Automation of Pulse Electric Strength Test of Electronic Component Base

Resumo

During the pulse electric strength test of the electronic component base (ECB), the single pulsing electrical overstress (EOS) of increasing amplitude affects the tested specimen until a functional or parametric failure of the product appears. In order to reduce the test time and minimize operator intervention, a specialized test bench was designed to perform the test in automatic mode. To have the possibility to switch the specimen between a sensitive measuring instrument and a high-voltage pulse generator, a mechanical switching device was developed, which also operates as a connecting link between test bench components. After putting the test bench into operation, the time of preparation and the test significantly decreases. Furthermore, it became possible to test the electronic component base on the multiple actions of voltage pulses.
