Cov teeb meem dab tsi yuav tsum tau them nyiaj rau hauv phau ntawv soldering ntawm 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. Yog li, dab tsi teeb meem yuav tsum tau them sai sai rau hauv phau ntawv soldering ntawm PCB aluminium substrate?

1. Ua tib zoo saib xyuas qhov kub thiab txias

Vim yog qhov tshwj xeeb ntawm cov khoom siv aluminium substrate, txhawm rau kom ntseeg tau tias cov nyhuv vuam, nws yog ib qho tsim nyog los xyuas kom meej qhov kev ua haujlwm ntawm qhov kub thiab txias thaum lub sij hawm vuam, qhov vuam kub yuav tsum tau khaws cia kom zoo li qub, thiab qhov tseeb vuam yuav tsum tau them. saib rau. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua tiav daim ntawv thov zoo heev.

2. Xaiv cov khoom siv raw

Hauv cov txheej txheem vuam, kev xaiv cov ntaub ntawv tsim nyog yog qhov tseem ceeb tshwj xeeb. Sim xaiv ib co ultra-low kub electrodes thiab lawv cov txheeb ze flux, kom cov vuam nyhuv yuav zoo dua.

3. Nws yog teeb meem rau kev siv dag zog rau qhov chaw vuam nrog lub taub hau hlau

Lub hau ntawm cov hlau soldering xa cov cua sov mus rau qhov chaw vuam. Qhov tseem ceeb yog ua kom tag nrho cheeb tsam sib cuag. Siv hluav taws xob soldering hlau los ntxiv dag zog rau qhov chaw vuam tsis muaj kev cuam tshuam rau cov cua sov, thiab ntau zaus, nws tuaj yeem ua rau qhov chaw welded puas. Soldering cov ntsiab lus xws li resistors, fais fab hloov, thiab connectors feem ntau tsau rau ntawm cov yas prefabricated Cheebtsam.

Cov ntsiab lus: Txawm hais tias phau ntawv vuam tsis tshua muaj siv nyob rau hauv kev tsim thiab tsim cov khoom siv hluav taws xob loj, phau ntawv vuam tseem yog qhov tseem ceeb rau kev saib xyuas thiab kho cov khoom siv hluav taws xob. Nyob rau tib lub sijhawm, kev tuav vuam yog ib qho kev ua haujlwm theoretical, thiab qhov zoo ntawm vuam yuav ua rau cov nyhuv tu.

Cov saum toj no yog qee qhov teeb meem uas yuav tsum tau them sai sai rau hauv phau ntawv soldering ntawm PCB aluminium substrates.
