Thaum sourcing Tin hlau rau soldering daim ntawv thov, cov tub yuav khoom yuav tsum xav txog ntau yam kom ntseeg tau tias lawv xaiv cov khoom lag luam zoo tshaj plaws. Tin hlau yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob, cov kav dej, thiab ntau lwm yam kev lag luam, thiab kev ua tau zoo rau kev ncaj ncees thiab kev ntseeg tau ntawm cov khoom kawg.
Ib qho kev txiav txim siab thawj zaug thaum kev yuav cov Tin hlau yog nws cov lus sib xyaw. Tin hlau feem ntau muaj nyob rau hauv ntau lub alloys, feem ntau ua ke nrog lwm cov hlau xws li coj, nyiaj, lossis tooj liab los txhim kho cov khoom tshwj xeeb. Piv txwv li, cov hlau txhuas yog dav siv hauv cov khoom hluav taws xob vim nws cov cwj pwm zoo tshaj plaws thiab qis melting point. Txawm li cas los xij, vim kev tswj hwm ib puag ncig thiab kev noj qab haus huv, lwm txoj hauv kev dawb, xws li alloys nyiaj, tin-tooj liab. Cov kev xaiv pub dawb no tsis tsuas yog ua raws cov qauv kev cai tab sis kuj muab kev ua tau zoo thiab ntseeg tau
Lub cheeb ntawm tin hlau yog lwm qhov tseem ceeb. Cov hlau tuab tuaj yeem cuam tshuam cov txheej txheem soldering thiab qhov zoo ntawm cov pob qij txha sib dhos. Cov hlau nplua-lub ntsuas hluav taws xob yog tsim nyog rau cov khoom siv hluav taws xob siv hluav taws xob, muab cov qauv ntsuas hluav taws xob, thaum tuab dua rau cov pob qij txha loj thiab cov ntawv thov xav tau ntau dua. Txhim kho qhov uas haum kom haum rau koj cov kev xav tau tshwj xeeb yog qhov tseem ceeb tshaj plaws rau kev ua tiav qhov kev pom zoo hauv koj cov phiaj xwm solding.
Purity yog qhov tseem ceeb tseem ceeb rau Tin Hlau. High-purity tin hlau ua kom muaj kev ua tau zoo sib xws, nrog kev ua kom tsawg kawg uas tuaj yeem ua rau cov txheej txheem soldering. Impurities nyob rau hauv lub tin hlau tuaj yeem ua rau kev ntub dej tsis zoo, pob qij txha tsis muaj zog, thiab cov peev xwm ua tsis tiav hauv cov khoom kawg. Yog li ntawd, sourcing Tin hlau los ntawm cov npe nrov uas lav tau cov qauv kev ua raws siab yog qhov tseem ceeb.
Lub flux tseem ceeb ntawm lub tin hlau tseem ua lub luag haujlwm tseem ceeb hauv nws qhov kev ua tau zoo. Cov flux pab ntxuav thiab npaj cov chaw kom sib dhos, ua kom muaj zog thiab txhim khu kev qha pob qij txha. Txawv sib txawv ntawm cov corines flux, xws li Rosin, cov dej-soluble, thiab tsis muaj-huv si flux, muaj, txhua qhov uas haum rau cov ntawv thov thiab kev tu kom huv. Xaiv cov hom txoj cai flux raws koj cov txheej txheem ntau lawm thiab ua kom cov khoom siv tu kom huv yog qhov tseem ceeb.
Ntim thiab ntim khoom rau cov hlau hlau yuav tsum tsis txhob saib dhau. Ntim kom tiv thaiv cov hlau los ntawm kev sib kis thiab oxidation, tswj nws qhov zoo kom txog thaum nws siv. Tus neeg muab khoom uas muaj kev ruaj ntseg thiab cov ntaub ntim yooj yim ntim ua kom muaj kev sib txuas lus tag nrho thiab kev cia siab, kom ua rau lub tin hlau tseem nyob rau hauv qhov kev mob zoo.
Thaum kawg, ntsuas cov khoom xa tuaj kev cia siab thiab txhawb nqa yog qhov tseem ceeb. Ib tus neeg xa khoom ntseeg nrog cov ntaub ntawv sau tseg ntawm kev muab cov hlau lag luam zoo tuaj yeem muab cov khoom muaj txiaj ntsig zoo, uas yog cov caij nyoog ua kom muaj txiaj ntsig zoo.
Hauv kev xaus, thaum kev yuav cov hlau hlau rau soldering cov ntawv thov, xav txog xws li muaj pes tsawg leeg, lub taub, ntim, thiab xa khoom noj kom zoo. Los ntawm kev xav txog cov kev txiav txim siab tseem ceeb no, cov neeg yuav khoom yuav ruaj ntseg zoo li lawv cov kev xav tau thiab txhawb nqa kev txhim khu kev qha, cov khoom lag luam zoo.
