MC-4AFD 4.00” Soft Wafer Cushion Disc

Detailed Product Description

The Soft Wafer Cushion MC-4AFD is a 4.00-inch diameter, 0.25-inch thick open-cell antistatic foam disc designed to help protect semiconductor wafers and other delicate substrates during storage, handling, and transportation. Manufactured from resilient antistatic polyurethane foam, this wafer cushion provides reliable ESD-safe cushioning while helping reduce the risk of abrasion, vibration transfer, and surface damage within horizontal wafer packaging systems.

Its soft, compliant foam structure provides controlled cushioning for sensitive wafers while maintaining dimensional consistency for integration into wafer jars, wafer carriers, wafer shippers, and related semiconductor packaging assemblies. The antistatic material formulation helps dissipate electrostatic charges that could damage sensitive electronic devices and semiconductor components.

The Soft Wafer Cushion MC-4AFD is suitable for contamination-sensitive environments where clean handling, reliable cushioning, and ESD protection are important throughout storage and transportation processes.

Practical Applications

The Soft Wafer Cushion MC-4AFD is designed for use throughout semiconductor packaging and wafer handling operations.

• Provides ESD-safe cushioning for semiconductor wafers during storage and transport.
• Helps reduce scratching, abrasion, and handling damage to delicate wafer surfaces.
• Suitable for wafer jars, wafer shippers, wafer carriers, and horizontal wafer systems.
• Supports contamination-conscious semiconductor packaging applications.
