Vim li cas thiab kev daws rau cov oxidation ntawm soldering hlau taub thiab nws tsis ua tiav kom nqus tin
Thaum siv cov hluav taws xob soldering hlau rau soldering ua haujlwm, nws yog ib txwm muaj los ntsib cov teeb meem ntawm solding hlau taub okidizing thiab tsis tau noj tin. Muaj ntau qhov laj thawj rau kev siv hlau cam tsis ua noj, tab sis ntev li peb nkag siab thiab cov laj thawj ntawm cov tshuab hlau tsis ua kom huv yuav tseem pom. Tsis tas li ntawd, peb kuj yuav tsum tau Master cov hau kev rau kev tuav cov lus qhia hlau hlau uas tsis noj cov ntaub ntawv.
Qhov teeb meem ntawm hluav taws xob soldering hlau taub oxidation tsis tau noj tin
1. Vim li cas rau tsis tau noj tin vim oxidation ntawm soldering Hlau Hlau
Nyob rau hauv cov txheej txheem ntawm kev siv cov hluav taws xob soldering hlau, qhov teeb meem tshaj plaws yog qhov hlawv ntawm soldering cam taub. Yuav ua li cas nrog cov xwm txheej no? Hauv qab no yog qee txoj hauv kev sau cov ntsiab lus tau tshaj xyoo.
Txhawm rau tiv thaiv cov hlau cam los ntawm hlawv kom tuag thiab tsis tau noj tin, nws yog qhov tsim nyog kom xub nkag siab vim li cas cov hlau tsis noj. Qhov laj thawj tseem ceeb vim li cas thiaj li cov tub taub hlau tsis tau noj tsis tau noj yog vim tias cov cam taub cuam tshuam rau lub sijhawm ntev. Qhov no yog qhov yuam kev tshaj plaws ua los ntawm cov phooj ywg uas yog cov tshiab rau hluav taws xob hluav taws xob. Lawv feem ntau tsis nco qab mus rho lub hwj chim thaum cuam tshuam nrog lwm yam, ua rau cov cam taub hlau tawg mus hlawv tawm hauv huab cua. Thaum lub sijhawm cua hlawv, qhov kub ntawm solding hlau ntxeev siab yog heev heev, kwv yees li 380 degrees Celsius.
Muaj ob qho xwm txheej, nyob ntawm seb puas shoding hlau taub yog ua los ntawm tooj liab hlau lossis hlau hlau, qhov tshwm sim sib txawv yog qhov sib txawv.
(1) Soldering Hlau Taub yog ua los ntawm tooj liab hlau
Nws yuav tshwm sim nrog cov pa hauv huab cua thiab tsim cov tooj liab oxide rau saum npoo. Yog tias cov hlua khi tau melted, yuav muaj cov kua kheej kheej ntawm tin rau saum npoo ntawm cov hlau qub taub hau. Yog tias oxidation yog loj, nws yuav tsis lo rau tin txhua. Qhov no yog qhov thiaj li hu ua "taub hau taub hau tsis noj cov tin".
(2) Qhov ntxeev ntawm cov hluav taws xob soldering hlau yog ua los ntawm cov hlau hlau
Vim tias lub sijhawm ntev raug rau cov cua sov, nws yuav hloov mus rau hauv cov hlau hlau dub oxide, uas tseem nyuaj rau haus.
2. Cov qauv ntawm kev kho cov lus ntuas cov hlau uas tsis muaj kev siv tin
Cov lus qhia zoo ib txwm siv soldering hlau cov lus qhia suav nrog cov tswv yim tooj liab thiab alloy, tooj, npib tsib xee, thiab tin.
