Heatspreader
A.1
Description
The heatspreader on top of the ETX-EV133 is not a heatsink !
The heatspreader function is to ensure an identical mechanical profile for every type of ETX
module. In this way the heatsolution, that is built on top of the heatspreader is compatible with
any kind of ETX module not just the ETX-EV133. It enables the second source model for ETX or
upgrade path to a higher performance ETX module. Any change in ETX board type does not
requirre the complete rebuild of the heat solution in your application.
Remove the protective layer
before placing the heatspreader
on the module !
