The utility model particularly relates to an assembly method of a silicon rectifier bridge for an automotive generator and applied automotive rectifier diodes with a single-side semi-spherical copper electrode. The electrode on one side of each diode has semi-spherical copper particles, and the electrode on the other side has flat copper particles. The flat electrode is connected with cooling fins, and the semi-spherical copper particles are connected with a semi-spherical concave conductive sheet. The conductive sheet is embedded in an insulation bracket by injection molding, and is made of a copper plate with good elasticity by stamping with certain interference, so that the radial pressure offset can be corrected automatically to ensure the pressure to be uniformly distributed on the cooling fins, thereby achieving uniform force on the six rectifiers, and enhancing the reliability of the rectifier bridge.
