During the heat dissipation design, the operation of Pin Header and Female Header Connectors will generate heat, and 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 products.
The nominal current of the designed current values of PIN Header and Female Header Connectors is 20mA, and it is generally recommended that the maximum current 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.
When anti-static operations are needed, the assembly manufacturers using pin header and female header connectors should have good anti-static measures to avoid risks.
Pay attention to control the verticality of the lamp, because for in-line pin header and female header connectors, there must be enough technology to ensure that LED
products are perpendicular to the PCB when passing through the furnace.
Attention should be paid to the temperature and time of pin header and female header connectors during wave soldering, and the temperature and time of wave soldering should be strictly controlled. The preheating temperature is 100℃ 5℃, and the maximum is not more than 120℃, and the preheating temperature should rise steadily. The welding temperature is 245℃ 5℃, and the welding time is recommended not to exceed 3 seconds.
