Yog vim li cas thiab kev daws teeb meem rau tsis tin sticking ntawm hluav taws xob soldering hlau tswv yim
Thaum lub sij hawm cov txheej txheem vuam tsis muaj hlau lead, tej zaum yuav muaj qhov xwm txheej uas cov hluav taws xob soldering hlau taub tsis lo rau tin. Ntxiv nrog rau qhov teeb meem zoo ntawm hluav taws xob soldering hlau taub hau nws tus kheej, peb kuj tuaj yeem txheeb xyuas cov laj thawj rau cov xwm txheej zoo li no los ntawm cuaj lwm yam:
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. Kev cuam tshuam ntawm flux hauv kev siv cov khoom siv tsis huv lossis cov hlau tsis huv.
5. Thaum ua haujlwm kub siab tshaj 350 degree thiab welding 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. Qhuav kub "hluav taws xob soldering hlau taub, xws li thaum lub rooj soldering yog qhib thiab tsis siv, thiab qhov saum npoo ntawm soldering hlau taub yog tsis muaj tin, tuaj yeem ua rau oxidation sai ntawm cov hlau soldering.
7. Cov flux siv yog corrosive heev, ua rau oxidation sai ntawm cov hlau taub hau;
8. Siv nruab nrab active flux tsis tu ncua tu cov oxide ntawm lub taub hau hlau soldering
9. Sib cuag nrog cov khoom siv organic xws li cov yas, cov roj nplaum, lossis lwm cov khoom sib txuas. Ib txwm tuav txoj kev:
Nws yog siv rab riam me me los txhuam ntawm Oxide txheej ntawm cov hluav taws xob soldering hlau taub hau, ua rau tooj liab uas tsis tau oxidized los ntawm huab cua. Tom qab ntawd, poob rau hauv ib lub thawv rosin thiab poob rau hauv tin, thiab koj tuaj yeem siv nws ib txwm. Txawm li cas los xij, txoj kev no tsis zoo rau kev tu, thiab yog tias khawb rau lub sijhawm ntev, lub hau ntawm cov hlau nplaum yuav ua rau nyias nyias thiab cuam tshuam rau kev hloov mus rau cov cua sov, ua rau qhov kub thiab txias thiab txawm tias puas tsuaj rau cov hlau taub hau.
Txoj kev ceev thiab ua tau zoo yog:
Tuav tus ntoo kov ntawm cov hluav taws xob soldering hlau, raus lub oxidized soldering hlau taub rau hauv lub thawv uas muaj cawv. Tom qab 1-2 feeb ntawm kev tshem tawm, cov oxide raug tshem tawm tag nrho thiab huv si, thiab cov taub hau hlau zoo li tshiab kiag li. Qhov no yog vim hais tias tom qab cua sov tooj liab oxide thiab cawv, muaj tshuaj lom neeg cov tshuaj tiv thaiv tshwm sim, uas nyob rau hauv lem yuav txo tau tooj liab thiab tsis muaj corrosive nyhuv ntawm hluav taws xob soldering hlau taub hau.
