Flying Probe Testing For PCB Assembly
Flying probe testing, because the name implies uses test probes that “fly” i.e., the test probes move from test points to other test points as per instructions given by the precise software program that's written for the board under test. No custom fixture is required, so it could even be called a fixtureless in-circuit test if used on an assembled PCB. Hence, it's highly cost-effective for prototypes and low to mid-volume production. The flying probe testers originally evolved to be used just for bare board testing, and they became the de-facto standard for bare-board testing (which involves testing for shorts, opens, etc. between copper conductor features on the bare PCB) where the most electrical parameter that's measured is that the resistance between two points or nodes. - https://www.jhypcba.com
