1. Precautions
1-1 Safeguards
Please read these instructions carefully and completely.
1. Unplug this product from the wall outlet before you disassemble it.
2. Replace defective parts with the same parts as them.
3. Check the insulation of electricity-conducting parts (metal plate or input terminal) that can easi­ly contact AC plug blades.
4. How to check insulation: Pull the AC plug out of the outlet and measure insulation resistance of each blade.
5. Insulation resistance of AC plug blades against electricity-conducting parts should be 1 megaohm or over.
6. Always use it after connecting the ground of mea­suring instruments to the ground of chassis. And after you use it, separate the ground of the measuring instruments lastly.
1. Do not use this product in a humid place nor out­door.
2. Do not place this product on an unstable stand or table. The product may fall, causing serious dam­age to the product.
3. Use this product in a well-ventilated place.
4. Slots are provided for ventilation. Never push objects of any kind into this product through these slots as they may result in a fire or electric shock. Never spill liquid of any kind on the prod­uct.
5. Power-supply cords should be routed so that they are not likely to be walked.
6. Use this product in a place big enough to support printers.
7. Install this product within 180cm from the com­puter and 150cm from the power outlet.
8. This product should be operated only from the type of power source indicated on the marking label.
9. If you use extension cords, be sure they have three-wire grounding-type power outlets. Do not overload wall outlets and extension cords. Never load one wall outlet with over 15 ampere.
10. Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a dry cloth for cleaning.
11. Use only standard paper, OHP film, andap­proved envelopes.
1-2 Servicing Precautions
Please read these instructions carefully and completely.
1-2 Samsung Electronics
1-3 Static Electricity Precautions
Semi-conductors are easily damaged by static elec­tricity. They are usually called electrostatically sensitive devices (ESD). For example, there are IC, FET, and semi-conductor chips.
1) Before you handle semi-conductor parts, be sure to discharge electricity by touching earth connec­tion or putting on a wristband. (Before you turn on the product, put off the wristband to prevent electric shock.)
2) Remove the static electricity protective device and then place the assembly on the surface of electric conductors such as aluminum foil to prevent static electricity from accumulating.
3) Do not use chemicals like Freon. These chemicals produce static electricity that may damage parts.
4) Solder ESD parts with a grounded soldering iron.
5) Use static electricity protective solder. Solder not marked Ôstatic electricity protectiveÕ may accu­mulate static electricity that damages ESD parts.
6) Do not get rid of the static electricity protective cover of ESD parts until you are ready to replace them. Most of ESD parts are packed, with elec­tricity conducting materials in contact with ESD parts leads.
7) Make static electricity protective materials con­tact the chassis or the circuit where parts will be mounted, before you remove the materials from ESD parts to be replaced.
8) Minimize your motion when you handle the ESD parts from which static electricity protective materials have been removed. Static electricity is generated when your clothes are frictionized or you walk on the carpet.
9) Be careful not to bend pins when you handle IC.
10) Pay attention to directions when you mount parts on PCB.
11) Overheat during soldering may damage the parts completely. Heat affects all the parts.

2-3 Chip Replacement (SMD parts)
2-2-1. Precautions for Chip Replacement
1. See to it that the soldering iron does not touch parts directly. In particular, TSOP may be easily damaged by heat.
2. Handle the soldering iron with care and avoid using the same many times. Some parts can be damaged by sudden heat. Preheat parts for min­utes at about 100¡c before soldering them.
3. The temperature of the soldering iron should remain at about 240¡c Use a 280¡c iron for bigger parts.
4. Thin (0.3mm) solder used for chip parts does not contain enough flux. Use additional flux.
* For computers and OA systems, water-soluble flux
is used. Water-soluble flux and solder are also good for replacing parts and repairing this prod­uct. Improper flux may corrode the soldered part and cause serious defects to the system.
5. Be careful not to damage the circuit pattern when you disjoin soldering. The pattern should be clean because there are a lot of pins close together on IC.
6. Be careful not to cause a short circuit between close pins.
7. Locate parts in place. It has a great influence on soldering.
8. Do not use repaired parts again.
9. Check the soldered part.
10. Defective variable resistors are not adjustable. Be sure to replace them.
11. After finishing the job, check if there are cold sol­dered parts.
2-2-2. Tools to Replace Chips
The following tools are used to replace chip parts.
¥ iron with thin tip ¥ iron with small and flat tip ¥ solder remover ¥ ventilation device ¥ tools to lift flat parts ¥ flux that can be cleaned with water ¥ 0.3mm thin solder that can be cleaned with water ¥ wire to remove solder ¥ tweezers
2-2-3. Chip Resistance & Chip Condenser
2-2-3 (a) Type There are the following types of chip resistance and chip condensers.
¥ There are the following types of thin film and chip
condensers. ¥ Carbon Film chip resistance ¥ Metal Film chip resistance ¥ Chip ceramic condenser ¥ Chip variable resistance
2-2-3 (b) Removal Use 2 soldering irons. a. Use a thin-tip iron. b. Keep about 280¡c c. Apply heat to both ends of a part at the same time. d. Remove it with the tip of the iron while heating. e. Remove the remaining solder on PCB completely
with solder removing wire. It should be done to install a new part.
Samsung Electronics 2-9
2-2-3 (c) Installation a. Clean the place where a new part will be located. b. Apply water-soluble flux. c. Set a part correctly in place. Prevent it from shift-
ing.
d. Stick the part fast without contacting it directly
with the soldering iron. Put 0.3mm solder between the iron and the part so that it can melt into the part.
e. Check the soldered part with a magnifier.
2-2-4. Chip Tantalum Condenser and Chip Filter
2-2-4 (a) Type There are the following types of chip tantalum con­denser and chip filter. ¥ Chip coil ¥ Chip tantalum condenser ¥ Chip tantalum electrolysis condenser ¥ Chip aluminum electrolysis condenser ¥ Chip transformer ¥ Chip filter
2-2-4 (b) Remoral
1. Use a special solder-removing iron. a. Choose an iron tip that suits the size of the part. b. Put the iron tip to the part to be soldered. c. Remove the part when solder melts. d. Remove the remaining solder completely with
solder-removing wire.
2. Use two irons. a. Use an iron with small flat tip. b. Apply heat to both ends of the part at the same
time.
c. Remove the part with the tip of the iron while
melting.
d. Remove the remaining solder completely with
solder removing wire.
2-2-4 (c) Installation
1. Clean the place where new parts will be installed.
2. Apply water-soluble flux.
3. Locate a part exactly in place. Be careful not to shift it.
4. Stick the part fast with a soldering iron not con­tacting it directly. Put 0.3mm solder between the iron and the part so that it can melt into the part.
5. Check the soldered part with a magnifier.
2-2-5. Chip Variable Resistance, Chip
Variable Condenser, Diode & Transistor
Chip Variable Resistance, Chip Variable Condenser, Diode & Transistor
