OPERATING PROCEDURES
6. To view the actual temperature read by the three external temperature
sensor,repeatedlypresstheselectionbuttonuntilthetopdisplayshowsthe
top heater external temperature probe's (probe A) actual temperature
followedbyasuffix“A”.Themiddledisplaywillshowexternaltemperature
probe b’sactualmeasuredtemperaturefollowedbya suffix“b”. Andthe
bottomdisplaywouldshowtheactualmeasuredtemperatureoftheexternal
temperatureprobeC.Itisfollowedbyasuffix“c”.
Note:Undertype“1”modeofoperationitisnotnecessarytomonitorthe
internaltemperaturesensor’sreadout. i.e.internaltemperaturereadouts
withsuffix“d”and“E”. 
External temperature probes are labeled.  Top heater external
probeis labeledA,whiletheothertwois labeledbandC.Thedisplayed
actualtemperaturereading’ssuffixcorrespondstothelabels.
F.TYPE“2”OPERATION
Before proceeding with this type of operation, attach the top external
temperatureprobe A toonecorneroftheBGAorICtobereworked.Thenattach
theexternaltemperatureprobe b totheundersideofthePCBtobeworkedon,
preferablytothesideandnotdirectlyundertheBGAorICtobereworkedon.The
externaltemperatureprobeCcanbeplacednearanyareaofinterest.
Thistypeofoperationutilizestheexternaltemperatureprobe A toregulatethe
top heater, while the external temperature probe b regulates the heat of the
bottom heater. The  external temperature probe C can be used for additional
monitoring.
Inprofilemodethefirst3segmentsutilizesthebottomheatertoreach75%of
the required heat for reflow. After which the bottom heater would regulate the
boardatthetemperaturesetat segment3.Thenthelast three segmentsutilizes
thetopheatertoprovidethefinal25%oftheheattoreachreflow.

FUNCTIONS and FEATURES
● MultiPointBoardHolder
— Innovative board holder: Nine securing screws with four side grips to
provideasecurefitforvariousboardsizesandshapes.Effectivelyminimizes
BGAballsshortingtogetherduetoboardwarping.
● MultiAxisArmature
— Top heater’s support allows 3 degrees of freedom:  Rotation of the Top
heater, Swiveling of the armature, andsliding adjustments. This new design
expandstheeffectiveworkingcoverageoftheunit,allowingustoaccesseven
thoseICsattheedgeorcornerofthePCBs.
● DigitalSystemControlandSafety
— CPU controlled system with easy to use digital controls and display. Uses
advanceddigitalcontrolsandsignalprocessingformaximumperformance,and
accuracy. Builtin overheat protection and temperature limiting. The system
automaticallylimitstheriseintemperaturetoindustrystandard3degreesper
second.Thiswillminimizedamagetosensitivecomponentsandensureproper
reflow.
● Profilemodewithautoadjustment
—Threeprogrammable6segmentreworkingprofile.Setandstorethedesired
duration andtemperatureto ensurehigh success rate for repetitive reworks.
Equippedwithautoprofileadjustment,systemautoeditsyourprofiletoensure
profilemeetsindustrystandardlimits.
● TheIntegratedSolderIronhasexcellentthermalrecoveryspecificallydesigned
fortheleadfreesolderingprocess.Ithasawiderangeoftipssizesandstyles
designedtofitdifferentrequirements.SelecttunneltypewhencleaningBGAs,
use the blade type for drag soldering, conical types for normal thruhole
solderingandmanymoredifferenttipsizeandstyles.
● WideCompatibility
—TheentiresystemiscompatiblewithLeadfreesolder,isRoHS,CEandESD
Safecompliant.
