads on the underside of the heatspreader assembly implement thermal interfaces
between the heatspreader plate and the major heat-generating components on the ETX®-CD. About 80 percent of the
power dissipated within the module is conducted to the heatspreader plate and can be removed by the cooling solution.
You can use many thermal-management solutions with the heatspreader plates, including active and passive approaches.
The optimum cooling solution varies, depending on the ETX® application and environmental conditions. Please see the
ETX® Design Guide for further information on thermal management.
