Mounting of COM-C Modules
The COM-C Module has two metal blocks for mounting. This guaranties a robust mechanical con-
struction and a solid connection to earth ground for the fieldbus connector. The metal blocks define
also the distance between the Module and host board. They are connected together with M2.5
screws.
On the front side of the metal blocks there are a M2.5 thread to mount a front panel directly on the
Module. This allows to have the same cutting in the device housing for all types of Modules.
Use fine technology that means six-mil-wide (150
μ
m) tracks
Note
With this you have the possibility to get out between the pads.
For the power tracks you can insert a via straight in the pad.
To prevent a soldering problem please use a fine via (drill 0,2 mm).
Place a via between board edge and connector pad
Note
There is 1 mm space between the connector and the board edge, where you can place
a
'normal' via (drill 0,3 mm) to feed the signals to the bottom side.
