PRECAUTIONS FOR CCD AREA SENSORS
1. Package Breakage
In order to prevent the package from being broken,
observe the following instructions :
1) The CCD is a precise optical component and
the package material is ceramic or plastic.
Therefore,
ø Take care not to drop the device when
mounting, handling, or transporting.
ø Avoid giving a shock to the package.
Especially when leads are fixed to the socket
or the circuit board, small shock could break
the package more easily than when the
package isn’t fixed.
2) When applying force for mounting the device or
any other purposes, fix the leads between a
joint and a stand-off, so that no stress will be
given to the jointed part of the lead. In addition,
when applying force, do it at a point below the
stand-off part.
(In the case of ceramic packages)
– The leads of the package are fixed with low
melting point glass, so stress added to a
lead could cause a crack in the low melting
point glass in the jointed part of the lead.

(In the case of plastic packages)
– The leads of the package are fixed with
package body (plastic), so stress added to a
lead could cause a crack in the package
body (plastic) in the jointed part of the lead.

3) When mounting the package on the housing,
be sure that the package is not bent.
– If a bent package is forced into place
between a hard plate or the like, the pack-
age may be broken.
4) If any damage or breakage occurs on the sur-
face of the glass cap, its characteristics could
deteriorate.
Therefore,
ø Do not hit the glass cap.
ø Do not give a shock large enough to cause
distortion.
ø Do not scrub or scratch the glass surface.
– Even a soft cloth or applicator, if dry, could
cause flaws to scratch the glass.
2. Electrostatic Damage
As compared with general MOS-LSI, CCD has
lower ESD. Therefore, take the following antistatic
measures when handling the CCD :
1) Always discharge static electricity by grounding
the human body and the instrument to be used.
To ground the human body, provide resistance
of about 1 M$ between the human body and
the ground to be on the safe side.
2) When directly handling the device with the
fingers, hold the part without leads and do not
touch any lead.
