21 / 24 page ![]() Data Sheet S15418EJ2V0DS 21 µµµµ PD3768 NOTES ON HANDLING THE PACKAGES OPERATE AND STORAGE ENVIRONMENTS 3 Operate in clean environments. CCD image sensors are precise optical equipment that should not be subject to mechanical shocks. Exposure to high temperatures or humidity will affect the characteristics. So avoid storage or usage in such conditions. Keep in a case to protect from dust and dirt. Dew condensation may occur on CCD image sensors when the devices are transported from a low-temperature environment to a high-temperature environment. Avoid such rapid temperature changes. For more details, refer to our document "Review of Quality and Reliability Handbook" (C12769E) ELECTROSTATIC BREAKDOWN CCD image sensor is protected against static electricity, but destruction due to static electricity is sometimes detected. Before handling be sure to take the following protective measures. 1. Ground the tools such as soldering iron, radio cutting pliers of or pincer. 2. Install a conductive mat or on the floor or working table to prevent the generation of static electricity. 3. Either handle bare handed or use non-chargeable gloves, clothes or material. 4. Ionized air is recommended for discharge when handling CCD image sensor. 5. For the shipment of mounted substrates, use box treated for prevention of static charges. 6. Anyone who is handling CCD image sensors, mounting them on PCBs or testing or inspecting PCBs on which CCD image sensors have been mounted must wear anti-static bands such as wrist straps and ankle straps which are grounded via a series resistance connection of about 1 M Ω. 4 |
