Questions about hardware.
What is the thermal resistance of the nRF52832 WLCSP?
Any information on θJC (° C / W or K / W)?

Thank you for your answer.

Finally, let me ask you one question.

Is there any possibility that it will exceed 600k / W with nRF52832?

Hi!

Unfortunately, I'm not sure. We are short on staff due to the holidays here in Norway, so I'll have an answer for you at the beginning of week two. 

Best regards,

Thank you for contacting us.
I'm sorry, confirmation was delayed because I was on vacation.

I understand that it takes time to answer,
Looking forward to the answer at the beginning of the second week.

Best regards,

Hi again!

The normal value is 40 k/W case to ambient for QFN. It is possible that the value is higher for WLCSP but no, it's not possible that it will exceed 600 k / W.
