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.
