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 dust to scratch the glass.

2. Electrostatic Damage

As compared with general MOS-LSI, CCD has

lower ESD. Therefore, take the following anti-static

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.
