Taw qhia rau cov laj thawj thiab kev daws teeb meem rau soldering hlau taub tsis quav rau tin
Thaum tsis muaj dab tsi soldering, tej zaum yuav muaj qhov tshwm sim uas sharing hlau taub tsis lo rau tin. Ntxiv rau cov teeb meem zoo ntawm soldering Hlau taub hau, peb kuj tseem tuaj yeem nrhiav cov laj thawj ntawm cov xwm txheej no los ntawm cuaj lwm yam:
1. Xaiv qhov kub thiab txias uas yog dhau lawm tuaj yeem yooj yim ua rau oxidation hnyav ntawm solding hlau ntxeev ntawm lub tin nto.
2. Tsis txhob noj cov tin ntawm lub tin coated nto ua ntej siv.
3. Siv cov qauv kev ntxuav tsis raug.
4. Cuam tshuam ntawm flux hauv impure solder lossis vuam hlau.
5. Thaum kev ua haujlwm kub tshaj 350 degree thiab surning nres rau ntau tshaj 1 teev, tus nqi ntawm cov soldering soldering cam cov lus qhia yog tsawg heev.
6. Qhuav hlawv "hluav taws xob soldering hlau cov lus qhia, thiab cov hluav taws xob soldering hlau, tuaj yeem ua rau cov hluav taws xob nrawm ntawm cov hluav taws xob soldering hlau taub.
7. Lub flux siv yog corrosive heev, ua rau muaj oxidation sai ntawm soldering hlau taub;
8. Siv nruab nrab thiab nquag soldering flux, tsis muaj ntau zaus ntxuav cov oxide ntawm cov taub hlau soldering
9. Tiv tauj nrog cov tshuaj organic xws li plastics, roj nplua nyeem, lossis lwm qhov sib txuas. Txoj kev tuav ib txwm:
Nws yog kom siv rab riam me me los txhuam ntawm Oxide txheej ntawm soldering hlau tswv yim uas tsis tau oxidized los ntawm huab cua. Tom qab ntawd, muab tso rau hauv ib lub thawv rosin thiab ntsawj nws hauv, tom qab ntawd hle nws hauv tin, thiab nws tuaj yeem siv tau ib txwm muaj. Txawm li cas los xij, txoj kev no tsis meej huv si, thiab lub sijhawm hloov mus ntev, cuam tshuam rau qhov kub thiab txias, thiab txawm tias ua rau cov taub hlau cam.
Cov txheej txheem nrawm thiab ua tau zoo yog:
Tuav tus ntoo tuav ntawm cov hluav taws xob soldering hlau, tiv thaiv cov oxidized soldering cam rau hauv lub thawv ntim dej cawv. Tom qab 1-2 feeb, tshem tawm cov oxide kiag li thiab huv si, thiab solding hlau taub yuav ua kom rov zoo. Qhov no yog vim tias tom qab cov tooj cua cua kub oxide thiab dej cawv, ib qho tshuaj tiv thaiv kev siv hluav taws xob, uas txo tus tooj liab thiab tsis muaj kev cuam tshuam rau cov cam taub hlau cam.
