Product Number: ADALM-PLUTOSDR
I have a two ADALM-Pluto units, RevD, that I purchased a few years ago. Normally I keep the boards in their plastic cases, but recently when I opened a case I could see what appears to be heavy oxidation or tarnish on the tracks that connect the SMA connectors to the balun transformer. I suppose this is sulfur reacting with immersion silver surface plating.
My question is whether this tarnish will cause any performance or reliability issues down the road? I tried a couple hours of internet research but could not find a definitive answer.
