A circuit board structure of a rectifier bridge of an alternating current generator for a Mitsubishi automobile. The circuit board structure includes a PPS substrate, a plurality of pre-embedded sheets are arranged on the PPS substrate, I-shaped windows are arranged on the pre-embedded sheets used for assembling positive and negative electrode diodes, heat dissipation openings are arranged on the pre-embedded sheets used for assembling the positive and negative electrode diodes, and the circuit board structure is characterized in that the PPS substrate is provided with grooves at upper sides of the pre-embedded sheets used for assembling the positive and negative electrode diodes, and lower sides of the grooves are open and are adjacent to the pre-embedded sheets used for assembling the positive and negative electrode diodes. The circuit board structure of the rectifier bridge of the alternating current generator for the Mitsubishi automobile has the beneficial effects that the circuit board structure is improved, a long strip-shaped through ports on an original circuit board is cancelled, the grooves are additionally arranged on the upper sides of and next to the pre-embedded sheets used for assembling the positive and negative electrode diodes, and in welding, soldering tin flows into the grooves, so as to be prevented from directly flowing to the generator when stator leads are welded to the positive and negative electrode diodes assembled on the circuit board, thereby improving quality of a product, and satisfying requirements of a customer.
