1、 LED bead products are packaged in moisture-proof and anti-static aluminum foil bags. During transportation, it is important to avoid squeezing or puncturing the packaging bags, which may cause air leakage in the moisture-proof bags;

2、 In humid seasons, when the aluminum foil moisture-proof bag is not opened, it is recommended to store it under the following conditions: temperature<30 ℃, humidity<60% RH (preferably stored in a moisture-proof cabinet) and use it up within 6 months;

3、 If the LED beads have not been used up within 6 months, it is recommended to add an oven for drying and dehumidification before reuse (recommended dehumidification conditions are 60 ℃/24H);

4、 After unpacking, the unused LED beads should be vacuum sealed again and placed in a moisture-proof cabinet. It is prohibited to use transparent tape, staplers, etc. for simple sealing;

5、 Before using LED beads, it is necessary to check if the moisture proof beads on the humidity card have changed color. If the moisture-proof bead changes color by more than 30% or more, add an oven to bake and dehumidify before use (recommended dehumidification conditions: 60 ℃/24H)

6、 When the LED beads are unpacked and subjected to SMT, they are already exposed to the workshop environment. It is recommended to control the workshop environment: temperature<30 ℃, humidity within 60% RH;

7、 In humid seasons, it is recommended to place the lamp panels in the workshop environment for 3-5 days after Reflow (before assembling the lamps).
