Cov lus piav qhia ntxaws txog kev ua haujlwm ntawm plaub txoj kev vuam thaum lub sij hawm vuam
1. Txoj kev suction thiab soldering
Los ntawm kev siv lub siab tsis zoo ntawm cov kab noj hniav ntawm cov khoom siv hauv cov khoom siv, cov rhuab thiab melted solder yog nqus mus rau hauv cov kab noj hniav, cais cov hlau lead ntawm cov ntaub qhwv.
2. Txoj kev soldering rau tshem tawm tin suction ropes
Tus txheej txheem ntawm kev tshem tawm solder los ntawm lub solder ncoo los ntawm kev siv ib tug suction hlau yog cais cov hlau lead ntawm lub solder ncoo los ntawm kev siv lub suction hlau los tshem tawm molten solder.
Siv rosin flux mus rau ib feem ntawm cov hlau braided, tom qab ntawd muab tso rau ntawm qhov sib koom ua ke kom tau soldered, thiab tom qab ntawd muab ib qho hluav taws xob soldering hlau rau ntawm cov hlau braided kom sov cov khoom sib txuas. Tom qab lub solder ntawm lub solder sib koom melts, nws yog absorbed los ntawm tooj liab braided hlau.
Yog hais tias lub solder ntawm lub solder sib koom yog tsis nqus tag nrho ib zaug, ib tug thib ob los yog thib peb lub sij hawm yuav nqa tawm mus txog rau thaum nws yog absorbed tag. Thaum txoj hlua Dynamic yog tag nrho ntawm cov tin, nws tsis tuaj yeem siv dua, thiab qhov chaw uas tag nrho ntawm cov solder yuav tsum raug txiav tawm.
3. luv koob vuam txoj kev
Txoj kev siv rab koob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Thaum cov hluav taws xob soldering hlau heats li lub soldering tin thiab melts, ceev ceev tig lub koob kom txog thaum lub soldering hlau raug tshem tawm thiab cov soldering tin solidifies ua ntej nres. Lub sijhawm no, rab koob raug rub tawm thiab cov hlau lead tau raug cais tawm.
4. Tshem tawm soldering nrog ib tug tin absorbing soldering hlau
Tin absorbing hluav taws xob soldering hlau yog ib hom tshwj xeeb ntawm cov hlau uas tuaj yeem ua kom sov lub vuam sib txuas thiab nqus cov tin rau hauv cov kab noj hniav kom tiav cov txheej txheem soldering.
Thaum siv hluav taws xob soldering hlau thawj zaug, muaj plaub kauj ruam me me ua raws.
1. Preheating: Lub taub hau hlau yog nyob ntawm 45 degree lub kaum sab xis, nias tiv thaiv cov ntaub qhwv thiab cov ko taw.
Preheat cov khoom taw qhia thiab cov ntaub qhwv. Lub taub hau ntawm lub taub hau hlau tsis tuaj yeem txhawb txoj haujlwm yam tsis muaj daim ntawv tooj liab ntawm lub rooj tsavxwm PCB kom tsis txhob hlawv lub rooj tsavxwm rau hauv ib lub cim; Lub taub hau hlau yuav tsum zoo dua nyob rau hauv cov kev taw qhia ntawm lub voj voog: lub taub hau hlau yuav tsum tsis txhob thaiv lub qhov los ntawm qhov: lub sij hawm ua ntej yog 1-2 vib nas this.
2. Tin loading: Qhia cov tin hlau los ntawm qhov chaw sib cuag ntawm ko taw thiab cov hlau soldering; Thaum lub tin hlau melts, tswj cov khoom ceev; Thaum lub tin puv tag nrho cov ntaub qhwv, tshem tawm cov tin hlau; Lub tin hlau tsis tuaj yeem muab tso ncaj qha rau ntawm lub taub hau ntawm lub taub hau kom tsis txhob muaj qhov kub hnyiab ntawm cov xim dub; Lub sijhawm thauj khoom tag nrho yog kwv yees li 1-2 vib nas this.
3. Tshem tawm cov tin hlau: Tshem cov tin hlau thiab muab lub cub tawg txuas ntxiv rau ntawm cov ntaub qhwv; Lub sij hawm yog kwv yees li 1-2 vib nas this.
4. Tshem tawm cov hlau soldering: Thaum tsuas muaj cov pa taws me ntsis tawm ntawm cov hlau soldering, cov hlau tuaj yeem raug tshem tawm kom ua kom cov khoom sib txuas.
