1 ABOUT LEAD FREE SOLDER (PbF: Pb free)

Note:

In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that

contains lead.

We will use PbF Solder when discussing the lead free solder used in our manufacturing process which is made from Tin (Sn),

Silver (Ag), and Copper (Cu).

This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair

work we suggest using the same type of solder.

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).

•

• •

• Exercise care while using higher temperature soldering irons.:

Do not heat the PCB for too long time in order to prevent solder splash or damage to the PCB.

•

• •

• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F (600°C).

•

• •

• When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the

opposite side (See the figure below).

1.1. Suggested PbF 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 with other

materials.

The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3 mm, 0.6 mm and 1.0 mm.

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 foil.

2.Ground the soldering irons.

3.Use a conductive mat on the worktable.

4.Do not touch IC or LSI pins with bare fingers.
