The current resistance test is to apply a certain DC current on the specially designed hole chain, and for a period of time, the current produces Joule heating on the hole chain, and the heat is transferred to the substrate near the hole chain, and the substrate is heated and expanded to produce Z-direction expansion stress resulting in blind hole breakage, so as to detect the interconnection reliability performance of the hole chain
