Taw qhia rau cov txheej txheem ua haujlwm ntawm hluav taws xob soldering hlau phau ntawv vuam
1. Tshawb xyuas ua ntej ua haujlwm
(1) Tshawb xyuas qhov kub taub hau
Ntxig lub ntsaws ntawm lub tshuab hluav taws xob rau hauv lub qhov (socket) 3-5 feeb ua ntej mus ua haujlwm txhua hnub, thiab xyuas seb cov hlau nplaum puas kub. Yog tias nws tsis kub, ua ntej xyuas seb lub qhov (socket) puas yog ntsaws rau hauv. Tsis txhob disassemble lub soldering hlau ntawm lub siab nyiam, cia nyob ib leeg ncaj nraim kov lub taub hau ntawm koj txhais tes.
(2) Hloov kho lub taub hau hlau hauv lub sijhawm
Oxidized bumpy los yog hooked tswv yim yuav tsum tau hloov nrog:
1. Ua kom muaj txiaj ntsig zoo thaum tshav kub kub ua haujlwm;
2. Los xyuas kom meej qhov zoo ntawm cov khoom welded.
Yog hais tias ib tug tshiab soldering hlau taub yog hloov, cov xim tu yuav tsum tau muab tshem tawm tom qab cua sov, thiab tin nkawm yuav tsum tau ntxiv tam sim ntawd.
Kev ntxuav ntawm cov hlau soldering yuav tsum tau ua ua ntej ua haujlwm soldering. Thaum cov hlau tsis siv ntau tshaj 5 feeb, lub hwj chim yuav tsum muab tua.
(3) Xyuas seb lub tin absorbing daim txhuam cev puas muaj dej thiab huv
Yog tias tsis muaj dej, thov ntxiv cov dej uas tsim nyog (tus nqi tsim nyog txhais tau hais tias cov dej ntws tawm thaum daim txhuam cev nias rau ib nrab ntawm nws cov tuab tuab.
Txoj kev ua haujlwm: Cov kev xav tau av noo Tom qab daim txhuam cev ntub tag, tuav nws hauv xib teg ntawm koj txhais tes thiab kaw koj tsib ntiv tes ib txwm muaj.
Thaum siv cov hlau soldering rau phau ntawv soldering, daim txhuam cev siv yuav tsum tau ntxuav. Daim txhuam cev qias neeg muaj cov khoom siv hlau, los yog cov ntaub txhuam hniav uas muaj cov tshuaj sulfur yuav ua rau lub taub hau ntawm cov hlau soldering puas.
(4) Txawm hais tias tib neeg lub cev thiab cov hlau soldering muaj kev ntseeg siab, thiab seb tib neeg lub cev hnav lub nplhaib electrostatic.
Soldering hlau kauj ruam
1. Preheating: Lub taub hau ntawm cov hlau soldering yog ntawm 45- lub kaum sab xis, thiab nws tiv taus cov ntaub qhwv thiab cov ko taw.
Pre-heat lub tivthaiv pins thiab pads. Lub taub hau ntawm lub taub hau hlau yuav tsum tsis txhob sawv ntawm qhov tsis muaj tooj liab ntawm PCB, yog li tsis txhob hlawv lub rooj tsavxwm rau hauv ib qho kab; Lub taub hau hlau yuav tsum ua raws li cov kev taw qhia ntawm lub voj voog: lub taub hau ntawm lub taub hau yuav tsum tsis txhob thaiv qhov ntawm lub qhov: lub sij hawm ua ntej yog 1 mus rau 2 vib nas this.
2. Tinning: Qhia cov tin hlau los ntawm kev sib cuag ntawm ko taw thiab cov hlau soldering; thaum lub tin hlau melts, master lub ceev ntawm cov hlau; thaum lub tin tau tawg thoob plaws hauv lub ncoo, tshem tawm cov tin hlau; lub tin hlau tsis tuaj yeem ncaj qha rau ntawm lub taub hau ntawm lub taub hau txhawm rau tiv thaiv kom tsis txhob kub hnyiab dub; tag nrho tinning lub sij hawm yog hais txog 1 mus rau 2 vib nas this.
3. Tshem cov tin hlau: tshem cov tin hlau, thiab muab tso rau ntawm lub ncoo; lub sij hawm yog li ntawm 1 mus rau 2 vib nas this.
4. Tshem tawm cov hlau soldering: Thaum tsuas yog cov pa taws me ntsis tawm ntawm lub vuam, koj tuaj yeem tshem cov hlau soldering kom khov kho cov pob qij txha.
