How do we guarantee the quality of the needle and the mother with technology? How much do you know about the arrangement of needle and mother? I will introduce to you in detail. The following is how to ensure that the quality of the needle row can be used to ensure the quality of the needle row. There are the following points:

1. anti-static pin and bus electronic display assembly factory should have good anti-static measures.

2. Heat dissipation design When the pin and bus are working, the high temperature will affect the attenuation speed and stability of LED, so the heat dissipation design of PCB board and the ventilation and heat dissipation design of box will affect the performance of LED.

3. The nominal current of the design current is 20mA. It is generally recommended that the upper limit of the current is not more than 80% of the nominal value, especially for the display with very small point spacing, due to poor heat dissipation conditions, the current value should also be reduced.

4. The temperature and time of wave soldering shall be strictly controlled. The preheating temperature is 100 ° C ±5 ° C and the upper limit is 120 ° C. The preheating temperature must rise steadily. The welding temperature should be 245 ° C ±5 ° C and the welding time should not exceed 3 seconds.

5. Control the verticality of the lamp for the straight plug pin and bus, there should be enough technology to ensure that the LED is perpendicular to the PCB board when passing the furnace.
