WARNING
Do not use solder containing lead.
This product has been manufactured using lead-free solder in
order to help preserve the environment.
Because of this, be sure to use lead-free solder when carrying
out repair work, and never use solder containing lead.
Lead-free solder has a melting point that is 30 - 40°C (86 104°F) higher than solder containing lead, and moreover it does
not contain lead which attaches easily to other metals. As a
result, it does not melt as easily as solder containing lead, and
soldering will be more difficult even if the temperature of the
soldering iron is increased.
The extra difficulty in soldering means that soldering time will
increase and damage to the components or the circuit board
may easily occur.
Because of this, you should use a soldering iron and solder
that satisfy the following conditions when carrying out repair
work.
Soldering iron
Use a soldering iron which is 70 W or equivalent, and which
lets you adjust the tip temperature up to 450°C (842°F). It
should also have as good temperature recovery characteristics as possible.
Set the temperature to 350°C (662°F) or less for chip components, to 380°C (716°F) for lead wires and similar, and to 420°C
(788°F) when installing and removing shield plates.
The tip of the soldering iron should have a C-cut shape or a
driver shape so that it can contact the circuit board as flat or in
a line as much as possible.
Note:
If replacing existing solder containing lead with lead-free solder in the soldered parts of products that have been manufactured up until now, remove all of the existing solder at those
parts before applying the lead-free solder.
Solder
Use solder with the metal content and composition ratio by
weight given in the table below. Do not use solders which do
not meet these conditions.

3. Part of IC905 (generation of vertical transfer clock,
H Driver) and IC901 (V Driver)
An H driver (part of IC905) and V driver (IC901) are necessary in order to generate the clocks (vertical transfer clock,
horizontal transfer clock and electronic shutter clock) which
driver the CCD.
IC905 has the generation of horizontal transfer clock and the
function of H driver, and is an inverter IC which drives the
horizontal CCDs (H1 and H2). It carries out generating vertical transfer clock, and output to IC901.
In addition the XV1-XV6 signals which are output from IC905
are vertical transfer clocks, and the XSG signal is superimposed onto XV1, XV3 and XV5 at IC901 in order to generate
a ternary pulse. In addition, the XSUB signal which is output
from IC101 is used as the sweep pulse for the electronic shutter, and the RG signal which is output from IC905 is the reset
gate clock.
4. IC905 (H Driver, CDS, AGC and A/D converter)
IC905 contains the functions of H driver, CDS, AGC and A/D
converter. As horizontal clock driver for CCD image sensor,
HØ1 (A and B) and HØ2 (A and B) are generated inside, and
output to CCD.
The video signal which is output from the CCD is input to pin
(A6) of IC905. There are sampling hold blocks generated from
the SHP and SHD pulses, and it is here that CDS (correlated
double sampling) is carried out.
After passing through the CDS circuit, the signal passes
through the AGC amplifier (VGA: Variable Gain Amplifier). It
is A/D converted internally into a 14-bit signal, and is then
input to ASIC (IC101). The gain of the VGA amplifier is controlled by pin (A2), (B3) and (C4) serial signal which is output
from ASIC (IC101).
