Cov txheej txheem los txo cov oxidation tus nqi ntawm soldering hlau taub thiab soldering hlau core
1. Ntsuam xyuas qhov loj me
Ua ntej siv cov hlau soldering, ntsuas qhov tsis kam ntawm lub hwj chim ntsaws los txiav txim seb cov hlau puas siv tau.
Qhov kev tiv thaiv ntawm hluav taws xob soldering hlau yog ntau txhiab ohms, qhia tias nws siv tau. Yog tias qhov tsis kam yog xoom lossis infinite, nws siv tsis tau. Yog tias qhov tsis kam yog xoom, nws qhia tau hais tias muaj qhov luv luv hauv cov hlau soldering. Yog hais tias qhov kev tiv thaiv yog infinite, nws txhais tau hais tias muaj ib tug qhib Circuit Court nyob rau hauv lub soldering hlau.
2. Tin plating tiv thaiv
Thaum siv cov hlau soldering tshiab thawj zaug, xyuas kom meej tias lub hau ntawm cov hlau yog ci iab. Kub nws thiab yaj lub solder thaum dipping nws nyob rau hauv rosin. Tiv tauj cov hlau nplaum ntau zaus kom sib npaug ntawm lub hau nrog ib txheej ntawm cov solder. Nws tuaj yeem pab txhawb kev siv tom ntej thiab tiv thaiv oxidation ntawm cov hlau taub hau.
Cov qub soldering hlau tau siv ntev heev, thiab yuav muaj ib txheej ntawm oxide nyob rau saum npoo ntawm cov hlau taub hau, uas ua rau nws nyuaj rau cov hlau taub hau noj tin.
Cov oxide nyob rau saum npoo ntawm lub taub hau hlau tuaj yeem raug tshem tawm nrog cov ntawv xuab zeb zoo los yog cov ntaub ntawv kom nws lub ntsej muag ci. Tom qab ntawd, ua raws li txoj kev kho mob ntawm tus tshiab soldering hlau, tusyees lub tsho tiv no ntawm lub soldering hlau taub nrog ib txheej ntawm solder.
3. Qhov teeb meem ntawm soldering hlau tsis noj tin
Thaum ib tug soldering hlau ntsib teeb meem ntawm tsis noj tin, nws yog feem ntau tsis tsim nyog los txiav txim seb nws yog tshwm sim los ntawm tsis txaus oxygen. Cov pa oxygen tsis cuam tshuam rau cov cua sov ntawm cov hlau soldering, thiab cov hlau soldering heats thiab melts lub solder hlau los ntawm alternating tam sim no.
Hluav taws xob soldering hlau tsis noj tin vim yog tias nws tsis siv rau lub sijhawm ntev tom qab siv lub tshuab hluav taws xob, 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 hlau rau oxidize lossis hlawv tawm vim cua sov ntev.
Yog li ntawd, qhov teeb meem ntawm soldering hlau tsis noj tin tshwm sim. Thaum lub sij hawm tus txheej txheem ntawm tsis noj tin, oxidation tshwm sim, thiab cov tshuaj reacted chemically nrog oxygen, ntawm cov pa oxygen muab oxygen.
Thaum lub hwj chim ntawm lub sij hawm ntev dhau lawm thiab qhov kub thiab txias nce siab, muab cov kev mob tshwm sim rau cov tshuaj tiv thaiv oxidation yuav ua kom cov oxidation tus nqi ntawm cov hlau taub hau thiab cov tub ntxhais.
