Reliability testThe purpose of reliability test on Siliup products is to find out the weak points, to understand, verify, evaluate, analysis and improve the reliability of products. Different levels of chips will work under different application environments. The more complex the application environment, the requirements on reliability will be higher and stricter. All our products have been tested strictly before shipment to ensure that the products delivered to customers are verified. However, in order to evaluated the performance after working long times, further reliability tests are needed to simulate the impact of some harsh service conditions on the products in actual environment, so as to evaluate the service life and possible risks of the chip and improve the product performance.
Test itemsDifferent grades of products have different requirements. The purpose of reliability test is to prove that they meet the classification standards. The test items of reliability test are designed according to the specific application environment of different levels of products, simulate the environmental factors of products in normal use, and verify their functional consistency and durability.
