xingLight takes you to know the precautions for patch LED welding

For SMD LED products in use, please follow the following usage methods to protect SMD LED products.

1. Welding and manual welding

a. The soldering iron used must be less than 25W, the temperature of the soldering iron must be kept below 315 ℃, and the welding time cannot exceed 2s.

b. The soldering iron shall not touch the epoxy resin.

c. After welding, let it cool down to a temperature lower than 40 ℃ before packaging.

2. Moisture proof packaging To avoid moisture absorption during transportation and storage, SMD LED is packaged in a moisture proof aluminum packaging bag, which contains desiccant and humidity card. The desiccant mainly controls the humidity in the packaging bag, and the humidity card mainly monitors the humidity in the packaging bag.

3. Do not use unknown chemical liquid to clean SMD LED: unknown chemical liquid may damage SMD LED. When cleaning is necessary, immerse the SMD LED in alcohol, dry it for 15 minutes at normal room temperature for less than 1 minute, and then start to use.

4. Storage

A. The sealed packaging bag shall be stored under the conditions of temperature<40 ℃, humidity<90% RH and shelf life of 12 months. When the shelf life is exceeded, it needs to be baked again.

b. Before opening the package, please check the bag for air leakage. If there is air leakage, please bake it again before use.

c. After opening, please use it under the following conditions: temperature<30 ℃, humidity below 60% RH; If the use time exceeds 24 hours, the following baking treatment must be done before use.

d. Baking conditions: the temperature of the product in the oven is 70 ℃± 5 ℃; Relative humidity ≤ 10% RH, time: 24 hours.

e. Take out the product from the packaging bag and bake it. Do not open the oven door during baking.
