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 degrees C (86

°F) more than that

of the normal solder.

• 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 PCB 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 PCB 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).

• 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)

* Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%

The letter of “PbF” is printed either foil side or components side on the PCB using the lead free solder.

DMR-EH49A/EH59A/EX79A series are improved versions of DMR-EH49/EH495/EH59/EH595/EX79 series with better perfor-
mance of the DVD drive and the Digital P.C.B..

Make sure to check if it is the “A” model by confirming the serial number on the rear panel before ordering the replacement part.
