Introduction

As electronic components become smaller and more sensitive, electrostatic discharge (ESD) has become a major cause of hidden product failure. IEC 61340-5-1 provides a globally recognized framework to control this risk.

This article explains what IEC 61340-5-1 is and why it matters for electronics manufacturing.

Understanding Electrostatic Discharge

ESD occurs when static electricity transfers between objects at different electrical potentials. Even discharges below human perception can damage:

• Integrated circuits

• PCBs

• Microprocessors

What Does IEC 61340-5-1 Cover?

IEC 61340-5-1 defines requirements for:

• Personnel grounding

• ESD workstations

• Flooring and footwear

• Packaging

• ESD garments

The goal is to create a complete ESD control system.

Why IEC 61340-5-1 Is Important

1. Product Reliability

ESD damage often causes latent failures—products fail weeks or months later. Compliance reduces warranty claims and recalls.

2. Global Recognition

IEC 61340-5-1 is widely accepted across:

• Europe

• Asia

• Global electronics supply chains

It simplifies supplier qualification.

3. Audit & Customer Requirements

Many OEMs and EMS providers require IEC 61340-5-1 compliance as part of supplier audits.

Role of ESD Garments

ESD garments reduce charge generation caused by body movement and friction. Without compliant clothing, even grounded personnel can generate harmful static charges.

Conclusion

IEC 61340-5-1 is not just a guideline—it is a critical quality standard. Proper ESD garments are a fundamental part of compliance.
