ANSI C63 16:2016 pdf download.Electrostatic Discharge Test Methodologies and Criteria for Electronic Equipment.
ANSI C63 16 establishes electrostatic discharge (ESD) immunity criteria for electronic equipment
subject to ESD during normal operation and defines test methods for evaluating ESD immunity.
Included are discharges from personnel occurring directly via a small hand held piece of metal
(human/metal ESD) to the equipment and to conductive objects near the equipment.
ESD simulation parameters, test waveforms, and basic test methodologies that are applicable to a wide range of electronic products are defined.
Specific immunity criteria, test methods and test limits based on installation environment or equipment use requirements are given for Information Technology Equipment (ITE), Telecommunication Equipment, and Consumer Products. The general test methods described herein could be applied to other equipment types.
This standard does not include specific performance criteria or test levels for automotive products, military equipment and medical devices. However, the general test methods described herein could be applied to those products. This standard does not cover ESD immunity in manufacturing environments nor equipment used in handling and packaging semiconductor devices. It also does not apply to equipment being serviced and/or repaired.
2. Introduction
ESD occurs when the static electric field between the two objects exceeds the dielectric strength of the air between them. The discharge is a complex event involving a localized transfer of charge at the point of discharge, electromagnetic near field coupling between the objects involved, induced current flow in the object receiving the discharge and radiated electromagnetic energy from the charged object as well as from the arc of the discharge. All of these phenomena are capable of causing malfunctions and, in some cases, damage in electronic equipment.
The electrostatic discharge phenomenon is expected to be a single occurrence in a larger time frame. During this discharge event, electric charge is exchanged between two objects. It is not considered common that within a short time frame (< 10 seconds) multiple single discharges will occur. As such, the ESD test methods defined in this standard are considered as single ESD events. For the sake of testing, the repetition rate of the ESD pulse may be increased up to a level that the EUT is capable to recover (either by hardware or software control) and/or the EUT is capable to discharge prior to the following ESD event. The longest time necessary to recover shall be taken as the maximum repetition rate of the ESD pulses applied. Two discharge modes are used in ESD testing: 1. Air discharge 2.
