ESD Wrist Strap and Grounding Control System in Electronics Manufacturing

In the modern electronics industry, ESD—electrostatic discharge—is one of the leading causes of component damage, reduced product quality, and production interruptions. Even a small discharge invisible to the naked eye can cause billions of dollars in losses each year.

Recognizing this critical issue, INDEX Technology Co., Ltd offers a specialized solution for wrist strap and grounding control, enabling continuous and precise monitoring of contact between operators and the grounding system, including:

  • Anti-static wrist strap tester

  • Personal and workstation grounding tester

  • Real-time monitoring system with the ability to record and issue alerts in case of connection faults or non-compliance

1. System Functions

  • Electrostatic discharge and grounding: The wrist strap serves as a bridge, transferring static charges accumulated on the operator’s body to the central grounding system.

  • Real-time connection monitoring: The ESD monitor continuously checks the connection status between the wrist strap – operator – grounding cord, ensuring the system operates reliably.

  • Grounding loss alarm: If the operator removes the wrist strap, wears it incorrectly, the cord is broken, or contact with the grounding system is lost, the device will trigger an alert via indicator lights and the display screen, prompting immediate corrective action.

3. Key Advantages

  • 24/7 real-time operation, preventing situations where employees wear wrist straps superficially without actual contact.

  • Visual alerts that help managers easily detect connection loss.

  • Easily expandable for production lines with multiple operators.

  • Optional alerts connected to computers/peripheral devices, with event history tracking support.

  • Data storage on server or SQL databases, with export capability to Excel.
