PCB test points are special points reserved on the printed circuit board (PCB) for electrical measurement, signal transmission and fault diagnosis.
Their functions include: Electrical measurements: Test points can be used to measure electrical parameters such as voltage, current, and impedance of a circuit to ensure proper operation and performance of the circuit.
Signal transmission: The test point can be used as a signal pin to connect to other electronic equipment or test instruments to realize signal input and output.
Fault diagnosis: When a circuit fault occurs, test points can be used to locate the fault point and help engineers find the cause and solution of the fault.
Design verification: Through test points, the accuracy and functionality of the PCB design can be verified to ensure that the circuit board works according to the design requirements.
Quick Repair: When circuit components need to be replaced or repaired, test points can be used to quickly connect and disconnect circuits, simplifying the repair process.
In short, PCB test points play an important role in the production, testing and repair process of circuit boards, which can improve work efficiency, ensure quality, and simplify troubleshooting and repair steps.
