tshiab soldering hlau kho ua ntej siv
Ib tug tshiab soldering hlau tsis tuaj yeem siv tam sim ntawd. Lub hau ntawm cov hlau soldering yuav tsum tau kho ua ntej nws tuaj yeem siv tau ib txwm. Uas yog hais tias, lub ntsis ntawm cov hlau soldering yuav tsum tau coated nrog ib txheej ntawm solder ua ntej siv. Cov txheej txheem tshwj xeeb yog: ua ntej siv cov ntaub ntawv los ua cov ntaub ntawv ntawm lub taub hau ntawm cov hlau soldering rau hauv ib qho kev xav tau, tom qab ntawd txuas lub hwj huam mov, thaum qhov kub ntawm qhov taub ntawm cov hlau soldering nce mus rau qhov chaw uas nws tuaj yeem yaj cov tin, Siv rosin rau ntawm qhov kawg ntawm cov hlau soldering, thiab tom qab ntawd siv nws tom qab rosin haus luam yeeb. Thov ib txheej ntawm solder, thiab ua qhov no ob mus rau peb zaug, kom lub ntsej muag ntawm lub taub hau ntawm lub taub hau yog tag nrho nrog ib txheej ntawm tin thiab nws tuaj yeem siv tau.
Thaum cov hlau nplaum siv rau ib lub sijhawm, cov oxide zaj duab xis yuav raug tsim rau ntawm cov hniav ntawm cov hlau taub hau thiab nws qhov chaw, uas yuav ua rau nws nyuaj rau "noj tin". Lub sijhawm no, cov yeeb yaj kiab oxide tuaj yeem raug tshem tawm thiab rov plated nrog solder.
Kho qhov ntev ntawm lub taub hau soldering
Tom qab xaiv lub hwj chim ntawm lub taub hau hlau, nws tau ua raws li qhov xav tau ntawm qhov kub thiab txias, tab sis nws tseem tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom nruab rau hauv lub rooj tsav xwm luam tawm. Piv txwv li, thaum welding integrated circuits thiab transistors, qhov kub ntawm lub soldering hlau taub yuav tsum tsis txhob siab dhau, thiab lub sij hawm yuav tsum tsis txhob ntev dhau. Nyob rau lub sijhawm no, qhov ntev ntawm cov hlua hlau ntxig ntxig rau ntawm cov tub ntxhais hlau soldering tuaj yeem hloov kho kom zoo los tswj qhov kub ntawm cov hlau taub hau.
Kev xaiv ntawm cov hlau taub hau
Muaj ob hom ntawm cov lus qhia ntawm cov hlau: ncaj taub hau thiab lub luj tshib. Thaum siv tus cwj mem tuav txoj kev, cov hluav taws xob soldering hlau nrog lub taub ncaj yog hloov tau yooj yim dua rau kev siv thiab tsim nyog rau soldering hauv circuits nrog ntau yam khoom. Nws yog tsim nyog los tuav cov hluav taws xob soldering hlau nrog nkhaus hlau taub hau, thiab nws yog feem ntau siv rau soldering thaum lub Circuit Court board yog ntsug rau lub desktop.
Tiv thaiv "noj tin"
Nws tsis yooj yim rau kev siv lub zog ntawm cov hlau ntev ntev yam tsis siv nws, vim nws yooj yim rau oxidation ntawm cov tub ntxhais hlau soldering thiab hlawv nws tawm, thiab nws tseem yuav ua rau cov hlau taub hau oxidize vim cua sov ntev. , thiab txawm yuav "hlwb tuag" thiab tsis "noj tin".
Hloov cov Soldering Hlau Core
Thaum hloov cov tub ntxhais hlau soldering, yuav tsum ceev faj tsis txhob txuas qhov tsis ncaj ncees lawm, vim hais tias cov hluav taws xob soldering hlau muaj peb lub terminals, ib qho yog grounded, thiab ob qho tib si txuas nrog ob lub taub hau ntawm cov tub ntxhais hlau soldering (ob lub terminals no. txuas ncaj qha mus rau 220 los ntawm txoj hlua hluav taws xob, txuas nrog lub volt AC fais fab mov). Yog tias 220-volt AC fais fab qaum txuas tsis raug rau txoj hlua khi hauv av, lub plhaub hluav taws xob hluav taws xob yuav raug them, thiab nws tseem yuav raug them thaum raug welded, kom muaj kev sib tsoo hluav taws xob. .
Xaiv Flux
Thaum soldering ib qho hluav taws xob soldering hlau, nws yog qhov zoo tshaj plaws los siv rosin flux los tiv thaiv cov hlau taub hau los ntawm corrosion. Zinc oxide thiab acidic solder roj yog ntau corrosive rau lub soldering hlau taub, uas yuav luv luv lub neej ntawm lub soldering hlau taub, yog li ntawd lawv tsis nquag siv.
