1 ABOUT LEAD REE SOLDER (Pb : Pb free)
Note:
In the information belo , Pb, the symbol for lead in the periodic table of elements, ill refer to standard solder or solder that
contains lead.
We ill use PbF solder hen discussing the lead free solder used in our manufacturing process hich is made from Tin (Sn),
Silver (Ag), and Copper (Cu).
This model, and others like it, manufactured using lead free solder ill have PbF stamped on the PCB. For service and repair
ork e suggest using the same type of solder although, ith some precautions, standard Pb solder can also be used.
Caution
· PbF solder has a melting point that is 50°F ~ 70°F (30°C ~ 40°C) higher than Pb solder. Please use a soldering iron ith
temperature control and adjust it to 700°F ± 20°F (370°C ± 10°C). In case of using high temperature soldering iron, please
be careful not to heat too long.
· PbF solder ill tend to splash if it is heated much higher than its melting point, approximately 1100°F (600°C).
· If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possible
and be sure that any remaining is melted prior to applying the Pb solder.
· When applying PbF solder to double layered boards, please check the component side for excess hich may flo onto the
opposite side (See the figure belo ).
1.1. Suggested Pb Solder
There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper
(Sn+Ag+Cu), you can also use Tin and Copper (Sn+Cu) or Tin, Zinc, and Bismuth (Sn+Zn+Bi). Please check the
manufacturer’s specific instructions for the melting points of their products and any precautions for using their product ith other
materials.
The follo ing lead free (PbF) solder ire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

2 OR SERVICE TECHNICIANS
ICs and LSIs are vulnerable to static electricity.
When repairing, the following precautions will help prevent recurring malfunctions.
1. Cover the plastic parts boxes ith aluminum foil and ground them.
2. Ground the soldering irons.
3. Use a conductive mat on the orktable.
4. Do not touch IC or LSI pins ith bare fingers.
3 CAUTION
Danger of explosion if battery is incorrectly replaced. Replace only ith the same or equivalent type recommended by the
manufacturer.
Dispose of used batteries according to the manufacture’s Instructions.
