Dab tsi yog cov teeb meem ntawm phau ntawv soldering hlau rau PCB aluminium substrate

Hauv kev tsim cov txheej txheem ntawm PCB aluminium substrate, txhawm rau txhawm rau ua kom nws cov txiaj ntsig zoo dua, phau ntawv soldering ntawm tin hlau feem ntau yog siv tom qab. Qhov no muaj qee qhov yuav tsum tau ua rau vuam. Yog tias qhov vuam tsis ua tiav zoo, yuav muaj kev puas tsuaj loj. Tsuas yog los ntawm kev daws txhua yam teeb meem thaum lub sij hawm soldering tuaj yeem ua kom ntseeg tau tias PCB aluminium substrate yuav kav ntev dua.

Yog li, dab tsi yog qhov teeb meem ntawm PCB aluminium substrate phau ntawv soldering hlau? Hauv qab no yog cov lus teb rau txhua tus.

Ib qho: Ua tib zoo saib xyuas qhov kub thiab txias

Vim qhov tshwj xeeb ntawm cov khoom siv PCB aluminium substrate, txhawm rau ua kom cov txiaj ntsig ntawm nws cov vuam, nws yog ib qho tsim nyog los xyuas kom meej qhov kev ua haujlwm ntawm qhov kub thiab txias thaum lub sijhawm vuam, thiab tib lub sijhawm, nws tuaj yeem tsim nyog zam qhov tshwm sim ntawm qee qhov kev ua haujlwm. teeb meem. Lub vuam kub yuav tsum tau khaws cia kom tsis tu ncua li sai tau, thiab yuav tsum tau them nyiaj mloog mus rau qhov tseeb vuam. Tsuas yog nyob rau hauv txoj kev no yuav ua tau zoo heev daim ntawv thov cov nyhuv yuav guaranteed tiag.

Ob: xaiv cov khoom siv raw

Hauv cov txheej txheem vuam, kev xaiv cov ntaub ntawv tsim nyog yog qhov tseem ceeb tshwj xeeb. Nyob rau hauv cov ntaub ntawv ntawm vuam, sim xaiv ib co ultra-tsawg kub electrodes thiab lawv cov txheeb ze flux, thiaj li hais tias cov vuam nyhuv yuav zoo dua. Nws raug nquahu kom tsis txhob siv cov flux cored fluxes, vim tias tom qab ntawd yuav muaj teeb meem loj, thiab cov vuam txuas ntxiv yuav raug mob rau qee yam.

Xaiv cov khoom tsim nyog rau vuam, cov nyhuv yuav zoo dua.

Peb: Nws yog ib qho teeb meem rau kev siv quab yuam kom pom qhov vuam nrog lub taub hau hlau

Lub taub hau hlau soldering xa cov cua sov mus rau qhov chaw vuam. Qhov tseem ceeb yog ua kom tag nrho cheeb tsam sib cuag. Kev siv hluav taws xob soldering hlau los ntxiv dag zog rau qhov chaw vuam tsis muaj qhov cuam tshuam rau cov cua sov. Feem ntau, nws tuaj yeem ua rau puas tsuaj rau qhov chaw welded. Soldering cov ntsiab lus xws li resistors, fais fab hloov, thiab connectors feem ntau tsau rau cov yas prefabricated Cheebtsam. Qhov no yuav tsum tau ua kom ntseeg tau qhov tseeb ntawm cov vuam hlau.

Tom qab tag nrho, phau ntawv welding yog ib txwm siv txoj kev vuam. Txawm hais tias phau ntawv welding tsis tshua muaj siv nyob rau hauv kev tsim thiab tsim khoom ntawm cov khoom siv hluav taws xob loj, phau ntawv vuam yog inevitably siv hauv kev saib xyuas thiab kho cov khoom siv hluav taws xob. Nyob rau tib lub sij hawm, qhov zoo ntawm vuam yuav ua rau cov nyhuv txij nkawm. Raws li kev txawj tshaj lij nrog cov kev xav tau muaj zog, kev tuav vuam yuav tsum muaj kev xyaum ntau dua thiab kev xyaum ua kom ntseeg tau zoo heev vuam zoo!
