IMPORTANT INFORMATION ABOUT LEAD FREE, (PbF), SOLDERING

If lead free solder was used in the manufacture of this product the printed circuit boards will be marked PbF, Standard laded, (Pb),

solder can be used as usual on boards without the PbF mark.

When this mark does appear please read and follow the special instructions described in this manual on the use of PbF and how

it might be permissible to use Pb solder during service and repair work.

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 although, with some precautions, standard Pb solder can also be used.

Caution

•

• •

• PbF solder has a melting point that is 50° ~ 70° F, (30° ~ 40°C) higher than Pb solder. Please use a soldering iron with

temperature control and adjust it to 700° ± 20° F, (370° ± 10°C). In case of using high temperature soldering iron, please

be careful not to heat too long.

•

• •

• PbF solder will 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 which may flow onto the

opposite side (See 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: 0.3mm, 0.6mm and 1.0mm.

1.2. HOW TO RECOGNIZE THAT Pb FREE SOLDER IS USED

KX-TDA6181X

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 part´s boxes with aluminum foil.

2. Ground the soldering irons.

3. Use a conductive mat on the worktable.

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

3 GENERAL DESCRIPTION

This card is inserted in the free slot of the TDA600 system and is capable of connecting 16 analog loop start lines.

Up to 2 CALLER ID/PAYTONE card can be added on as option cards.

The LPR is an SH-1 (SH7020) with 512Kbyte flash ROM and 128Kbyte SRAM, and supports software version upgrade though

downloading.
