The control of electrostatic discharge (ESD) in electronic component manufacturing plants mainly follows the international standards after:

• ANSI/ESD S20.20: This is the most widely recognized and popular standard globally, especially in North America and Asia. This standard provides administrative and technical requirements for establishing, implementing and maintaining an ESD control program to protect sensitive electronic components.
• IEC 61340-5-1: This international standard (IEC) has similar content and objectives to ANSI/ESD S20.20, and is often adopted as a national standard in many countries, especially in Europe.

Measuring body static electricity (or electrostatic discharge – ESD) control in electronics manufacturing is extremely important Because electronic components, especially microchips and semiconductors, are very sensitive and easily damaged by small currents caused by static electricity. 

The main reasons include:

• Prevent component damage: The human body can build up electrical charges without even realizing it (for example, just walking on some surfaces can generate several thousand volts). When touching a sensitive electronic component, this discharge (spark), while not shocking the person, is powerful enough to damage the internal structure of the component.

• Avoid potential errors: Damage caused by ESD may not be immediately apparent (latent failure), but will reduce the product's lifespan and reliability, resulting in product failure after a period of use in the hands of customers.

• Product quality assurance: Static control helps maintain product quality and stability, reduce the rate of defective products (scraps), thereby saving production and warranty costs.

• Compliance with standards: Professional electronics manufacturing environments often require compliance with international standards for ESD control to ensure product safety and quality.
• Monitoring the effectiveness of anti-static measures: Regular measurements help determine whether anti-static protective equipment (such as wrist straps, anti-static shoes, floor mats) is working effectively, and whether employees are following proper procedures.

To comply with the above standards, factories need to use specialized measuring equipment to assess and monitor static electricity levels. The most suitable equipment includes: 

• Electrostatic Field Meter / Non-contact Voltmeter:
  • Purpose: Measures electrostatic voltage on objects, surfaces or people without physical contact. This helps identify areas with high risk of static electricity.
  • Best fit: Handheld models such as SIMCO FMX-004 or DESCO, Katsuga models.

• Surface Resistance Meter:
  • Purpose: Measure the dissipative or conductive properties of materials (floors, carpets, clothing, packaging, footwear) to ensure they are within standard ranges (e.g., electrostatically dissipative materials typically have a resistance of 10610 to the sixth power106 to 101110 to the 11th power1011 Ohm).
  • Best fit: Models such as SIMCO ST-4, HOZAN F-109, DESCO 19290

• Wrist Strap & Footwear Tester:
  • Purpose: Quickly and daily check the grounding connectivity of employee wrist straps and antistatic shoes prior to entering the EPA area.
  • Best fit: DESCO 19271 Combo Tester X3 or integrated devices at the access control gate, electrostatic bracelet resistance meter HAKKO FG-470

• Ground Resistance Tester:
  • Purpose: Ensure the grounding system in the factory operates effectively and safely.
• HOZAN F-209 WRIST STRAP CHECKER

The combined use of these types of devices, along with a control program compliant with ANSI/ESD S20.20 or IEC 61340-5-1, will provide optimal control of the risk of electrostatic damage to electronic components.
