Cov lus qhia thiab qhov tseem ceeb rau kev sib tsoo hlau hlau
Manual welding txheej txheem:
1. Kev tshuaj xyuas ua ntej ua haujlwm
(1) 3-5 feeb ua ntej welding, ntxig cov hluav taws xob soldering hlau ntsaws rau hauv lub qhov (socket) thiab xyuas seb cov hlau puas muaj cua sov. Yog tias nws tsis kub, ua ntej xyuas seb lub qhov (socket) puas yog ntsaws rau hauv. Yog tias nws tau ntsaws rau hauv kom zoo, thiab yog tias nws tseem tsis sov, ceeb toom rau tus thawj coj tam sim ntawd. Tsis txhob disassemble lub soldering hlau ntawm lub siab nyiam, thiab tsis txhob kov lub taub hau ntawm koj txhais tes ncaj qha
(2) Lub oxidized, tsis sib npaug los yog hooked soldering hlau taub yuav tsum tau hloov kho: 1. Nws tuaj yeem ua kom muaj kev ua kom sov zoo; 2. Xyuas kom zoo ntawm cov khoom siv welded. Yog hais tias ib tug tshiab soldering hlau taub yog ntsia, cov xim tu yuav tsum tau muab tshem tawm thiab tin yuav tsum tau ntxiv tam sim ntawd rau kev kho tom qab rhuab. Kev ntxuav ntawm cov hlau soldering yuav tsum tau ua ua ntej soldering ua haujlwm. Yog tias cov hlau tsis siv ntau tshaj 5 feeb, lub hwj chim yuav tsum muab tua. Daim txhuam cev yuav tsum tau ntxuav kom huv si. Daim txhuam cev uas muaj cov hlau los yog cov tshuaj muaj sulfur tuaj yeem ua rau lub taub hau hlau puas.
(3) Xyuas seb lub tin daim txhuam cev puas muaj dej thiab huv. Yog tias tsis muaj dej, ntxiv cov dej uas tsim nyog (tus nqi tsim nyog yog hais txog cov dej ntws tawm thaum lub sponge nias rau ib nrab ntawm cov tuab tuab. Cov haujlwm tshwj xeeb yog: tom qab daim txhuam cev ntub dej tag, tuav nws hauv xib teg ntawm koj txhais tes, thiab tsib ntiv tes yuav tsum tau kaw). Daim txhuam cev yuav tsum tau ntxuav kom huv si. Cov sponges tsis huv uas muaj cov khoom hlau los yog cov ntaub txhuam hniav uas muaj cov tshuaj sulfur tuaj yeem ua rau lub taub hau hlau ua puas tsuaj.
(4) Puas yog tib neeg lub cev muaj kev ntseeg siab rau cov hlau nplaum, thiab yog tib neeg lub cev hnav lub nplhaib electrostatic.
2. Vuam cov kauj ruam
Cov kauj ruam ua haujlwm tshwj xeeb ntawm cov hlau tuaj yeem muab faib ua tsib kauj ruam, hu ua tsib kauj ruam engineering txoj kev. Yuav kom ua tiav qhov zoo vuam zoo, nws yog ib qho tsim nyog yuav tsum ua raws li tsib txoj haujlwm uas qhia hauv daim duab hauv qab no.
Ua raws li cov kauj ruam saum toj no rau vuam yog ib qho ntawm cov yuam sij kom tau txais cov pob qij txha zoo. Nyob rau hauv qhov tseeb ntau lawm, feem ntau ua txhaum ntawm kev khiav hauj lwm cov txheej txheem yog hais tias lub taub hau ntawm soldering hlau tsis yog thawj zaug los rau hauv kev sib cuag nrog lub workpiece yuav tsum tau welded, tab sis ua ntej los rau hauv kev sib cuag nrog lub solder hlau. Lub melted solder tee poob rau ntawm qhov preheated qhov yuav tsum tau welded, uas yooj yim ua rau solder sib koom tsis ua hauj lwm. Yog li ntawd, lub taub hau hlau yuav tsum tuaj rau hauv kev sib cuag nrog lub workpiece yuav tsum tau welded, thiab preheating lub workpiece yog ib qho tseem ceeb txhais tau tias los tiv thaiv tsis ua hauj lwm.
3. Vuam qhov tseem ceeb
Txoj kev sib cuag ntawm lub taub hau hlau soldering thiab ob qhov chaw soldered
Kev sib cuag txoj hauj lwm: Lub taub hau hlau soldering yuav tsum ib txhij hu rau ob qhov chaw uas yuav tsum tau txuas rau ib leeg (xws li cov ko taw thiab cov ntaub qhwv). Cov hlau soldering feem ntau inclined ntawm lub kaum sab xis 45 degree, thiab nws yuav tsum tau zam kom tsuas yog tiv tauj ib qho ntawm cov khoom siv. Thaum muaj qhov sib txawv ntawm qhov muaj peev xwm kub ntawm ob qhov chaw welded, lub kaum sab xis ntawm cov hlau yuav tsum tau kho kom haum. Qhov me me qhov qaij lub kaum sab xis ntawm cov hlau soldering thiab vuam nto, qhov loj ntawm qhov chaw sib cuag ntawm qhov chaw welded nrog lub peev xwm loj dua thiab cov hlau soldering, thiab qhov muaj zog ntawm cov cua sov conductivity. Thaum LCD yog soldered, lub kaum sab xis yog nyob ib ncig ntawm 30 degrees, thiab thaum soldering microphones, motors, hais lus, thiab lwm yam., lub qaij lub kaum sab xis yuav nyob ib ncig ntawm 40 degrees. Ob qhov chaw welded uas tuaj yeem ncav cuag qhov kub thiab txias nyob rau tib lub sijhawm yog suav tias yog nyob rau hauv qhov zoo tagnrho cua sov.
Kev sib cuag siab: Thaum lub taub hau hlau soldering los rau hauv kev sib cuag nrog lub workpiece, yuav tsum tau siv lub siab me ntsis. Lub zog ntawm thermal conduction yog proportional rau qhov loj ntawm lub siab thov, tab sis lub hauv paus ntsiab lus yog kom tsis txhob ua kev puas tsuaj rau saum npoo ntawm workpiece.
