Supplier of Electronic Cleanroom Pass Boxes – Cross-Contamination Prevention, Anti-Static

Overview of Electronic Cleanroom Pass Boxes

A Pass Box (or cleanroom pass-through box) is an intermediary device installed between two areas with different cleanliness levels, ensuring that the transfer of items does not cause cross-contamination. This device operates via an interlock door mechanism, allowing only one door to open at a time, thereby minimizing infiltration of dust, microbes, or static charge.

Why Pass Boxes Matter in the Electronics Industry?

In electronics manufacturing—especially in sensitive fields like semiconductors, integrated circuits, and LCD/OLED panels—even a microscopic particle or electrostatic discharge (ESD) can cause serious defects. A Pass Box serves as a “control gate,” helping to:

• Minimize human traffic between clean zones, preserving cleanliness levels

• Prevent cross-contamination between production zones

• Protect components from ESD damage

• Increase equipment lifespan and reduce defect rates

Risks in Electronics Production and Their Effects

Using electronic / ESD-resistant Pass Boxes (e.g. anti-static coating, effective grounding, interlock control) is an optimal solution to manage these hazards efficiently and sustainably.

Applications of Pass Boxes in Electronics Factories

• Safe material/component transfer between clean zones: Factories often segment into multiple cleanliness classes (e.g. ISO Class 5 to 7). Pass Boxes are installed at interfaces, ensuring the movement of materials does not compromise cleanliness.

• Reduce staff movement, thus limiting cross-contamination

• Improve operational logistics within the facility

• Maintain ISO standards: Pass Boxes stabilize airflow, use interlock doors to prevent simultaneous opening, and can integrate HEPA filters or internal clean air flow.

• Protect electronics from ESD: ESD Pass Boxes use conductive or ESD coating materials, safe grounding systems, and smooth surfaces to dissipate charges.

• Remove ultrafine dust (PM0.3 – PM2.5): Integrate UV sterilization, clean air blowers, or HEPA filters to keep the internal environment controlled and free of particulates or microbes.

Types of Pass Boxes Suitable for the Electronics Industry

Depending on production requirements (cleanliness, ESD control, sterilization), typical Pass Box types include:

• Mechanical Pass Box
  – Mechanical interlock doors
  – No power required
  – Low cost and easy maintenance
  – For less stringent areas

• Electronic Pass Box
  – With UV sterilization lamps
  – Electronic door locking, alarms
  – Status displays
  – For more sensitive zones

• ESD / Anti-static Pass Box
  – Made of conductive or ESD-coated materials
  – Reliable grounding system
  – Non-charge accumulating surfaces
  – For IC, semiconductor, ESD-sensitive zones

Recommendation Guidelines:

• For module manufacturing → prioritize ESD Pass Box

• For quality inspection zones → use Electronic Pass Box with UV

• For general assembly → use Mechanical Pass Box for cost savings

Frequently Asked Questions (FAQ)

Is an ESD Pass Box different from a regular Pass Box?
Yes. An ESD Pass Box is constructed with conductive materials or an ESD coating to dissipate static charges, avoiding electrostatic discharges that could damage electronic components. A proper grounding system is essential.

How often should a Pass Box be maintained?
Depending on usage and environment, it is recommended to inspect and service every 3–6 months. Key checks include:

• Interlock door operations

• UV lamp sterilization (if equipped)

• HEPA filter condition

• Surface dust or charge accumulation

Can you order a custom Pass Box design?
Absolutely. VCR offers bespoke solutions including:

• Custom dimensions

• Material selection (SS304, SS316, ESD plastics)

• Add-on features (UV lamps, electronic interlock, LED displays, sensors, auto doors)
