8. Precautions
(1) Storage conditions
Keep the product in a dry box or a desiccator with a desiccant in order to prevent moisture absorption. a. Keep it at a temperature in the range from 5C to 30C and at a humidity of less than 60% RH. In case of being stored for more than 3 months, the product should be sealed with Nitrogen gas.
(2) After opening the package
When soldering, this could result in a decrease of the photoelectric effect or light intensity. a. Soldering should be done right after mounting the product. b. Keep the temperature in the range from 5C to 40C and the humidity at less than 30%. Soldering should be done within 7 days after opening the desiccant package. If the product has been exposed for more than 7 days after opening the package or the indicating color of the desiccator changes, the product must be baked at a temperature between 60C and 65C for 10 to 12 hours. An unused and unsealed product should be repacked in a desiccant package and kept sealed in a dry atmosphere.
(3) Precautions for use
Any external mechanical force or excessive vibration should not be applied to the product during cooling after soldering, and it is preferable to avoid rapid cooling. The product should not be mounted on a distorted part of PCB. Gloves or wrist bands for ESD(Electric Static Discharge) should be wore in order to prevent ESD and surge damage, and all devices and equipments must be grounded to the earth.
(4) Miscellaneous
Radiation resistance is not considered. When cleaning the product, any kind of fluid such as water, oil and organic solvent must not be used and IPA(Isopropyl Alcohol) must be used. When using the product, operating current should be settled in consideration of the maximum ambient temperature. Its appearance or specification for improvement is subject to change without notice.
