The electronics industry especially LEDs has recognized the significance of Electrostatic Discharge (ESD) as a potential source of damage and recognized as a significant contributor of failures throughout the operating life of a semi-conductor device. Although present integrated circuit designs include ESD protection circuitry, the effectiveness of this protection must be determined in a manner which will ensure its effectiveness in the “real world” if the part is to meet the reliability requirements of the application.
ESD has been studied for some time, and there is reasonable agreement on three (3) models for this phenomena: The Human Body Model (HBM), Machine Model (MM), and Charged Device Model (CDM). In this article, we will be focusing on the HBM and some concerns we have about the model as presently defined. Under various conditions, the human body can be charged with electrical energy and transfer that charge to a semiconductor device through normal handling or assembly operations, the problem is we will not determine the damage we caused to these semi-conductors. In order to protect the life of LEDs and Integrated Circuit (IC), here at Enimex the home of Yosbo lighting solutions, we implement ESD protection campaign, from our cotton uniform to the lab gown in production and we even have our ESD shoes to promote a “no dust factory” and continue providing our clients a quality LED lighting system by eliminating the amount of ESD that we transfer to the LEDs and IC.
