TAI-SAW TECH NOLOGY CO., LTD. 8 Notes of the Usage: 1. Touch the solder iron at 260+/-5 deg C onto the leads for 10+/-2 sec max or touch the solder at 350+/-5 deg C onto the leads for 3+/-0.5 sec. 2. In the customer’s reflow process, if it will remain s ome mechanical stress at the soldering terminals, also make some cracks on the soldering terminat ion. Some cracks will cause open or short circuit and cause of thermal increasing o r smoking. Don’t make any excess mechanical stress to soldering points. 3. In case of giving a heavy shock to the products, it may make an open or short circuit and cause of thermal increasing and smoking. To avoid heavy s hock impact applying to products is strictly required. 4. Ultrasonic cleaning should be avoided to prevent da mage to the TCXO. 5. Do Not Use Ultrasonic-Wave Soldering or Wave Solder with Package Immersed in Solder. Notes of the Storage: 1. To keep products under the condition at the room te mperature (-5~35 deg C) with normal humidity (45~75%). Absorption of moisture and dewdrop may make inferiority of characteristics and a short circuit. 2. Oxidization of terminals shall make the solderability more inferior. Dusts and corrosive gas will make a cause of the open or short circuit. Keep it in the clean place where is not in dusty and no corrosive gas. 3. Use the anti-static material to the storage package. 4. Don’t put any excess weight to the TCXO in the storag e process. 5. Don’t move the product from the cold place to the hot place in the short time, otherwise it may make some dew-drop, then a short circuit may happen in case. 6. Storage periods should be maximum 6 months under con dition of above item 1 after delivery from TST factory. 7. Once open the bag, there is possibility of electrica l characteristics deterioration due to absorption of moisture. So, please use parts within 7 days after opening the bag. 8. If you have to keep parts without using after openin g the bag, please put the drying agent in the bag, fold the bag and keep it in the place wh ere temperature and humidity are controlled (nitrogen atmosphere box etc.)
