Yog tias koj koom nrog rau hauv cov khoom siv hluav taws xob thiab / lossis kho cov khoom siv hluav taws xob, tom qab ib ntus koj yuav tsum cuam tshuam nrog qhov yuav tsum tau muag cov SMD microcircuits. Tus txheej txheem no yuav tsum tau ua tib zoo ua ntej kom tsis txhob ua rau lub cuab yeej puas. Yuav kom daws tau qhov teeb meem no, ib txoj kev paub tau tuaj yeem xaiv.
Tsim nyog
- - soldering hlau;
- - Cov phom cua kub;
- - tweezers.
Cov Lus Qhia
Kauj ruam 1
Siv lub braid thiab tshem cov tin tshaj ntawm ob txhais ceg ntawm SMD nti. Siv ib txoj hlua hlau tsawg dua 0.3 hli hauv lub taub. Yog tias koj tsis muaj ib qho, tom qab ntawd koj tuaj yeem sau tau yooj yim muab cov xaim hlau tso rau hauv nws cov khoom sib cais. Tom ntej no, thawb cov hlau no nyob hauv qab ntawm ceg ntawm lub microcircuit, uas yuav tsum tau yaj.
Kauj ruam 2
Siv cov khoom ntim zoo ua kom cov ntu no yooj yim dua. Tom qab cov hlau tau rub tawm, nws yuav tsum muaj kev ruaj ntseg. Piv txwv li, cam nws ntxiab mus rau qhov tsis tsim nyog ntawm pawg thawj coj, lossis cua nws ncig lub ntsaws ze tshaj plaws. Qhov no yog qhov tsim nyog thiaj li hais tias yav tom ntej koj tsis txhawj xeeb txog cov xov hlau popping tawm thiab rhuav tshem kev ua haujlwm.
Kauj ruam 3
Preheat soldering hlau kom txog 230 degrees. Ncab cov hlau thiab ua kom sov txhua ceg ntawm microcircuit nyob rau hauv lem. Yog li, txiav tawm ib ntu, unsolder ib feem ntawm microcircuit. Rov ua qhov txheej txheem no nrog lwm tus ib nrab. Thaum muaj ob txhais ceg sab laug rau qhov desoldering, microcircuit tuaj yeem deform, uas tuaj yeem ua kev puas tsuaj nws cov qauv.
Kauj ruam 4
Sim tuav nws nrog koj txhais tes. Tom qab cov txheej txheem tiav lawm, coj cov microcircuit thiab tweezers hauv koj txhais tes thiab ua txhua kab ntawm txhua ceg. Yog tias tsim nyog, siv cov hlau kub uas siv hlau los tshem tawm cov tin uas seem.
Kauj ruam 5
Siv ib rab phom cua kub los tua cov SMD nti. Ua qhov no, tig lub Rooj Tswjhwm Saib thiab muab nws sov. Sim tsis txhob overheat lub cuab yeej thiaj li tsis ua kom puas rau lwm qhov chaw ua haujlwm. Yog li, cov ceg ntawm microcircuit yog rhaub kom txog rau thaum lub sijhawm thaum lawv nyob twj ywm txias txiav tawm siv cov ceg tawv me. Tom qab ntawd, ua kom sov cov hlau soldering thiab ntxuav lub microcircuit los ntawm cov tin seem.
Kauj Ruam 6
Nco ntsoov tias ua ntej koj pib soldering lub microcircuit, nws yuav tsum tau degreased. Txhawm rau ua qhov no, yaug lub rooj tsavxwm hauv kev daws teeb meem. Kev ua haujlwm zoo sib xws yuav tsum tau nqa tawm thaum ua haujlwm nrog hlau cam, yog tias koj kov lub nti nrog koj txhais tes. Qhov no yuav tiv thaiv kev puas tsuaj uas yuav ua tau.
