1. LED soldering conditions reflow soldering: please preheat at 150℃, within 2 minutes, and perform one soldering at 240℃ within 5s after heating. Soldering iron soldering: Use a temperature controlled soldering iron of up to 25W, the tip temperature of which is not higher than 320℃, and the soldering can be completed once within 3 seconds. Do not apply external force to the product during soldering. Do not bend the circuit board after welding.
2, LED lamp bead packaging due to the moisture absorption of the resin causes moisture evaporation and expansion during welding, which may cause interface peeling, so the purpose of moisture-proof packaging is to ensure the lowest moisture in the packaging bag. The product should be used within one year from the date of packaging. Before the packaging bag is opened, it should be stored in an environment with a temperature of 5-30°C and a relative humidity of <60%. After unsealing the packaging bag, the product must be welded and used within 24 hours, otherwise the product must be stored in an environment with a temperature of 5~30℃ and a relative humidity of <30% for no longer than a week; if there are unused products, please put them back If the product is sealed and stored in a moisture-proof bag, if the product exceeds the above storage requirements or is damp, it must be baked at 60±5°C for 12 hours. The electrode surface of the product is gold-plated, which is prone to corrosion or discoloration, which may cause welding difficulties. It is recommended to use it as soon as possible. Take care to avoid rapid changes in ambient temperature, especially in humid environments.
3. Electrostatic protection. High-brightness blue, green and white products are sensitive to static electricity. Please pay attention to the static surge that can damage or destroy the product in use. Please use a conductive pad to ground the workbench in contact with the product. The tip of the soldering iron must be grounded; an ion generator is recommended.
