8. Packing Specifications
8-1. Moisture-proof Packing
To prevent moisture absorption during transportation and storage, reels are packed in
aluminum envelopes which contain a desiccant with a humidity indicator.
Aluminum envelop

Desiccant
Polyester Zip fastener
Label
8-2. Storage
To prevent moisture absorption, it is strongly recommended that reels (in bulk or taped)
should be stored in the dry box (or the desiccator) with a desiccant as the appropriate
storage place. If not, the following is recommended.
Temperature:
Humidity:
5 ~ 30 °C
60%RH max.
The devices should be mounted as soon as possible after unpacking. If you store the
unpacked reels, please store them in the dry box or seal them into the envelop again.
8-3. Baking
If the devices have been stored over 6 months or unpacked over 7days, it should be baked
under the following conditions.
Baking conditions:
60°C ´ 12 hours or more (reeled one)
100°C ´ 45 minutes or more (loose one)
150°C ´ 15 minutes or more (loose one)

9. Precautions
9-1. Soldering
(1) Manual soldering
1) Use 6/4 solder or solder containing silver (Ag)
2) Before soldering every time, make baking to units. By manual soldering, it is the
possibility of crack due to the moisture absorption in the resin portion.
3) Use a soldering iron of 25W or smaller. Adjust the temperature of the soldering
iron below 300°C.
4) Force or stress must not be applied to the resin portion while soldering.
5) Finish soldering within 3 seconds.
6) Handle the devices only after temperature is cooled down.
(2) Reflow soldering
1) The temperature profile at the top surface of the parts is recommended as shown
below.
2) It is requested that products should be handled after their temperature has dropped
down to the normal room temperature.
Temperature
4℃／sec.Max.
230℃ Max.
4℃／sec.Max.
220℃ Max.
150～170℃

Time
9-2. Handling
(1) It is requested to avoid any stress added to the lens portion.
(2) It is requested to avoid any friction by sharp metal nail etc. to the lens portion.
(3) Please be aware that this product should not come into contact with any other parts
in assembled status.
(4) - Please take measures to prevent any static electricity being produced such as
the wearing of a wristband or anti-static gloves when handling this product.
- As for damages due to static electricity, please check them by lighting inspection.
9-3. Other
(1) This product complies with RoHs directives.
(2) This product is intended for the application in general electronic devices (such as
office automation equipment, communication devices, audio-video equipment,
home electrical appliances, measurementhardware and others).
In cases where this product is used for the applications that requires high
reliability or could directly affect human life or health due to failure or malfunction
(aerospace hardware, medical equipment, atomic control equipment and others),
please consult with our sales representatives beforehand.
(3) Our warranty does not cover situations where this product undergoes secondary
fabrication such as changes in shape.
(4) An agreement of formal product specifications is required prior to mass production.
(5) The specifications and appearance of this product are subject to change without advanced
notice.

10. Designing precautions
(1) Drive circuit
- A constant current circuit is recommended as a drive circuit.
And when two or more LED packages are connected, the series connection
between each package is recommended.
- Please design a circuit that prevents any reverse voltage (excess current) from being
applied to this product instentaneously when the circuit is ON or OFF.
(2) Recommended soldering pattern
<For reflow soldering>
Unit : mm
* The dimensions are common to four patterns.
The above dimensions are not the one which guarantee the performance of mountability.
The use of the above pattern is recommended to use after deep study at your site.
(3) When assembling the circuit board into the finished products, care must be taken to avoid
the component parts from touching other parts.
(4) Thermal design
- As the LED package itself does not have any effective heat release feature, an outer heat
sink shall be connected to the package’s heat sink prior to usage as shown in the figure
below for proper heat dissipation. It is recommended that attachment material such as
heat radiating grease, heat transfer gel sheet and others is used between the package’s
heat sink and outer heat sink to increase adhesion.
- Please ensure that heat generation is not in excess of the absolute maximum rating.
- Factors responsible for an increase in temperature include heat generation attributed to
ambient temperature conditions or power dissipation. Thus, drive conditions should be
taken into consideration, depending on ambient temperature (Ta).
