With the rapid development of current electronic technology, needles are also common electronic components in the electronic market. The working principle of the pin header is to maintain signal distortion and energy loss between equipment systems through power connections and signal transmission between components and devices. For those who have just come into contact, such as the performance characteristics and operating precautions of needle and mother typesetting, they may not have a good understanding of these knowledge points. Below, the editor will explain to you the performance characteristics and operating precautions of needle and mother typesetting.

1. Easy operation and mechanical strength of needle arranging are also important factors. Connectors are usually the interfaces of PCBs for communication between motherboards and external components. Pin and pin connectors have strong load-bearing capacity and may sometimes encounter significant external forces, remaining intact.

2. The components assembled by through-hole technology have much higher reliability than the corresponding T-components. Whether it is strong pulling, squeezing or thermal shock, it can withstand and is not easy to detach from the PCB.

3. The pin and bus arrangement processing of field wiring in the industrial field is usually a high-power component, which can meet the needs of different transmission of high voltage and large current.

4. These advantages are accompanied by a decrease and weakening of the adhesion of the upper components of the PCB. The characteristics of pin and mother components are compact design, easy installation, and significant differences in size and assembly form compared to through-hole pin and mother components.

5. Electrical strength refers to the rated test voltage between the pin, contact or contact and the shell.

6. The general needle and mother wire can adapt to the attenuation caused by electromagnetic interference and have the ability to shield electromagnetic interference.

7. The contact resistance of the needle is as small as tens of milliohms.

1. The cooling design of the pin header will generate heat during operation, and excessive temperature will affect the LED. Therefore, both PCB board heat dissipation and box ventilation heat dissipation will affect the pin header.

2. Check if there are good anti-static measures for the anti-static pin and mother.

3. In the case of a small current value of 20mA for pin and busbar arrangement, it is generally recommended that the maximum current used should not exceed 80% of the nominal value, especially in electronic devices with small point spacing. Due to poor heat dissipation conditions, the current value should also be reduced.

4. Control the verticality of the board. For direct insertion of pins and sockets, there should be sufficient technology to ensure that the LED is perpendicular to the PCB board during the furnace.

5. The temperature and passing time of wave soldering should be strictly controlled. The preheating temperature is 1000 ℃± 5 ℃, with a maximum of 120 ℃. The preheating temperature should rise steadily. The welding temperature is 245 ℃± 5 ℃, and it is recommended that the welding time should not exceed 3 seconds.
