5. Quality inspection

Strict quality inspection is carried out during the production process to ensure that each piece of Dummy Silicon Wafer meets the quality standards. This strict quality inspection process ensures the high standards and consistency of the products and provides customers with reliable products.

6. Packaging and Storage

Use appropriate packaging and storage methods to protect Dummy Silicon Wafer from damage during transportation and storage. This proper packaging and storage method not only protects the product, but also ensures that it remains in the best condition when it reaches the hands of customers.

1. Equipment calibration: The accuracy and stability of equipment are crucial in the semiconductor manufacturing process. Dummy Wafer, as an important tool for equipment calibration and verification, can simulate the operating status of real wafers in the equipment, helping engineers accurately evaluate the performance of the equipment. By using Dummy Wafer for equipment calibration, it is possible to ensure the accuracy of various parameters during the manufacturing process, thereby improving product quality and production efficiency.

2. Process optimization: Dummy Wafer plays a crucial role as a test sample in developing new processes or optimizing existing processes. Engineers can adjust and optimize various process parameters on Dummy Wafer, observe and analyze the impact of different parameters on the wafer manufacturing process. This Dummy Wafer based process optimization method can reduce the risk and cost of directly operating real wafers, while improving the efficiency and success rate of process development.

3. Production line testing: Regular testing on the production line is an important means of evaluating the stability and reliability of the production line. Dummy Wafer can be used as a test sample to simulate the operation process of real wafers on the production line, helping engineers discover problems and hidden dangers in the production line in a timely manner. Regular testing and evaluation of the production line can ensure its stable operation, improve product yield and production efficiency.

4. Training and teaching: For new employees, quickly familiarizing themselves with semiconductor manufacturing processes and operating standards is crucial. Dummy Wafer, as a teaching tool, can visually demonstrate the various stages and operational points in the wafer manufacturing process. Through practical operation of Dummy Wafer, new employees can gain a deeper understanding of the principles and processes of semiconductor manufacturing, and improve their operational skills and levels.

5. Quality control: Using Dummy Wafer in the quality control process can ensure that the product meets relevant standards and requirements. By conducting various tests and inspections on Dummy Wafer, the quality control effectiveness during the production process can be evaluated, and quality issues can be identified and corrected in a timely manner. This Dummy Wafer based quality control method can improve product quality and stability, enhance customer trust and satisfaction with the product.

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.
