Summarize and describe future trends
Electrical testing of components and system boards is required to guarantee their operation. A systematic process involves testing at every step to guarantee the functionality and performance of the component before it is committed to the next step and ultimately to the final product. This chapter describes various tests that are typically performed from the wafer level to the system-level board.
Electrical testing is the process by which an electronic, photonic, or MEMS device, or the systems in which they are used, is guaranteed to be electrically functional before it is put to end-product use. This is done by applying controlled electrical stimuli to a circuit and comparing its response with an allowed range of expected responses. The objective of electrical testing is to verify that the circuit functions correctly.
Close analogies can be made between the everyday meaning of test and the more specific use when applied to electronic systems. Consider how the term test applies to the process of selecting a new car. For example,...
