    Default Fixing a cracked circuit board

    I have an older Pioneer tuner which appears to work, except there is a crack in the circuit board just before the Left and Right outputs (on the actual output circuits that carry the signal to the output RCA plugs).

    I would like to fix this for use as my garage tuner....any suggestions? thanks......

    Hi,
    If the crack is to the board itself and the conductive trace is intact then you can use a good quality two-part epoxy to repair the break, holding the pieces together while the glue sets up. If the signal traces have broken then use small bits of insulated wire to complete the connection on either side of the break after the crack has been repaired.

    Good advice. If the trace is too difficult to solder wires on to, there is electrically conductive paint available. I had used this on a board that I had etched and needed to add a trace. They may even have it in marker form.

    Depending on the size of the trace, you can also solder over the break. Once the glue or epoxy has set fully, you can clean the trace of any conformal coating or oxidation. Using a good quality solder like Cardas Quad Eutectic, you can flow a bead right over the break
