Typical passive oscilloscope probe being used to test an integrated circuit. A test probe is a physical device used to connect electronic test equipment to a device under test (DUT). Test probes range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile.
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.
Advanced Tester Resource Enhancement (ATRE) [5] is a powerful means of increasing the number of DUTs that can be tested by a probe card in parallel (or in one touchdown during which probe card needles remain in contact with the wafer DUTs). ATRE allows the sharing of tester resources among DUTs using active components, which have the ability to ...
the probe will act as a circuit and affect the results of the test. For this reason, the tests performed at wafer sort cannot always be identical and as extensive as those performed at the final device test after packaging is complete [3] since the probe pads are typically on the perimeter of the IC, the IC can soon become pad-limited.
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 numerous 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.
The following are used for stimulus of the circuit under test: Power supplies; Signal generator; Digital pattern generator; Pulse generator; Voltcraft M-3850 portable multimeter. The following analyze the response of the circuit under test: Oscilloscope (Displays voltage as it changes over time) Frequency counter (Measures frequency)
