Ntau tus phooj ywg ntawm yoj soldering muaj tin-txuas cov xwm txheej thaum siv yoj soldering, uas yog teeb meem heev.Cov laj thawj tseem ceeb rau qhov xwm txheej no yog cov hauv qab no:
Flux kev ua si tsis txaus.
Flux tsis ntub txaus.
Tus nqi ntawm cov flux siv tsawg dhau.
Daim ntawv thov flux tsis sib xws.
Lub cheeb tsam Circuit Court board tsis tuaj yeem coated nrog flux.
Tsis muaj tin nyob rau hauv Circuit Court board.
Qee cov ntaub qhwv los yog cov ko taw yog oxidized hnyav heev.
Cov kab hluav taws xob thaiv hluav taws xob tsis tsim nyog (tsis tsim nyog faib cov khoom sib txuas).
Txoj kev taug kev tsis yog lawm.
Cov ntsiab lus tin tsis txaus, lossis cov tooj liab tshaj tus qauv;[ntau impurities ua rau lub melting point (liquidus) ntawm cov kua tin nce] lub foaming raj yog thaiv, thiab cov foaming tsis sib xws, uas ua rau cov txheej tsis sib xws ntawm flux ntawm lub rooj tsavxwm Circuit Court.
Kev teeb tsa cua riam tsis tsim nyog (flux tsis tshuab sib npaug).
Lub rooj tsavxwm ceev thiab preheating tsis zoo sib xws.
Txoj kev ua haujlwm tsis raug thaum dipping tin los ntawm tes.
Lub inclination ntawm cov saw yog tsis tsim nyog.
Lub crest yog uneven.
Txij li thaum txuas lub tin yuav ua rau luv luv Circuit Court ntawm pcb, nws yuav tsum tau kho ua ntej nws yuav siv tau.Txoj kev kho yog taw tes me ntsis flux (uas yog, rosin roj hnyav), thiab tom qab ntawd siv qhov kub thiab txias ferrochrome los ua kom sov txoj hauj lwm ntawm cov khoom sib txuas kom yaj nws, thiab txoj hauj lwm ntawm qhov sib txuas tin nyob rau hauv qhov kev txiav txim ntawm qhov nro. , nws yuav thim rov qab thiab tsis luv luv Circuit Court.
Kev daws teeb meem
1. Lub flux tsis txaus los yog tsis zoo txaus, ua kom cov ntws.
2. Lianxi ceev ceev thiab ua kom lub kaum sab xis khiav.
3. Tsis txhob siv 1 nthwv dej, siv 2 nthwv dej ntawm ib nthwv dej, qhov siab ntawm lub tin tsis tas yuav tsum yog 1/2, nws yog txaus los kov lub hauv qab ntawm lub rooj tsavxwm.Yog tias koj muaj lub tais, sab tin yuav tsum nyob rau sab siab tshaj ntawm lub tais hollow.
4. Puas yog lub rooj tsavxwm deformed?
5. Yog tias 2-yoj ib zaug txhaj tshuaj tsis zoo, siv 1 nthwv dej rau xuas nrig ntaus, thiab 2-yoj hits qis txaus los kov tus pin, kom cov duab ntawm cov hlua khi tuaj yeem kho, thiab nws yuav zoo thaum nws tawm los.
Rau cov laj thawj saum toj no, koj tuaj yeem tshawb xyuas seb lub tshuab yoj yoj soldering puas muaj teeb meem hauv qab no:
1. Peak qhov siab nrug.
2. Seb cov saw ceev yog tsim nyog.
3. Kub.
4. Seb tus nqi ntawm cov tin nyob rau hauv lub cub tawg puas txaus.
5. Puas yog yoj crest tawm ntawm lub tin txawm?
