CHAPTER 1. GENERAL DESCRIPTION
[1] PRECAUTION FOR USING LEAD-FREE SOLDER
1. Employing lead-free solder
"MAIN,DISPLAY,TERMINAL,SWITCH,POWER,JACK,TUNER,DVD,MICVIDEOOUT,CDCHANGERMOTOR(PWBONLY),
LED PWB" of this model employs lead-free solder.
The LF symbo lindicates lead-free solder,and is attached on the PWB and service manuals.The alphabetical character
following LF shows the type of lead-free solder.
Example:
Indicates lead-free solder of tin,silver and copper.
2. Using lead-free wire solder
When fixing the PWB soldered with the lead-free solder,apply lead-free wire solder. Repairing with conventional lead wire solder
may cause damage or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 C, were commend you to use a
dedicated soldering bit,if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station
or service branch in your area.
3. Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 C which is higher than the conventional lead solder by 40 C,
and as it has poor solder wettability,you may be apt to keep the soldering bit in contact with the PWB for extended period of
time. However, Since the land may be peeled off or the maximum heat-resistance temperature of parts may be exceeded,
remove the bit from the PWB assoonas you confirm the steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corrected. Make sure to turn on and off the
power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use
of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
Be careful when replacing parts with polarity indication on the PWB silk.

Instructions for Handling
Semi-conductors
Electrostatic breakdown of the semi-conductors may
occur due to a potential difference caused by electrostatic
charge during unpacking or repair work.
1. Ground for Human Body
Be sure to wear a grounding band (1MΩ) that is properly
grounded to remove any static electricity that may be
charged on the body.
2. Ground for Workbench
Be sure to place a conductive sheet or copper plate with
proper grounding (1MΩ) on the workbench or other
surface, where the semi-conductors are to be placed.
Because the static electricity charge on clothing will not
escape through the body grounding band, be careful to
avoid contacting semi-conductors with your clothing.

Pin Definitions:
Pin NumberPin NamePin Function Description
1GND
2Vcc
3Vfb
4Ipk
5Vstr
Sense FET source terminal on primary side and internal control ground.
Positive supply voltage input. Although connected to an auxiliary transformer
winding, current is supplied from pin 5 (Vstr) via an internal switch during startup
(see Internal Block Diagram section). It is not until Vcc reaches the UVLO upper
threshold (12V) that the internal start-up switch opens and device power is
supplied via the auxiliary transformer winding.
Feedback voltage pin is the non-inverting input to PWM comparator. It has a
0.9mA current source connected internally while a capacitor and optocoupler are
typically connected externally. A feedback voltage of 6V triggers over load
protection (OLP). There is a time delay while charging between 3V and 6V using
an internal 5uA current source, which prevents false triggering under transient
conditions but still allows the protection mechanism to operate under true
overload conditions.
Pin to adjust the current limit of the Sense FET. The feedback 0.9mA current
source is diverted to the parallel combination of an internal 2.8kΩ resistor and any
external resistor to GND on this pin to determine the current limit. If this pin is tied
to Vcc or left floating, the typical current limit will be 1.2A.
This pin connects directly to the rectified AC line voltage source. At start up the
internal switch supplies internal bias and charges and external storage capacitor
placed between the Vcc pin and ground. Once the Vcc reaches 12V, the internal
switch is disabled.
6, 7, 8Drain
Pin Configuration:
The Drain pin is designed to connect directly to the primary lead of the transformer and is capable of switching a maximum of 650V. Minimizing the length of
the trace connecting this pin to the transformer will decrease leakage inductance.
