3. High Hardness: Sapphire wafers are extremely hard, making them resistant to scratches and wear. This high hardness contributes to their longevity and durability in harsh environments.

4. Chemical Stability and Corrosion Resistance: Single crystal sapphire is highly resistant to chemical corrosion, ensuring long-term reliability even in the presence of aggressive chemicals or extreme environmental conditions.

5. Customizable Sizes and Thicknesses:  Single crystal sapphire wafers are available in various sizes and thicknesses, making them versatile for different industrial and research applications. Custom specifications are available to meet specific project requirements.

Semiconductor silicon wafer is the upstream of integrated circuit industry and is an important material for manufacturing integrated circuits.

Semiconductor silicon wafer manufacturing technology is difficult, the downstream application is wide, the market value is high, is the main application field of silicon wafer. Silicon is the starting point of the semiconductor industry chain, through the front and back of the entire chip manufacturing process, without silicon semiconductor industry will be like water without a source. The output and quality of silicon wafers directly restricts the entire semiconductor industry, and the development of many industries such as communications, automobiles, and computers further downstream, and is a key material for manufacturing chips.

Semiconductor products are mainly used in computer, household appliances, digital electronics, electrical, communications, transportation, medical, aerospace and many other fields.

The packaging should be able to withstand the impact, vibration, stacking and extrusion that may be encountered during transportation, while also it has to easy to load, unload and handle.

We use professional wafer box packaging. The wafer box is protected by a double layer bag, the inside is a PE bag that can be dust-proof, and the outside is a aluminum foil bag that can be isolated from the air. The two-layer bags are vacuum-packed. 

We will choose carton models according to different sizes of products. And between the product and the carton filled with shock-proof EPE foam, play a comprehensive protection. 

Finally choose air transport to reach the customer's hands. This allows customers in any country and region to receive the product in the fastest time.

We comply with the Material Safety Data Sheet (MSDS) rules to ensure that the products transported are free of harmful substances and will not cause environmental pollution and explosion and other possible hazards.
