vias descoloration | 23 February, 2021


I have a topic with vias discoloration(that's what supplier said) and I don't know if it's an corrosion problem or something else. I believe that maybe the PCB's are not storage properly. I must mention that aren't any problem at soldering. Did anybody seen this before?
