Test Points

Test points are integral tools explicitly designed to provide a physical connection for test equipment. They are distinct from simple test pads or vias used for internal circuit probing. Test points are specialised components created for robust and reliable joints during testing and measurement. Test points indeed establish an electrical connection between test equipment (such as oscilloscopes, multimeters, and logic analysers) and an electrical circuit.Purpose of UseTest points are primarily us...

Purpose of Use

Test points are primarily used for connecting test equipment to the circuit, allowing measurements and signal injections. They are built to handle repeated connections and disconnections without damaging the PCB or the circuit.

The most common accessories of test points include:

Jack: Refers to test point jacks designed to receive standard test probes.
Compact: Smaller versions for space-limited applications.
Large Profile: Larger, more powerful versions for heavy-duty testing.
Loop: Boasts a loop for tight connection with hook-type probes.
Low Profile: Built for minimal height above the PCB surface.
Miniature: Very small test points for denser circuit boards.
Multipurpose: Designed to house various types of test probes.
R/A (Right Angle): Created for connections at a right angle to the PCB.
R/A Double Loop: Right-angle versions with a double loop for safer connections.
Slotted: Feature a slot for accepting specialised test probes.
Standard Hook: Designed for standard hook-type test probes.

Where Can I Use Test Points?

In-Circuit Testing (ICT): Allows for automated testing of component values, connectivity, and circuit functionality.
Functional Testing: After assembly, functional testing verifies that the entire assembled product works as intended.
Boundary Scan Testing: Access the boundary scan chain of integrated circuits, allowing for testing of interconnections between chips.
Circuit Debugging: During the design and prototyping phases, engineers use test points to probe signals and troubleshoot circuit issues.
Signal Integrity Testing: Allow engineers to measure signal characteristics such as reflections, crosstalk, and noise to confirm proper signal transmission.
Calibration & Adjustment: Provide access to calibration points or adjustment potentiometers.

Summary

Test points are pivotal during the design, prototyping, and manufacturing processes of electronic products. They ensure that circuits can be quickly and reliably tested, resulting in higher product quality and minimised development time.
