Thaum kho cov khoom siv hluav taws xob hauv tsev, qhov loj npaum li cas hluav taws xob soldering hlau feem ntau siv?
Taw qhia ntawm hluav taws xob soldering hlau
Lub tshuab hluav taws xob hluav taws xob feem ntau yog tsim los ntawm lub taub hau taub hau, lub taub hau cua sov, lub kov, lub hwj chim qaum, thiab lub tshuab hluav taws xob (lub chaw nres tsheb muaj lub tshuab hluav taws xob). Raws li cov qauv siv tshuab, hluav taws xob soldering hlau tuaj yeem muab faib ua ob hom: hom cua sov sab hauv thiab sab nraud cua sov hom. Yog tias koj xav hais tias qhov twg yog qhov zoo dua, Nws tsuas tuaj yeem hais tias ob leeg muaj qhov zoo thiab qhov tsis zoo, thiab txhua tus muaj nws tus kheej siv.
Vim li cas thiaj hu ua cua sov sab hauv
Lub taub hau ntawm cov cua sov sab hauv hom hluav taws xob soldering hlau yog hollow, uas yuav tsum tau paub rau cov neeg uas tau siv nws. Vim hais tias cov cua sov sab hauv hom soldering hlau yog tshwj xeeb hauv cov qauv, nws cov tub ntxhais cua sov yog ncaj qha mus rau sab hauv ntawm lub hollow soldering hlau taub, yog li lub npe muab rau nws kuj hu ua cov cua sov sab hauv hom hluav taws xob soldering hlau. Lub zog ntawm cov cua sov hauv hluav taws xob soldering hlau feem ntau me me, feem ntau qis dua 60W.
Vim li cas thiaj hu ua cua sov sab nraud
Lub taub hau ntawm sab nraud cua sov hluav taws xob soldering hlau yog cov khoom, thiab nws cov tub ntxhais cua sov ncaj qha qhwv cov khoom siv hlau, yog li nws yog hu ua hluav taws xob hluav taws xob sab nraud. Lub zog ntawm sab nraud cua sov hluav taws xob soldering hlau feem ntau kuj loj, thiab lub ntim kuj tseem loj, thiab ntau ntawm lawv tuaj yeem ncav cuag ntau dua 60W.
Classification ntawm soldering hlau taub
Cov tswv yim hlau soldering tuaj yeem muab faib ua: lub taub hau taw, lub taub hau luv luv, nkhaus taw taub hau, lub taub hau riam, lub taub hau me me, lub taub hau nyias nyias, lub taub hau nees, lub taub hau tiaj tus, lub taub hau ntev, lub taub hau luv luv, thiab lub taub hau puag ncig.
Sab nraud tshav kub soldering hlau
Vim tias nws cov ntsiab lus hlau yog yooj yim heev rau oxidize, oxidized soldering hlau taub yog qhov tseem ceeb. Tsis tas li ntawd, nws yog qhov loj, thiab qee qhov kev sib txuas tsis yooj yim heev, yog li cov cua sov sab nraud hluav taws xob soldering hlau tsis pom zoo nyob ntawm no, thiab cov cua sov sab hauv hluav taws xob soldering hlau tau pom zoo ncaj qha.
Yog li ntawd, nws raug nquahu kom siv cov cua sov sab hauv hom hluav taws xob soldering hlau. Ntawm no kuv xav kom ib tug kuj zoo thiab yooj yim-rau-siv sab hauv cua sov hom hluav taws xob soldering hlau, uas yog Gaojie Huanghua lub 907 hluav taws xob soldering hlau (tsuas yog nrhiav Huanghua 907). Cov phooj ywg uas tau siv nws yuav tsum paub tias lub tshuab hluav taws xob hluav taws xob no Lub tshuab hluav taws xob yog qhov ruaj khov, thiab qhov kub thiab txias tuaj yeem hloov kho, thiab cua kub ceev ceev heev.
1. Tshem tawm cov hluav taws xob soldering hlau hauv lub sijhawm tom qab siv
Ntau tus neeg tawm ntawm cov hlau soldering nyob rau hauv lub tshav kub tom qab siv nws. Nyob rau lub sijhawm no, qhov ntxeev ntawm cov hlau soldering yog nyob rau hauv lub xeev ntawm kub kub, thiab nws yog ib qho yooj yim mus oxidized. Thaum lub taub hau ntawm cov hlau soldering yog oxidized, nws yuav nyuaj rau siv lwm zaus. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau tshem tawm cov hluav taws xob soldering hlau ntsaws rau hauv lub sijhawm thaum siv.
2. Tin plating ntawm qhov kawg ntawm cov hlau soldering
Kuv tsis paub yog tias koj muaj tus cwj pwm ntawm tinning, tab sis tus sau ib txwm tuav tus cwj pwm ntawm tinning. Vim tias tom qab siv cov hlau soldering, yog tias cov hlau nplaum tsis yog tinned, cov hlau nplaum yuav raug oxidized vim qhov kub thiab txias, thiab qee qhov yuav tig dub ncaj qha, uas yuav cuam tshuam rau kev siv cov hlau soldering lwm zaus.
3. Tsis txhob siv cov kua qaub kua qaub
Txhawm rau ua kom vuam yooj yim dua, qee cov neeg siv yuav siv qee qhov flux. Feem ntau ntawm cov fluxes no yog acidic, thiab corrosion ntawm cov hlau taub hau yog qhov hnyav heev nyob rau hauv qhov kub thiab txias.
Qhov zoo tshaj plaws flux yog rosin, thiab flux ntawm rosin yuav tsum tau siv tag nrho. Rosin tuaj yeem ua rau hauv hmoov thiab tov nrog cawv. Lawv tuaj yeem siv ua flux thiab cov nyhuv zoo heev. (25% rosin yaj hauv 75% cawv)
