For example, how does the most commonly used needle row -and -row connectors in the electronics industry, as a manufacturer to ensure the quality problem of Fan Shell Mould Supply? Among them, what kind of technology needs to be involved in the production row needle rowinger connector to ensure the guarantee of the quality of the product. It mainly explains some technical issues involved in the application of the rowed pupils.
1. The nominal current of the design current value is 20mA. It is generally recommended that the maximum use current is not more than 80%of the nominal value. Especially for display screens with small spacing. Reduce the current value.
2. Electronic display to control the verticality of the lights. For the direct -inserted row -needle rowing parent connector product, there must be sufficient process technology to ensure that the LED is vertically vertically on the PCB board.
3. For example, when the electronic display screen is applied to the product of the rowing needle, the product should be taken good anti -static measures.
4. The exclusive needle and the parent connector product will generate heat when working, so the heat dissipation design should be done. Because the temperature is too high, it will affect the attenuation and stability of the LED. Therefore, the cooling design of the PCB board and the ventilation and heat dissipation design of the boxter All affect the performance of LEDs.
5. The temperature and time of overlaid welding must be strictly controlled and the temperature of the wave welding and the furnace time must be strictly controlled. The preheating temperature is 100 ° C ± 5 ° C, the maximum does not exceed 120 ° C, and the preheating temperature increases is stable, and the welding temperature is 245 ° C. ± 5 ° C, the welding time is recommended to not exceed 3 seconds.
