Dab tsi yog Cov Ntsiab Cai ntawm Kev Xaiv Wave Soldering?

Flux spraying system

Selective yoj soldering tshuabflux spraying system yog siv rau kev xaiv soldering, piv txwv li cov flux nozzle khiav mus rau qhov chaw xaiv raws li cov lus qhia ua ntej thiab tom qab ntawd tsuas yog fluxes thaj tsam ntawm lub rooj tsavxwm uas yuav tsum tau soldered (qhov chaw txau thiab kab tsuag muaj), thiab tus nqi ntawm cov tshuaj tsuag hauv ntau qhov chaw tuaj yeem hloov kho raws li qhov kev zov me nyuam.Vim yog xaiv cov tshuaj tsuag, tsis yog tsuas yog cov nyiaj tau txais txiaj ntsig zoo piv rau yoj soldering, tab sis kev ua qias tuaj ntawm qhov chaw uas tsis yog soldering ntawm lub rooj tsavxwm kuj raug zam.

Txij li thaum nws yog xaiv cov tshuaj tsuag, qhov tseeb ntawm cov flux nozzle tswj yog siab heev (xws li lub flux nozzle tsav txoj kev), thiab lub flux nozzle yuav tsum muaj ib tug tsis siv neeg calibration muaj nuj nqi.

Tsis tas li ntawd, kev xaiv cov ntaub ntawv nyob rau hauv lub flux spraying system yuav tsum muaj peev xwm coj mus rau hauv tus account lub muaj zog corrosion ntawm non-VOC flux (ie, dej-soluble flux), yog li ntawd nyob qhov twg muaj ib tug muaj peev xwm ntawm kev sib cuag nrog flux, qhov chaw. yuav tsum muaj peev xwm tiv taus corrosion.

 

Preheat Module

Tus yuam sij rau preheat module yog kev nyab xeeb thiab kev ntseeg tau.

Ua ntej tshaj plaws, tag nrho-board preheating yog ib qho ntawm cov yuam sij.Vim tias tag nrho lub rooj tsavxwm preheating tuaj yeem tiv thaiv kom tsis txhob deformation ntawm lub rooj tsavxwm Circuit Court los ntawm cov cua kub tsis sib xws hauv ntau qhov chaw ntawm lub rooj tsavxwm.

Qhov thib ob, kev nyab xeeb thiab kev tswj hwm ntawm preheating yog qhov tseem ceeb heev.Lub luag haujlwm tseem ceeb ntawm preheating yog qhib lub flux, vim hais tias qhov ua kom cov flux ua tiav nyob rau hauv ib qho kev ntsuas kub, qhov kub thiab txias dhau los tsis zoo rau kev ua kom cov flux.Tsis tas li ntawd, cov khoom siv thermal ntawm lub rooj tsav xwm Circuit Court kuj yuav tsum tau tswj qhov kub thiab txias, lossis cov khoom siv thermal yuav raug puas tsuaj.

Cov kev ntsuam xyuas tau pom tias kev ua kom zoo txaus tuaj yeem ua rau lub sij hawm luv luv thiab txo qhov kub thiab txias;thiab txoj kev no, lub ncoo thiab substrate stripping, thermal poob siab rau lub rooj tsavxwm Circuit Court, thiab qhov kev pheej hmoo ntawm molten tooj liab kuj txo, thiab kev ntseeg siab ntawm cov soldering yog ib txwm muaj ntau ntxiv.

 

Solder Module

Lub soldering module feem ntau muaj xws li lub tog raj kheej tin, mechanical / electromagnetic twj, soldering nozzle, nitrogen tiv thaiv ntaus ntawv, thiab kis tau tus mob.Vim lub tshuab hluav taws xob / hluav taws xob twj tso kua mis, lub tshuab hluav taws xob hauv lub tog raj kheej yuav txuas ntxiv tawm ntawm qhov sib cais nozzles los tsim ib qho chaw ruaj khov tin yoj;cov cuab yeej tiv thaiv nitrogen tuaj yeem tiv thaiv kom tsis txhob muaj cov nozzles los ntawm kev txhaws vim muaj kev puas tsuaj;thiab cov cuab yeej kis tau tus mob kom paub meej qhov kev txav ntawm lub tog raj kheej lossis lub rooj tsav xwm Circuit Court kom ua tiav qhov point-by-point soldering.

1. Kev siv cov roj nitrogen.Kev siv cov roj nitrogen tuaj yeem ua rau kom muaj kev sib tw ntawm cov hlau lead-dawb solder los ntawm 4 zaug, uas yog qhov tseem ceeb heev rau kev txhim kho tag nrho ntawm qhov zoo ntawm cov hlau tsis muaj hlau.

2. Qhov sib txawv ntawm kev xaiv soldering thiab dip soldering.Dip soldering yog dip lub Circuit Court board nyob rau hauv lub tin lub tog raj kheej cia siab rau lub nto nro ntawm lub solder ntuj nce mus ua kom tiav cov solder.Rau qhov muaj peev xwm kub kub thiab ntau txheej hauv Circuit Court boards, dip soldering yog ib qho nyuaj rau ua tiav cov tin nkag mus rau cov kev cai.Selective soldering yog txawv, raws li cov dynamic tin nthwv dej rushing tawm ntawm lub soldering nozzle ncaj qha cuam tshuam rau ntsug tin nkag mus rau hauv lub los ntawm lub qhov;tshwj xeeb tshaj yog rau cov hlau lead-free soldering, uas yuav tsum tau ib tug dynamic thiab muaj zog tin nthwv dej vim nws cov khoom tsis zoo wetting.Tsis tas li ntawd, lub zog ntws yoj tsis tshua muaj oxide residue rau nws, uas tseem yuav pab txhim kho cov khoom zoo.

3. Kev teeb tsa ntawm cov khoom siv soldering.

Rau qhov sib txawv ntawm cov pob qij txha sib txawv, cov qauv sib txawv yuav tsum muaj peev xwm ua rau ib tus neeg teeb tsa rau lub sijhawm soldering, yoj lub taub hau qhov siab thiab txoj haujlwm soldering, uas yuav ua rau tus kws ua haujlwm ua haujlwm txaus los hloov cov txheej txheem kom txhua qhov sib koom ua ke tuaj yeem ua tau zoo.Qee cov cuab yeej xaiv cov khoom siv txawm tias muaj peev xwm tiv thaiv kev sib txuas los ntawm kev tswj cov duab ntawm qhov sib koom ua ke.

 

PCB thauj system

Qhov tseem ceeb ntawm kev xaiv soldering rau lub rooj tsavxwm hloov chaw yog qhov tseeb.Txhawm rau kom ua tiav qhov tseeb, kev hloov pauv yuav tsum ua raws li ob lub ntsiab lus hauv qab no.

1. cov khoom siv yog deformation-pov thawj, ruaj khov thiab ruaj khov.

2. Muab cov cuab yeej tso rau hauv cov kab uas hla dhau los ntawm flux spray module thiab solder module.

Cov nqi khiav qis vim xaiv vuam

Cov nqi khiav lag luam qis ntawm kev xaiv vuam yog qhov laj thawj tseem ceeb rau nws qhov nrov nrov nrog cov tuam ntxhab.
