9. Precaution for use
• Storage
To avoid the moisture penetration, we recommend storing Z Power LEDs in a dry box
(or desiccator) with a desiccant . The recommended storage conditions are Temperature 5 to 30
degrees Centigrade. Humidity 50% maximum.
• Precaution after opening packaging
However LED is correspond SMD, when LED be soldered dip, interfacial separation may affect
the light transmission efficiency, causing the light intensity to drop.
Attention in followed.
a. Soldering should be done right after opening the package (within 24Hrs).
b. Keeping of a fraction
- Sealing
- Temperature : 5 ~ 40℃ Humidity : less than 30%
c. If the package has been opened more than 1week or the color of desiccant changes,
components should be dried for 10-12hr at 60±5℃
• Any mechanical force or any excess vibration shall not be accepted to apply during cooling
process to normal temp. after soldering.
• Please avoid rapid cooling after soldering.
• Components should not be mounted on warped direction of PCB.
• Anti radioactive ray design is not considered for the products listed here in.
• Gallium arsenide is used in some of the products listed in this publication. These products are
dangerous if they are burned or shredded in the process of disposal. It is also dangerous to
drink the liquid or inhale the gas generated by such products when chemically disposed.
• This device should not be used in any type of fluid such as water, oil, organic solvent and etc.
When washing is required, IPA(Isopropyl Alcohol) should be used.
• When the LEDs are illuminating, operating current should be decided after considering the
package maximum temperature.
• LEDs must be stored to maintain a clean atmosphere. If the LEDs are stored for 3 months or
more after being shipped from SSC, a sealed container with a nitrogen atmosphere should be used for storage.
• The appearance and specifications of the product may be modified for improvement without
notice.
• Long time exposure of sunlight or occasional UV exposure will cause lens discoloration.
• The slug is connected to the anode. Therefore, we recommend to isolate the heat sink.
• Attaching LEDs, don’t use adhesives to generate organic vapor.
