SAFETY CHECK-OUT

After correcting the original problem, perform the following

safety check before return the product to the customer.

1. Check the area of your repair for unsoldered or poorly

soldered connections. Check the entire board surface

for solder splasher and bridges.

2. Check the interboard wiring to ensure that no wires are

“pinched” or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly

transistors, that were installed during a previous repair.

Point them out to the customer and recommend their

replacement.

4. Look for parts which, though functioning, show obvious

signs of deterioration. Point them out to the customer

and recommend their replacement.

5. Check the B + voltage to see it is at the values

specified.

6. Make leakage - current measurements to determine

that exposed parts are acceptably insulated from the

supply circuit before returning the product to the

customer.

RoHS lead-free compliance

Because this product is RoHS lead-free compliant, use the designated after-sales parts and the designated lead-free solder when performing repairs.

With the exception of parts and materials expressly excluded from the RoHS directive (*1), all the internal connections and component parts and materials used in this product are lead-free compliant (*2) under the European RoHS directive.

*1: Excluded items (list of the main lead-related items)

• Lead included in glass used in fluorescent tubes, electronic components and cathode-ray tubes

• Lead in high-melting-point solder (i.e. tin-lead solder alloys that contain 85% lead or more)

• Lead in ceramic electronic parts (piezo-electronic devices)

• Mercury contained in fluorescent tubes is also excluded.

*2: Definition of lead-free

A lead content ratio of 0.1 wt% or less in the applicable locations (solder, terminals, electronic components, etc.)

<Reference> RoHS: The name of a directive issued by the European Parliament aimed at restricting the use of

certain designated hazardous substances included in electrical and electronic equipment.

Designated substances (6): Lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs) and

polybrominated diphenyl ether (PBDE)

<Lead-free soldering>

When carrying out repairs, use a designated lead-free solder, bearing in mind the differing work practices for conventional solder (eutectic) and lead-free solder.



 Differences in the soldering work for lead-free and eutectic solder



When the soldering work practices for eutectic solder and lead-free solder are compared, the main differences are as shown below. In particular, when lead-free solder is used, the solder tends to be less workable than when eutectic solder is used. Accordingly, the soldering techniques used must take that into account.

Difference

The solder starts melting later.

Poor wetting

Solder feed rate is difficult to control.

Wetting the insides of through holes is especially

difficult.

During repairs (or modifications) removing solder from inside through holes is difficult.

There is serious carbonization of the soldering iron.

The surface is not glossy.

The initial melting point of lead-free solder is high, so you have to get used to it. Move the tip of the soldering iron around to heat the entire connection to the melting temperature and assist wetting. Use the solder (wire) diameter and soldering iron that are best suited to connection being soldered. First apply solder to the area immediately around the through hold and then feed the solder into the hole. Use a suitable wicking wire (with a suitable method and heating) and a suction tool. Either put solder onto the soldering iron tip after completing the work, or turn the iron off frequently. Learn to recognize the appearance of the surface.

Countermeasure

FinePix A600 Service Manual



 Setting temperature during lead-free soldering



• Lead-free solder melting temperature The melting point of eutectic (Sn-Pb) solder is 183°C, while the melting point of lead-free solder (Sn-Ag-Cu) is 30°C higher at 220°C.

• Soldering iron tip temperature The temperature setting for the soldering iron used should be such that the tip of the soldering iron is at the correct bonding temperature for the connection. This temperature is normally set at around 100°C higher than the melting point of the solder. However, the actual temperature should take into account the shape and size of the soldering iron tip, the heat tolerance of the connection and the workability of that temperature.

• Correct bonding temperature The correct bonding temperature refers not to the temperature of the heat source, but to the bonding temperature that will give the best bond strength.



 Precautions when soldering with lead-free solder



• Soldering iron maintenance Because of the high soldering iron temperature in lead-free soldering, there is rapid carbonization of the flux adhering to the tip of the soldering iron. (1) Always cover the tip of the soldering iron with solder when it is not being used. (2) If the tip is black from carbonization, wipe it gently with a paper towel soaked in alcohol until the solder will wet.

• Uniform heating of the board and components To ensure that the lead-free solder wets the entire surface of the pattern and the lands despite its poor wetting characteristics, you must move the tip of the soldering iron over a wide area to raise the temperature of the entire connection.



 Soldering iron



A soldering iron with a temperature control is best.

1. General

1-2. Explanation of Terms

Deactivated batteries: Leaving an Ni-MH battery unused in storage for a long period may cause a rise in the level

of substances that inhibit current flow inside the battery and result in a dormant battery.

A battery in this state is referred to as deactivated.

Because current flow is inhibited in a deactivated Ni-MH battery, the battery’s original

level of performance cannot be achieved.

EV: A number denotes Exposure Value. The EV is determined by the brightness of the subject

and sensitivity (speed) of the film or CCD. The number is larger for bright subjects and

smaller for dark subjects. As the brightness of the subject changes, a digital camera

maintains the amount of light hitting the CCD at a constant level by adjusting the aperture

and shutter speed.

When the amount of light striking the CCD doubles, the EV increases by 1. Likewise, when

the light is halved, the EV decreases by 1.

Frame rate (fps): The frame rate refers to the number of images (frames) that are photographed or played

back per second. For example, when 10 frames are continuously photographed in a 1-

second interval, the frame rate is expressed as 10 fps.

For reference, TV images are displayed at 30 fps (NTSC).

JPEG: Joint Photographic Experts Group

A file format used for compressing and saving color images. The higher the compression

rate, the greater the loss of quality in the decompressed (restored) image.

