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 thatcontains 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 repairwork 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 ~ 40C) higher than Pb solder. Please use a soldering iron withtemperature control and adjust it to 700 20 F, (370 10C). In case of using high temperature soldering iron, pleasebe careful not to heat too long.

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

If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possibleand 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 theopposite side (See figure, below).

1.1. SUGGESTED PbF SOLDERThere 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 themanufacturers specific instructions for the melting points of their products and any precautions for using their product with othermaterials.The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

3 CAUTION3.1. SAFETY PRECAUTIONS 1. Before servicing, unplug the power cord to prevent an electric shock. 2. When replacing parts, use only the manufacturers recommended components for safety. 3. Check the condition of the power cord. Replace if wear or damage is evident. 4. After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc. 5. Before returning the serviced equipment to the customer, be sure to perform the following insulation resistance test to prevent

the customer from being exposed to shock hazards.

3.2. INSULATION RESISTANCE TEST 1. Unplug the power cord and short the two prongs of the plug with a jumper wire. 2. Turn on the power switch. 3. Measure the resistance value with ohmmeter between the jumpers AC plug and each exposed metal cabinet part, such as

screw threads, control shafts, handle brackets, etc.Note:

Some exposed parts may be isolated from the chassis by design. These will read infinity. 4. If the measurement is outside the specified limits, there is a possibility of shock hazard. The equipment should be repaired and

rechecked before it is returned to the customer.

3.3. BATTERY CAUTION 1. Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the

manufacturer. Dispose of used batteries according to the manufacturers Instructions. 2. The lithium battery is a critical component (type No.CR23541). Please observe for the proper polarity and the exact location

when replacing it and soldering the replacement lithium battery in.

15.1. PREPARATION

PbF (: Pb free) Solder

Soldering Iron

Tip Temperature of 700F 20F (370C 10C)Note: We recommend a 30 to 40 Watt soldering iron. Anexpert may be able to use a 60 to 80 Watt iron wheresomeone with less experience could overheat and damagethe PCB foil.

Flux

Recommended Flux: Specific Gravity 0.82.Type RMA (lower residue, non-cleaning type)Note: See ABOUT LEAD FREE SOLDER (PbF: Pb free)(P.4).

15.2. REMOVAL PROCEDURE 1. Put plenty of solder on the IC pins so that the pins can be

completely covered.Note:

If the IC pins are not soldered enough, you may givepressure to the P.C. board when cutting the pins with acutter.

2. Make a few cuts into the joint (between the IC and its pins)first and then cut off the pins thoroughly.

3. While the solder melts, remove it together with the IC pins.

When you attach a new IC to the board, remove all solderleft on the land with some tools like a soldering wire. If some

solder is left at the joint on the board, the new IC will not beattached properly.

15.3. INSTALLATION PROCEDURE 1. Tack the flat pack IC to the PCB by temporarily soldering

two diagonally opposite pins in the correct positions on thePCB.

Be certain each pin is located over thecorrect pad on the PCB.

2. Apply flux to all of the pins on the IC.

3. Being careful to not unsolder the tack points, slide thesoldering iron along the tips of the pins while feedingenough solder to the tip so that it flows under the pins asthey are heated.

15.4. REMOVING SOLDER FROMBETWEEN PINS

1. Add a small amount of solder to the bridged pins. 2. With a hot iron, use a sweeping motion along the flat part of

the pin to draw the solder from between the adjacent pads.

15 HOW TO REPLACE A FLAT PACKAGE ICEven if you do not have the special tools (for example, a spot heater) to remove the Flat IC, with some solder (large amount),a soldering iron and a cutter knife, you can easily remove the ICs that have more than 100 pins.
