This manual is structured to enable a technician with no

previous knowledge of the system, to become familiar with

the operation and maintenance of the equipment. The

safety section of the manual explains the inherent dangers

presented by any type of desoldering/soldering equipment

and warnings to minimize the risk of injury through igno

rance.

TECHNICAL DESCRIPTION

Infra RedLamp



The200WattInfraRed(I.R.)lampislocatedinthel amphousing

at the  front end of the hand unit. The lamp emits mostly short

waveI.R.radiationatapproximately1.0micronwavelength.



TopHeat



Thetopheataddsheattotheprocessandbringsthesolderjoint

temperature up to reflow. The heating process of the Focused

Infrared Welding system is a combination of the Solderlight gun

andthe Preheater.ThePreheater heatsthePCB,pads,andleads

of  the  component  up  to  120140° C  and  the  Solderlight  gun

increasesthetemperaturefurtheruntilyoureachreflow.



WhatSolderlightguntemperatureshouldyouuse?



Between180380°C.Onlyi ncreasetheguntemperature afteryou

haveincreasedthePreheatertotherequiredtemperature.Always

preheat the  PCB (between 30 90 seconds) to allow the heat to

conduct through the component before applying the Solderlight

gun.



What's the working distanceoftheSolderlight gun and how do I

moveitforrework?



Approximately 510mm when reworking and move up to 30mm

when removing  Component  move the hand tool in a scanning

motiontoheatleads,takingaboutonesecondforeachscanofthe

TECHNICAL DESCRIPTION

Continuation

Preheater



The Preheater's function is to preheat the PCB and component;

thisprotects thePCB fromdelaminating andthe compone ntfrom

thermalshock.ThePreheater alsoequalizestheconductiveeffect

ofthegroundplaneofthePCB.

The ceramic heater preheats  the PCB  and  the  heat  conducts

throughthePCBandpreheatsthecomponent,sowhenyouapply

the Solderlight gun there is no chance of thermal  shock. The

balance of heat energy supplied should be approximately 75%

fromthePreheaterand25%fromtheSolderlightgun.



WhatBackHeatsettingshould youuse?



Generally180°Csetonthe Preheaterisagood startingpoint.If

theprocesstakeslongerthan180secondsthenincreasethePre

heaterby20°Cincrementstoreducetimetaken.Withthecorrect

PreheatersettingthetopofthePCBwillreachapproximately120

140°Cinabout60120seconds.



Whydoweneedthegoggles?


