AWR1243BOOST: about the oxidation of the immersion silver finish of the PCB

Zhicheng Hu

Part Number: AWR1243BOOST

I have tested the AWR1243BOOST in the open environment for 4 weeks. Has the immersion silver finish of the PCB been oxidized? Dose it matter?

What influence will it make?

Thank you!

Hello,
This should not be an issue.

Are you seeing any issue / performance degradation on your EVM ?

Hello Zhicheng,
If the PCB is kept out and exposed to air for long periods the immersion silver does tend to get oxidized. What we have learnt from some analyzes done by material vendors is that over years also this oxidation does not impact the RF performance. But we recommend proper storage of the PCB to reduce the oxidation.

Vivek
