Precautions ■ Soldering Information Reflow soldering (cid:129)The following soldering paste is recommended: Melting temperature: 216 to 220°C Composition: Sn 3.5 Ag 0.75 Cu (cid:129)The recommended thickness of the metal mask for screen printing is between 0.2 and 0.25 mm. (cid:129)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. 260°C max. 1 to 5°C/s 255°C max. 230°C max. ure 1 to 5°C/s 150 to 180°C at er p m Te 10 sec max. 120 sec 40 sec max. Time Manual soldering (cid:129)Use ”Sn 60” (60% tin and 40% lead) or solder with silver content. (cid:129)Use a soldering iron of less than 25 W, and keep the temperature of the iron tip at 300°C or below. (cid:129)Solder each point for a maximum of three seconds. (cid:129)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 EE-SX1109 Photomicrosensor (Transmissive) 73
