If the circuit is changed or modified, the information will be followed by service manual to be controlled with original
service manual.
3.2 General Description About Lead Free Solder
(PbF)
The lead free solder has been used in the mounting process of all electrical components on the printed circuit boards
used for this equipment in considering the globally environmental conservation.
The normal solder is the alloy of tin (Sn) and lead (Pb). On the other hand, the lead free solder is the alloy mainly
consists of tin (Sn), silver (Ag) and Copper (Cu), and the melting point of the lead free solder is higher approx.30°C (86°
F) more than that of the normal solder.
Distinction of P.C.B. Lead Free Solder being used
Service caution for repair work using Lead Free Solder (PbF)
The lead free solder has to be used when repairing the equipment for which the lead free solder is used.
(Definition: The letter of “PbF” 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°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%
3.3 How to Define the Model Suffix
There are two kinds of HC-MDH2/MDH2M.
a) HC-MDH2GK
b) HC-MDH2GC, MDH2MGC
What is the difference is that the “INITIAL SETTING” data which is stored in Flash ROM mounted on Main P.C.B..
