Xbee3 micro keepout for test points

0 votes
We have two custom boards where the Xbee3 micro (u.fl version) stopped working after some weeks. The device is not blinking the ASSOCIATE led, does not appear in the zigbee network and does not respond the commands via serial interface (DIN, DOUT).

Rereading the HW reference manual, we saw that we forgot to leave the testpoints area under the device open, so under the device there is a solid ground plane (whithout vias or traces) covered with sodermask.

This situation can lead the device to burn or fail?

Yes that can and will likely cause the module to fail.
