Yuav ua li cas pab tau rosin rau soldering hlau?
Rosin yog feem ntau siv flux. Nws yog nruab nrab thiab yuav tsis corrode Circuit Court Cheebtsam thiab soldering hlau tswv yim. Qhov no tso cai rau cov tin droplets sai sai lo rau lub rooj tsavxwm Circuit Court thaum vuam, thiab tus so tsuas yog tos cov tin droplets kom txias. Nyob rau hauv txoj kev no, qhov zoo ntawm cov khoom welded yog guaranteed.
Ua ntej tshaj plaws, thaum cov tin droplets nyob rau hauv lub xeev cov kua, cov pob qij txha solder yog heev puv, vim hais tias cov fluidity ntawm cov kua tin droplets tsis zoo heev thiab yeej yuav nyob ib sab ntawm cov hluav taws xob pins. Thaum nws solidifies, nws yuav tsis hloov ntau.
Kev ua haujlwm ntawm rosin kuj suav nrog tshem tawm cov oxides ntawm cov hlau saum npoo thiab pab qhov sib txawv ntawm cov tin.
Nyob rau hauv cov nqe lus ntawm cov pob qij txha, nws tuaj yeem txuas cov khoom tsis muaj kev txhawb nqa; ua kom sov dissipation; thiab ua hluav taws xob. Yog li ntawd, los ntawm cov yam ntxwv no, rosin muaj txiaj ntsig zoo rau cov kev xav tau ntawm vuam.
Lub luag haujlwm tseem ceeb yog los pab cov soldering. Cov kev siv yog: 1. Dip lub kub soldering hlau rau hauv solder. 2. Dip lub kub soldering hlau rau hauv rosin. 3. Siv cov hlau soldering nrog rosin thiab solder rau solder.
Qhov txiaj ntsig loj tshaj plaws ntawm rosin yog: tin cov xov hlau, vim nws nyuaj rau tin cov xov hlau tsis muaj rosin. Ua ntej sov cov hlau soldering, ces muab cov hlau soldering nyob rau hauv lub rosin, tshem tawm cov hlau soldering, dipped nyob rau hauv tin, thiab ces muab tso rau hauv rosin, thiab ces muab cov xov hlau rau tinned nyob rau hauv, thiaj li hais tias tinning yog yooj yim dua. Lwm txoj haujlwm yog muab cov hlau uas tau muag tshiab rau hauv cov rosin, thiab tom qab ntawd siv cov tin. Tag nrho lub taub hau soldering hlau yuav npog nrog tin. Tom qab siv cov hlau soldering yav tom ntej, nws yuav tau ntim nrog tin. Lwm zaus koj siv cov hlau soldering, nws yuav tsis tau ntim nrog tin. Lub taub hau hlau yog oxidized thiab ua tsis tau.
Rosin ua raws li cov flux hauv vuam.
Kev hais lus theoretical, lub melting point ntawm flux yog qis dua li ntawm solder, thiab nws qhov tshwj xeeb lub ntiajteb txawj nqus, viscosity, thiab nto nro yog me dua li ntawm solder. Yog li ntawd, thaum lub sij hawm vuam, cov flux melts ua ntej, ces sai sai ntws thiab npog cov saum npoo ntawm lub solder, cais cov huab cua thiab tiv thaiv cov hlau nto los ntawm nws muaj cov nyhuv ntawm oxidation thiab muaj peev xwm hnov mob nrog oxide zaj duab xis ntawm solder thiab hlau. raug welded nyob rau hauv qhov kub ntawm welding, ua rau nws yaj thiab restore lub ntshiab hlau nto. Qhov tsim nyog solder pab tsim kom muaj kev sib koom ua ke zoo thiab ua kom lub ntsej muag gloss ntawm cov pob qij txha.
Yog tias nws yog lub rooj tsav xwm luam tawm tshiab, thov ib txheej ntawm dej rosin rau saum npoo ntawm daim ntawv tooj liab ua ntej soldering. Yog hais tias lub Circuit Court board twb ua lawm, nws tuaj yeem raug soldered ncaj qha. Qhov tseeb, kev siv rosin nyob ntawm tus kheej tus cwj pwm. Qee tus neeg yuav dipped cov hlau taub hau hauv rosin tom qab soldering ib feem. Kuv ib txwm ua nws thaum lub taub hau hlau yog oxidized thiab tsis yooj yim siv. Soak ib co rosin nyob rau hauv nws. Kev siv rosin kuj yooj yim heev. Tsuas yog qhib lub thawv rosin thiab poob lub zog siv hluav taws xob hlau taub hauv nws.
Yog tias cov tub ntxhais siv cov khoom siv tau siv thaum lub sijhawm vuam, ntxiv qee cov rosin yog tsim nyog; Yog hais tias rosin tin soldering hlau yog siv (cov tub ntxhais ntawm cov hlau soldering yog qhwv nrog flux), rosin tsis tas yuav tsum tau.
Txij li cov hlau saum npoo yuav tsim cov oxide zaj duab xis thaum nws los rau hauv kev sib cuag nrog huab cua, qhov kub thiab txias, qhov hnyav dua qhov oxidation yuav ua tau. Cov yeeb yaj kiab oxide no tiv thaiv cov kua nplaum los ntawm cov hlau ntub dej, ib yam li cov roj ntawm iav tiv thaiv dej los ntawm ntub nws. Flux yog ib yam khoom tshwj xeeb uas siv los tshem tawm cov yeeb yaj kiab oxide, tseem hu ua flux. Flux muaj peb lub luag haujlwm tseem ceeb: 1. Tshem tawm oxide zaj duab xis. Lub essence yog hais tias cov tshuaj nyob rau hauv lub flux undergo ib tug txo cov tshuaj tiv thaiv, yog li tshem tawm cov oxide zaj duab xis, thiab cov tshuaj tiv thaiv cov khoom yuav raug tshem tawm slag, ntab rau saum npoo ntawm solder. 2. Tiv thaiv oxidation. Tom qab nws melts, nws ntab rau saum npoo ntawm lub solder los tsim ib txheej cais, yog li tiv thaiv oxidation ntawm soldering nto. 3. Txo qhov nro ntawm qhov chaw, ua kom cov kua dej ntau ntxiv, thiab pab kom ntub cov welding.
