Qhov kev daws teeb meem rau cov hlau taub hau tsis lo rau tin
1. Yog hais tias qhov kub thiab txias heev, nws yog ib qho yooj yim uas yuav ua rau oxidation hnyav nyob rau hauv tin nto ntawm lub soldering hlau taub.
2. Tsis txhob noj tinned nto ua ntej siv.
3. Siv cov kev tu tsis raug lossis tsis raug.
4. Kev siv cov khoom siv tsis huv lossis kev cuam tshuam ntawm flux hauv cov hlau.
5. Thaum ua hauj lwm kub siab tshaj 350 degree thiab lub soldering yog nres rau ntau tshaj 1 teev, tus nqi ntawm cov tin ntawm cov hlau lead-free soldering ntsis yog tsawg heev.
6. "Kev kub kub" hluav taws xob soldering hlau taub, xws li: qhov chaw nres tsheb soldering tsis siv, thiab tsis muaj tin nyob rau saum npoo ntawm hluav taws xob soldering hlau taub, uas yuav ua rau oxidation sai ntawm cov hluav taws xob soldering hlau taub.
7. Cov flux siv yog corrosive heev, uas ua rau oxidation ceev ntawm lub soldering hlau taub;
8. Siv nruab nrab active flux, thiab tsis txhob nquag ntxuav cov oxides ntawm qhov kawg ntawm cov hlau soldering.
9. Sib cuag nrog cov khoom siv organic xws li cov yas, cov roj lubricating lossis lwm cov khoom sib txuas. Txoj kev coj noj coj ua:
Nws yog siv rab riam los txhuam cov oxide txheej ntawm cov hlau nplaum kom nthuav tawm cov tooj liab uas tsis tau oxidized los ntawm huab cua. Tom qab ntawd, muab tso rau hauv lub thawv rosin thiab dip nws, ces muab tso rau hauv tin, thiab nws tuaj yeem siv tau ib txwm. Txawm li cas los xij, txoj kev no tsis tshem nws kom huv si. Nyob rau tib lub sijhawm, yog tias nws tau muab pov tseg rau lub sijhawm ntev, lub hau ntawm cov hlau soldering yuav thinner thiab cuam tshuam rau kev hloov mus rau cov cua sov, uas ua rau poob rau hauv qhov kub thiab txawm tias puas rau qhov kawg ntawm cov hlau soldering.
Ib txoj hauv kev sai thiab ua tau zoo los ua qhov no yog:
Tuav lub tes tuav ntawm lub tshuab hluav taws xob, muab cov oxidized soldering hlau rau hauv lub thawv ntim nrog cawv, tshem tawm tom qab 1 mus rau 2 feeb, cov oxide yuav raug tshem tawm tag nrho thiab huv si, thiab cov taub hau hlau yuav zoo li tshiab. . Qhov no yog vim hais tias tom qab cov tooj liab oxide thiab cawv yog rhuab, muaj tshuaj lom neeg tshwm sim, thiab cov tooj liab raug txo, uas tsis muaj corrosion cuam tshuam rau lub ntsis ntawm cov hluav taws xob soldering hlau.
