Kev siv hluav taws xob soldering hlau thiab cua kub lub tog raj kheej
1. Ua ntej cov hlau soldering tshiab yog energized, tsau rau hauv ntoo thuv tsw.
2. Thaum siv hluav taws xob soldering hlau thawj zaug, dipped ib txheej ntawm tin rau ntawm qhov kawg ntawm cov hlau soldering.
3. Siv rosin los yog tsis-corrosive flux thaum soldering.
4. So lub hau ntawm cov hlau nplaum nrog ib daim txhuam cev ntub dej los yog daim ntaub ntub dej.
5. Tsis txhob siv cov ntawv xuab zeb lossis cov ntaub ntawv los ua kom lub ntsej muag ntawm cov hlau soldering (tshwj tsis yog thaum txiav).
6. Tom qab soldering, tsis txhob so tawm lub solder sab laug ntawm lub ntsis ntawm lub soldering hlau.
7. Lub plhaub ntawm cov hluav taws xob soldering hlau yuav tsum tau muab tso rau hauv av, thiab lub hwj chim yuav tsum raug txiav tawm thaum nws tsis siv sijhawm ntev.
8. Yuav tsum ntxuav cov oxide nyob rau hauv lub plhaub ntawm sab nraud cua sov hluav taws xob soldering hlau los tiv thaiv qhov ntxeev ntawm cov hlau soldering los ntawm kev daig hauv lub plhaub.
Yuav siv cov cua kub lub tog raj kheej li cas kom raug
1) Kho qhov kub thiab txias ntawm lub tog raj kheej cua kub. Xws li: tshuab vuam inline lub rooj yuav tsum muaj qhov kub ntawm 280 thiab 300 degrees. Yog tias nws siab, nws yuav tshuab lub rooj zaum deformed, thiab yog tias nws qis, nws yuav tsis tshuab. Blow-solding soft pob IC yuav tsum muaj qhov kub ntawm 300 thiab 320. Yog tias nws siab dhau lawm, nws yooj yim rau tshuab IC, tab sis yog tias nws qis dhau, nws tsis tuaj yeem tawg, thiab nws yooj yim los rhuav tshem cov ntaub, ua rau irreparable tsis ua hauj lwm.
(2) Kho nws cov cua ceev kom raug. Rau cov neeg pib siv lub rooj cua kub, cov pob qhov rooj ntawm "qhov kub thiab txias" yuav tsum muab tso rau hauv qhov chaw nruab nrab.
(3) Thaum siv, nws yuav tsum nyob rau sab xis ntawm IC thiab 1-2 cm deb ntawm cov khoom kom txav lub tshuab vuam sib npaug, tsis txhob kov cov pins ncaj qha, thiab tsis deb dhau. Tsis txhob tshem tawm IC kom txog thaum IC xoob tag, txwv tsis pub tshem tawm nyuaj yuav ua rau cov ntaub qhwv puas.
(4) Thaum vuam lossis dismantling Cheebtsam, tsis txhob tshuab cua kub tsis tu ncua rau ntau tshaj 20s ntawm ib lub sijhawm, thiab tsis txhob siv cua kub ntau tshaj 3 zaug hauv tib txoj haujlwm.
(5) Thaum ua tiav lossis tsis siv, kho qhov kub thiab txias kom qis tshaj plaws thiab cua ceev kom siab tshaj plaws. Qhov no ua rau nws yooj yim rau dissipate cua sov thiab cua sov sai sai.
