   Test Platform / System       A piece of electronic equipment designed to test chips to check if they work, and if so, how well (usually how fast) they work. Testers are usually specialized as either memory chip testers, digital logic chip testers, or analog chip testers, though some of the more sophisticated testers can deal with more than one of these groups.  Testers consist of a test control unit or panel and test head.  Testers are used in conjunction with interfaces, source and measure units, handlers or probers. The interface or connection system to provides electrical paths to the device under test (DUT) for stimuli (input) signals and measurement (output) signals. Source units provide a source signal or stimuli input. Measurement units measure the output signal from the component or DUT. 
   Test Module / Sub-system       Test modules, sub-systems or units include load banks; gas supply systems; test controllers; meters, monitors, data acquisition unit or measurement modules; ovens, chillers or other temperature controllers; and moisture or humidity controllers.

Test / Technique
   Tester / Test Capability:       
   Your choices are...         
   Functional Test (Performance)       A functional test simulates an operating environment and tests a board against its functional specification.   The functional test method applies pattern vectors to a device and checks the output to determine that the device is operating according to its truth table. 
   Life / Endurance Testing       Test equipment can perform life or endurance testing. Life testing may be conventional or highly accelerated to reduce test time. 
   Parametric / In-process       Parametric, wafer sort or other in-process tests are the measurement and verification of terminal voltage and current characteristics at a device pin. 
   Manufacturing Defect Analyzer (MDA)       Manufacturing defects are detected using manufacturing defect analyzers (MDAs), such as shorts and missing components, but they cannot test digital ICs as they test with the unit under test (UUT) powered down (cold).  As a result, they assume the ICs are good.  MDAs are also referred to as analog circuit testers.  
   In-Circuit Tester (ICT)       This type of test tests components that are part of a board assembly.  The components under test are "in a circuit."  The unit under test (UUT) is powered up (hot).  Also referred to as digital circuit testers. 
   Simulation / Emulation       Test systems that provide simulation or emulation of a product in order to test a component interfacing with the simulated or emulated product. An emulator is a device, computer program, or system that accepts the same inputs and produces the same outputs as a given system. 
   JTAG / Boundary-Scan       JTAG or boundary scan test methodology allows complete controllability and observability of the boundary (I/O) pins via a standard interface.  With boundary-scan testing the user can test interconnections on PCBs without using a probe on each node. Evaluations may include device level testing as well as mixed, real, and virtual pin circuit tests. JTAG is an acronym for Joint Test Action Group ("jay-tag"). Originally, JTAG was the name of the team developing the method, now the term has come to be associated with the output of the team. JTAG is now essentially synonymous with the IEEE 1149.1 standard for Test Access Port and Boundary Scan. 
   Vectorless (e.g., Q-test)       Vectorless test do not use a pattern vector test method as is applied in the functional test process. Aeroflex's Q-testsTM methodology is an example of the vectorless test method for detecting open-circuits, which form a large category of manufacturing faults.  Vectorless or Q-testsTM test methods detects open-circuits on custom or complex devices where no access or data is available for full test generation. Vectorless tests typically use either capacitive or inductive probing techniques.  
   Vision / X-ray       X-ray instruments and optical or vision inspection systems are used to detect physical surface or sub-surface defects. Optical inspection methods include scanning probe microscopes to reveal surface defects. X-ray inspection instruments can detect sub-surface defects by looking through insulation layers that are optically opaque.  X-ray and optical inspections don't need test fixtures and require no electrical sources or measurements to find open connections or shorts.  However, some optical or thermal imaging instruments are coupled with electrical sources to find hot spots in circuits.

   DUT Interfacing / Adapters:       
   Your choices are...         
   Bed-of-Nails (BON) / Grid       Each circuit net on the board is connected to the tester, typically with one nail per net. BONs typically require a vacuum or air source. 
   Flying Prober / Scanner       Also known as a flying probe or floating probe. Flying probers are used for open and shorts testing. The flying probe system uses a low number of moving probes rather than the high number of fixed probes in the BON.  Test times may be slower due to probe movements, but the method has compensating benefits. In practice, a flying probe can provide close to 100% test coverage on a board with thousands of nets of passive components and hundreds of digital devices 
   Optical Connector       Optical connections or interfaces are utilized for evaluation of optoelectronic, fiber optic or photonic equipment.
