3. The following illustrations show the definition of response
delay time.
Note: 1. Hysteresis denotes the difference in forward LED
current value, expressed in percentage, calculated
from the respective forward LED currents when the
photo IC in turned from ON to OFF and when the
photo IC in turned from OFF to ON.

Precautions
■ Soldering Information
Reflow soldering
• The following soldering paste is recommended:
Melting temperature: 216 to 220°C
Composition: Sn 3.5 Ag 0.75 Cu
• The recommended thickness of the metal mask for screen printing
is between 0.2 and 0.25 mm.
• Set the reflow oven so that the temperature profile shown in the following chart is obtained for the upper surface of the product being
soldered.
Temperature
1 to 5°C/s
260°C max.
255°C max.
230°C max.
1 to 5°C/s
150 to 180°C
120 sec
10 sec max.
40 sec max.
Time
Manual soldering
• Use”Sn 60” (60% tin and 40% lead) or solder with silver content.
• Use a soldering iron of less than 25 W, and keep the temperature
of the iron tip at 300°C or below.
• Solder each point for a maximum of three seconds.
• After soldering, allow the product to return to room temperature
before handling it.
Storage
To protect the product from the effects of humidity until the package
is opened, dry-box storage is recommended. If this is not possible,
store the product under the following conditions:
Temperature: 10 to 30°C
Humidity: 60% max.
The product is packed in a humidity-proof envelope. Reflow
soldering must be done within 48 hours after opening the envelope,
during which time the product must be stored under 30°C at 80%
maximum humidity.
If it is necessary to store the product after opening the envelope, use
dry-box storage or reseal the envelope.
Baking
If a product has remained packed in a humidity-proof envelope for six
months or more, or if more than 48 hours have lapsed since the
envelope was opened, bake the product under the following
conditions before use:
Reel: 60°C for 24 hours or more
Bulk: 80°C for 4 hours or more
