How should we ensure the quality of the needle and busbar using technology? How much do you know about the needle and needle arrangement? The editor will provide a detailed introduction to everyone. The following is how to ensure the quality of the needle and busbar arrangement through technology. The specific points are as follows:

01. The assembly factory of the anti-static pin array electronic display screen should have good anti-static measures.

02. Heat dissipation design: When the pin and busbar work, they will generate heat. If the temperature is too high, it will affect the attenuation speed and stability of the LED. Therefore, the heat dissipation design of the PCB board and the ventilation and heat dissipation design of the box will affect the performance of the LED.

03. The nominal current for the design current value of the pin and busbar is 20mA. It is generally recommended that the upper limit of the current usage should not exceed 80% of the nominal value, especially for display screens with small point spacing. Due to poor heat dissipation conditions, the current value should also be reduced.

04. The temperature and time of wave soldering must be strictly controlled. The preheating temperature is 100 ℃± 5 ℃, with an upper limit not exceeding 120 ℃. The preheating temperature should rise steadily, and the welding temperature should be 245 ℃± 5 ℃. It is recommended that the welding time should not exceed 3 seconds.

05. To control the verticality of the lamp, for the plug-in pin and busbar, there should be sufficient process technology to ensure that the LED is perpendicular to the PCB board when passing through the furnace.
