Why do PCB boards need to have test points?
Why do PCB boards need to have test points?
The purpose of setting up test points is to test whether the components on the circuit board meet the specifications and solderability. For example, if you want to check whether the resistance on a circuit board is faulty, the easiest way is to measure it with a multimeter. Then can know.
However, if the probe directly contacts the electronic parts on the board or its solder feet, it is likely to crush some electronic parts, but it is counterproductive, so there is a test point, and a pair of circular small pins are drawn at both ends of the part. The dots, without a solder mask, allow the test probes to touch these small dots without directly touching the electronic parts being measured.
