Information

The basic performance of the pin header can be divided into three categories, namely environmental performance, electrical performance and its mechanical performance, and another important mechanical performance directly determines its mechanical life, which refers to the mechanical life of the pin header. It is a kind of durability. Among the related indicators, it is based on one insertion and one withdrawal as a cycle, and whether the pin header can normally complete its connection function in the specified cycle as a judgment basis. Next, The 2.54mm pitch pin header on sales editor will tell you what the basic performance of the pin header is like?


From the mechanical performance of the pin header, it depends on its connection ability. Its insertion and extraction force is a more important mechanical performance. The insertion and extraction force of the pin header can be divided into insertion force and extraction force. The requirements for both are It is not the same, and the insertion force and separation force regulations in the relevant standards indicate that from the perspective of use, the insertion force and separation force of the pin header should be small, if it is too small, it will affect the reliability of the framing. The insertion and extraction force of the pin header and its mechanical life are directly related to the quality of its structural contact surface and the accuracy of the arrangement size. The main electrical properties of the pin header include insulation resistance, contact resistance, and electrical strength. Connectors should have relatively stable and low contact resistance. The contact resistance of the pin headers ranges from a few milliohms to more than ten milliohms. The insulation resistance is an indicator of the insulation performance between the pin headers and the contact surface and the shell. And its magnitude ranges from hundreds of megaohms to several thousand megaohms.
The anti-electric performance of the pin header is also called its withstand voltage dielectric withstand voltage, which indicates the ability of the pin headers to withstand the rated test voltage. Other properties of the pin header include electromagnetic interference leakage attenuation. This is to evaluate a row The electromagnetic interference shielding ability of the needle, and the electromagnetic attenuation is to evaluate the anti-interference effect of the header. Generally, a simple test will be carried out in the frequency range between 100 Hz and 10 Hz. The environmental performance of the header includes humidity resistance and temperature resistance. , Vibration resistance, impact resistance, salt spray resistance and so on.
The above is the 2.54mm pitch pin header on sales editor: a brief introduction to the basic performance of the pin header.

Cheapest 2.54mm pitch pin header introduces the soldering knowledge of the header

Place the soldering iron tip on the pin header and the soldering surface, and then feed the solder wire in 1 second. Remove the solder wire first when appropriate, and then remove the soldering iron. Because the solder paste is applied in advance, the solder wire will naturally fit the welding surface after melting, making it easy to fit and weld.
