Electrostatics - Part 5-3: Protection of electronic devices from electrostatic phenomena - Properties and requirements classification for packaging intended for electrostatic discharge sensitive devices
IEC 61340-5-3:2015 defines the ESD protective packaging properties needed to protect electrostatic discharge sensitive devices (ESDS) through all phases of production, rework/maintenance, transport and storage. Test methods are referenced to evaluate packaging and packaging materials for these product and material properties. Performance limits are provided. This standard does not address protection from electromagnetic interference (EMI), electromagnetic pulsing (EMP) or protection of volatile materials. This edition includes the following significant technical changes with respect to the previous edition: a) removal of all references to ANSI/ESD STM11.13, replaced by normative reference IEC 61340-4-10; b) additional notes added to Table 1; c) addition of a new Table 3 related to the "ESD classification symbol" and the "primary function code".
IEC 61340-5-3:2015 is an international standard published by the International Electrotechnical Commission (IEC) that addresses the protection of electrostatic discharge sensitive (ESDS) electronic devices through effective packaging. The standard specifies the essential properties and requirements for packaging materials designed to safeguard such devices from electrostatic discharge (ESD) throughout all phases-production, rework, transport, and storage.
This second edition replaces the 2010 version, introducing key technical updates such as replacing ANSI/ESD STM11.13 references with IEC 61340-4-10, enhancing classification tables for packaging, and introducing an ESD classification symbol system with primary function codes. Importantly, the standard focuses exclusively on electrostatic phenomena, excluding electromagnetic interference (EMI), electromagnetic pulsing (EMP), or protection of volatile substances.
ESD Protective Packaging Properties
IEC 61340-5-3 defines material characteristics such as resistance (conductive, dissipative, insulating) and electrostatic shielding properties necessary to prevent electrostatic discharge damage.
Classification and Marking
The standard provides a clear classification system for packaging based on material properties and functionality, including mandatory markings that denote the ESD classification symbol and primary function code. This supports traceability and easier identification during handling.
Test Methods and Performance Limits
Referenced test procedures evaluate packaging materials against standardized requirements, ensuring consistent protection across different manufacturing and logistics environments.
Tailoring for Environment and Device Sensitivity
Guidance is offered to tailor packaging requirements according to the specific environmental conditions and the sensitivity of the electronic devices, ensuring appropriate levels of ESD protection.
Scope of Protection
The standard applies to packaging used inside and outside electrostatic protected areas (EPA), addressing the entire supply chain from material receipt to end-use.
IEC 61340-5-3 is critical for industries involved in the manufacture, handling, and transportation of electronic components and devices that are sensitive to electrostatic discharge. Practical applications include:
Упомянутые в описании и другие стандарты IEC
Manufacturing: Packaging materials compliant with IEC 61340-5-3 prevent ESD damage during device assembly and testing within a production environment.
Rework and Maintenance: Protective packaging assists in safe handling during servicing or refurbishing electronic modules, reducing risk of discharge damage.
Logistics and Storage: Shipping and storage of ESDS devices require packaging that adheres to the standard’s classification to maintain device integrity through transit and warehousing.
Quality Assurance: The standard’s traceability and marking systems facilitate quality control inspections, ensuring that appropriate protective packaging is consistently used.
Utilizing IEC 61340-5-3 compliant packaging effectively mitigates risks associated with static electricity, thereby enhancing product reliability and reducing costs due to ESD-related failures.
IEC 61340-5-3:2015 is part of the broader IEC 61340 series on electrostatics protection, which includes:
