Briefly describe the applications and precautions of burn-in test sockets.

　　1. Applications of Burn-In Test Sockets
　　1. Durability Testing of Electronic Products: Durability testing is an important method for evaluating the long-term performance of electronic products. Burn-in test sockets can simulate various environmental conditions to test the durability of electronic products and determine their long-term reliability.
　　2. Reliability Testing of Electronic Products: Burn-in test sockets can simulate various environmental conditions to test the reliability of electronic products and determine their level of reliability.
　　3. New Product Development: Burn-in test sockets can simulate various environmental conditions, helping R&D personnel better understand the performance of new products and thereby improve product design.
　　2. Precautions for Using Burn-In Test Sockets
　　1. Before operation, inspect all components of the burn-in test socket to ensure they are in good condition, preventing unnecessary losses.
　　2. During operation, ensure a stable power supply to avoid test result deviations caused by power fluctuations.
　　3. Avoid prolonged continuous loading during operation, as this may affect test results.
　　4. During operation, regularly check the power module and controller of the burn-in test socket to ensure they are functioning properly.
　　5. During operation, regularly check the temperature control module and humidity control module of the burn-in test socket to ensure they are working correctly.
