Pin headers and female headers are often used in electronic products, how should we ensure the quality and application of technical? How much do you understand about formal applications? The following description is to explain how to ensure the quality of pin headers and female connectors during using.
Below details for your reference:
1. Assembly factory that use pin headers and female connectors should have good anti-static measures.
2. During wave soldering, it is necessary to strictly control the temperature and time of wave soldering. The preheating temperature is 100°C±5°C, and the maximum temperature should not exceed 120°C, and the preheating temperature should rise steadily. The soldering temperature is 245°C±5°C, and the soldering time is recommended not to exceed 3 seconds.
3. In terms of heat dissipation design, the pin header and female connector will generate heat when used, and excessive temperature will affect the attenuation speed and stability of LED. Therefore, the heat dissipation design of PCB board and the ventilation and heat dissipation design of the box will affect the LED performance.
4. In the design current value, the nominal current of the pin and female connector is 20mA, and it is generally recommended that the maximum operating current should not exceed 80% of the nominal value. Especially for displays with small dot spacing, due to poor heat dissipation conditions , should also reduce the current value.
