Kev kho ntawmxaiv yoj soldering tshuab
Rau cov khoom siv xaiv yoj soldering, feem ntau muaj peb qhov kev saib xyuas: flux spraying module, preheating module, thiab soldering module.
1. Flux spraying module tu thiab tu
Flux spraying yog xaiv rau txhua qhov sib koom ua ke, thiab kev saib xyuas kom zoo tuaj yeem ua kom nws txoj haujlwm ruaj khov thiab raug.Thaum lub sij hawm cov txheej txheem txau, feem ntau muaj me me ntawm flux tshuav ntawm lub nozzle, thiab nws cov kuab tshuaj yuav evaporate thiab tsim condensation.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ntxuav lub nozzle thiab thaj chaw ib puag ncig nrog cov ntaub ntawv tsis muaj plua plav dipped hauv cawv lossis lwm yam kev daws teeb meem ua ntej txhua qhov kev tsim khoom pib tshem cov flux residue ntawm lub nozzle kom tsis txhob lub nozzle raug thaiv thiab ua rau cov txheej txheem tsis zoo. thawj ob peb lub rooj tsavxwm hauv kev tsim khoom tas mus li.
Kev saib xyuas tag nrho ntawm lub nozzle yuav tsum tau ua hauv peb qhov xwm txheej hauv qab no: kev ua haujlwm tsis tu ncua ntawm cov khoom siv mus txog 3000 teev;kev ua haujlwm tsis tu ncua ntawm cov cuab yeej siv rau ib xyoos;thiab txuas ntxiv ntawm kev tsim khoom tom qab ib lub lim tiam ntawm downtime.Kev saib xyuas zoo yuav tsum tau them sai sai rau kev tu sab hauv ntawm lub nozzle, thiab nws cov cuab yeej atomization yog qhov zoo tshaj plaws ntxuav siv ultrasonic tu.Ua ntej siv ultrasonic tu, cov tshuaj ntxuav yog rhuab mus txog 65 ° C, uas yuav txhim khu lub peev xwm decontamination.Nyob rau tib lub sijhawm, cov kav dej thiab sealing qhov chaw ntawm cov tshuaj txau yuav tsum tau kuaj xyuas kom zoo.
2. Kev saib xyuas ntawm lub preheating module
Txhua zaus ua ntej cov cuab yeej qhib thiab siv, lub preheating module yuav tsum tau kuaj xyuas seb lub iav kub kub puas tawg thiab tawg, thiab yog tias muaj, nws yuav tsum tau hloov raws sijhawm.Yog tias tsis yog, koj yuav tsum siv cov ntaub paj rwb mos dipped hauv dej lossis cawv los so cov pa phem ntawm nws qhov chaw.Thaum muaj cov tawv nqaij tawv tawv ntawm nws qhov chaw, koj tuaj yeem siv cov tshuaj ntxuav tshwj xeeb los ntxuav nws qhov chaw.
Nyob rau hauv lub preheat module, lub thermocouple yog siv los ntsuas qhov preheat kub thiab muaj lub luag haujlwm tseem ceeb heev.Feem ntau, cov thermocouple yog ntsia rau tib lub sijhawm nrog cov cua sov raj.Nyob rau hauv tus txheej txheem ntawm kev siv, yog hais tias lub thermocouple thiab lub cua sov raj tsis yog tib yam, xyuas seb nws puas puas, thiab hloov lub thermocouple nyob rau hauv lub sij hawm thaum xav tau.
3. Kev tu ntawm vuam module
Vuam module yog qhov tseeb tshaj plaws thiab tseem ceeb module ntawm kev xaiv vuam tshuab, nws yog feem ntau nyob rau hauv sab sauv ntawm cov cua kub cua sov module, nruab nrab ntawm lub thauj module thiab nyob rau hauv qis ib feem ntawm lub vuam module, nws cov kev ua hauj lwm ncaj qha cuam tshuam. qhov zoo ntawm Circuit Court board vuam, yog li nws cov kev saib xyuas kuj tseem ceeb heev.
Thaum lub nthwv dej pib khiav, yog tias lub nozzle tsis ua tiav los ntawm lub tshuab solder, qhov uas tsis ntub dej yuav thaiv cov ndlwg ntawm solder, thiab kev ruaj ntseg ntawm nthwv dej thiab qhov tseeb ntawm vuam yuav cuam tshuam zoo heev.Lub sijhawm no, lub nozzle yuav tsum tau ua haujlwm sai sai de-oxidation, txwv tsis pub lub nozzle yuav nrawm nrawm thiab tawg.
Wave soldering txheej txheem yuav tsim ib tug npaum li cas ntawm oxide (tsuas yog tin tshauv thiab dross), thaum nws yog ntau dhau yuav cuam tshuam rau lub tin mus, nws yog lub ntsiab ua rau khoob solder thiab bridging, tab sis kuj thaiv qhov chaw nres nkoj nitrogen, txo lub luag hauj lwm. ntawm nitrogen tiv thaiv, kom ceev oxidation ntawm solder.Yog li ntawd, nyob rau hauv cov txheej txheem vuam yuav tsum tau them sai sai rau kev tshem tawm cov tin tshauv dross, tab sis kuj xyuas seb lub qhov hluav taws xob nitrogen yog thaiv.
