Cov lus qhia tshwj xeeb rau kev siv hluav taws xob soldering hlau - siv thiab kev saib xyuas ntawm cov hlau taub hau
Kev kho ntawm soldering hlau taub:
1. Muab daim txhuam cev ntub dej ua ntej vuam, thiab tom qab ntawd nyem tawm cov dej ntau dhau. Tsuas yog nyob rau hauv txoj kev no tuaj yeem lub taub hau ntawm cov hlau soldering tau txais cov txiaj ntsig zoo tshaj plaws. Yog tias koj siv daim txhuam cev tsis ntub dej, nws yuav ua rau lub taub hau ntawm cov hlau soldering puas thiab ua rau nws tsis tin.
2. Thaum ua haujlwm soldering, cov txheej txheem soldering hauv qab no tuaj yeem tiv thaiv cov hlau txuas nrog cov hlua thiab txo cov oxidation.
3. Tom qab soldering, kho qhov kub txog li 250 degree, tom qab ntawd ntxuav lub taub hau ntawm cov hlau soldering, thiab ntxiv ib txheej tshiab ntawm tin rau kev tiv thaiv. (Yog tias koj siv cov hlau tsis muaj qhov kub thiab txias, txiav tawm lub hwj chim ua ntej, thiab cia qhov kub ntawm cov hlau taub hau poob me ntsis ua ntej tinning.)
4. Ceev faj
a. Sim siv qhov kub thiab txias ntawm qhov kub thiab txias yuav ua kom cov oxidation ntawm cov hlau taub hau thiab txo lub neej ntawm cov hlau taub hau. Yog hais tias qhov kub ntawm cov hlau taub hau tshaj 470 degree, nws yuav oxidize ob zaug sai li 380 degree.
b. Tsis txhob siv lub zog ntau dhau Thaum soldering, tsis txhob siv ntau lub zog, txwv tsis pub lub hau ntawm cov hlau yuav puas thiab deformed. Ntev npaum li lub taub hau hlau tuaj yeem tiv tauj rau qhov sib koom ua ke, cov cua sov tuaj yeem hloov mus. Tsis tas li ntawd, xaiv txoj cai soldering hlau taub kuj tuaj yeem pab hloov cov cua sov.
c. Nco ntsoov khaws cov tin rau ntawm qhov kawg ntawm cov hlau soldering, uas tuaj yeem txo txoj hauv kev ntawm oxidation ntawm lub taub thiab ua rau lub taub hau ntev dua. Tom qab siv, cov khoom siv tshiab yuav tsum tau muab ntxiv tom qab qhov kub ntawm cov hlau taub hau tau poob me ntsis, kom cov tin plating txheej muaj cov nyhuv zoo dua los tiv thaiv oxidation.
d. Khaws lub taub hau hlau kom huv si thiab tshem tawm cov oxides tam sim ntawd. Yog tias muaj cov oxide dub rau ntawm lub taub hau hlau, lub taub hau ntawm cov hlau tsis tuaj yeem raug tinned, thiab nws yuav tsum tau ntxuav tam sim ntawd. Thaum ntxuav, ua ntej kho qhov kub ntawm lub taub hau ntawm lub taub hau kom txog 250 degree, tom qab ntawd ntxuav cov hlau taub hau nrog ib daim txhuam cev ntxuav, thiab tom qab ntawd tin nws. Rov ua qhov kev txiav txim kom txog thaum cov oxide raug ntxuav.
e. Xaiv qhov ua haujlwm qis qis. High-activity los yog corrosive heev flux yuav ua rau kom lub corrosion ntawm lub soldering hlau taub thaum rhuab, yog li ntawd tsawg-corrosion flux yuav tsum tau xaiv. CEEB TOOM: Tsis txhob siv cov ntawv xuab zeb los yog cov khoom tawv los ntxuav lub taub hau hlau.
f. Muab cov hlau nplaum tso rau ntawm cov hlau nplaum thaum tsis siv cov hlau, cov hlau nplaum yuav tsum tau ua tib zoo muab tso rau ntawm cov hlau uas tsim nyog kom tsis txhob muaj kev puas tsuaj rau cov hlau taub vim kev sib tsoo.
g. Xaiv txoj cai soldering hlau taub Nws yog ib qho tseem ceeb heev uas yuav tau xaiv qhov loj thiab zoo ntawm cov hlau taub hau. Xaiv txoj cai soldering hlau taub yuav ua rau kev ua hauj lwm zoo dua thiab ua rau kom cov kav ntev ntawm cov hlau taub hau. Xaiv qhov tsis ncaj ncees lawm soldering hlau taub yuav cuam tshuam rau lub soldering hlau tsis muaj peev xwm ua tau ntawm nws lub ncov efficiency, thiab cov soldering zoo kuj yuav raug txo raws li qhov tshwm sim. Qhov loj ntawm lub taub hau ntawm lub taub hau yog ncaj qha ntsig txog lub peev xwm kub. Qhov loj dua qhov loj ntawm lub taub hau, qhov loj dua lub peev xwm kub, thiab qhov me me ntawm cov hlau taub hau, qhov me me lub peev xwm kub. Thaum ua haujlwm txuas ntxiv, siv lub taub loj dua kom txo qhov kub thiab txias. Tsis tas li ntawd, vim hais tias lub peev xwm ntawm lub taub hau loj loj yog qhov siab, qhov kub tsis tshua muaj peev xwm siv tau thaum lub sij hawm soldering, thiab lub taub hau hlau tsis yooj yim rau oxidize, uas ua rau nws lub neej nce. Qhov luv thiab tuab cov hlau taub hau ua kom sov sai dua thiab cov thinner soldering hlau taub yog sai dua thiab ruaj khov. Ib lub tiaj, blunt taub yuav hloov cua sov ntau tshaj qhov ntse ntse.
