1 Safety Precautions

1.1. General Guidelines

1. When servicing, observe the original lead dress. If a sh ort circuit is found, replace all parts which have been overheated or damaged by the short circuit.

2. After servicing, see to it that all the protective devices such as insulation barri ers, insulation papers shields are properly installed.

3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.

1.2. Touch-Current Check

1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.

2. Connect a measuring network for touch currents between each expo sed metallic part on the set and a good earth ground such as a water pipe as shown in Figure 1.

3. Use the Leakage Current Tester (Simps on 228 or equivalent) to measure the potential across the measuring network.

4. Check each exposed metallic part and measure the voltage at each point.

5. The potential at any point (touch current) expressed as voltage U For AC: U1 = 35 V (peak) and U2 = 0.35 V (peak); For DC: U

NOTE :

The limit value of U DC.

The limit value U

= 1.0 V,

= 0.35 V (peak) for AC and U1 = 1.0 V for DC correspond to the values 0.7 mA (peak) AC and 2.0 mA

= 35 V (peak) for AC correspond to the value 70 mA (peak) AC for frequencies greater than 100 kHz.

and U2, do not exceed the following values:

6. Should a measurement be out of the li mits specified, there is a possibility of a shock hazard , and the equipment should be repaired and rechecked before it is returned to the customer.

2 Prevention of Electro Static Discharge (ESD) to

Electrostatically Sensitive (ES) Devices

Some semiconductor (solid state) devices can be damaged easi ly by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and s ome fieldeffect transistors and semiconductor “chip” components. The following techniques should be used to help reduce the incidence of component damage caused by electro static discharge (ESD).

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should be removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminium foil to prevent electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static (ESD protected)” can generate electrical charges sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate el ectrical charges sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediate ly before you a re ready to install it (most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminium foil or comparable conductive material).

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed.

Caution:

Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ES devices (otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can gen erate static electricity (ESD) sufficient to damage an ES device).

3 About Lead Free Solder (PbF)

Note: Lead is listed as (Pb) in the periodic table o f elements. In the information below, Pb will refer to Lead Solder and PbF will refer to Lead Free Solder. The Lead Free Solder (PbF) used in our manufacturing proce ss and discussed below is (Sn+Ag+Cu). Those are Tin (Sn), Silver (Ag) and Copper (Cu), although other types are available.

This model uses PbF in its manufacture due to environmental conservation issues. For service and repair work, we would suggest the use of PbF as well, although Pb may be used.

PCBs manufactured using lead-free will have the “PbF within a leaf Symbol” stamped on their back.

Caution

• PbF has a higher melting point than that of standard solder. Typi cally the melting point is 50 ~ 70°F (30~40 °C) higher. Please use a high temperature soldering iron and set it to 700 ± 20°F (370 ± 10°C).

• PbF will tend to splash when heated too high (about 1100°F or 600°C). If you must use Pb solder, please completely remove all of the PbF on the pins or solder area before applying Pb. If this is no t practical, be sure to heat the PbF until it melts, before applying Pb.

• After applying PbF to double layered boards, please check the component side for excess solder which may flow onto the opposite side (see Figure 2).

Figure 2

Suggested PbF

There are several kinds of PbF available for purchase. This product uses Sn+Ag+C u (tin, silver, copper) solder. However, Sn+Cu (tin, copper) and Sn+Zn+Bi (tin, zinc, bismuth) solders can also be used.
