Test Procedures
The Sanyo evaluation board must be used for the following tests.
1. Sensitivity Use a CCV31F pattern box (manufactured by Dai Nippon Printing Co., Ltd.) set up at a brightness of 1500 NT and color temperature of 5100°K with no pattern. Image the pattern box with an HF16A lens (manufactured by Fujinon) with a 1 mm thick C-500 IR cut filter in front of that lens. Set the lens f-stop to f8 and set the lens to be 50 cm from the pattern box. Measure the CCD output signal from the center of the image with this setup.
2. Uniformity of Output Signal Measure under the following conditions.
• Standard drive conditions (See the specifications document.)
• Use a 3200°K color temperature halogen lamp as the light source.
• Use a 1 mm thick C-500 IR cut filter.
Set the CCD surface illumination to 7 lux, and divide the image into 45 areas as shown in Figure 4. Measure the average value for each block, and determine the maximum, minimum, and mean of those values. Determine the ratio of the range of the block average values to the mean of the block average values.
VF =

3. Saturated Signal Saturate the output signal by removing the lens in the test setup for item 1. Measure the CCD output signal from the center of the image in this state.

4. Smear
• Place a 1/10 V chart in front of the halogen light source as shown in the figure and image that chart.
• Adjust the amount of light entering the CCD with ND filters so that the CCD output signal at point A becomes 250 mV.
• Remove the ND filter(s) and measure the output value of the CCD output signal from the first line (point B).

VB: The amount of smear at point B [mV] TND: The ND filter transmissivity

5. Dark Signal Completely block all light from falling on the CCD element surface and measure the CCD output signal at the center of the image. Here, do not measure the difference between this signal and the optical black section level, but rather measure the difference between this signal and the no signal level that has no pixel information. (See Figure 6.)

6. Color Uniformity Use a CCV31F pattern box (manufactured by Dai Nippon Printing Co., Ltd.) set up at a brightness of 1500 NT and color temperature of 5100°K with no pattern. Use the Sanyo LC9997-LE01 lens and a C-500 IR cut filter. Adjust the exposure with ND filters so that the CCD output signal level is 500 mV. Measure the chrominance signal level and chrominance signal phase at 16 points in the image as shown in Figure 7. Calculate the color unevenness, VCS(mV), from these chrominance signal level and phase values.

Notes on Mounting and Handling
1. Preventing Electrostatic Discharge (ESD) Since CCD sensors are easily destroyed by ESD, the antistatic measures described below should be employed when handling this device.
• All tools and personnel must be grounded when handling CCDs. Note that a 1 Mresistor should be inserted in
series between personnel and ground for safety. (We recommend using wrist straps for personnel grounding.)
• Personnel should handle CCD devices with either bare hands or antistatic gloves. Use antistatic materials for work
garments. Personnel should wear conductive shoes.
• Lay conductive mats on the floor and benches in the workplace so that static charges do not accumulate.
• We recommend using ionized air blowers (or other static removal techniques) when handling CCD sensors.
• Use antistatic boxes when transporting boards that have CCD sensors mounted on them.
• Do not leave packing materials or fittings made from plastic materials (such as Styrofoam) that easily collect static
charges on or near workplace tables.
• Ground all tools, test equipment, conveyors, soldering irons, and other objects used in the workplace. Inspect
grounding regularly to assure that it is complete.
• Do not handle this IC in the vicinity of TV monitors or other equipment that generates high static voltages. If
unavoidable, install antistatic filters in front of monitor screens and take all other possible antistatic measures.
• Static charges accumulate easily in workplaces with a low relative humidity. Manufacturing operations should be
carried out in an environment with a relative humidity of at least 50%.
2. Soldering
• The CCD package temperature must not exceed 80°C.
• Since CCD sensors are sensitive to thermal stress as well as ESD, the soldering iron temperature should be under
300°C. Aim for a soldering time of 2 seconds per pin.
• Use soldering irons that include an adjustable temperature control function that holds the soldering iron tip at a
constant temperature.
• Be especially careful to assure that the device package temperature does not exceed 80°C when repairing or
redoing solder joints or when removing CCD sensors from printed circuit boards.
3. Soiling and Contamination Prevention
• CCD sensors should be handled in a clean workplace. (A class 1000 level is appropriate.)
• Do not touch the package surface and do not allow any object to contact the package surface. Use compressed air
to remove any foreign objects (such as dust) that land on the package surface. (We recommend using an ionized air blower if possible.)
• Use a cotton swab dipped in ethyl alcohol to remove oily contamination, being especially careful not to scratch the
package surface.
• Use special-purpose cases to prevent soiling and contamination. Warm or cool CCD sensors in advance to prevent
condensation when transporting between rooms with radically differing temperatures.
• For CCD sensors that are shipped with protective tape applied, only remove that tape immediately prior to use in
an environment in which ESD prevention measures have been fully implemented. Do not reuse protective tape that has been removed from a CCD sensor.

4. Storage
• Do not allow sunlight or other bright light to fall on CCD sensors for extended periods.
• Since harsh conditions such as high temperatures or high humidities can adversely influence device characteristics,
do not use or store these devices in environments with such conditions. Samples should be stored in places where the temperature and humidity fall in normal ranges, i.e., 5 to 35°C and 45 to 75% RH.
• Since CCD sensors are precision optical components, they should not be subjected to mechanical shocks.
• Avoid locations with corrosive atmospheres or high dust levels.
• Avoid locations subject to rapid temperature changes.
• Do not place heavy objects on top of boxes containing CCD sensors during storage.
• Use materials that cannot accumulate static charges for containers used to hold samples.
• Do not subject magazines holding CCD sensors to mechanical shocks, since this could adversely influence
reliability during mounting due to pin bending and other problems.
5. Notes on Mounting
• Flare can occur if a lens with an optical size larger than 1/5" is used. Consult your Sanyo sales representative in
advance when selecting lenses.
• This product is mounted in a fully transparent plastic package, and is easily influenced by light that passes through
the mounting board from the back to the front. Design end-products to adequately block out extraneous light.
6. Shipping
• Do not drop or throw packages containing CCD sensors.
• Do not allow packages containing CCD sensors to become wet due to rain or snow.
• Protect packages containing CCD sensors from mechanical shock and vibration as much as possible during
shipping.
