Abstract

A circuit for recording a magnitude of an ESD event during semiconductor assembly includes a voltage divider connected between an input and a ground. The circuit also includes a measurement block having a recorder device. Each measurement block receives current from a segment of the voltage divider. The magnitude of the ESD event is determined based upon a read-out of the measurement devices after the ESD event. The recorder device may be a capacitor that would be damaged during the ESD event. During the ESD event the capacitor may be damaged. Reading out the recorder device determines if the magnitude of the ESD event exceeded a threshold magnitude that damages the capacitor.
