Txoj kev siv cov hlau soldering rau solder chip Cheebtsam
Vuam Cheebtsam
Ua ntej hloov cov khoom tshiab, xyuas kom meej tias cov ntaub so ntswg huv si. Ua ntej siv cov tin rau ntawm ib kawg ntawm cov ntaub qhwv ntsej muag (tsis txhob siv cov tin ntau dhau), tom qab ntawd clamp cov khoom siv nrog tweezers, solder ib kawg ntawm cov ntaub qhwv lub taub hau ua ntej, thiab tom qab ntawd txuas rau lwm qhov kawg. , thiab thaum kawg siv cov tweezers los txhim kho cov khoom, thiab phaj ob qhov kawg ntawm cov khoom siv nrog tus nqi tsim nyog ntawm tin rau trimming.
Disassemble cov khoom
Yog tias tsis muaj ntau cov khoom nyob ib puag ncig, koj tuaj yeem siv cov hlau nplaum los ua kom sov ob qhov kawg ntawm cov khoom siv rau 2 mus rau 3 vib nas this thiab tom qab ntawd txav mus sai sai rau ob qho tag nrho ntawm cov khoom. Nyob rau tib lub sijhawm, tes tuav cov hlau nplaum tuaj yeem raug thawb mus rau ib sab nrog lub zog me me kom tshem tawm nws. cov khoom. Yog tias cov khoom nyob ib puag ncig yog tuab, koj tuaj yeem siv koj txhais tes laug los tuav lub ntsis ntawm cov tweezers kom maj mam pinch nruab nrab ntawm cov khoom. Siv ib tug soldering hlau kom tag nrho yaj lub tin ntawm ib kawg thiab sai sai txav mus rau lwm qhov kawg ntawm cov khoom. Nyob rau tib lub sijhawm, nqa nws nrog koj txhais tes sab laug me ntsis, yog li ntawd thaum lub tin ntawm ib kawg yog Thaum nws yog tag nrho melted tab sis tseem tsis tau solidified thiab lwm kawg yog melted, koj muaj peev xwm tshem nws nrog tweezers nyob rau hauv koj sab laug. tes.
Cia peb tham luv luv txog yuav ua li cas yog tias muaj ib qho luv luv thaum lub sij hawm soldering nrog cov hlau lead solder paste?
Thawj qhov uas yuav tsum tau xav txog yog seb puas muaj qhov seem seem ntawm PCB, yog li koj yuav tsum xub txiav txim siab seb puas muaj cov dej xau thaum siv cov khoom siv nrog cov hlau lead.
Tom qab drilling thiab soldering PCB, koj puas ntxuav nws? Yog tias cov dej xau tshwm sim, nws yuav yog vim muaj ntau yam.
1. Yog tias lub rooj tsav xwm PCB tawg, nws tus kheej tau luv luv. Txog qhov no, kev sim ua ntej tuaj yeem ua tau ua ntej siv lub rooj tsavxwm PCB.
2. Nws tsis tau ntxuav. Tsis tas li ntawd, nws yuav tsum tau qhia meej seb tus neeg saib xyuas siv yuav ua rau corrosion los yog tawm hauv seem.
Cov pob qij txha ntawm lub rooj tsavxwm PCB yuav tsum tsis txhob nyob ze dhau, thiab qhov zaus ntawm cov khoom siv hluav taws xob ntawm cov pob qij txha kuj tseem yog ib qho tseem ceeb uas yuav tsum tau xav txog kev xau.
Thaum cov pob qij txha tau sib sau ua ke los yog qhov zaus ntawm kev siv zog ntawm cov pob qij txha yog siab heev, txhawm rau kom tau txais cov txiaj ntsig zoo tshaj plaws, nws raug nquahu kom siv cov hlau tsis muaj hlau lead lossis rosin-core solder hlau, thiab ntxuav nws tom qab. lub soldering tiav.
Cov dej xau tuaj yeem cuam tshuam nrog kev rwb thaiv tsev ntawm cov khoom siv hluav taws xob nws tus kheej. Qhov me me ntawm rwb thaiv tsev tsis kam ntawm cov khoom siv hluav taws xob, qhov ntau dua qhov muaj peev xwm ntawm to. Lub rwb thaiv tsev tsis kam ntawm ntau hom txhuas solder pastes sib txawv vim muaj cov neeg ua haujlwm sib txawv hauv lawv.
