Background
Some customers require us to provide ESD covers for PCB magazines on the shop floor, in order to prevent dust contamination on PCB panels.
Requirement
- Need ESD cover with double quick-access design (Four zippers or fast opening)
ESD Cover Size Requirements
PCB Magazine Cover Sizes:
- 40 × 56 × 46 cm (Width × Height × Depth)
- 46 × 57 × 54 cm
- 32 × 57 × 71 cm
Shelf Cover Size:
- 62 × 100 × 200 cm
Solution Response
After reviewing the customer’s situation and photos, we found that the structure is a mesh-style cover, but similar cases from our customers showed the same issue:
Even mesh covers can still allow dust contamination, which affects PCB cleanliness.
Because of this, many customers eventually switched to cleanroom-grade ESD covers.
Recommended Solution: Cleanroom ESD Covers
We recommend fully enclosed ESD covers for PCB magazines and shelves.
Product Features:
- All four sides equipped with zippers for easy access
- Material: Conductive polyester fabric (68D × 75D)
- Suitable for Cleanroom Class 10–100 environments
- Soft, breathable, and dust-free
- Permanent anti-static performance: 10⁶ ~ 10⁹ Ω
- Washable and reusable without performance degradation
Applications:
- Cleanroom garments
- Antistatic clothing
- PCB magazine covers
- Shelf protective covers
- Cleanroom storage protection
ESD Cover Selection Guide (Before Purchase)
1. Anti-static Performance Requirement
In SMT environments, resistance should typically be:
👉 10⁶ Ω to 10⁹ Ω
Ordinary fabric or plastic materials are NOT suitable because:
- They generate static electricity
- They attract dust
- They may damage or discharge PCBs
2. Opening & Accessibility Design
Since operators open and close covers frequently (10+ times per day), the design must be practical:
- Zippers or Velcro recommended
- Smooth opening/closing improves efficiency
- Easier PCB loading and unloading
3. Custom Size Requirement
ESD covers must be fully customized based on equipment size.
Please provide:
- Length
- Width
- Height
of PCB magazine or shelf for accurate production.
4. Cleaning & Maintenance
The conductive polyester fabric is:
- Washable with water
- Fast-drying
- Durable for long-term use
- Maintains stable anti-static performance after repeated cleaning
Conclusion
For SMT factories dealing with PCB magazine storage and dust control, mesh covers are often not enough.
A properly designed cleanroom-grade ESD cover from Feedersmt provides a more reliable and long-term protection solution.
