Notes on Handling and Mounting
1. Static discharge prevention
The following measure for static discharge prevention must be taken, since the sensor is easily destroyed by static
discharges.
• Personnel and all equipment must be grounded when handling the sensor. For safety, personnel should be
grounded through a resistor of about 1 MΩ. (The use of wrist straps is recommended.)
• Work should be performed either with bare hands or antistatic gloves. Antistatic work uniforms should be used.
Also, conductive shoes should be worn.
• Spread conductive mats on the work place floors and on workbenches so that static charges do not arise.
• We recommend using an ionized air blower to remove static charges when handling CCD sensors.
• Use antistatic processed boxes to transport printed circuit boards with mounted CCD devices.
• Packing materials, parts, or other objects made from styrofoam or other material that easily accumulate static
electricity must not be placed on or near workbenches.
• All test equipment, conveyors, soldering irons, and other tools used in this work must be grounded. Also, this
grounding must be a perfect ground and must be checked periodically.
• Do not handle this IC in the vicinity of TV monitors or other equipment that generates high static voltages. If
operations in the vicinity of such equipment is unavoidable, anti-static measures must be taken. For example, for
TV monitors, the whole screen must be covered by an antistatic filter.
• The relative humidity in the workplace where this IC is handled must be maintained at 50%. This is because static
electricity is more easily accumulated in low humidity.
2. Soldering
• The package temperature must never exceed 80°C.
• In addition to static discharges, CCD sensors are also easily destroyed by thermal stress. The soldering iron tip
temperature should be under 300°C when mounting on a printed circuit board, and 2 seconds per pin should be set
as the target soldering time.
• Only use soldering irons that have a temperature controller that holds the soldering iron tip at a fixed temperature.
• Use extra care to avoid heating the element to over 80°C when re-soldering or removing a CCD element.
3. Dirt and contamination
• Work should be performed in a clean environment.
• Do not touch the package surface or allow any objects to contact the surface. If dirt or other contamination gets on
the package surface remove it with an air blower. (We recommend the use of an ionized air blower if possible.)
• Oily or greasy contamination can be removed with a cotton swab dipped in ethyl alcohol. Be extremely careful not
to scratch the package surface.
• Store CCD devices in their special-purpose cases to avoid dirt and other contamination and to prevent
condensation when transporting into a room with a radically differing temperature, warm or cool the device in
advance.
4. Storage methods
• Do not subject CCD products to intense light for extended periods.
• Since severe high temperature/high humidity conditions can adversely influence device characteristics, avoid
storing CCD products in such environments. The temperature and humidity in locations where samples are stored
must be within normal ranges, namely 5 to35 °C and 45 to 75%RH.
• Since CCD sensors are high precision optical components, they must be protected from mechanical shocks.
• Avoid locations where corrosive gases may be released and avoid locations with high levels of dust and dirt.
• Avoid locations subject to rapid temperature changes.
• Do not allow heavy objects to be stacked on top of the device storage containers during storage.
• Use materials that do not accumulate static charges for the containers used to hold samples.
• Since pin bending and other problems that can adversely influence reliability during mounting may occur if
mechanical shocks are applied to magazines, use care when handling magazines.
