3.2.5 ASSEMBLY/DISASSEMBLY OF [14] OP BLOCK ASSMBLY/CCD BOARD ASSEMBLY
z Precautions
(1) Be careful in handling the CCD IMAGE SENSOR, OPTI-
CAL LPF and the LENS components. Pay special atten-
tion not to soil or damage the surfaces., especially with
regard to surface contamination, attached dust or
scratching. If fingerprints are present on the surface they
should be wiped away using either a silicon 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 ASSY.
z Disassembly of OP BLOCK ASSEMBLY / CCD BOARD AS-
SEMBLY
(1) Unsolder the fourteen soldered points (SD14a) of the
CCD BOARD ASSY.
(2) Remove the two screws (1,2), and then remove the CCD
BOARD ASSY,SHELD(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 SHIEET and the OP LPF.
z Aembly of OP BLOCK ASSEMBLY / CCD BOARD ASSEM-
BLY
(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 and
the CCD BOARD ASSY so that the SHEET stays in
place, and then tighten with the two screws (1, 2).
(3) Solder the 14 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:
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 14e:
The IRIS MOTOR UNIT includes the FPC ASSY and two
sensors.
