1. Flux spraying system
Selective yoj soldering txais ib qho kev xaiv flux spraying system, uas yog, tom qab lub flux nozzle khiav mus rau txoj hauj lwm raws li lub programmed cov lus qhia, tsuas yog lub cheeb tsam ntawm lub Circuit Court board uas yuav tsum tau soldered yog sprayed nrog flux (point tshuaj tsuag thiab kab tsuag. muaj), Cov tshuaj tsuag ntim ntawm ntau qhov chaw tuaj yeem hloov kho raws li qhov kev pab cuam.Vim tias nws yog kev xaiv tshuaj tsuag, tsis yog tsuas yog tus nqi ntawm cov flux tau txais kev cawmdim heev piv nrog yoj soldering, tab sis nws kuj zam cov pa phem ntawm qhov chaw uas tsis yog soldering ntawm lub rooj tsavxwm.
Vim hais tias nws yog xaiv cov tshuaj tsuag, qhov precision ntawm kev tswj ntawm lub flux nozzle yog siab heev (nrog rau txoj kev tsav tsheb ntawm lub flux nozzle), thiab lub flux nozzle yuav tsum muaj ib tug tsis siv neeg calibration muaj nuj nqi.Tsis tas li ntawd, nyob rau hauv lub flux spraying system, cov khoom xaiv yuav tsum coj mus rau hauv tus account lub zog corrosiveness ntawm non-VOC fluxes (xws li dej-soluble fluxes).Yog li ntawd, nyob qhov twg muaj kev sib cuag nrog flux, qhov chaw yuav tsum muaj peev xwm tiv taus corrosion.
2. Preheating module
Preheating ntawm tag nrho lub rooj tsavxwm yog tus yuam sij.Vim tias tag nrho lub rooj tsavxwm preheating tuaj yeem tiv thaiv cov haujlwm sib txawv ntawm lub rooj tsavxwm Circuit Court los ntawm kev ua kom sov tsis sib xws thiab ua rau lub rooj tsavxwm Circuit Court deform.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.Txij li thaum qhov ua kom cov flux ua tiav nyob rau hauv ib qho kev ntsuas kub, ob qho tib si siab dhau thiab qis dhau yog qhov ua rau muaj kev cuam tshuam 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 tau qhov kub thiab txias, txwv tsis pub cov khoom siv thermal yuav raug puas tsuaj.
Cov kev sim qhia tau hais tias txaus preheating tuaj yeem txo lub sijhawm vuam thiab txo qhov vuam kub;thiab nyob rau hauv no txoj kev, lub tev ntawm lub ncoo thiab lub substrate, lub thermal poob siab rau lub Circuit Court board, thiab cov kev pheej hmoo ntawm melting tooj liab kuj raug txo, thiab kev cia siab ntawm lub vuam yog ib txwm txo.nce.
3. Vuam module
Lub vuam module feem ntau muaj tin lub tog raj kheej, txhua yam / electromagnetic twj tso kua mis, vuam nozzle, nitrogen tiv thaiv ntaus ntawv thiab kis tau tus mob.Vim yog qhov kev txiav txim ntawm lub tshuab hluav taws xob / hluav taws xob twj tso kua mis, cov khoom siv nyob rau hauv lub tin tank yuav txuas ntxiv mus tawm ntawm qhov ntsug vuam nozzle, ua kom ruaj khov tin yoj;cov cuab yeej tiv thaiv nitrogen tuaj yeem tiv thaiv qhov vuam nozzle los ntawm kev thaiv vim yog lub cim ntawm tin slag;thiab cov khoom siv kis tau tus mob Qhov tseeb txav ntawm lub tin lub tog raj kheej los yog lub rooj tsav xwm Circuit Court yog ua kom paub tseeb point-by-point vuam.
1. Kev siv cov nitrogen.Kev siv cov nitrogen tuaj yeem ua rau kom muaj kev sib tw ntawm cov hlau lead los ntawm 4 zaug, uas yog qhov tseem ceeb heev rau kev txhim kho tag nrho ntawm cov hlau lead zoo.
2. Qhov sib txawv ntawm kev xaiv soldering thiab dip soldering.Dip soldering yog muab tso rau hauv Circuit Court board nyob rau hauv lub tin tank thiab cia siab rau ntawm qhov nro ntawm lub solder kom ib txwm nce mus ua kom tiav cov soldering.Rau lub peev xwm loj kub thiab ntau lub rooj sib tham, nws yog ib qho nyuaj rau dip soldering kom tau raws li qhov yuav tsum tau ua ntawm tin nkag.Kev xaiv ntawm soldering yog txawv.Lub dynamic tin nthwv dej yog xuas nrig ntaus tawm ntawm lub nozzle, thiab nws lub zog dynamic yuav ncaj qha cuam tshuam rau txoj kab ntsug tin nkag mus rau hauv lub qhov los ntawm qhov;tshwj xeeb tshaj yog rau cov hlau lead soldering, vim nws tsis zoo wettability, nws xav tau dynamic Strong tin yoj.Tsis tas li ntawd, oxides tsis zoo li yuav nyob twj ywm rau ntawm cov dej ntws muaj zog, uas tseem yuav pab txhim kho vuam zoo.
3. Kev teeb tsa ntawm vuam tsis.
Rau qhov sib txawv vuam cov ntsiab lus, cov vuam module yuav tsum muaj peev xwm ua tus kheej lub sijhawm vuam, yoj qhov siab thiab vuam txoj haujlwm, uas yuav ua rau tus kws ua haujlwm ua haujlwm txaus los kho cov txheej txheem, kom qhov vuam cuam tshuam ntawm txhua qhov vuam taw tes tuaj yeem ua tiav..Qee cov khoom siv vuam xaiv tuaj yeem ua tiav cov txiaj ntsig ntawm kev tiv thaiv kev sib txuas los ntawm kev tswj cov duab ntawm cov pob qij txha.
4. Circuit board kis tau tus mob
Qhov tseem ceeb ntawm kev xaiv soldering rau Circuit Court board kis tau tus mob yog qhov tseeb.Yuav kom ua tau raws li qhov yuav tsum tau ua, cov kab ke sib kis yuav tsum ua tau raws li ob lub ntsiab lus hauv qab no:
1. Cov khoom siv yog los tiv thaiv deformation, ruaj khov thiab ruaj khov;
2. Nruab ib lub cuab yeej muab tso rau ntawm txoj kev los ntawm cov flux spraying module thiab vuam module.Tus nqi qis ua haujlwm ntawm kev xaiv vuam yog ib qho tseem ceeb vim li cas nws tau txais tos sai sai los ntawm cov tuam ntxhab.
