Product Overview

The 1.5-inch wafer cassette box is a compact, precision-engineered storage and transport container specifically designed for miniature wafers, substrates, and delicate semiconductor samples. Manufactured from high-purity polypropylene (PP) or polycarbonate (PC), the cassette box ensures excellent mechanical stability, chemical resistance, and cleanroom compatibility. Its design meets the stringent cleanliness and handling standards required in semiconductor fabrication, optical component production, and MEMS research.

Unlike standard 4–12 inch wafer carriers, the 1.5-inch model is tailored for prototype development, small-die testing, and advanced R&D laboratories, where smaller substrates demand equal levels of protection and precision.

Key Features

• Compact Design: Optimized for 1.5-inch wafers, ensuring perfect alignment and secure stacking.

• High-Purity Materials: Constructed from cleanroom-grade PP or PC, resistant to acids, bases, and organic solvents.

• Smooth Inner Surface: Minimizes particle generation and mechanical stress on wafer edges.

• Anti-Static & Contamination Control: Optional ESD-safe materials to protect sensitive electronic devices.

• Secure Locking Mechanism: Snap-fit or screw-lock lid for stable sealing during transport and storage.

• Traceability Options: Laser marking or serial number engraving available for process tracking.

• Temperature Resistance: Withstands temperatures from -20°C to +120°C without deformation.

Typical Specifications

• Optional customization: logo printing, special slot numbers, or anti-static coatings.

FAQ

Q1: Can the cassette be used in a Class 100 cleanroom?
A1: Yes. All models are produced from cleanroom-grade PP or PC materials suitable for ISO Class 5 (Class 100) environments.

Q2: Is it compatible with automation equipment?
A2: Certain versions are compatible with robotic arms and standard wafer handling tools upon request.

Q3: Can I customize the slot spacing or material color?
A3: Yes, slot pitch, lid design, and color can be tailored to your specifications.

Q4: What cleaning method is recommended?
A4: The cassette can be cleaned using DI water rinse or ultrasonic cleaning under low temperature, then dried in filtered air.
