Abstract
The utility model discloses a fixable circuit board which comprises a circuit board main body, a triode and an aluminum alloy loading plate used for being connected with a matched use device. The triode is fixed on the circuit board main body and is electrically connected with the circuit board main body. The aluminum alloy loading plate is further fixedly connected onto the back face of the triode. Due to the fact that the aluminum alloy loading plate is arranged on the fixable circuit board to serve as the loading plate of the circuit board body, great heat dissipated instantaneously when huge current or voltage passes through the circuit board body can be quickly dissipated to the surrounding environment, board burning caused by high temperature and high voltage is avoided, and the circuit board is suitable for being used under high voltage or large current. Simultaneously, the circuit board body is fixed on the aluminum alloy loading plate in element mode, weight born by the circuit board body is greatly reduced, and board twisting caused by the fact that load on the circuit board body is too large is prevented.
