1. The LED lamp beads are installed by tin welding.
2. In-line plug-in plug-in lamp beads are generally used for wave soldering and soldering iron welding.
3. SMD led lamp beads to reflow welding, but pay attention to control reflow welding temperature during welding, not more than 260 degrees, and welding time does not exceed 3-5 seconds.
4. Before installation, check whether the light emitting color, brightness and color temperature of the lamp beads are consistent with the requirements, as well as whether the surface of the lamp beads is scratched, whether the soldering pins are bright, and whether there is oxidation.
