Abstract The hipot test, short for “high potential” test, is crucial for assessing the dielectric strength of electrical components, especially capacitors. It verifies that these components can withstand high voltages without breaking down or leaking excessive current. The key parameter in this test is the hipot test acceptable leakage current, which defines the limit of current that c...
Abstract Electrostatic discharge (ESD) is a critical concern in semiconductor device manufacturing and testing, as it can cause significant damage to integrated circuits (ICs). Among the various ESD models used for testing, the Human Body Model (HBM) is the most prevalent for simulating electrostatic discharges that mimic human contact with sensitive devices. This paper explores the ESD HBM model ...
