How to ensure the service life of the pin header?

In the current pcb board, the pin header is widely used, and the quality problem of the pin pin/female should be guaranteed by technology. How much do you know about the pin headers? The pin/female manufacturers will give you detailed instructions on how to ensure the quality of the pin headers. The specific points are as follows:

The pin/female header electronic display assembly factory should have good anti-static measures.

2、heat dissipation design
The pin headers will generate heat when working. If the temperature is too high, the attenuation speed and stability will be affected. Therefore, the heat dissipation design of the PCB board will affect the performance of the pin headers.

3、design current value
The rated current of the pin header is 20 mA. It is generally recommended that the maximum current used is not more than 80% of the rated value.

4、over wave soldering temperature and time
The temperature of the wave front welding and the furnace time must be strictly controlled. The preheating temperature is 100 °C ± 5 °C, the maximum is not more than 120 °C, and the preheating temperature rise is required to be stable, the welding temperature is 245 °C ± 5 °C, and the welding time is recommended not to exceed 3 seconds. 

5、control the verticality of the lamp
For the in-line type of pin header, there must be enough process technology to ensure that it is perpendicular to the PCB.
