Wafer Carrier Trays Structure:
2 series of wafer carrier trays:
2. Anti-Static Black Polypropylene Series
Specifically developed for static-sensitive processes or applications requiring light shielding (such as photoresist-coated wafers), these trays are crafted from anti-static black polypropylene. Infused with carbon materials, the trays achieve a surface resistivity of 10⁴–10⁵ Ω/cm² and volume resistivity of 10⁴ Ω/cm, delivering exceptional ESD (Electrostatic Discharge) protection to prevent wafer damage from charge accumulation. The black material simultaneously forms a natural light-shielding layer, safeguarding photoresist from accidental exposure during transportation and storage.
With stable performance in high-cleanliness environments, these trays are ideal for laboratory wafer transportation, combining edge-support design and spring-locking mechanisms to ensure secure handling.

The Ultimate FAQ Guide:
1. What are the common materials for Wafer Carrier Trays?
Common materials for Wafer Carrier Trays include quartz, silicon carbide, ceramic, polytetrafluoroethylene (PTFE), and silicon. Different materials are suitable for various process environments. For example, quartz has high temperature resistance and strong chemical stability, making it suitable for high – temperature processes; ceramic features good abrasion resistance and low hygroscopicity.
2. How do I choose a carrier tray suitable for my wafer size?
Wafer sizes mainly include 4 – inch, 6 – inch, 8 – inch, and 12 – inch. When choosing, you need to match the corresponding tray specifications according to the actual wafer size. Also, consider parameters such as the tray’s slot depth and spacing to ensure the wafers are placed stably without friction.
3. What is the service life of Wafer Carrier Trays?
The service life of the tray is affected by factors such as usage frequency, environmental conditions (such as temperature, humidity, corrosive gases), and operating specifications. Under normal circumstances, high – quality trays can be used for 1 – 3 years. If used in harsh environments, more frequent replacements may be required.
4. Can wafer carrier trays withstand high - temperature processes?
Trays made of certain materials (such as quartz and ceramic) can withstand high temperatures, with a maximum tolerance of over 1200°C. However, the specific temperature tolerance should be referred to in the product specification sheet to ensure it meets the process requirements.
5. How to clean and maintain Wafer Carrier Trays?
Generally, use a cleanroom wipe with a special cleaning agent to wipe off surface stains. For stubborn dirt, ultrasonic cleaning can be used. Avoid using sharp tools to scratch the surface. After cleaning, dry the tray in a cleanroom environment to prevent secondary contamination.
6. How is the anti - static performance of the tray ensured?
Anti – static trays are usually made of anti – static materials or coated with an anti – static layer on the surface. During the production process, strict anti – static tests are carried out to ensure that the surface resistance value meets industry standards (such as 10⁶ – 10¹²Ω).
7. Do you provide customized Wafer Carrier Trays services?
We offer customization services. We can design and produce exclusive trays according to customers’ requirements for wafer size, special process requirements (such as high – temperature resistance, anti – static level), and loading quantity.
8. Are there discounts for bulk purchases of Wafer Carrier Trays?
Bulk purchases can enjoy tiered discounts. The specific discount rate depends on the order quantity and product type. For details, please contact our sales team for a quote.
9. What is the delivery time for the products?
Standard products are usually shipped within 7 – 15 working days. The delivery time for customized products will be evaluated according to the complexity, generally 20 – 45 working days.
10. Is the packaging of Wafer Carrier Trays suitable for long - distance transportation?
We use anti – static and cleanroom packaging and fill it with cushioning materials to ensure that the trays are not damaged by vibration and extrusion during transportation. At the same time, the packaging meets international transportation standards and can be safely delivered worldwide.
