How can we guarantee the quality of needle and busbar with technology? How much do you know about row needle and row mother? Today, the editor of Cixi Lanling Electronics will give you a detailed introduction. The following is how to ensure the quality of the needle and busbar by using technology. The specific points are as follows:

1. The assembly factory of anti-static pin and bus electronic display screen shall have good anti-static measures.

2. Heat dissipation design: when the pin and busbar are working, they will generate heat. Too high temperature will affect the attenuation speed and stability of the LED. Therefore, the heat dissipation design of the PCB and the ventilation and heat dissipation design of the box will affect the performance of the LED.

3. The nominal current of the design current value pin and busbar is 20mA. Generally, it is recommended that the maximum current used should not exceed 80% of the nominal value. Especially for the display screen with small point spacing, the current value should be reduced due to poor heat dissipation conditions.

4. The temperature and time of wave front welding shall be strictly controlled. The preheating temperature shall be 100 ℃± 5 ℃, the maximum temperature shall not exceed 120 ℃, and the preheating temperature shall rise steadily. The welding temperature shall be 245 ℃± 5 ℃, and the welding time is recommended not to exceed 3 seconds.

5. Control the verticality of the lamp. For the in-line pin and busbar, there should be enough technology to ensure that the LED is perpendicular to the PCB when passing through the furnace.

The above five points are the methods to analyze how to ensure the quality of needle and busbar arrangement from a technical point of view. They are only for your reference!
