Use within 7 days after opening of sealed vapor/ESD barrier bags. If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage time, baking treatment should be performed using the following conditions. Baking treatment : 60±5℃ for 24 hours. Fold the opened bag firmly and keep in dry environment.
