  • Piezo ceramic turning brown!

    I've just been tidying up my kit a bit and discovered that nearly all of the piezos have browned, its more obvious near the connections.
    I didn't solder these myself so its not that.

    Anybody know i this is normal or seen it before?

    Thanks

    After I peel them, I like to put my piezos in some cold water...this prevents browning.

    What a minute...that's what I do with potatoes

    I don't know why they brown but I have one I use as a template and the ceramic on it has discolored...I doubt it will affect performance.

      The flux splatter can be corrosive, some more than others I think. It may be good practice to clean it up after soldering. I used rubbing alcohol and a q tip. I think there are products out there to neutralize the worst of the flux types.

      The piezos on my Rolands are all discolored and they trigger great still.
