IEC 61340-5-1:2024

Overview

IEC 61340-5-1:2024 - Electrostatics: Part 5-1 - defines general requirements for protection of electronic devices from electrostatic phenomena. It specifies the administrative and technical elements needed to establish, implement, and maintain an ESD control program for organizations that manufacture, process, assemble, install, package, label, service, test, inspect, transport or otherwise handle electrical/electronic parts and equipment. The standard targets items with ESD withstand voltages ≥ 100 V (HBM) and 200 V (CDM), and addresses isolated conductors by limiting voltage to < 35 V.

Key Topics and Requirements

• Scope & exclusions: Applies to typical electronic manufacturing and handling activities; excludes electrically initiated explosive devices and volatile flammables (liquids, gases, powders).
• ESD control program: Administrative and technical program requirements including program plan, training, product qualification plan, and compliance verification plan.
• Personnel safety: Requirements and considerations for safe implementation of ESD control measures.
• Grounding / equipotential bonding: Rules for grounding systems and bonding to create equipotential environments that prevent discharge to ESD sensitive devices (ESDS).
• Personnel grounding: Requirements for wrist straps, footwear, and groundable garment systems (note: the 2024 edition adds reference to groundable static control garment systems).
• ESD Protected Areas (EPA): Definition, control zone elements, and technical items for establishing EPAs; updated Table 3 in this edition lists EPA technical requirements.
• Insulators and isolated conductors: Updated definitions and process controls for insulating materials and isolated conductors.
• Packaging and marking: Requirements for static-protective packaging and labeling, summarized in new Table 4; includes compliance verification for packaging.
• Product qualification & testing: Updated product qualification requirements; compliance verification references IEC 61340-5-4 for testing methods.
• Tailoring: Examples and guidance on tailoring an ESD program to specific processes (Annex A replaced with tailoring examples).

Practical Applications and Who Uses It

IEC 61340-5-1:2024 is used by:

• Electronic manufacturers and contract manufacturers (PCBs, semiconductors, modules)
• Test, inspection and repair facilities
• Packaging and logistics organizations handling ESDS
• Quality, EHS and process engineers implementing ESD controls
• Suppliers who must qualify products or packaging for ESD-sensitive supply chains

Benefits include reduced ESD-induced failures, consistent compliance verification, and clearer contractual and process requirements across global supply chains.
