| description | The invention provides an SC-cut crystal oscillator for inhibiting B-mode oscillation and a manufacturing method. The SC-cut crystal oscillator for inhibiting B-mode oscillation comprises an SC-cut crystal, an upper electrode is arranged on the upper surface of the SC-cut crystal, and a lower electrode is arranged on the lower surface of the SC-cut crystal; the upper electrode and the lower electrode are metal sheets which are symmetrically arranged on the upper surface and the lower surface of the SC cut-type crystal and have the same shape, a displacement current vector direction is taken as a reference, one metal sheet on the upper surface of the SC cut-type crystal is cut off from the left side, and one metal sheet on the lower surface of the SC cut-type crystal is cut off from the right side. The method comprises the steps of SC crystal cutting, electroplating film adding, trimming and the like. According to displacement current vector directions of a B mode and a C mode during oscillation of the SC cut |
