  • Patent number: 4578637
    Abstract: A device for testing continuity and current leakage at leads of an electronic circuit such as an integrated circuit has a contact structure (16) having test terminals (T1-T28) for contacting the leads. A first and a second of the leads are power supply leads respectively contactable with a first and a second of the test terminals (T14 and T28 or T26). Continuity/leakage detection is done with one or more corresponding detection circuits (D1-D28). Each detection circuit has a channel along which both continuity and leakage are tested. A supply switching circuit (26) appropriately switches voltages between values suitable for continuity testing and values suitable for leakage testing.
