Safety Precautions

1-1. Repair Precaution

― Repair in Shield Box, during detailed tuning.

Take specially care of tuning or test,

because specipicty of cellular phone is sensitive for surrounding interference(RF noise).

― Be careful to use a kind of magnetic object or tool,

because performance of parts is damaged by the influence of magnetic force.

― Surely use a standard screwdriver when you disassemble this product,

otherwise screw will be worn away.

― Use a thicken twisted wire when you measure level.

A thicken twisted wire has low resistance, therefore error of measurement is few.

― Repair after separate Test Pack and Set because for short danger (for example an

overcurrent and furious flames of parts etc) when you repair board in condition of

connecting Test Pack and tuning on.

― Take specially care of soldering, because Land of PCB is small and weak in heat.

― Surely tune on/off while using AC power plug, because a repair of battery charger is

dangerous when tuning ON/OFF PBA and Connector after disassembling charger.

― Don't use as you pleases after change other material than replacement registered on SEC System.

Otherwise engineer in charge isn't charged with problem that you don't keep this rules.

afety Precautions

1-2. ESD(Electrostatically Sensitive Devices) Precaution

Several semiconductor may be damaged easily by static electricity. Such parts are called by ESD

(Electrostatically Sensitive Devices), for example IC,BGA chip etc. Read Precaution below.

You can prevent from ESD damage by static electricity.

― Remove static electricity remained your body before you touch semiconductor or parts with

semiconductor. There are ways that you touch an earthed place or wear static electricity

prevention string on wrist.

― Use earthed soldering steel when you connect or disconnect ESD.

― Use soldering removing tool to break static electricity. , otherwise ESD will be damaged by

static electricity.

― Don't unpack until you set up ESD on product. Because most of ESD are packed by box and

aluminum

plate to have conductive power,they are prevented from static electricity.

― You must maintain electric contact between ESD and place due to be set up until ESD is

connected

completely to the proper place or a circuit board.

LCD F-PCB KIT Assembly

1) At attaching, align two FPCB HOLEs and two silk

points.

2) Attach and start the soldering.

※ Caution : At soldering, be careful about

getting loose and recheck alignment of silk

points and pads.

1) At LCD backside, detach the release paper of the

both-sided tape

2) Like figure, attach the insulation tape at FPCB

backside. - Using cotton stick, rub down the

insulation tape to be tight.

1) Align the right side EL FPCB and PBA Land and

start the soldering..

1) Assemble the LCD hook.

※ Caution

※ Caution Then, be careful about "short" of the

soldering part.

First, assemble the left downside and then

assemble the right upside.

1) After soldering, attach the insulation tape along

the silk line.

- Using cotton stick, rub down the folded part not

to get loose.

1) Wrap up and attach the left side insulation

tape to the PBA backside.(like figure)

※ caution : Recheck attaching part not to get

loose.

※ caution

Be careful about "short"

of soldering part.

Recheck attaching part not to get loose.
