Integrated Circuit Testing is the process of evaluating the performance and functionality of integrated circuits (ICs) to ensure they operate correctly. This testing is crucial in the manufacturing process, as it helps identify defects or issues that could affect the reliability of electronic devices. Various methods, such as functional testing and parametric testing, are employed to assess different aspects of the ICs. During testing, specialized equipment is used to apply signals and measure responses from the ICs. The results are analyzed to determine if the circuits meet the required specifications. Effective testing helps maintain quality and reduces the risk of failures in products like smartphones and computers.
