Production testing is a type of testing performed on silicon chips and integrated circuits during the manufacturing process to verify that they meet required performance and functionality specifications. The purpose of production testing is to ensure that only high-quality, functional devices are used in finished products, and to minimize the risk of defects in the field.
Production testing typically includes a combination of functional testing, parametric testing, and reliability testing. During functional testing, each device is subjected to a series of tests to verify that it performs its intended functions correctly. During parametric testing, each device is tested for key electrical parameters, such as voltage, current, and capacitance. During reliability testing, each device is subjected to a series of tests designed to simulate real-world operating conditions, including temperature, voltage, and stress conditions.
Production testing is an important step in the manufacturing process of silicon chips and integrated circuits, as it helps to ensure that only high-quality, functional devices are used in finished products. By identifying and eliminating defective devices, production testing helps to reduce the cost of the manufacturing process, improve the reliability and performance of the final product, and reduce the number of warranty claims and returns from customers.
