Pin header and female connector product quality problems

1. For example, when the electronic display assembly factory is applied to the header and female connector products, anti-static measures should be taken for the product.


2. The electronic display should control the verticality of the lamp. For in-line pin header and female connector products, there must be sufficient process technology to ensure that the LED is perpendicular to the PCB board when passing the furnace.


3. Pin header and female connector products will generate heat when working, so heat dissipation design should be done, because too high temperature will affect the attenuation speed and stability of LED, so the heat dissipation design of PCB board, ventilation and heat dissipation design of the box Will affect the performance of the LED.


4. Design current value The nominal current of the header and female header is 20mA. Generally, it is recommended that the maximum current used is not more than 80% of the nominal value. Especially for the display with small dot pitch, due to poor heat dissipation conditions, it should be Reduce the current value.


5. The temperature and time of wave soldering must be strictly controlled. The preheating temperature is 100℃±5℃, and the height does not exceed 120℃. The preheating temperature must rise smoothly. The soldering temperature is 245℃. ±5℃, the welding time is recommended not to exceed 3 seconds.
