1. Make sure that the unit is turned OFF when replacing the chip. 2. Use tweezers to prevent any damage to the chip surface. 3. Do not re-use the chips after removal. 4. Do not rub the electrode of chips. 5. Do not subject the chips to excessive stress. 6. It is recommended that a pencil-type soldering iron to be used. 7. The solder whose diameter is less than 0.5 mm is recommended. 8. Do not heat the chip more than 3 seconds. 9. Maintain temperature control under 260°C (500°F) when soldering. 5-3. Mounting 1. Place the solder thinly on the chip mounting foil. 2. Solder the chip temporarily while holding the chip with the tweezers.
