3.2.3 Assembly/Disambly of [14] OP BLOCK ASSY/CCD BOARD ASSY
z Precautions
(1) Be careful in handling the CCD IMAGE SENSOR, OPTI-
CAL LPF and the LENS components.
Pay special attention to the surfaces to protect them from
stains, dust, or scratches.
If the surfaces are soiled with finger prints or other stains,
wipe them off with silicon paper, clean chamois leather,
or recommended 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 ASSY.
z Disassembly of OP BLOCK ASSY / CCD BOARD ASSY
(1) Unsolder the 20 soldered points (SD14a) of the CCD
BOARD ASSY.
(2) Remove the 2 screws (1,2), and then remove the CCD
BOARD ASSY,SHIELD(CCD) and the CCD BASE AS-
SY.
NOTE14a:
When removing the CCD BASE ASSY, be careful in
handling as the CCD IMAGE SENSOR may be re-
moved together with the SHEET and the OP LPF at-
tached.
NOTE14b:
Replace the CCD IMAGE SENSOR as a CCD BASE
ASSY, not as a single part replacement.
(3) Remove the SHEET and OP LPF.
z Assembly of OP BLOCK ASSY / CCD BOARD ASSY
(1) Set the OP LPF first, and then the SHEET to the OP
BLOCK ASSY.
NOTE14c:
Be careful with the attachment direction of the OP
LPF.
(2) Attach the CCD BASE ASSY first, then the SHEET,
SHIELD(CCD) and the CCD BOARD ASSY so that the
SHEET stays in place, and then tighten with the 2 screws
(1,2).
(3) Solder the 20 points (SD14a) on the CCD BOARD AS-
SY.
z Replacement of service repair parts
The service repair parts for the OP BLOCK ASSY are as listed
below.
When replacing parts, be careful not to cut the FPCs or dam-
age any parts by soldering (excessive heat).
(1) FOCUS MOTOR UNIT
(2) ZOOM MOTOR UNIT
(3) IRIS MOTOR UNIT
NOTE 14d:
The IRIS MOTOR UNIT includes the FPC ASSY and two
sensors.
