About Electronics Test Fixtures
Electronics test fixtures are used to test contact points on circuit boards during manual or automated testing. Products are used to test daughter cards, flex circuits, liquid crystal displays (LCDs), loop-back boards, multi-chip modules, optical packages, printed circuit boards (PCBs), radio frequency (RF) modules, and hybrid boards. Electronic test fixtures are also used to test integrated circuits (ICs). Typically, automated test equipment (ATE) is attached to an interface between the IC and a device under test (DUT) board. As a rule, DUT boards are designed to meet the all of the mechanical and electrical requirements of both IC chips and electronic test fixtures.
There are many types of electronics test fixtures. Examples include manufacturing defect analyzers, in-circuit testers, and functional analyzers. Manufacturing defect analyzers (MDAs) or analog circuit testers are used to identify and locate defects such as shorts and missing components. Because the unit under test (UUT) is powered-down, however, MDAs are not designed for testing digital ICs. In-circuit analyzers or digital circuit testers are used for testing components that are part of a board assembly. Because the UUT is powered-up or hot, the components under test are considered to be in a circuit. Functional analyzers or emulators are electronics test fixtures that simulate an operating environment. They are used for testing boards against their functional specifications.
