Soldering hlau - lwm yam kev yuav khoom
1. Kub qhov tseeb ntawm vuam taub
tus
Niaj hnub no, cov khoom siv hluav taws xob yuav tsum tau ua kom me me thiab meej dua, thiab qhov kev xav tau ntawm qhov kub thiab txias tau nruj dua, yog li qhov ntsuas kub ntawm cov hlau soldering kuj tseem ceeb heev. Ntau tus neeg xav tias yog tias muaj qhov sib txawv ntawm qhov ntsuas kub thiab qhov ntsuas kub ntawm lub taub hau, nws txhais tau hais tias kev ua haujlwm ntawm cov hlau soldering yog faulty los yog puas, tab sis qhov no tsis yog li ntawd. Qhov sib txawv ntawm qhov ntsuas kub thiab qhov kub ntawm qhov tseeb yog feem ntau cuam tshuam los ntawm ob yam, suav nrog qhov loj thiab cov duab ntawm lub solder tsis kam, qhov poob ntawm lub taub thiab cov cua sov core. Yog xav paub meej, thov mus saib "Title 7 Qhov kev sib raug zoo ntawm qhov kub thiab txias ntawm qhov chaw nres tsheb vuam thiab qhov tseeb qhov kub ntawm qhov vuam taub" hauv phau ntawv no.
2. Kev tswj qhov kub thiab txias
Thaum siv cov ntsuas kub tswj cov hlau, qee tus neeg ua haujlwm tuaj yeem hloov qhov kub ntawm lub siab los yog tsis txhob txwm, thiab tsis rov qab qhov kub ntawm qhov qub tom qab qhov kev hloov pauv, uas yuav cuam tshuam rau kev ua haujlwm vuam. Txhawm rau kom tsis txhob muaj qhov xwm txheej zoo li no, qhov ntsuas kub-kho cov hlau yuav tsum tau nruab nrog qhov ntsuas kub hloov ntsuas ntsuas kom ntsuas qhov ntsuas kub. Qee cov hlau nplaum muaj qhov ntsuas kub hloov pauv, xws li WD1000, thiab lwm yam.
3. Kev nyab xeeb ntawm cov khoom siv hluav taws xob
Thaum soldering, cov hlau soldering yog nyob rau hauv kev sib cuag ncaj qha nrog cov khoom siv hluav taws xob. Yog tias cov hlau nplaum nws tus kheej muaj hluav taws xob zoo li qub lossis qhov hluav taws xob loj heev, nws yuav ua rau qee cov khoom siv hluav taws xob puas ntsoog rau hluav taws xob zoo li qub lossis hluav taws xob to. Yog li ntawd, thaum soldering ib co rhiab Cheebtsam, nws yog tsim nyog los xaiv ib tug hluav taws xob soldering hlau nrog anti-static muaj nuj nqi (ESD). Tsis tas li ntawd, xaiv ib tug soldering hlau uas tsis tshua muaj to voltage. Piv txwv li, vuam chaw nres tsheb xws li WSD81 yog tsim los tiv thaiv zoo li qub, thiab siv 24 volts los ua kom sov; Cov khoom siv cua sov uas tsis tshua muaj hluav taws xob thiab kev tiv thaiv hluav taws xob siab tuaj yeem ua rau qhov chaw nres tsheb vuam muaj qhov xau hluav taws xob qis dua 2 millivolts; siv cov ntaub ntawv tiv thaiv zoo li qub nrog tus nqi ntawm qhov impedance ntawm 105 ~ Thaum nws nyob nruab nrab ntawm 109Ω, nws muaj kev nyab xeeb thiab txhim khu kev qha txawm tias cov khoom rhiab heev yog welded.
4. Kev nyab xeeb rau cov neeg siv
Thaum xaiv cov hlau soldering, koj yuav tsum tau saib xyuas tus neeg siv khoom siv. Yog tias soldering tau ua tiav ntawm cov kab ntau lawm, tus neeg teb xov tooj yuav tsum tau tuav cov hlau ntev ntev los ua cov haujlwm soldering. Nyob rau hauv txoj kev no, kev tsim cov duab ntawm cov hlau soldering nws tus kheej yog qhov tseem ceeb heev. Yog tias cov hlau nplaum nws tus kheej loj dhau los yog hnyav dhau, tus neeg teb xov tooj yuav nkees lossis tsis xis nyob, thiab kev ua haujlwm yuav raug txo. Cov hlau soldering nrog lub teeb tshwj xeeb, xis thiab yooj yim-rau-tswj kov tuaj yeem siv tau ntev yam tsis muaj kev nkees, yog li txhim kho kev ua haujlwm. Tsis tas li ntawd, kev siv lub tshuab hluav taws xob qis hluav taws xob tuaj yeem tiv thaiv hluav taws xob vim qhov xau.
