Cov ntsiab lus ua haujlwm ntawm hluav taws xob soldering hlau
Weldment nto kho
Ntau yam khoom siv hluav taws xob thiab cov xov hlau uas tau ntsib hauv cov khoom siv hluav taws xob feem ntau yuav tsum tau ntxuav qhov chaw ua ntej vuam, raws li qhia hauv daim duab, tshem tawm xeb, roj, plua plav thiab lwm yam impurities ntawm vuam nto uas cuam tshuam rau vuam zoo. Tej yam yooj yim thiab yooj yim txoj kev xws li mechanical scraping thiab sib tsoo yog feem ntau siv nyob rau hauv phau ntawv ua haujlwm.
Soldering hlau taub ntxuav thiab "noj tin"
Thaum soldering, lub taub hau hlau yog nyob rau hauv qhov kub thiab txias rau lub sijhawm ntev, thiab nws raug rau cov khoom cua sov-decomposed xws li flux, thiab saum npoo yog yooj yim oxidized los tsim ib txheej ntawm cov impurities dub. Cov impurities no yuav luag tsim ib txheej rwb thaiv tsev kub thiab ua rau cov hlau taub hau poob nws cov cua sov. Yog li ntawd, nws yog ib qho tsim nyog yuav tau txhuam cov impurities ntawm cov hlau thav duab txhua lub sijhawm. Nws kuj yog ib txoj hauv kev los so lub ntsis ntawm cov hlau nplaum nrog ib daim ntaub ntub dej los yog daim txhuam cev ntub dej txhua lub sijhawm. Tom qab ntxuav, lub taub hau ntawm cov hlau yuav tsum tau wetted los ntawm solder, uas yog, lub taub yuav tsum tau them nrog ib txheej ntawm solder, feem ntau hu ua "noj tin". Pab tau thaum.
ua ntej soldering
Pre-soldering yog ua ntej ntub cov vuam qhov chaw ntawm cov khoom siv los yog cov xov hlau los ua cov hlau, los yog hu ua tinning. Nws yog yuav luag indispensable rau phau ntawv soldering hlau welding, tshwj xeeb tshaj yog rau debugging thiab txij nkawm nyob rau hauv cov khoom tsim ua hauj lwm.
Tsib-kauj ruam kev cob qhia txoj kev rau hluav taws xob soldering hlau
Txoj kev tsib kauj ruam yog summed los ntawm cov predecessors. Nws tau raug pov thawj tias ua tau zoo nyob rau hauv kev xyaum raws li ib tug phau ntawv qhia soldering txoj kev. Xyaum soldering hlau vuam thiab txhim kho cov txheej txheem ntawm txoj kev tsib kauj ruam.
① Npaj rau vuam. Npaj solder hlau thiab soldering hlau. tshwj xeeb rau lub sijhawm no
Nws tau hais meej tias qhov ntxeev ntawm cov hlau yuav tsum tau ua kom huv si, uas yog, nws tuaj yeem raug stained nrog solder, feem ntau hu ua noj tin.
Cov hlau nplaum ua kom sov txhua qhov ntawm cov vuam, xws li cov hlau lead thiab cov ntaub qhwv rau ntawm cov ntawv luam tawm, kom sov lawv.
③ Qhuav lub solder. Thaum lub vuam yog rhuab mus rau ib tug kub uas melts lub solder, cov hlau yog muab tso rau ntawm lub solder sib koom, thiab cov solder pib yaj thiab ntub lub solder sib koom.
④ Tshem tawm lub solder. Thaum ib tug npaum li cas ntawm solder yog melted, lub solder
Hlau tshem tawm.
⑤ Tshem tawm cov hlau nplaum. Tshem lub solder thaum lub solder tau tag nrho wetted lub solder sib koom
Hlau Nco ntsoov tias cov kev taw qhia kom tshem tawm cov hlau soldering yuav tsum yog cov kev taw qhia dav dav, thiab qhov ceev ntawm kev tshem tawm yuav tsum txiav txim siab thiab ceev.
