The two rows of holes (labelled #3) are test points used during the manufacture of this USB memory key. Testpoints on a printed circuit board (labelled E34, E35, E36, …) next to teardrop vias. A test point is a location within an electronic circuit that is used to monitor the state of the circuitry or inject test signals. [1]
In telecommunications, a transmission level point (TLP) is a test point in an electronic circuit that is typically a transmission channel. At the TLP, a test signal may be introduced or measured. [1] Various parameters, such as the power of the signal, noise, voltage levels, wave forms, may be measured at the TLP. [2]
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.
