LED Lamp Beads Are Often Welded

Directly inserted LED lamp beads in the process of welding, please strictly abide by the following requirements: 1. Be sure to wear anti -static gloves, anti -static wrists, etc. during actual production. Only lead. Because the humidity of the human body on the workbench is 60%-90%, the static electricity of the human body will damage the crystal layer of the LED lamp beads. After a period of time, the LED lamp beads will show failure and dead lamps. 2. Welding temperature is 260 C, 3 seconds. Too high temperature and too long will burn bad chips. In order to better protect the LED lamp beads, LED lamp beads and PC boards should be kept at a distance of more than 2mm to make the welding heat dispel. 3. The normal operating current of the direct -inserted LED lamp bead is 20mA, and the micro fluctuations of the voltage will cause a large fluctuation of the current. Therefore, during the design of the circuit design, different current -limiting resistors should be paid according to the voltage and deployment of LED lamp beads to ensure that the LED lamp beads are in the best working state. When the current is too large, the LED lamp beads will shorten the life, the current is too small, and the required brightness requirements cannot be met. Our company will split the LED lamp beads when batch supply, that is, the LED lamp bead parameters in the same pack of products are consistent, ensuring the consistency of the actual product. At present, the more common LED lamp beads welding method: 1. Single iron welding: the tip of the tip of the soldering iron does not exceed 300 C, the welding time does not exceed 3 seconds, and the welding position is at least 2mm from the colloid. 2. Summit welding: The maximum temperature of soaking welding is 260 C, the welding time does not exceed 5 seconds, and the soaked welding position is at least 2mm from the colloid. Directly inserted LED lamp bead welding curve pins method: 1. Must be 2mm from the collagen to bend the bracket. 2. The formation of the bracket needs to ensure the pins and spacing consistent with the line board. 3. The formation of the bracket must be done with a fixture or by a professionals. 4. The formation of the bracket must be completed before welding.
