Caution
1. Electrostatic Breakdown
Store in shorting clip or in conductive foam to avoid electrostatic breakdown.
CCD Image Sensor is protected against static electricity, but inferior puncture mode device due to static
electricity is sometimes detected. In handing the device, it is necessary to execute the following static
electricity preventive measures, in order to prevent the trouble rate increase of the manufacturing system
due to static electricity.
a. Prevent the generation of static electricity due to friction by making the work with bare hands or by
putting on cotton gloves and non-charging working clothes.
b. Discharge the static electricity by providing earth plate or earth wire on the floor, door or stand of the
work room.
c.
Ground the tools such as soldering iron, radio cutting pliers of or pincer.
It is not necessarily required to execute all precaution items for static electricity.
It is all right to mitigate the precautions by confirming that the trouble rate within the prescribed
range.
d. Ionized air is recommended for discharge when handling CCD image sensors.
2. Incident Light
CCD sensor is sensitive to infrared light. Note that infrared light component degrades resolution and
PRNU of CCD sensor.
3. Moisture-proof Packing
CCD surface mount products may have a haze on the inside of glass when thermal stress is applied
during surface mount assembly after they absorb atmospheric moisture. However, since a haze will
disappear if time passes even if a haze happens on the inside of glass, there is no problem in quality, If you
are worrisome such a haze, please observe the following precautions:
a.
This moisture barrier bag may be stored unopened 12 months at or below 30°C/90% RH.
b.
After opening this moisture proof bag, the packages should be assembled within 5 days in an
environment less than 30°C/60% RH.
c.
If upon opening, the moisture indicator card shows humidity above 30% or the expiration date has
passed, they may still be used with the addition of a bake of 3 hours at 125°C. After baking the
packages, it should be assembled with 5 days in an environment less than 30°C/60% RH.
d.
Expiration date; 12 months from sealing date, which is imprinted near the heat-seal.
4. Ultrasonic Cleaning
Ultrasonic cleaning should not be used with such hermetically-sealed ceramic package as CCD because
the bonding wires can become disconnected due to resonance during the cleaning process.
