A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.
In 1991, a startup QuadTech [3] was founded as spinoff of GenRad's Instrumentation division and Precision Product lines, as well as the rights to use the "GenRad" and "General Radio" names. In 2000, IET Labs [ 4 ] acquired from QuadTech the GenRad RLC standards, impedance decades, megohmmeters, digibridges, audio lines, stroboscope lines.
Test automation is a big part of a test engineer's job. The whole intention of automating the test is as follows: Enforce test steps to be followed within specifications and correct timing. Eliminate manual command and data inputs. Automate data gathering. Enforce test process flow.
In 2000, Teradyne Connection Systems acquired Herco Technologies and Synthane-Taylor, and a year later they acquired circuit-board test and inspection leader, GenRad, and merged it into the Assembly Test Division. GenRad's Diagnostic Solutions, which made test equipment for the automotive manufacturing and service industries, became a separate ...
Software which is used to run reproducible tests systematically on a piece of software under test is known as a test harness; part of its job is to set up suitable test fixtures. In generic xUnit, a test fixture is all the things that must be in place in order to run a test and expect a particular outcome. [10]
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.

Bead probe technology is a probing method used to connect electronic test equipment to the device under test (DUT) within a bed of nails fixture. The technique was first used in the 1990s [3] and originally given the name “Waygood Bump” after one of the main proponents, Rex Waygood.
Flying probes were introduced in the late 1980’s and can be found in many manufacturing and assembly operations, most often in manufacturing of electronic printed circuit boards. A flying probe tester uses one or more test probes to make contact with the circuit board under test; the probes are moved from place to place on the circuit board ...
