Using EIESD Ionizing Bars in Electronics Manufacturing

Using EIESD Ionizing Bars in Electronics Manufacturing

1. Introduction

Static electricity can damage sensitive electronic components (ICs, semiconductors, PCBs).

Ionizing bars neutralize static charges by emitting positive and negative ions, preventing ESD (Electrostatic Discharge) events on surfaces and equipment.

Ionizers are widely used in:

SMT assembly lines

PCB manufacturing

Electronics packaging and testing areas

2. Benefits in Electronics Workshops

Benefit Explanation

Prevents ESD damage Neutralizes static charges on components, tools, and work surfaces

Improves product yield Reduces defects caused by static-sensitive ICs

Maintains cleanroom compliance DC/pulsed DC ionizers produce minimal ozone and particulates

Safe for operators Low current output prevents electrical hazards

3. Recommended Ionizer Types

Type Application Notes

DC / Pulsed DC bar Preferred in electronics production: low ozone, stable ion balance

AC ionizer Can be used, but generates more ozone; less suitable for confined cleanrooms

Air-assisted / blower bar Ideal for large boards or moving conveyors, ensures ions reach the entire surface

4. Installation Guidelines

Distance from target surface

Typical: 20–50 cm for small boards; 30–100 cm for conveyors.

Orientation

Bars should cover the width of the work area for uniform ion distribution.

Grounding

Bar and power supply must be properly grounded to maintain stable ion output.

Ventilation

Minimal airflow disruption to avoid uneven ionization or dust deposition.

Avoid direct contact

Prevent operators from touching emitter pins to ensure safety.

5. Maintenance in Electronics Workshops

Task Frequency

Clean emitter pins Weekly (normal production) or more in dusty environments

Inspect grounding Monthly

Check ion balance / decay time Quarterly or after cleaning

Monitor ozone and EMF if necessary For sensitive cleanrooms, periodically

Regular maintenance ensures consistent ion balance and fast static decay, which is critical for sensitive electronics.

6. Environmental Considerations

Factor Recommended Setting

Humidity 40–60% RH to prevent static buildup

Temperature Within manufacturer specs (typically 20–25°C)

Cleanliness Filtered airflow to minimize dust on emitter pins

Ozone Prefer DC/pulsed DC bars in confined cleanrooms

7. Safety Considerations

Ionizer output current is low → safe for operators.

Ozone levels are minimal if DC/pulsed DC bars are used.

EMF emissions are low but keep sensitive electronic measuring devices a safe distance away.

8. Summary

Aspect Recommendation for Electronics Workshop

Ionizer type DC or pulsed DC preferred; AC only if ventilation is sufficient

Placement Cover entire work area; maintain 20–50 cm distance from boards

Grounding Must be properly connected

Maintenance Clean pins regularly; check ion balance and decay time

Environment RH 40–60%, filtered airflow, low dust

Safety Low current output; minimal ozone; EMF negligible at working distance

Key Takeaways:

Ionizing bars are highly suitable for electronics manufacturing.

Proper installation, grounding, and maintenance ensure ESD protection and product quality.

DC/pulsed DC ionizers are ideal for cleanroom or sensitive electronics applications.
