https://devzone.nordicsemi.com/f/nordic-q-a/18802/nrf52-pcb-inconsistent-issuesI have designed a few PCBs using the NRF52 chip with a standard QFN48 pattern. On the first design, we had 8 PCB&#39;s made of which, only 2 worked correctly. The others all exhibited different issues including.

You may want to post your schematic and layout for reviewing.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/72610?ContentTypeID=1Thu, 05 Jan 2017 15:08:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bb67997d-0bd9-446c-898c-264d8fe5a162AmbystomaLabs<p>richard.moldovan@ambystomalabs.com</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/72609?ContentTypeID=1Thu, 05 Jan 2017 15:06:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ce262c28-aa13-4433-8149-df3ac8dfac4flee.W<p>That would be great thank you.
