Product performance description
产品性能介绍说明
The test probe is mainly composed of a spring, a needle tube and a needle. It is an important part of PCB test or semiconductor test. The mechanical and electrical properties of the test probe are the two major indicators that determine the quality of the probe.
Details Images
The test probe is a high-end precision electronic hardware component. Its function is the contact medium for electrical testing.
First, the needle tube: mainly copper-plated on the outside of copper alloy
The second is spring: mainly gold-plated outside the piano steel wire and spring steel
The third is the needle: mainly tool steel (SK) nickel-plated or gold-plated
Product Usage
Product usage introduction
First, test the mechanical properties of the probe. The mechanical properties of the test probe mainly refer to the spring force of the spring. The normal range of the spring force is 10% above and below the marked spring force, such as 1N spring force. The probe may be 0.9N. If the tolerance range is too large, it may Damage to the PCB or poor contact makes the contact resistance abnormal.
Description of product use effect
Second, test the electrical properties of the probe. The contact impedance mentioned above is a very important point. Theoretically, the smaller the impedance, the better. However, since a zero-resistance material cannot occur in nature, the contact impedance should be stable during the test. Usually it is related to impedance The main factors are the following:
