At which humidity level should ESD verification be performed?

The appropriate humidity level for performing Electrostatic Discharge (ESD) verification is critical for ensuring the safety and reliability of electronic assemblies. ESD verification should be conducted when humidity levels are below 30%. At this humidity level, the risk of ESD events is significantly heightened because low humidity can lead to the accumulation of static charges on surfaces. When the humidity is low, surfaces do not effectively dissipate static charges, making it more likely for static electricity to discharge and cause damage to sensitive electronic components.

This standard emphasizes maintaining control over environmental conditions to protect electronic assemblies from the potentially damaging effects of ESD. Conducting ESD verification below 30% ensures that appropriate measures can be taken to mitigate the risks associated with high ESD potential.
