Qhov kev daws teeb meem los tiv thaiv cov hlau tsis tau daig hauv tin
Thaum lub sij hawm cov txheej txheem soldering tsis muaj hlau lead, tej zaum yuav muaj ib tug tshwm sim qhov twg cov soldering hlau ntsis tsis ua raws li tin. Ntxiv nrog rau qhov teeb meem zoo ntawm lub taub hau ntawm lub taub hau nws tus kheej, kuj tseem muaj cov laj thawj rau qhov xwm txheej no, xws li xaiv qhov kub thiab txias, uas tuaj yeem ua rau oxidation loj heev ntawm tin nto ntawm lub taub hau hlau, tsis raug. los yog txoj kev tu tsis huv, thiab lwm yam.
Yog vim li cas thiab kev daws rau cov uas tsis yog tin sticking ntawm soldering hlau taub:
Thaum lub sij hawm cov txheej txheem soldering tsis muaj hlau lead, tej zaum yuav muaj ib tug tshwm sim qhov twg cov soldering hlau ntsis tsis ua raws li tin. Ntxiv nrog rau qhov teeb meem zoo ntawm cov hluav taws xob soldering hlau taub hau nws tus kheej, peb kuj tuaj yeem daws cov teeb meem no los ntawm cuaj lwm qhov chaw
Nrhiav rau cov laj thawj ntawm cov ntsiab lus:
1. Xaiv qhov kub thiab txias heev tuaj yeem ua rau oxidation loj heev ntawm cov tin saum npoo ntawm cov hlau taub hau.
2. Tsis txhob noj cov tin ntawm lub tin coated ua ntej siv.
3. Siv cov kev tu tsis raug lossis tsis raug.
4. Siv cov hlau tsis huv los yog cov khoom siv hluav taws xob cuam tshuam rau hauv cov hlau nplaum.
5. Thaum qhov kub thiab txias ua hauj lwm tshaj 350 degree thiab vuam yog nres rau ntau tshaj 1 teev, tus nqi ntawm cov tin ntawm cov hlau lead-free soldering lub taub hau yog tsawg heev.
6. "Kev kub hnyiab" hluav taws xob soldering hlau taub, xws li thaum lub rooj soldering tsis siv thiab tsis muaj tin nyob rau saum npoo ntawm lub taub hau hlau, tuaj yeem ua rau oxidation ceev ntawm cov hlau taub hau.
7. Cov flux siv yog corrosive heev, ua rau oxidation sai ntawm cov hlau taub hau;
8. Siv nruab nrab active flux yam tsis tu ncua tu cov oxide ntawm cov hlau taub hau
9. Sib cuag nrog cov khoom siv organic xws li cov yas, cov roj nplaum, lossis lwm cov khoom sib txuas. Hom kev tuav:
Nws yog siv rab riam me me los txhuam ntawm Oxide txheej ntawm soldering hlau tswv yim, ua rau tooj liab uas tsis tau ua rau huab cua. Tom qab ntawd, muab tso rau hauv ib lub thawv rosin thiab muab tso rau hauv tin, thiab koj tuaj yeem siv nws li niaj zaus. Tab sis txoj kev no tsis meej txaus los tshem tawm, thiab yog tias khawb rau lub sijhawm ntev, lub hau ntawm cov hlau nplaum yuav dhau los ua nyias, cuam tshuam rau kev hloov hluav taws xob, ua rau qhov kub thiab txias, thiab tseem ua rau lub taub hau ntawm cov hlau.
Txoj kev ceev thiab ua tau zoo yog:
Muab cov ntoo kov ntawm lub tshuab hluav taws xob hluav taws xob, muab cov oxidized soldering hlau rau hauv lub thawv uas muaj cawv, thiab tom qab 1-2 feeb, tshem nws. Cov oxide raug tshem tawm tag nrho thiab huv si, thiab cov taub hau hlau zoo li tshiab. Qhov no yog vim hais tias tom qab cua sov nrog tooj liab oxide thiab cawv, tshuaj lom neeg cov tshuaj tiv thaiv tshwm sim, uas txo cov tooj liab thiab tsis muaj corrosive nyhuv ntawm soldering hlau taub.
