In the early days of the circuit boards, they were the days of the traditional through hole (DIP). The soldering pins of the parts would be used as test points, because the soldering pins of the traditional parts were strong enough to be unafraid of needles. However, there is often a miscalculation of poor probe contact, because electronic component is soldered by wave soldering (wave soldering) or SMT, a film of tin paste flux is usually formed on the surface of the solder. The film's impedance is so high that it often causes poor contact with the probe, so test operators are often seen at the production line, blowing desperately with air guns, or wiping away places where they need to be tested with alcohol.
In fact, wave soldering test point will have the problem of poor contact probe. After the prevalence of SMT, the miscalculation of test was greatly improved, and the application of test points was given great responsibility. The parts of the SMT are usually too fragile to withstand the pressure of the test probe. By using the test point, it can not only protect the parts from damage, but also increase the reliability of the test. There are fewer miscarriages of justice.(pcb fast)
