2. In-circuit testing - Wikipedia

   en.wikipedia.org/wiki/In-circuit_testing

   While in-circuit test is a very powerful tool for testing PCBs, it has these limitations: Parallel components can often only be tested as one component if the components are of the same type (i.e. two resistors); though different components in parallel may be testable using a sequence of different tests - e.g. a DC voltage measurement versus a measurement of AC injection current at a node.

3. Bead probe technology - Wikipedia

   en.wikipedia.org/wiki/Bead_probe_technology

   Bead probe technology (BPT) is technique used to provide electrical access (called “nodal access”) to printed circuit board (PCB) circuitry for performing in-circuit testing (ICT). [1] [2] It makes use of small beads of solder placed onto the board's traces to allow measuring and controlling of the signals using a test probe. This permits ...

4. Circuit Check - Wikipedia

   en.wikipedia.org/wiki/Circuit_Check

   Circuit Check was founded in 1978 as a spin-out of a printed circuit board drilling service bureau, "CircuitDrill." The initial product was test fixtures for bed of nails testers. Over the following years, the company developed innovations for in-circuit test and functional test or FCT. One, the pneumatically-actuated "clamshell" test fixture ...

5. Bed of nails tester - Wikipedia

   en.wikipedia.org/wiki/Bed_of_nails_tester

   Spring loaded pins are a component of the bed of nails tester. A bed of nails tester is a traditional electronic test fixture used for in-circuit testing.It has pins inserted into holes in an epoxy phenolic glass cloth laminated sheet (G-10) which are aligned using tooling pins to make contact with test points on a printed circuit board and are also connected to a measuring unit by wires.

6. Flying probe - Wikipedia

   en.wikipedia.org/wiki/Flying_probe

   One limitation in flying probe test methods is the speed at which measurements can be taken; the probes must be moved to each new test site on the board, and then a measurement must be completed. Bed-of-nails testers touch each test point simultaneously and electronic switching of instruments between test pins is more rapid than movement of probes.

7. ecu.test - Wikipedia

   en.wikipedia.org/wiki/Ecu.test

   ecu.test automates the control of the whole test environment and supports a broad range of test tools. Various abstraction layers for measured quantities allow its application on different testing levels, e.g. within the context of model in the loop, software in the loop and hardware in the loop as well as in real systems (vehicle and driver in the loop).
