Assembly Instructions for the Easy-PressFIT Modules
In Figure 26a, the Easy3B module(s) is pressed into the PCB.
Figure 26b shows the process where the PCB with the pre-assembled modules is placed on the cooling system,
and the modules are fixed with screws. Please refer to Chapter 9.2 for detailed information on assembly of the
Easy3B modules on the heat sink. It is important to mount the modules before the PCB is fixed to the cooler!
Figure 26c shows the fixing of the PCB to the heatsink. As the height tolerance of the module is quasi
compensated in the press process, the fixing points for the PCB can be close to the power modules. This is an
advantage compared to the concept in Section 10.1 where >=5 cm distances have to be maintained between
module and distance keepers.
The position of the distance keepers should be designed symmetrically around the power module(s).
Figure 26d shows the final system assembly.
