The ordinate cutting,which means that the laser-trimming path is parallel to the current flow,increases the resistance slowly.
激光调阻中激光束平行于电流方向的纵向切割对片式电阻的阻值变化影响较小,掌握其规律并将其应用于调阻过程中能够为提高激光调阻精度提供控制依据。
The laser-trimming path that is parallel to the current flow, called ordinate cutting, increases the resistance slowly.
激光在片式电阻上的纵向切割对阻值变化影响较小 ,合理设计其长度可以提高激光调阻精度及保证阻值稳定性。
