３．Others

３－１．Surrounding Gas

Notice that if it is stored under the condition of acid gas (chlorine gas, sulfured gas) or

alkali gas (ammonia), it may result in low soldering ability (caused by the change in quality of

the plating surface ) or optical characteristics changes (light intensity, chrominance) and change

in quality of cause die bonding (Ag-paste) materials. All of the above will function failure of

Therefore, please pay attention to the storage environment for mounted product (concern the

３－２．Electrostatic Damage

The product is part of semiconductor and electrostatic sensitive, there’s high possibility to be damaged

by the electrostatic discharge. Please take appropriate measures to avoid the static electricity from

human body and earthing of production equipment. Especially, InGaN type LEDs have lower resistance

value of electrostatic discharge and it is recommended to introduce the ESD protection circuit.

The resistance values of electrostatic discharge (actual values) vary with products, therefore,

please call our Sales staffs for inquiries.

３－３． Electromagnetic Wave

Applications with strong electromagnetic wave such as, IH cooker, will influence the reliability of LED,

therefore please evaluate before using it.

so please pay attention to the touch on product.

We recommend the soldering pattern that shows on the right.

It will be different according to mounting situation of circuit board,

therefore, please concern before designing.

※The product has adopted the electrode structure that it should solder

with back electrode of the product.

Thus, please be informed that the shape of electrode pin of

solder fillet formation is not guaranteed.

The through hole on electrode surface is for conduction of front

　and rear electrodes but not for formation of solder ﬁllet.

４―４. Mechanical Stress after Mounting

The mechanical stress may damage the LED after Circuit Mounting,

４－５．Soldering Pattern for Recommendation

・set ionizer to prevent electrostatic charge

４－３. Mounting Location

The stress like bending stress of circuit board dividing after mounting, may cause LED package crack

or damage of LED internal junction, therefore, please concern the mounting direction and position

to avoid bending or screwing with great stress of the circuit board.

expansion and moisture absorption at humidity will cause heat stress during soldering process and

finally has bad influence on the product’s reliability.

・The product is not guaranteed for ﬂow soldering.

・Do not expose the product in the environment of high temperature (over 100℃) or rapid temperature

shift (within 3℃/sec. of temperature gradient) during the flow soldering of surrounding parts.

・Please set appropriate reﬂow temperature based on our product usage conditions and speciﬁcation.

・The max for reﬂowing is 2 times, please ﬁnish the second reﬂow soldering and ﬂow soldering

with other parts within the usage limitation after open the moistureproof package.

・Compare with N2 reﬂow, during air reﬂow, because of the heat and surrounding conditions,

it may cause the discoloration of the resin.

・No resin hardening agent such as ﬁller is used in the sealing resin of the product. Therefore, resin

In case of carrying out flow soldering of surrounding parts without recommended conditions, please

４－２. Automatic Mounting

Vibration may result in low mounting rate since it will cause the static electricity of product and
