Cov yam ntxwv thiab qhov sib txawv ntawm cov khoom siv tooj liab thiab tooj dag ntawm lub taub hau hlau soldering
Yog vim li cas vim li cas lub taub hau hlau siv cov khoom siv tooj liab liab yog ua raws li cov hauv qab no: Thawj qhov kev xaiv ntawm cov khoom siv rau lub taub hau hlau yog tias cov molecules ntawm cov khoom ntawm cov hlau taub hau yuav tsum muaj affinity nrog cov molecules ntawm lub solder, yog li ntawd lub taub hau hlau tuaj yeem dipped tom qab cua sov. Soldering yog yooj yim rau kev siv vuam; Thib ob, lub peev xwm tshwj xeeb ntawm cov khoom siv ntawm lub taub hau yog loj dua, uas yog hais tias, qhov kev ua haujlwm thermal rwb thaiv tsev zoo dua; oxidation kuj ntawm cov khoom yog zoo nyob rau hauv vuam kub. Ua ntej lub alloy ntev-lub neej soldering hlau taub tau tshwm sim, tooj liab, ib qho ntawm cov ntaub ntawv hlau uas tau ntsib cov xwm txheej saum toj no, yog thawj cov khoom siv.
Liab tooj liab yog tus cwj pwm los ntawm kev kub ceev ceev thiab yooj yim tinning, tab sis nws tsis yog resistant rau corrosion, thiab soldering hlau taub yog tsis muaj zog txaus rau micro-soldering, thiab lub soldering hlau taub yog yooj yim deformed thiab tawg. Tam sim no lub ntsis ntawm cov hlau soldering yog ua los ntawm cov hlau uas tsis yooj yim rau tawg, thiab cov txheej sab nrauv yog corrosion-resistant thiab yooj yim rau siv tin txheej. Txawm hais tias lub tshav kub conduction tsis zoo, nws muaj kev cuam tshuam me ntsis, tab sis nws muaj zog heev.
Qhov siab dua qhov purity ntawm tooj liab, qhov ntau ruaj nws yog, thiab qhov denser nws yog, qhov ntau ruaj nws yog. Yog vim li cas rau qhov ablation ntawm tooj liab soldering hlau taub yog qhov kub thiab txias heev. Cov tooj liab thiab cov hlau lead-tin alloy ua ke los ua cov hlau uas muaj tooj liab, uas yog melted thiab corroded. Tus tshiab tooj liab soldering hlau taub Tom qab cua sov mus rau 350 degrees thiab clamping, rauj thiab forge ib feem uas noj tin, uas yuav ua tau zoo heev rau lub neej kev pab cuam. solder nrog kub-kub solder (xws li txhuas) thiab nyiaj soldering hlau taub yuav siv tau.
tooj dag soldering hlau taub muaj cov cua kub tsis zoo, thiab nws muaj zog dua tooj liab thaum nws qis dua 400 degrees. Nws yog ablated sai dua thaum nws tshaj 450 degrees, thiab nws yog deb tshaj tooj liab. Nyob rau hauv qhov kev ntsuam xyuas zaum kawg, lub neej ntawm soldering hlau taub yog nyob ntawm ntau lub sij hawm ua hauj lwm kub ntawm lub soldering hlau taub.
Copper - Raws li cov khoom siv hluav taws xob, nws yog cov khoom tseem ceeb ntawm cov hlau taub hau (soldering hlau taub). Kev suav txog li ntawm 85 feem pua ntawm cov khoom siv ntawm lub taub hau hlau, tooj liab muaj cov thermal conductivity zoo, uas yog qhov zoo rau cov cua kub ceev ntawm cov hlau taub hau. Cov lus qhia zoo soldering hlau yog ua los ntawm tooj liab. Tam sim no, qee cov tuam ntxhab siv tooj dag lossis txawm tias hlau ncaj qha rau cov txiaj ntsig. Tus nqi yog txo, thiab cov nyhuv tshav kub ntawm lub taub hau soldering kuj txo.
Txawm hais tias hom soldering hlau taub koj siv, nws xav tau kev saib xyuas. Lub npe hu ua kev saib xyuas, ib qho yog tsis txhob siv nws ntawm qhov kub thiab txias, lwm qhov yog tsis txhob cia koj cov hlau taub hau kub hnyiab hauv huab cua yam tsis muaj kev tiv thaiv ntawm solder, thiab qhov thib peb yog siv daim txhuam cev kub los ntxiv dej. thaum ntxuav lub taub hau hlau, thiab tsis txhob khawb nws nrog ib qho khoom ntse.
