1Starting and starting front inspects

Starting front inspects the infra-red lamp body, the temperature sensor and

the power line first whether connects good

Turns on the power switch.Self-checking uses (on kneading board display

monitor demonstrates for the previous use when setting value) again through after.

The front panel has two switches, controls the preheating chassis, the infra-

red lamp body work separately; Presses the front panel IR PRE-HEAT PIATE;

;, may 60-200 ; in, the adjustment preheating chassis preheating

temperature, presses the switch is ON;, then the preheating chassis starts to work,

presses the switch is OFF;, then preheating chassis knock off; Presses the front

panel IR HEAT LAMP; ;may200-350 ; in, adjusts the infra-red lamp body

the operating temperature, presses the switch is ON;, then the infra-red lamp body

starts to work, presses the switch is OFF;,then infra-red lamp body knock off.

2Sealing off/repair operation1 PCB board laying aside

Will elect well the PCB board alignment carrier on notch, will lay aside on the

PCB board support, will fasten the PCB board carrier handwheel, fixed good PCB

board; About moves the carrier slide rails, selects the appropriate working position.

2 Before sealing off/repair adjustment and preparatory work

Adjusts the PCB board position, causes to need the sealing off/repair the chip

center vertical alignment infra-red lamp body facula center; The adjustment lamp

body altitude, maintains the lamp holder and the sealing off thing is highly 20-30mm

is suitable;

Lays aside the infra-red lamp the temperature sensor nearby the chip the

suitable position, all around spreads the welding flux in the chip with sensor (to weld

treasure or burnt oil), does this may cause the sensor to measure the temperature is

more accurate, simultaneously is helpful the solder to help welds the function, BGA

welds the plate to be able to be completer, can prevent effectively welds the plate to

stick and questions and so on tin wool.

When the chip spreads has the waterproof solid sealing compound, certainly

must first open the preheating chassis melt rubber, after lets rubber being heated

soften or the pulverization, cleans up first; Also available sol hydrosol and so on other

measures.According to sol temperature which the factory provides, carries on sol

processing, the melt rubber temperature is not suitable excessively high, generally

for 120-140 ; for suitable, preheat interval 3 - 5 minutes or longer.

3 Sealing off/repair process

According to product technological requirement or PCB board size, adjustment

preheating chassis preheating temperature 60-200; adjustable), may open the

preheating chassis ahead of time, one 3 - 5 minutes, the preheating chassis can

stabilize in the temperature range which supposes in advanceAccording to the chip size and the welding technological requirement, selects the

suitable infrared lamp the heating temperature 200-350 adjustable), can satisfy the

sealing off/repair technological requirement then.

The common experience is: According to the repair chip size, adjusts the infra-

red lamp suitably the output temperature 220; adjustable) and chassis preheating

temperature (60-200 ; adjustable);

When the sealing off/repair is smaller than the 20x20mm chip, may adjust the

infra-red lamp temperature to 220-240; about, if the chip has not spread the

waterproof solid sealing compound, or the PCB board is small cannot distort, but

does not operate the preheating chassis preheating; Otherwise first preheating 120-

140 degree is suitable;

Opens in a big way, when 30x30mm chip, according to the craft and the user

experience, may adjust the infra-red lamp 240-260; about, preheating chassis 140-

200 ;, first preheating 3 - 5 minutes, after and so on the chassis stable are

supposing in advance the temperature, may complete the sealing off/repair process

very conveniently; This time the infrared light is strongest, the chip elevates

temperature quickly, pays attention to the control specially, prevented the sensor

displacement, the temperature measurement does not permit, the chip being heated

time too is long, the elevation of temperature too is high, hot bad chip.The disassemblage operating process is generally: The fixed PCB board,

adjusts the PCB board the position, adjusts the chip which the infra-red lamp the

heartfelt alignment disassembles, adjusts the infra-red lamp, lays aside the infra-red

lamp highly the temperature sensor, spreads the welding flux, the hypothesis

preheating chassis preheating temperature and the infra-red lamp operating

temperature, the opening preheating chassis, after 3-5 minute or a longer spot,

preheating temperature control nearby the setting value, the opening infra-red lamp

heating chip, achieved supposes the temperature or the chip tin plate in advance

melts, takes down the chip after the real suction pen or the tweezers, closes the

infra-red lamp and the pre-heating platen switch, and so on main engine full cooling,

closes the power source.

Returns to the operating process which welds is generally: Operating

process basically with disassemblage process.The similarity is: Cleans up first welds

the plate and plants the tin ball, the preheating PCB board, the correct laying aside

chip, the craft temperature which returns according to the tin ball welds carries on,

the backflow welding, cooling preheating.

May again enhance temperature 20-30 degree regarding the non-lead solder

component

4 In the sealing off/repair process matters needing attention and the

correlation showed that,

When sealing off/repair quite big PCB board chip, for instance: The computer

board, must certainly carry on the imposite fully the preheating seasoning, may the

technological requirement which provides according to the factory carry on, also may

depend on the experience to process; Only then processes appropriately, can

prevent effectively when sealing off/repair chip, the PCB board distortion and

produces from this faulty soldered joint, chip rake.In the sealing off/repair process, the infra-red lamp shines in the region, all

plastic plug-in unit, carries on the cover using the aluminum tin foil, prevented high

temperature infrared dries the distortion or the harm.But is not wraps completely.

Returns to PCB board which welds/repairs, after and so on cooling, after cleans

first, dryly, carries on the test; If is not good, may again return welds.Again not good

repetition entire process.

Around the work, on according to has not put the PCB board in the situation,

may not the long time opening infra-red lamp, be able to reduce the lamp the service

life; Forbid strictlys shining the counter-optical very strong reflection with the infra-red

lamp long time, can affect the lamp seriously the life.

3Maintenance and overhaul

1 Complete machine maintenance:

After the machine uses period of time, to the focusing frame, the guide pillar, the

PCB board support and so on the slipper, regularly with fat cleaning, the

maintenance lubricates and guards against rust the goal.

2 Preheating chassis and infra-red lamp body maintenance:

The preheating chassis and the infra-red lamp body, specially the infra-red lamp

high insightful protection slide, regularly with dehydrated alcohol cleaning, the

elimination welding flux condensate, maintains the infrared hot radiationunobstructed.

3 Infra-red lamp replacement:

When replaces the infra-red lamp, with the special-purpose inside caliper gauge or

the long mouth pliers, will fix the slide first the spring inside caliper, the slide, spring

inside caliper one time takes down; Again takes down the fixed infra-red lamp the

spring inside caliper, then with the bamboo slip or the wooden bat outside lamp

chimney air vent place, goes against the infra-red lamp gently, draws out the lamp

holder to replace the new infra-red lamp; Installs again according to the opposite

order then.

Matters needing attention

1Matters needing attention: After the work finished, do not have to turn off light

immediately the source, causes the ventilator full cooling lamp body, the extension

service life.2The maintenance vent ventilates unimpededly, the lamp body is pure.Uses the

dehydrated alcohol clean lamp holder slide regularly!

3The guide pillar, the focusing support at the right moment uses the fat to clean,

maintenance lubrication.

4Careful, high temperature operation, attention security.

5Long-time does not use, should cramp out the power source plug!

The maintenance pledged that

The complete machine maintains for a year, the lifelong service.Infra-red lamp

design life 1000 hours, guaranteed usable three months, long-term factory price

supply fitting.Provides the immediate network online Q/A and the technical advisory

work service.
