Ua rau thiab kev daws teeb meem yog vim li cas cov hlau soldering tsis lo rau Tin
Thaum siv hluav taws xob soldering hlau rau kev ua haujlwm vuam, nws feem ntau pom tias cov hlau nplaum tsis lo rau tin. Yog hais tias lub taub hau ntawm cov hlau tsis lo rau cov tin, kev ua haujlwm tsis tuaj yeem ua. Kev hloov ntau zaus ntawm cov taub hau hlau kuj yog ib qho kev siv nyiaj loj yog tias nws tsis siv kom raug. Nyob rau hauv cov ntaub ntawv no, ntxiv rau cov teeb meem zoo ntawm lub soldering hlau taub nws tus kheej, hauv qab no kuv yuav muab ib tug ncauj lus kom ntxaws piav qhia ntawm lub laj thawj yog vim li cas lub soldering hlau taub tsis lo rau tin thiab yuav ua li cas kho nws:
■ Yog vim li cas vim li cas lub taub hau hlau tsis lo rau tin
1. Feem ntau cov lus qhia ntawm cov hlau yog ua los ntawm tooj liab. Copper reacts nrog oxygen nyob rau hauv cov huab cua ntawm qhov kub thiab txias los tsim dub tooj liab oxide (CuO), thiab tooj liab oxide tsis lo rau tin.
2. Yog tias qhov kub thiab txias dhau lawm, cov tin uas txuas rau saum npoo ntawm lub taub hau ntawm lub taub hau yuav yaj sai sai thiab volatilize, ua rau muaj zog oxidation. Kub kub yuav tsum tau ntau tin.
3. Siv cov kev tu tsis raug lossis tsis raug.
4. Siv cov tshuaj tsis huv los yog cov flux nyob rau hauv cov hlau soldering raug cuam tshuam.
5. Kev ua haujlwm kub siab tshaj 350 degree, thiab vuam yog nres rau ntau tshaj 1 teev, thiab tus nqi ntawm cov tin ntawm lub taub hau hlau yog me heev.
6. "Kev kub hnyiab" ntawm lub taub hau hlau, piv txwv li: qhov chaw nres tsheb soldering yog qhib thiab tsis siv, tab sis qhov saum npoo ntawm lub taub hau hlau tsis yog tinned.
7. Cov flux siv yog corrosive heev, ua rau oxidation ceev ntawm cov hlau taub hau.
8. Cov oxide ntawm lub taub hau hlau tsis tu ncua tsis tu ncua.
■ Yuav ua li cas nrog soldering hlau taub tsis muaj tin sticking
1. Ua los ntawm oxidation nto. Ua ntej, ua kom sov cov hlau nplaum thiab txhuam nws ntau zaus hauv rosin kom tshem tawm cov nplai oxide, thiab tom qab ntawd poob rau hauv solder.
2. Yuav ua li cas "hlawv" lub taub hau hlau: siv hluav taws xob los ua kom sov cov hlau nplaum kom sov li qub, tom qab ntawd siv cov ntaub ntawv los yog cov ntawv xuab zeb tshem tawm cov dub tooj liab oxide nyob rau saum npoo ntawm cov hlau soldering, ces tam sim ntawd poob rau hauv rosin. , thiab ces dai lub tin.
3. Nws raug nquahu kom siv ib daim txhuam cev ntxuav thiab lub tshuab ntxhua khaub ncaws.
4. lav qhov zoo ntawm tin
5. Nws raug nquahu kom ntxiv tin rau kev tiv thaiv thaum tsis siv.
6. Nws yuav ua rau oxidation ceev ntawm cov hlau taub hau.
7. Xaiv cov dej ntws zoo. Nws raug nquahu kom siv nruab nrab active flux.
8. Ntxuav lub taub hau ntau dua
Lub txheej txheej ntawm cov hlau nplaum yog npog nrog cov txheej hlau uas muaj kev sib raug zoo nrog cov hlau yaj, uas yog lub npe hu ua lub neej ntev-lub neej soldering hlau taub. Yog li ntawd, koj yuav tsum tsis txhob siv cov cuab yeej xws li cov ntaub ntawv tshem tawm cov oxide txheej. Yog hais tias koj ua ntaub ntawv tawm ntawm txheej txheej ntawm hlau, , soldering hlau taub yuav tsis raug stained nrog solder thiab yuav tsum scrapped. Nws tsuas tuaj yeem hloov nrog ib qho tshiab ua ntej nws tuaj yeem siv txuas ntxiv mus.
Lub soldering hlau yuav tsum tau muab tso rau ntawm lub soldering hlau sawv ntsug nrog lub taub hau ntawm lub taub hau taub hau kom lub cua sov yuav tsis muaj concentrated nyob rau hauv lub taub hau soldering hlau, yog li ncua lub neej kev pab cuam ntawm soldering hlau taub hau.
Lub rectifier diode thiab ib qho kev hloov pauv tau txuas nrog nyob rau hauv tib lub sijhawm thiab nyob rau hauv series mus rau lub hwj chim qaum ntawm cov hluav taws xob soldering hlau los ua ib qho khoom siv uas tig tawm qhov hloov thaum lub sijhawm ua haujlwm. Qhov no yuav tsis ua rau cov hlau ua kom txias, tab sis tuaj yeem ua kom lub taub hau ntawm lub taub hau nyob rau hauv lub tshav kub preservation, tig lub hloov rau thaum soldering dua, ces cov hlau soldering tuaj yeem ua hauj lwm ib txwm, xyuas kom meej tias cov hlau tsis zoo. hlawv tawm.
