Technical cov ntsiab lus ntawm hluav taws xob soldering hlau vuam
Soldering lub Cheebtsam ntawm lub Circuit Court board nrog ib tug hluav taws xob soldering hlau yog ib qho yooj yim thiab tsim nyog kev txawj rau hluav taws xob thiab hluav taws xob kws txawj. Ob qho tib si kho thiab sib sau ua ke cov breadboards yuav tsum tau siv phau ntawv soldering txuj ci. Kev paub txog kev vuam hauv kev coj ua tam sim no tau sau tseg rau kev siv los ntawm cov neeg xav tau.
1. Lub hauv paus ntsiab lus ntawm vuam
Lub npe tag nrho ntawm soldering peb siv yuav tsum yog tin brazing, uas yog siv molten solder los khi ob lub hlau tsis-melting ua ke. Lub hauv paus ntsiab lus tseem ceeb yog siv cov molten solder infiltrate lwm qhov chaw hlau ntawm qhov kub thiab txias, kom qhov chaw uas lub solder thiab cov hlau nto yog nyob rau hauv kev sib cuag cov ntaub ntawv ib tug khoom alloy, uas yog welded ua ke nyob rau hauv txias. Rau cov ncauj lus kom ntxaws txog brazing, thov tshawb rau cov ntaub ntawv tseem ceeb hauv online.
2. Cov xwm txheej rau kev vuam zoo
Kev tsim ntawm ib qho kev sib koom ua ke zoo yuav tsum muaj peb yam xwm txheej: qhov chaw huv huv, qhov kub thiab qhov tsim nyog ntawm flux.
Yog tias koj vuam cov khoom qub, cov pins tau oxidized, thiab cov oxide txheej yuav tsum tau ntxuav.
Qhov kub ntawm soldering yuav tsum tsis txhob qis heev. Yog tias qhov ntsuas kub qis, nws yuav cuam tshuam rau qib ntawm cov solder, uas ua rau cov pob qij txha ntxhib, cov duab ntxhib thiab txawm tias burrs. Feem ntau, hluav taws xob soldering irons tsis muaj qhov kub thiab txias ua haujlwm, thiab qhov kub thiab txias yog tswj tsis tau los ntawm kev tswj lub sijhawm soldering, uas yuav tsum muaj qee yam kev paub hauv kev xyaum.
Flux feem ntau siv rosin, tsis txhob siv cov tshuaj txhuam hniav, vim tias cov tshuaj txhuam hniav muaj cov nyhuv corrosive ntawm lub rooj tsavxwm. Siv rosin yuav tsis corrode lub Circuit Court board. Yog tias nws tsis phem dhau, koj tsis tas yuav ntxuav nws tom qab soldering.
3. Kev kho cov hluav taws xob tshiab
Feem ntau siv cov cua sov sab hauv hom hluav taws xob soldering hlau, lub hau ntawm cov hlau tshiab yuav tsum tau tinned ua ntej siv. Lub hom phiaj ntawm tinning yog los txhim kho lub tshav kub conduction ceev ntawm hluav taws xob soldering hlau. Yog hais tias nws tsis yog tinned, lub ntsis ntawm cov hlau soldering yuav oxidized sai li sai tau thaum nws yog rhuab, thiab lub tshav kub hloov efficiency ntawm oxide txheej yog tsawg heev, uas yuav cuam tshuam rau lub vuam nyhuv, thiab txawm yuav ua rau lub phenomenon ntawm cov oxide txheej. soldering ua tsis tau.
Txoj kev ntawm tinning lub soldering hlau:
1. Npaj ib daim ntawm rosin thiab solder hlau.
2. Muab lub hau ntawm cov hlau nplaum tiv thaiv cov rosin, thiab tig rau hluav taws xob kom sov. Raws li qhov kub ntawm cov hlau taub hau nce, rosin yuav yaj. Nyob rau lub sijhawm no, lub taub hau hlau yuav tsum tau txav mus tas li kom lub taub hau ntawm lub taub hau yog qhwv los ntawm cov kua rosin thiab khaws cia los ntawm kev sib cuag nrog huab cua.
3. Thaum qhov kub nce mus txog qhov kub thiab txias ntawm cov hlau solder, siv cov hlau nplaum los txhuam rov qab rau ntawm qhov kawg ntawm cov hlau soldering, kom tag nrho cov hau ntawm cov hlau soldering sib npaug.
4. Fais fab tuag thiab txias. Tom qab lub tinning tiav lawm, nws tuaj yeem siv tau rau yav tom ntej.
