The solder tab is used to melt and weld two superimposed components together after heating. A plurality of inner upward flangings are arranged at the inner diameter of the solder tab, and a plurality of outer downward flangings are arranged at the outer diameter. The inner upward flangings are used for inner and upper side positioning, and the outer downward flangings are used for outer and lower side positioning. When the solder tab is in use, a component one in the shape of a rectangular ring thin sheet and a component two in the shape of a rectangular ring thin sheet are respectively superimposed and placed on the upper and lower sides of the solder tab. The component one, the solder tab and the component two are superimposed together in the order from top to bottom.
