Pin Header and female connector is a very common electronic product at present. This article explains some knowledge related to the quality factors of pin header and female connector. The following are 5 methods to ensure the quality factor of pin header and female connector.
During the heat dissipation design, the operation of the pin header and female connector 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 LED products.
Design current value The nominal current of the pin header and female connector is 20mA. Generally, it is recommended that the maximum use current should not exceed 80% of the nominal value, especially for the display screen with small dot spacing, due to poor heat dissipation conditions, also The current value should be reduced.
When performing anti-static operations, the assembly manufacturer using the pin header and female connector should have good anti-static measures to avoid risks.
Pay attention to control the verticality of the lamp, because for the in-line pin header and female connector, there must be enough process technology to ensure that the LED product is vertical to the PCB board when passing through the furnace.
It should be noted that the temperature and time of wave soldering must be strictly controlled for the pin header and female connector. The preheating temperature is 100°C±5°C, the maximum is not more than 120°C, and the preheating temperature is required to rise steadily. The welding temperature is 245°C±5°C, and the welding time is recommended not to exceed 3 seconds.
