The characteristic change or the product might be damaged by the handling method of mounting.
Please note the following and handle the product.
(*)The product is evaluated using above reflow soldering conditions. No additional test is performed
exceed the condition (i.e. the condition more than MAX values) as an evaluation.
Please perform reflow soldering under the above conditions. Perform reflow soldering no more than
twice.
is turned on it takes at least 20 ms for the internal circuit to stabilize. During this time the output
To avoid moisture absorption by the resin, the product is packed in an aluminum envelope with silica
gel.
Since the optical characteristics of the device can be affected during soldering by vaporization
resulting from prior absorption of moisture and they should therefore be stored under the following
conditions:
Baking in taping with reel is required if the devices have been store unopened for more than six
months or if the aluminum envelope has been opened for more than 168 h.
These devices are packed on tapes; hence, please avoid baking at high temperature.
Do not apply stress to the resin at high temperature.
The resin part is easily scratched, so avoid friction with hard materials.
When installing the assembly board in equipment, ensure that this product does not come into
contact with other components.
Please confirm the heat contraction of the substrate of the reflow mounting doesn't influence the
product. The load is given to the product by mounting that the heat contraction is large on the
substrate and the installation position of the substrate. Please note that the characteristic changes
or the product might be damaged.
Example of reflow soldering
•
Temperature: 5°C to 30°C, Relative humidity: 70% (max), Time: 168 h (max)
Time until the product returns at the normal temperature after mounting of
the reflow is different according to the mounting substrate and the environment.
Please do not give the stress with heat remained in the product.
Please perform the first reflow soldering within 168 h after opening the package with reference to
the above temperature profile.
Recommended baking conditions: 60°C for 12 h or longer, Perform baking only once
