What do I need to pay attention to when producing pin-row connectors?
In the design of electronic connectors, the row of pins is an extremely important part. Because it is often the key to the entire connector through-conductivity - contact. The stability and safety of the performance of the pin depends on the quality of the entire connector. Therefore, in the factory production should pay attention to the various considerations of the row of pins.
1. Thermal design. Pin connector will work in the heat, the temperature is too high will affect the decay rate and stability of LED, so the PCB board heat dissipation, case ventilation heat will affect the connector.
2. Check the anti-static performance. Check whether the row of pin connectors have good anti-static measures.
3. Pin connector supports a smaller current value of 20mA, it is generally recommended that its maximum use of current for not more than 80% of the nominal value, especially for point spacing is very small in electronic equipment, due to poor thermal conditions, should also reduce the current value.
4. Control the verticality of the board and pin. For direct-insert pin connectors, over the furnace to have sufficient process technology to ensure that the LED is perpendicular to the PCB board.
5. Over the wave soldering temperature and time. Must strictly control the wave front welding temperature and over the furnace time. General preheating temperature 100 ℃ ± 5 ℃, the maximum does not exceed 120 ℃, and preheating temperature rise requires a smooth, welding temperature of 245 ℃ ± 5 ℃, welding time is generally recommended that it is best not to exceed 3 seconds.
