Abstract

An electronic testing machine includes a plurality of test modules. Each test module has a plurality of contact pairs for testing electronic components. An apparatus and process for electrical test setup and calibration of the electronic testing machine includes a plate having at least one contact per track movable between test positions to electrically insert a test device selectively between any one contact pair, and a control program. The test device can be selected from a group consisting of a volt meter, a current meter, a precision voltage/current source, a calibration resistor, and a calibration capacitor. The control program can perform at least one test function through the plate. The test function can be selected from a group consisting of alignment verification, voltage/current source verification, insulation resistance (IR) leakage measurement verification, part-present contact check verification, capacitance and dissipation (CD) measurement verification, IR/CD compensation, and IR/CD calibration.
