AD7147 Wiring to Evaluation Board

Hi,

 

I'm wondering if anyone can look at this PCB I've designed and let me know if it looks right or needs to be changed. This is to connect an external AD7147 to the evaluation board through its external connector. The PCB is designed to measure force. Each pad on the PCB is covered in a layer of silicon, then a piece of aluminum is placed on top. Applying force to the aluminum should squish the silicon and change the distance between the aluminum and pad on the pcb, thereby changing resistance.

 

The choice to use CIN 0 and CIN 2 was just to make soldering easier.

 

Thanks,

Dave
