Kev tuav cov phom sij thiab lub disassembly ntawm thaj thaj

Nrog rau cov cuab yeej saum toj no, nws tsis yog nyuaj rau laug thiab tshem tawm cov thaj thaj. Rau cov khoom uas tsuas muaj 2 - 4 taw, xws li cov resistors, capacitors, diodes, triodes, thiab lwm yam, thawj phaj tin rau ntawm ib qho ntawm cov pawm ntawm PCB, ces muab sab tes laug nrog cov kab lus tso cov khoom thiab tso nws tawm tsam lub rooj tsavxwm. Txoj cai txhais tes muag cov pins ntawm lub ncuav nrog cov hlau hnyav. Tom qab kev tivthaiv welded rau ib tug ko taw, nws yuav tsis tsiv. Cov laug tes laug yuav raug loosened, thiab cov xov hlau ntxiv yog siv cov hlua khi. Nws kuj yog ib qho yooj yim heev los rhuav tshem tej yam zoo li no. Cia li siv ob lub phom laug (ib qho rau txhua tus sab laug thiab sab tes) kom sov hnub nyoog ob qho tib si ntawm tus tswv cuab tib lub sijhawm. Tom qab cov tin melted, lub Cheebtsam yuav raug tshem tawm los ntawm maj mam nqa lawv.

Rau tej thaj chaw uas muaj ntau lub pins tab sis qhov dav nrawm (xws li ntau yam zoo li SO nrog hom pins ntawm 6 thiab 20 thiab ib lub suab ntawm 1.27mm), ib qho kev ua zoo sib xws yog siv. Tin-plated, ces sab laug tes yog welded nrog ib tug khub ntawm tus tweezers rau khi ib txhais ko taw, thiab tom qab ntawd ces tshuav ntxiv yog cov laug nrog cov tin. Lub disassembly ntawm tej cheebtsam no feem ntau zoo dua nrog rau cov phom kub, siv phom kub ntawm lub tshuab siv tes, thiab lwm tus tes tshem tawm kev tivthaiv nrog lub clamp xws li lub caws pliav.

Rau cov khoom uas muaj siab ntiv tes (xws li 0.5 hli suab), lub kauj ruam zoo yog zoo li ntawd, uas yog, kauj ruam thawj kauj ruam, ces txhais tau tias cov ceg ntxiv uas muaj plaster. Txawm li cas los, rau tej yam khoom, vim hais tias cov pins yog tus loj thiab ntom, cov kev sib tw ntawm cov pins nrog cov pawm tseem ceeb heev. Tom qab tinning ib lub ncoo (feem ntau yog lub ncoo ntawm lub ces kaum, tsuas yog ib qho me me ntawm tin plated), dlhos lub nraub qaum nrog lub hauv ncoo nrog lub ncau lossis tes, kev saib xyuas kom zoo txhua yam pins nrog lub koob (ntawm qhov tseem ceeb tshaj plaws yog ua siab ntev!), tom qab ntawd ces nyem rau ntawm PCB nrog me ntsis kev siv zog (los yog los ntawm tweezers), thiab khawm tus pin coj rau sab tes xis nrog ib tus kav hlau. Tom qab laug, laug tes yuav loosened, tab sis tsis txhob nchuav rau pawg thawj coj, tab sis maj mam tig mus khi rau lub khob rau ntawm qhov chaw seem ntawm thawj. Thaum twg plaub lub kaum pob zeb tau txua tau, lub Cheebtsam yuav tsis txav hlo li, thiab cov pins ntxiv yuav tsum tau ib leeg los ntawm ib qho. Thaum welding, koj tuaj yeem ua ntawv thov qee cov khaub noom loose, cia cov hlau taub nrog ib qho me me ntawm tin, thiab siv ib tus pin ib zaug. Yog tias koj ua luv luv rau ntawm ob sab ko taw, tsis txhob txhawj xeeb, tos kom txog thaum txhua tus ciav hlau ua tiav, tom qab ntawd siv txoj hau kev los ntxuav cov tin. Ntawm chav kawm, kev paub txog cov kev txawj ntse no yuav tsum xyaum ua. Yog hais tias muaj ib lub rooj sib tham qub qub, tus qub IC kuj yuav raug siv rau kev xyaum.

Rau qhov kev tshem tawm ntawm cov koob ntim ntawm tus cwj pwm thiab BGA chips, cov cua kub phom mas yog siv, thiab cov cua kub phom raug kho txog li 300 degrees los tshuab tag nrho cov pins sab nrauv, thiab cov khoom yog nyhav thaum lawv tawg lawm. Yog tias qhov tshem tawm no tseem yuav tsum tau, ces sim tsis txhob tig mus rau lub ntsej muag ntawm qhov khoom thaum tshuab raj, thiab lub sijhawm yuav tsum luv li sai tau. Tom qab tshem cov khoom, ntxuav cov pawm nrog ib cov kav hlau. Yog tias koj tsis paub tseeb txog koj tus kheej, koj tuaj yeem nrhiav tau tus kws ua haujlwm hluav taws xob Deng Gong los pab.
