Electronics ESD Protection Solution

💻

Solution Overview

Yield Protection & ESD Compliance

🏆

Yield Protection

ESD events cause 25-35% of electronic component failures. Real-time monitoring and grounding verification reduce ESD-related defects and improve production yield.

🛡️

Compliance Assurance

IEC 61340-5-1 and ANSI/ESD S20.20 certified equipment ensures your EPA (ESD Protected Area) meets international standards for customer audits.

💰

Cost Reduction

Prevent costly ESD damage to sensitive components. A single ESD event can destroy components worth thousands of dollars — proactive monitoring pays for itself quickly.

Selection & Deployment

Selection Recommendations

01

EPA Zoning Strategy

Define EPA boundaries based on component sensitivity class (Class 0: <250V, Class 1: 250-499V, Class 2: 500-999V). Higher sensitivity requires stricter controls and more frequent testing.

02

Wrist Strap Testing Frequency

Test wrist straps at least once per shift (every 8 hours). Use continuous wrist strap monitors for Class 0 components. Document all test results for audit trail.

03

Ionizer Selection

Select ionizers based on work area size and airflow. Verify ionizer performance monthly with charge plate monitor. Balance voltage should be within ±35V for standard EPA.

04

Environmental Control

Maintain relative humidity 30-70% in EPA. Use humidity loggers for continuous monitoring. Low humidity (<30% RH) significantly increases ESD risk and requires additional controls.
