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. IC905 (H Driver) and IC901 (V Driver)

An H driver (a 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 clock generating which drives horizontal CCD and its drives function. These clocks are output from pin (14), (15), (18) and (19) of IC905. In addition the XV1-XV8 signals which are output from IC101 are the vertical transfer clocks, and the XSG1A, XSG1B, XSG3A, XSG3B, XSG5A, XSG5B, XSG7A and XSG7B signals which are output is superimposed onto XV1, XV3, XV5 and XV7 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 pin (21) of IC905 is the reset gate clock.

4. IC905 (CDS, AGC Circuit and A/D Converter)

The video signal which is output from the CCD is input to pins (27) of IC905. There are S/H blocks inside IC905 generated from the XSHP and XSHD 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. It is A/C converted internally into a 12-bit signal, and is then input to IC101 of the CP1 circuit board. The gain of the AGC amplifier is controlled by pin (31)(33) serial signal which is output from IC101 of the CP1 board.
