Txoj kev loj hlob ntawm cov hlau taub hau rau soldering thiab tinning
1. Kev nyab xeeb ntawm hluav taws xob soldering hlau
Ua ntej siv cov hluav taws xob soldering hlau, ua ntej siv ib lub multimeter los ntsuas qhov tsis kam ntawm ob qho kawg ntawm lub hwj chim ntsaws los txiav txim seb lub tshuab hluav taws xob puas tuaj yeem ua haujlwm li qub. Feem ntau, hluav taws xob
Qhov tsis kam ntawm cov hlau soldering yog ntau txhiab ohms ua ntej nws tuaj yeem siv tau. Muaj ob qhov xwm txheej txawv txav. Yog hais tias tus nqi kuj nyob ze rau xoom, tej zaum yuav muaj ib tug luv luv Circuit Court nyob rau hauv. Yog hais tias tus nqi kuj nyob ze rau infinity, lub internal circuit qhib. Soldering hlau nrog cov xwm txheej txawv txav tsis tuaj yeem siv. Qhov thib ob, siv cov ntaub ntawv tiv thaiv siab tshaj plaws los ntsuas qhov kev tiv thaiv ntawm lub hwj chim ntsaws thiab lub hau ntawm cov hlau soldering los txiav txim seb cov hlau puas muaj cov pa tawm. Nyob rau hauv ib txwm muaj, tus nqi kuj yog siab dua ob peb megohms mus rau infinity, txwv tsis pub nws yuav siv tsis tau. Thaum kawg saib cov hlau soldering
Tshawb xyuas cov xov hlau rau kev kub hnyiab thiab kev puas tsuaj, tshwj xeeb tshaj yog rau cov xov hlau uas raug tooj liab. Kev kub nyhiab me me, tsis tas yuav tsum muaj kev kho mob ntev li ntev tau yog tias tsis muaj cov xaim tooj liab raug nthuav tawm Yog tias tus neeg xyuas pib tau raug tooj liab
, Koj tuaj yeem siv cov ntaub nplaum insulating los kho cov rwb thaiv tsev. Yog tias ob lub xov hlau tau nthuav tawm cov xov tooj tooj liab, lawv yuav tsum tau muab sib cais kom rov qab rwb thaiv tsev, thiab tom qab ntawd ntxiv txheej rwb thaiv tsev rau sab nraud. Soldering hlau nrog faulty hlau tsis tuaj yeem siv, txwv tsis pub.
Kev kho ntawm cov hlau taub hau ua ntej siv
Kev kho ntawm cov hlau taub hau ua ntej siv
Kev tuav ntawm cov hlau nplaum tshiab ua ntej siv thawj zaug Cov hlau soldering tshiab tsis tuaj yeem siv tam sim ntawd. Ua ntej yuav siv ib tug tshiab soldering hlau, xyuas seb lub ntsis ntawm lub soldering hlau yog huv si. Yog tias muaj av, ntxuav nws nrog daim txhuam cev ntub dej ua ntej. Yog tias nws loj heev, siv cov ntawv xuab zeb zoo tshem tawm cov av ntawm qhov kawg ntawm cov hlau soldering kom lub taub hau ci thiab tom qab ntawd tig nws thiab kub kom txog thaum nws tuaj yeem yaj lub solder. Tom qab dipping nyob rau hauv rosin, kov nws nrog lub ntsis ntawm lub soldering hlau rau ntau zaus Solder hlau, thiaj li hais tias lub ntsis ntawm lub soldering hlau yog tusyees coated nrog ib tug txheej ntawm tin. Tom qab qhov kev kho mob no, nws tsis yog tsuas yog yooj yim rau yav tom ntej welding, tab sis kuj tiv thaiv oxidation nto ntawm soldering hlau taub.
. Kev kho mob ntawm cov laus soldering hlau taub hau ua ntej siv Tom qab cov hluav taws xob soldering hlau yog siv rau lub sij hawm ntev, ib txheej ntawm oxide yuav tsim nyob rau hauv lub ntsis ntawm lub soldering hlau, thiab cov soldering hlau yuav tsis yooj yim rau noj tin. Txoj hauv kev los daws nws yog tshem tawm cov oxide txheej nrog cov ntawv xuab zeb zoo lossis cov ntaub ntawv kom nthuav tawm cov xim hlau. Tom qab cua sov, dip nws nyob rau hauv rosin rau re-tinning los yog tshem tawm cov oxide txheej, ces muab lub rhuab soldering hlau taub hau rov qab mus rau hauv cov khoom sib xyaw nrog rosin thiab solder RUB kom txog rau thaum lub taub hau ntawm lub soldering hlau taub yog coated nrog ib txheej ntawm tin.
