IEC 61340-5-1:2016

Overview

IEC 61340-5-1:2016 - “Electrostatics - Part 5-1: Protection of electronic devices from electrostatic phenomena - General requirements” defines the administrative and technical requirements for establishing, implementing and maintaining an ESD control program. The standard applies to activities that manufacture, process, assemble, install, package, label, service, test, inspect, transport or otherwise handle electrical/electronic parts, assemblies and equipment with typical withstand thresholds of ≥ 100 V (HBM), ≥ 200 V (CDM) and ≥ 35 V for isolated conductors. It excludes electrically-initiated explosives and flammable liquids/gases/powders. IEC TR 61340-5-2 gives implementation guidance; Annex A contains normative test methods. This edition incorporates technical alignment with other industry ESD standards, adds product qualification, and defers detailed packaging requirements to IEC 61340-5-3.

Key topics and technical requirements

• ESD control program: required plan documenting scope, responsibilities, tailoring and technical controls. An ESD coordinator role is recommended.
• Administrative elements: ESD control program plan, ongoing training plan, product qualification requirements, and a compliance verification plan (audits and testing).
• Grounding and equipotential bonding: requirements for grounding systems to prevent potential differences between personnel, equipment and conductors.
• Personnel grounding: wrist straps, footwear and other measures to control charge on personnel inside ESD Protected Areas (EPAs).
• ESD Protected Areas (EPA): zoning, material selection and controls to maintain equipotential balance inside work areas.
• Packaging and marking: general packaging/marking requirements are covered; detailed packaging specifications are in IEC 61340-5-3.
• Test methods: Annex A lists test procedures for verifying grounding, wrist straps, footwear and other controls.
• Tailoring and risk: devices with lower ESD withstand voltages may need additional controls or adjusted limits; processes handling such devices can still comply if controls are documented.

Practical applications - who uses it and why

• Target users: electronics manufacturers, PCB assemblers, test labs, packaging/transport teams, service and repair centers, design and quality engineers, and supply chain managers.
• Use cases:
  • Establishing company-wide ESD control programs and training curricula.
  • Designing EPAs, grounding/equipotential systems and personnel grounding methods.
  • Defining product qualification and compliance-verification procedures for HBM/CDM sensitivity.
  • Specifying packaging and handling requirements for shipment outside EPAs.
  • Integrating ESD controls into quality management and supplier requirements.
