EE-SX1108 Photomicrosensor (Transmissive) 35
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.
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
260°C max.
