Plaub yog vim li cas rau oxidation sai ntawm cov lus qhia hlau soldering
1. Qhov teeb meem zoo ntawm lub taub hau soldering: Tsis zoo ntawm lub taub hau soldering tuaj yeem cuam tshuam rau kev siv tau zoo.
2. Yog tias qhov kub thiab txias heev, nws yuav ua kom sov sai sai thiab yooj yim hlawv cov hlau taub hau. Qhov kub thiab txias yog ze ze rau cov hlau soldering siv. Piv txwv li, siv cov hlau tsis tu ncua yuav tsum muaj qhov kub ntawm 350 degrees, tab sis vim lub zog tsis txaus thaum siv, nws yuav tsum tau hloov mus rau 380 degrees ua ntej yuav siv tau.
3. Qhov teeb meem txij nkawm tsis txaus: Tin yuav tsum tau siv txhua zaus nws siv los tiv thaiv oxidation.
4. Lub taub hau ntawm lub taub hau yog deformation lossis perforation.
Txoj kev kho kom ceev oxidation ntawm soldering hlau taub hau
Nws yog txwv tsis pub "scrape" lub taub hau hlau nrog cov cuab yeej ntse lossis cov ntawv xuab zeb los tiv thaiv kev puas tsuaj rau lub neej kev pab cuam ntawm lub taub hau hlau.
1. Tsis zoo soldering hlau muaj qhov kub thiab txias, thaum zoo soldering hlau muaj cua sov qeeb thiab tsis kub, ua rau nws nyuaj rau hlawv lub taub hau soldering hlau. Txhawm rau kom ntseeg tau tias kev siv ib txwm siv ntawm lub taub hau hlau soldering, nws yog ib qho tsim nyog los xyuas kom meej qhov zoo thaum xaiv.
2. Qhov kub thiab txias yuav ua kom cov oxidation ntawm lub taub hau hlau soldering thiab txo nws txoj sia. Qhov siab dua qhov kub, qhov kev pab cuam lub neej ntawm lub taub hau hlau soldering luv dua. Rau txhua txhua 20 degree nce, lub neej kev pab cuam ntawm lub taub hau soldering hlau yog txo los ntawm ib nrab. Yog li ntawd, nyob rau hauv lub hauv paus ntawm ua tau raws li lub welding tej yam kev mob, low-temperature welding yuav tsum tau siv ntau li ntau tau.
3. Muab lub taub hau taub hau rau hauv rosin thiab siv cov tin soldering. Yob nws rau hauv thiab cov oxide yuav poob sai sai. Tom qab siv nws tsis tu ncua, sau lub taub hau nrog tin kom txog thaum nws tsis tuaj yeem lo. Lwm zaus, so nws nrog daim txhuam cev ntub dej thiab nws yuav ci heev.
4. Hloov lub taub hau hlau.
Cov kev ceev faj:
Nws yog txwv tsis pub siv cov ntaub ntawv tshem tawm oxides los ntawm qhov vuam taub.
Cov hluav taws xob soldering hlau taub hau hlawv kom tuag, nthuav tawm ib txheej tsaus nti lossis tsis muaj tin melting. Koj tuaj yeem siv cov hniav los txhuam lub taub hau kom huv, nthuav tawm qhov tooj liab. Lub scraping ceev ceev, tsis txhob siv ntau dhau, thiab tam sim ntawd yaj cov hlau soldering rau saum tom qab scraping.
Qhov tsis zoo ntawm txoj kev no yog tias kev ua haujlwm mus sij hawm ntev yuav ua rau lub neej luv ntawm lub taub hau soldering hlau.
Nco ntsoov tias thaum tsis siv qhov chaw nres tsheb soldering, tsis txhob tso cov hlau nplaum rau hauv lub xeev kub ntev ntev. Qhov no tuaj yeem ua rau cov flux ntawm lub taub hau hlau hloov mus rau hauv oxides, uas tuaj yeem ua rau oxidation ntawm cov plaub hau hlau thiab txo cov thermal conductivity ntawm cov hlau taub hau.
Thaum lub rooj vuam tsis siv, nws yog ib qho tsim nyog yuav tsum tau tua hluav taws xob, feem ntau yog rau cov rooj vuam uas tsis muaj qhov kub thiab txias los yog tsis muaj qhov tsis siv neeg pw tsaug zog.
