3.2.4 ASSEMBLY/DISASSEMBLY OF [18] OP BLOCK ASSEMBLY/CCD BOARD ASSEMBLY
Precautions
(1) Take care in handling the CCD IMAGE SENSOR, OPTICAL
LPF and lens components when performing maintenance
etc., especially with regard to surface contamination, at-
tached dust or scratching. If fingerprints are present on
the surface they should be wiped away using either a sil-
icon paper, clean chamois or the cleaning cloth.
(2) The CCD IMAGE SENSOR may have been shipped with
a protective sheet attached to the transmitting glass.
When replacing the CCD IMAGE SENSOR, do not peel
off this sheet from the new part until immediately before
it is mounted in the OP BLOCK ASSEMBLY.
(3) As the attachment direction of the OPTICAL LPF is im-
portant, be careful when removing it. Make sure to reat-
tach the OP LPF in its original direction.
Disassembly of OP BLOCK ASSEMBLY / CCD BOARD AS-
SEMBLY
(1) Unsolder the fourteen soldered points (SD18a) of the
CCD BOARD ASSEMBLY.
(2) Remove the two screws (1, 2), and then remove the CCD
BOARD ASSEMBLY, SHIELD CCD and the CCD BASE
ASSEMBLY.
NOTE18a:
Be careful in handling as there are only the OPTICAL
LPF and the SHEET stored inside the OP BLOCK
ASSY when the CCD BASE ASSY is removed.
NOTE18b:
Replace the CCD IMAGE SENSOR as a CCD BASE
ASSEMBLY, not as a single part replacement.

Assembly of OP BLOCK ASSEMBLY / CCD BOARD AS-
SEMBLY
(1) Set the OPTICAL LPF first, and then the SHEET to the
OP BLOCK ASSEMBLY.
NOTE18c:
Pay careful attention to the orientation of the OPTICAL
LPF.
(2) Attach the CCD BASE ASSEMBLY first then the SHIELD
CCD, CCD BOARD ASSEMBLY so that the SHEET
stays in place, and tighten with the two screws (1, 2).
(3) Solder the 14 points (SD18a) on the CCD BOARD AS-
SY.
Replacement of service repair parts
The service repair parts for the OP BLOCK ASSEMBLY are as
listed below.Take special care not to disconnect any of the FPC
wires or cause any damage due to soldering (excessive heating).
(1) FOCUS MOTOR UNIT
(2) ZOOM MOTOR UNIT
(3) AUTO IRIS UNIT
NOTE18d:
When replacing the FOCUS MOTOR UNIT or the ZOOM
MOTOR UNIT, solder the FPC at a space of about 0.5 mm
above the terminal pin.
NOTE 18e:
The AUTO IRIS UNIT includes the FPC ASSEMBLY and
two sensors.
