Ground resistance measurement with Smart Ohm
In battling ESD, factories are equipped with conductive flooring materials to conduct the electric charges from the work area. Operators handling ICs are required to wear special coats with conductive filaments, and/or heel-straps. At the work bench, operators are required to wear wrist straps to ensure that they are grounded. However, based on investigations by ESD experts, less than 0.10% of all the documented damage actually comes from ungrounded personnel touching ESD-sensitive products. In other words, 99.9% of ESD damage is attributed to charging/discharging events that occur in production equipment and processes. Consequently, maintaining ground integrity for equipment plays a vital role in the reduction of ESD.
This application note shows how you can get an accurate ground resistance measurement in the presence of offset voltage using the Agilent Technologies U1272A handheld digital multi-meter with Smart Ohm.
