PRECAUTIONS FOR BUILT-IN LENS CCD AREA SENSORS

ø Dust from static electricity should be blown

off with an ionized air blower. For anti-

electrostatic measures, however, ground all

the leads on the device before blowing off

the dust.

ø The contamination on the surface of the lens

should be wiped off with a clean applicator

soaked in isopropyl alcohol. Wipe slowly and

gently in one direction only.

– Frequently replace the applicator and do not

use the same applicator to clean more than

one device.

ø Make sure there is no dust or contamination

on the lens and screw it on the lens holder.

4. Other

1) Soldering should be manually performed under

the following conditions :

ø Use ESD-measured soldering iron

ø The conditions of the soldering time in which

the soldering iron touches the package,

differs by the shape and the temperature of

the iron end. Refer to the table below and

take great care in soldering.

SOLDERING TIME

R0.5

17

(Unit : mm)

Below 350 ˚C

Time touching the package should be less than 40 seconds

Below 300 ˚C

Time touching the package should be less than 25 seconds

0.5

6.5

17

(Unit : mm)

Below 275 ˚C

Time touching the package should be less than 35 seconds

– In case where the soldering may exceed the

time mentioned above, resume the work

after the device returns to normal

temperature.

ø Do not put too much force onto the lens and

the lens holder while soldering.

ø Be careful not to let the soldering iron touch

the lens holder.

– Soldering can be quickly/neatly done by

laying the soldering iron so it lightly touches

the border between the package and the

circuit board and sliding it in sideways.

2) There is no guarantee of the performance of

the device which has been removed or

resoldered after being soldered once under the

conditions mentioned above.

– In case there seems to be an inferior device,

consult with our sales office before removing

it.

3) Avoid using or storing the CCD at high

temperature or high humidity as it is a precise

optical component. Do not give a mechanical

shock to the CCD.

4) Do not expose the device to strong light. For

the color device, long exposure to strong light

will fade the color of the color filters.
