The probe isThe contact medium for electrical testing is high-end precision electronic hardware components. It mainly consists of three parts: spring, needle tube, and needle tip. Also known as "spring needle", from its name, spring needle is definitely related to spring, but it is not a needle made of spring in literal meaning. This is wrong, it only has a spring structure inside, which is very different from spring. It is a very precise needleElectronic hardware componentsIt has a powerful function and a wide range of applications, such as in medical, aerospace, chip, semiconductor, mobile phone and other fields. Today, we will focus on the topic of "the shorter the length of the probe, the better" that people say!
Why do some people say that the shorter the length of the probe, the betterThe greater the degree of bending or deflection of the probe, the less accurate the measurement results of the workpiece will be. Therefore, for some precision workpieces, it is recommended to choose shorter probes to maximize the probe's deflection. This can effectively reduce false triggering caused by shaking, minimize the impact on accuracy, and make the results more accurateThe fewer connection points of the probe, the better.Even if you connect the probe and extension rod together, it is an unconscious introduction of new bending and deformation points. It is disadvantageous for measurement, therefore, it is necessary to choose as few connections as possible.Of course, when it comes to the length of the probe to be used, it is necessary to have a certain understanding of the basic knowledge of the probe and choose the appropriate size according to one's own situation.
