NOTES ON HANDLING THE PACKAGES
1 DUST AND DIRT PROTECTING
The optical characteristics of the CCD will be degraded if the cap is scratched during cleaning. Don’t either
touch plastic cap surface by hand or have any object come in contact with plastic cap surface. Should dirt
stick to a plastic cap surface, blow it off with an air blower. For dirt stuck through electricity ionized air is
recommended. And if the plastic cap surface is grease stained, clean with our recommended solvents.
CLEANING THE PLASTIC CAP
Care should be taken when cleaning the surface to prevent scratches.
We recommend cleaning the cap with a soft cloth moistened with one of the recommended solvents below.
Excessive pressure should not be applied to the cap during cleaning. If the cap requires multiple cleanings it is
recommended that a clean surface or cloth be used.
RECOMMENDED SOLVENTS
The following are the recommended solvents for cleaning the CCD plastic cap.
Use of solvents other than these could result in optical or physical degradation in the plastic cap.
Please consult your sales office when considering an alternative solvent.
Solvents
Ethyl Alcohol
Methyl Alcohol
Isopropyl Alcohol
N-methyl Pyrrolidone
Symbol
EtOH
MeOH
IPA
NMP
2 MOUNTING OF THE PACKAGE
The application of an excessive load to the package may cause the package to warp or break, or cause chips
to come off internally. Particular care should be taken when mounting the package on the circuit board. Don't
have any object come in contact with plastic cap. You should not reform the lead frame. We recommended to
use a IC-inserter when you assemble to PCB.
Also, be care that the any of the following can cause the package to crack or dust to be generated.
1. Applying heat to the external leads for an extended period of time with soldering iron.
2. Applying repetitive bending stress to the external leads.
3. Rapid cooling or heating
3 OPERATE AND STORAGE ENVIRONMENTS
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)
4 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 MΩ.
