Kev xaiv hluav taws xob soldering hlau thiab txoj kev soldering
Thaum xaiv ib qho hluav taws xob soldering hlau, nws feem ntau txiav txim siab los ntawm qhov loj ntawm qhov taw tes soldering. Yog hais tias thaj tsam ntawm qhov taw tes soldering yog loj, lub tshav kub dissipation ceev kuj ceev. Yog li ntawd, hluav taws xob soldering hlau xaiv muaj cua sov ceev thiab muaj zog dua. Peb nquag siv cov hlau nplaum uas muaj zog ntawm 20W, 25W, 30W, 35W, 50W, thiab lwm yam. Xaiv lub zog ntawm ib ncig ntawm 30W yog qhov tsim nyog dua. Ntawm no, tus editor yog siv lub tshuab hluav taws xob sawv ntsug, uas yog hom uas muaj nyob hauv daim duab 1. Cov cua sov tuaj yeem hloov kho txhua lub sijhawm, uas yooj yim, tab sis nws tsis yooj yim rau nqa. Daim duab 2 yog ib qho yooj yim nqa, tab sis cov cua sov tsis ruaj khov.
Tom qab siv lub sijhawm ntev, lub taub hau hlau yuav tsim ib txheej ntawm oxide, uas tsis yooj yim rau solder. Peb tuaj yeem ua cov txheej txheem oxide los yog txhuam nws nrog rab riam me me. Tom qab ntawd, tig cov hlau nplaum, ua kom sov me ntsis, thiab koj tuaj yeem siv rosin. Tom ntej no, siv lub soldering tin.
Thaum xaiv cov solder, peb yuav tsum siv cov hlau nplaum uas tsis tshua muaj melting point thiab tsis corrosive flux, xws li rosin. Kev lag luam solder thiab corrosive acidic solder roj yuav tsum tsis txhob siv. Tau kawg, tseem muaj ib hom solder hlau nyob rau hauv kev ua lag luam uas muaj rosin, uas yooj yim heev rau peb siv.
Ceeb Toom: Cov hlau tshiab yuav tsum tau coated nrog rosin thaum siv thawj zaug.
Lub hom phiaj ntawm lub tin absorber yog tshem tawm cov hlau vuam ntau dhau thiab disassemble cov khoom siv hluav taws xob.
Lub hom phiaj ntawm kev ntxuav daim txhuam cev: Thaum siv, nws yuav tsum tau tsau rau hauv dej huv kom tshem tawm cov av ntawm qhov kawg ntawm cov hlau soldering, ua kom yooj yim rau tin. Tom qab siv cov hlau soldering, siv nws los ntxuav lub hau.
5. Vuam txoj kev
Cov lus qhia ua haujlwm: Thaum tshav kub kub ua ntej thiab tom qab ntawd solder, tshem tawm solder ua ntej thiab tom qab ntawd tshem cov hlau soldering.
Thaum lub sij hawm khaws cia ntawm cov khoom siv hluav taws xob, vim yog cov nyhuv oxidation ntawm huab cua, muaj ib txheej ntawm oxide zaj duab xis txuas rau cov pins ntawm cov khoom, nrog rau lwm cov av. Ua ntej soldering, peb yuav tsum tau ntxuav lub Cheebtsam thiab coated lawv nrog ib tug txheej ntawm tin. Ua li ntawd, cov pob qij txha uas peb welding ua ke tsis tshua muaj kev paub txog kev siv tshuab.
Vuam kub thiab vuam lub sij hawm
Peb yuav tsum xaiv qhov ntsuas kub kom haum thaum soldering, uas yuav tsum siab tshaj qhov ntsuas kub. Yog tias siab dhau, nws tsis zoo. Hauv cov xwm txheej hnyav, cov ntaub qhwv ntsej muag yuav poob ncaj qha. Nws yog qhov zoo dua los siv lub taub hau hlau uas nyuam qhuav haus luam yeeb thaum nws los rau hauv kev sib cuag nrog rosin.
Lub sij hawm vuam yog luv luv, qhov kub ntawm qhov sib koom ua ke yog tsawg heev, lub melting ntawm solder sib koom tsis txaus, thiab cov solder sib koom yog ntxhib, uas tuaj yeem yooj yim ua rau virtual soldering. Hloov pauv, yog tias lub sijhawm vuam ntev dhau lawm, cov khoom siv tau yooj yim ntws thiab cov khoom ua rau overheating thiab puas.
Tus naj npawb ntawm cov ntsiab lus ntawm qhov sib koom ua ke
Peb yuav tsum tswj tus nqi ntawm cov solder ntawm cov pob qij txha zoo. Tus nqi ntawm cov solder ntawm cov pob qij txha yuav tsis tuaj yeem tsawg dhau. Yog hais tias nws yog me me, lub soldering yuav tsis ruaj, thiab cov pob qij txha yuav tiaj tus, ua rau cov neeg kho tshuab tsis zoo. Yog tias muaj ntau dhau lawm, nws tuaj yeem yooj yim ua rau lub ntsej muag loj yam tsis muaj kev sib txuas sab hauv, tsim lub thoob zoo li cov duab, tsis tshua muaj neeg phem. Soldering yuav tsum cia li submerge tag nrho cov tivthaiv pins ntawm lub soldering point, thiab cov qauv yuav tsum faintly pom.
