Xyuas cov hluav taws xob soldering hlau ua ntej siv los tiv thaiv oxidation sai ntawm cov hlau taub hau
1. Test kuj loj
Ua ntej siv hluav taws xob soldering hlau, ntsuas qhov tsis kam ntawm lub hwj chim ntsaws los txiav txim seb cov hlau puas siv tau.
Qhov kev tiv thaiv ntawm ib qho hluav taws xob soldering hlau yog ntau txhiab ohms, qhia tias muaj. Yog tias qhov tsis kam yog xoom lossis infinite, nws siv tsis tau. Yog hais tias qhov tsis kam yog xoom, nws qhia tau hais tias luv luv Circuit Court nyob rau hauv lub soldering hlau, thiab yog hais tias tus kuj yog infinite, nws qhia tau hais tias ib tug qhib Circuit Court nyob rau hauv lub soldering hlau.
2. Siv tin plating tiv thaiv
Thaum lub tshuab hluav taws xob tshiab siv thawj zaug, lub taub hau hluav taws xob hluav taws xob yuav tsum tau ua kom ci. Lub soldering tin yuav tsum tau rhuab los ntawm hluav taws xob thiab dipped nrog rosin nyob rau tib lub sij hawm. Lub soldering hlau yuav tsum tau hu rau ntau zaus, thiab lub taub hau soldering hlau yuav tsum sib npaug zos coated nrog ib txheej ntawm soldering tin. Nws yog qhov yooj yim rau kev siv tom ntej thiab tuaj yeem tiv thaiv oxidation ntawm lub taub hau hlau.
Lub qub hluav taws xob soldering hlau tau siv ntev heev, thiab yuav muaj ib txheej ntawm oxide nyob rau saum npoo ntawm lub taub hau soldering, uas ua rau nws nyuaj rau lub taub hau soldering hlau noj tin.
Cov oxide nyob rau saum npoo ntawm lub taub hau hlau tuaj yeem raug tshem tawm nrog cov ntawv xuab zeb zoo lossis cov ntaub ntawv ua kom nws lub ntsej muag ci. Tom qab ntawd, raws li txoj kev kho mob ntawm tus tshiab hluav taws xob soldering hlau, tusyees tsho rau saum npoo ntawm lub taub hau soldering hlau nrog ib txheej ntawm vuam.
3. Qhov teeb meem ntawm hluav taws xob soldering hlau tsis noj tin
Thaum cov hlau nplaum tsis noj cov tin, feem ntau tsis tas yuav xav txog seb nws puas yog tshwm sim los ntawm cov pa oxygen tsis txaus. Oxygen tsis muaj dab tsi ua rau cov cua sov ntawm cov hlau soldering. Lub soldering hlau heats thiab melts lub solder hlau los ntawm alternating tam sim no.
Hluav taws xob soldering hlau tsis noj cov tin vim yog tias lawv tsis siv vim kev siv hluav taws xob ntev, nws yuav ua kom cov oxidation ntawm cov tub ntxhais hlau soldering thiab hlawv nws tawm, ua rau nws lub neej ua haujlwm ntev. Nyob rau tib lub sijhawm, nws tuaj yeem ua rau lub taub hau ntawm lub taub hau rau oxidize lossis hlawv vim cua sov ntev.
Qhov no tau ua rau muaj teeb meem ntawm hluav taws xob soldering hlau tsis noj tin. Thaum lub sij hawm tus txheej txheem tsis noj tin, oxidation tshwm sim tshwm sim, thiab cov tshuaj muaj tshuaj tiv thaiv nrog oxygen, uas muab oxygen.
Thaum lub hwj chim ntawm lub sij hawm ntev dhau lawm thiab qhov kub thiab txias nce siab, muab cov tshuaj tiv thaiv rau cov tshuaj tiv thaiv oxidation yuav ua rau kom cov oxidation ntawm lub taub hau thiab cov tub ntxhais.
