| Abstract: | The soldering quality of the surface mounting rectifier diode has direct effect upon its reliability.A new method was proposed for estimating the soldering quality through the test of thermo-sensitive voltage increment which equals the transient thermal resistance,thus screening the deficient soldering product.The sample online screening in appropriate condition using TRR8000 tester rejects the deficient soldering product efficiently and enhances the reliability of the surface mounting rectifying diode. |
