(Definition: The letter of
is printed on the P.C.B. using the lead free solder.)
To put lead free solder, it should be well molten and mixed with the original lead free solder.
Remove the remaining lead free solder on the P.C.B. cleanly for soldering of the new IC.
Since the melting point of the lead free solder is higher than that of the normal lead solder, it takes the longer time to melt the lead free solder.
Use the soldering iron (more than 70W) equipped with the temperature control after setting the temperature at 350±30 degrees C (662±86 °F).
Recommended Lead Free Solder (Service Parts Route.)
The following 3 types of lead free solder are available through the service parts route.
RFKZ03D01KS-----------(0.3mm 100g Reel)
RFKZ06D01KS-----------(0.6mm 100g Reel)
RFKZ10D01KS-----------(1.0mm 100g Reel)
Note
* Ingredient: tin (Sn) 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%
3.6 How to Define the Model Suffix (NTSC or PAL model)
There are seven kinds of DMC-FT25/TS25, regardless of the colours.
a) DMC-FT25 (Japan domestic model.)
b) DMC-TS25P/PC
c) DMC-FT25EB/EF/EG/EP
d) DMC-FT25EE
e) DMC-FT25GN
f) DMC-TS25GK
g) DMC-FT25GA/GC/GF, DMC-TS25PU
What is the difference is that the "INITIAL SETTINGS" data which is stored in Flash ROM mounted on Main P.C.B.
3.6.1 Defining methods
To define the model suffix to be serviced, refer to the nameplate which is putted on the bottom side of the Unit.
Note:
After replacing the Main P.C.B., be sure to achieve adjustment.
The Maintenance software (DIAS) is available at "software download" on the "Support Information from NWBG/VDBG-AVC" web-site in "TSN system".
