1990s SMD electrolytic capacitorps. #Nintendo #SNES

Closeup of the circuit board from the SNES I’m working on. Some of the SMD capacitors have clearly leaked and corroded the traces around them.

    @janbeta Nintendo motherboards are nice. Always seemed so simple in design.

    Apparently, C59 which has the worst leakage is supposed to be a bipolar cap. Nintendo corrected it in the next board revision. 🤦 #Nintendo #SNES

    @janbeta wait.. it is supposed to be, does that mean it isn't and gets reverse voltage across it sometimes??
