Soldering hlau tsis lo rau tin - ua rau thiab kev daws teeb meem
Cov hlau soldering yog ib qho ntawm cov cuab yeej tsim nyog rau cov neeg siv khoom siv hluav taws xob vuam. Muaj ib tug zoo soldering hlau yuav pab tau peb weld thiab debug hluav taws xob circuits nrog ob zaug qhov tshwm sim nrog ib nrab ntawm kev siv zog, thiab tuaj yeem txhim kho kev ua haujlwm zoo. Txawm li cas los xij, cov phooj ywg uas nyuam qhuav kawm siv cov hlau soldering yuav muaj qhov kev paub no, uas yog, lub taub hau hlau tsis lo rau lub tin, thiab yuav pom tias cov tin molten sticks mus rau saum lub taub hau zoo li cov dej ntws. . Qee tus neeg mob hnyav dua yuav pom tias cov hlau nplaum tsis lo rau qhov kawg. Tsis tuaj yeem lo tin. Cov xwm txheej no ua rau peb muaj teeb meem loj thaum vuam cov khoom siv hluav taws xob, yog li yuav ua li cas tshem tawm qhov tshwm sim no? Niaj hnub no kuv yuav siv lo lus nug no los tham nrog kuv cov phooj ywg txog yuav ua li cas daws qhov teeb meem ntawm cov hlau taub hau tsis lo rau tin.
Qhov laj thawj yog vim li cas cov hlau taub hau tsis lo rau tin
Yog tias peb xav daws qhov teeb meem uas lub tshuab hluav taws xob soldering hlau tsis lo rau tin, peb yuav tsum xub to taub tias vim li cas hluav taws xob soldering hlau tsis lo rau tin. Peb cov phooj ywg uas siv hluav taws xob soldering irons txhua tus paub tias hluav taws xob soldering irons tau muab faib ua lub neej ntev taw tes thiab hom zoo tib yam soldering hlau taub. Rau lub neej ntev Lub taw tes-zoo li tus soldering hlau taub yog ib lub ntsiab lus hlau feem ntau yog tsim los ntawm tsib cov ntaub ntawv hlau: tooj liab, hlau, npib tsib xee, chromium, thiab tin; rau cov lus qhia zoo tib yam hluav taws xob soldering hlau, nws yog tsim los ntawm tooj liab liab lossis liab tooj liab. Tshwj xeeb npaj rau tooj liab, hlau thiab lwm yam hlau uas yooj yim oxidized thaum raug tshav kub. Lub oxidized soldering hlau taub yuav tsim ib txheej nyias ntawm oxidized hlau rau ntawm qhov chaw, uas yog ib qho nyuaj rau kev sib raug zoo nrog cov hlau molten. Qhov no yog qhov laj thawj tseem ceeb vim li cas lub taub hau hlau tsis lo rau tin.
Yuav ua li cas los daws qhov teeb meem ntawm soldering hlau taub tsis lo rau tin
Cia kuv qhia rau kuv cov phooj ywg seb kuv yuav ua li cas nrog cov lus qhia uas tsis yog-stick soldering hlau. Vim kuv feem ntau siv cov lus qhia hluav taws xob zoo tib yam. Thaum lub taub hau ntawm cov hlau tsis sib haum xeeb ntsib oxidation, kuv thawj kauj ruam yog ua cov ntaub ntawv ntawm cov hlau oxide nrog cov ntaub ntawv kom tshem tawm cov txheej nyias ntawm cov hlau oxide qhwv lub taub hau. Kom txog rau thaum tus tshiab tooj liab raug rau ntawm lub soldering hlau taub, ces tig lub hwj chim thiab tos kom txog thaum lub soldering hlau taub mus txog rau thaum tshav kub kub. Ntxiv ib co rosin. Thaum lub taub hau hlau ncav cuag qhov kub ntawm melting cov hlau, qhwv tag nrho cov hlau taub hau nrog ib txheej ntawm cov tin, kom cov hlau taub hau tau yooj yim "noj" cov tin. . Rau ib tug ntev-ntev taw tes soldering hlau, kuv xav kom polishing nws nrog sandpaper thiab siv tib txoj kev rau tin daim ntawv thov.
