Assembling the module on heat sink
9.1
Assembling Easy1B/2B module on heat sink
The module is mounted onto the heat sink using M4 screws. It is also possible to use an additional flat washer.
The heat sink has to be provided with threaded holes as shown in Figure 14.
Figure 14
Spacing of the threaded holes
Note: If the module is first pressed in to the PCB, or if a later disassembling of the module is desired, the PCB
must contain suitable through-holes. The hole size depends on the screwdriver size or the screw’s head
diameter or washer.
The module should be positioned onto the heat sink in such a way that the holes of the screw clamps are
exactly above the threaded holes of the heatsink. The mounting surface must be clean and free of
contamination.
The module can be fastened by screwing in and tightening both screws at the same time (Figure 15a) or by
holding down the module during the mounting process with a force of approximately 10 N so that the module
cannot rise up (Figure 15b).