Memory effect: If an Ni-MH battery is repeatedly charged without first being fully discharged, its perfor-

mance may drop below its original level. This is referred to as the “memory effect”.

Motion JPEG: A type of AVI (Audio Video Interleave) file format that handles images and sound as a

single file. Images in the file are recorded in JPEG format. Motion JPEG can be played

back by QuickTime 3.0 or later.

Smear: A phenomenon specific to CCDs whereby white streaks appear on the image when there

is a very strong light source, such as the sun or reflected sunlight, in the photography

screen.

WAVE A standard format used on Windows systems for saving audio data. WAVE files have the

“.WAV” file extension and the data can be saved in either compressed or uncompressed

format. Uncompressed recording is used on this camera.

WAVE files can be played back on a personal computer using the following software:

Windows: MediaPlayer

Macintosh: QuickTime Player

* QuickTime 3.0 or later

White Balance: Whatever the kind of the light, the human eye adapts to it so that a white object still looks

white. On the other hand, devices such as digital cameras see a white subject as white by

first adjusting the color balance to suit the color of the ambient light around the subject.

This adjustment is called matching the white balance.

Exif Print: Exif Print Format is a newly revised digital camera file format that contains a variety of

shooting information for optimal printing.

3-3. Functions of Primary Blocks

3-3-1. Technical Outline

 Equipped with a 1/1.7-inch Super CCD HR (with 6.3 effective megapixels) and a Fujinon 3x optical zoom lens.  Features a image signal processing LSI chip, called the XCS2R_IC (IC203, CSP_IC), built into the MAIN PWB ASSY.

This CPU incorporates the standard peripheral I/O functions as well as the peripheral functions required for still image processing into a single chip. Standard peripheral I/O consists of the interrupt controller, DMA controller, clock controller, SDRAM controller, block selection controller, serial I/O, multifunction timer, monitoring timer, programmable I/O ports, USB 2.0 (Full Speed), microprocessor ADC, microprocessor DAC, image processing circuit, JPEG compression/ expansion circuit, display control circuit, still image processing and card interface circuit.

 In the white balance procedure, an algorithm has been installed that provides an estimation of the light source used for

shooting based on the brightness and light source color detected when the shot was taken, and a white balance (WB) compensation function based on that estimation. The new algorithm is designed to prevent “hunting” due to field-of-view slippage by providing more accurate brightness and color detection, and to allow the installation of a powerful algorithm for distinguishing between the light source and the original subject colors.

 Flash brightness is adjusted using the CCD-TTL method in which the flash brightness is calculated from the CCD

feedback data generated by the pre-flash.

Explanation of the imaging circuit functions

 Analog video signals output from the CCD (1/1.7-inch with 6.3 effective megapixels) undergo pseudo-color correction

processing, adaptive interpolation processing, amplification and signal mixing in the BCS-R_IC (IC103; CSP_IC). The converted digital signals are then sent to the single-chip image signal processing LSI chip, known as XCS2R_IC (IC203,

CSP_IC).  Input data from the CCD * The 10-bit digital image data (corresponding to 1H) sent from the imaging circuit (BCS-R) is sent to XCS2R_IC, buffered

in the chip’s IBFC and replaced by 16-bit (96 MHz) data. The replaced 16-bit (96 MHz) image data is then stored in the

XCS2R_IC [SDRAM] via the XCS2R_IC [I/O BUFFER]. The image data for each frame is temporarily stored in the

XCS2R_IC [SDRAM]. * At the same time, the AE for [AUTO] is calculated using the 10-bit image data input to XCS2R_IC and the data required

for AE, AWB and AF is sent to the XCS2R_IC [SDRAM]. In the XCS2R_IC [SDRAM], the data is sent serially to AFE_CS

to obtain the correct AE, AWB and AF.  Recording onto an xD-Picture card

The image data stored in SDRAM is converted to 16-bit (96-MHz) data by [IBFC] in XCS2R_IC one line at a time and

then sent to [YC PRO]. In [IBFC], the 32-bit Y and C signals are each converted to 8-bit Y, Y, Cb and Cr signals and sent

to the XCS2R_IC [SDRAM]. The image data stored in the XCS2R_IC [SDRAM] is compressed using [JPEG] in

XCS2R_IC and then recorded sequentially onto the xD-Picture card via [MEDIA] in XCS2R_IC.  Playing back images from an xD-Picture card

The compressed image data from the xD-Picture card is sent to XCS2R_IC and stored in the XCS2R_IC [SDRAM] via

[MEDIA]. The compressed image data stored in the XCS2R_IC [SDRAM] is expanded using [JPEG] and again stored in

the XCS2R_IC [SDRAM]. The expanded image data is sent to [YC PRO] via [IBFC]. In [YC PRO], gain control and

aperture processing is applied for the brightness signals and color difference signals, after which the data is again stored

in the XCS2R_IC [SDRAM]. The image data is then displayed via [ENCD] and [D/A].  In movie shooting mode

The 10-bit digital image data output from the imaging unit is converted to 8-bit Y and C signals by the XCS2R_IC [YC

PRO] and sent to the XCS2R_IC [SDRAM]. The image data is compressed using [JPEG] in XCS2R_IC and again stored

in the XCS2R_IC [SDRAM]. The compressed data is then recorded sequentially onto the xD-Picture card via [MEDIA] in

XCS2R_IC.  The imaging system adjustment data is stored in FLASH_ROM (IC202).

Explanation of the LCD controller functions

 The R, G and B signals processed in the XCS2R_IC image signal processor are output to the LCD panel via [LCD

CONST].

LCD Unit

 The LCD monitor (1.8-inch 77,000 pixels) used in the camera uses a low-temperature polysilicon TFT color LCD screen.
