1 ABOUT LEAD FREE SOLDER ( bF: b free)
Note:
In the in ormation below, Pb, the symbol or lead in the periodic table o elements, will re er to standard solder or solder that
contains lead.
We will use PbF solder when discussing the lead ree solder used in our manu acturing process which is made rom Tin (Sn),
Silver (Ag), and Copper (Cu).
This model, and others like it, manu actured using lead ree solder will have PbF stamped on the PCB. For service and repair
work we suggest using the same type o solder although, with 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 with
temperature control and adjust it to 700°F ± 20°F (370°C ± 10°C). In case o using high temperature soldering iron, please
be care ul not to heat too long.
• • •
• PbF solder will tend to splash i it is heated much higher than its melting point, approximately 1100°F (600°C).
• • •
• I you must use Pb solder on a PCB manu actured using PbF solder, remove as much o 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 or excess which may low onto the
opposite side (See the igure below).
1.1. Suggested bF Solder
There are several types o PbF solder available commercially. While this product is manu actured 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
manu acturer’s speci ic instructions or the melting points o their products and any precautions or using their product with other
materials.
The ollowing lead ree (PbF) solder wire sizes are recommended or service o this product: 0.3mm, 0.6mm and 1.0mm.

Note:
The location o the “PbF” mark is subject to change without notice.
2 FOR 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 with aluminum oil and ground them.
2. Ground the soldering irons.
3. Use a conductive mat on the worktable.
4. Do not touch IC or LSI pins with bare ingers.
3 CAUTION
1. Danger o explosion i battery is incorrectly replaced.
2. Replace only with the same or equivalent type recommended by the manu acturer.
3. Dispose o used batteries according to the manu acture’s Instructions.
