Hi,
We found a very strange problem when designing a product using nrf5340:
The equipment is coated with a layer of UV tri-proof paint on the chip of nRF5340 and the peripheral equipment. At the beginning, the current of the normal temperature test equipment is normal. However, when the equipment is tested at high temperature and high humidity in the high and low temperature box, we find that the current of the equipment is two or three times larger than that of the equipment. The equipment that does not play UV three anti paint looks good.
I would like to ask whether nRF5340 and UV tri-proof paint used together may cause such problems? Is there a three-yard way to circumvent it?
