1.2.1 Mechanical Specification

Following figure shows the mechanical drawing of SOM-A2552 series.

The above figure shows the SOM-A2552 mechanical drawing. Users could follow the above figure to implement the layout procedure.

1st drawing shows the SOM-A2552 module PCB mechanical data. When users enter the layout procedure, user could follow the 1st drawing to place the connector. SOM-A2552 series PCB form factor is 68mm*68mm*68mm.

The 2nd drawing shows the PCB thickness limitation. The component side height is 2.8mm, and the solder side maximum height is 3.00mm and the PCB thickness is 1.00mm.

The 3rd drawing shows allied mechanical data of SOM-A2552 series board and CSB. Users could see that the matting height is 3.00mm and the solder side maximum height of SOM-A2552 is also 3.00mm. So, Advantech don’t suggest users to place any components between SOM module and CSB in layout stage. It could be short!
