We got a perculiar problem with a FXO8700 or FXAS21002 sensor both placed on the same PCB.

Our product works fine but stops working the moment the lit of our product is placed onto the bottom of the device.

We established that the click of the spring action lit upsets one or both of the sensors. The strength of the click is like a ball point click. The moment the PCB with those sensors is exposed to such click the data coming out of the sensors is completely corrupted and stays corrupted.

We are sure it is the little click because if we bend the spring so that no hard click is made the sensors keep on working fine.

Is the phenomenon known to other users of the community ?

 

Could the G force spike of such a click upset the registers inside the sensors somehow ?

Under all other conditions both sensors work perfect without a glitch.

Ruud
