Vim li cas rosin siv hauv hluav taws xob soldering hlau?
Rosin yog feem ntau siv solder, uas yog nruab nrab thiab tsis corrode Circuit Court Cheebtsam thiab soldering hlau tswv yim. Nws tuaj yeem tso cai rau cov tin tee kom nrawm nrawm rau lub rooj sib tham hauv Circuit Court thaum lub sij hawm soldering, thiab tus so tuaj yeem zaum thiab tos cov tin droplets kom txias, kom ntseeg tau tias qhov zoo ntawm cov khoom soldered.
Ua ntej, nyob rau hauv cov ntaub ntawv ntawm ib tug kua tin droplet, lub solder sib koom ua ke yog tag nrho vim hais tias cov fluidity ntawm cov kua tin droplet tsis zoo heev, thiab nws feem ntau nyob ntawm ib sab ntawm cov hluav taws xob ko taw. Thaum nws solidifies, yuav tsis muaj kev hloov tseem ceeb.
Kev ua haujlwm ntawm rosin kuj suav nrog lub peev xwm tshem tawm oxides ntawm cov hlau nto thiab pab hauv kev nthuav dav ntawm tin.
Nyob rau hauv cov nqe lus ntawm cov pob qij txha, lawv tuaj yeem ua cov khoom sib txuas yam tsis muaj kev txhawb nqa tshuab; Coordinate tshav kub dissipation; Thiab cov nyhuv conduction ntawm hluav taws xob, yog li los ntawm cov yam ntxwv no, rosin muaj txiaj ntsig zoo rau cov kev cai vuam zoo tib yam.
Lub luag haujlwm tseem ceeb yog los pab vuam, thiab kev siv yog: 1. Dip ib lub kub soldering hlau hauv soldering tin. 2. Dip ib tug kub soldering hlau nyob rau hauv rosin. 3. Weld nrog ib tug soldering hlau uas muaj rosin thiab soldering tin
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 lub hluav taws xob soldering hlau, ces muab tso rau hauv lub rosin, tshem tawm cov hluav taws xob soldering hlau, dipped nyob rau hauv tin, thiab ces muab tso rau hauv lub rosin. Tom qab ntawd, muab cov hlua khi rau hauv tinned, ua kom yooj yim dua rau tin. Lwm txoj haujlwm yog muab cov khoom siv hluav taws xob uas tau muag tshiab rau hauv rosin, tom qab ntawd tin nws, thiab sau tag nrho cov hlau taub hau nrog cov tin. Tom qab siv cov hlau soldering, nws yuav tsum tau ntim nrog tin. Lwm zaus koj siv cov hlau soldering, nws yuav tsis yooj yim rau siv vim oxidation ntawm lub taub hau soldering hlau.
Rosin ua hauj lwm raws li ib tug soldering flux nyob rau hauv vuam, ua si lub luag hauj lwm soldering.
Nyob rau hauv txoj kev xav, lub melting point ntawm flux yog qis dua li ntawm cov solder, thiab nws qhov tshwj xeeb lub ntiajteb txawj nqus, viscosity, thiab nto nro yog tag nrho qis dua li ntawm solder. Yog li ntawd, thaum lub sij hawm welding, lub flux melts ua ntej, sai sai ntws thiab npog qhov chaw ntawm lub solder, cais huab cua thiab tiv thaiv hlau nto oxidation. Nws tuaj yeem ua rau lub ntsej muag oxide zaj duab xis ntawm solder thiab cov hlau soldered ntawm qhov kub thiab txias thaum lub sij hawm vuam, ua rau nws yaj thiab rov ua cov hlau ntshiab. Kev sib txuas kom zoo yuav pab tsim cov duab zoo sib xws thiab ua kom lub ntsej muag gloss ntawm cov pob qij txha.
Yog tias nws yog ib lub rooj tsav xwm luam tawm tshiab, ib txheej ntawm cov tshuaj tsw qab xoob yuav tsum tau coated rau ntawm cov ntawv ci tooj liab ua ntej vuam. Yog tias nws yog lub rooj tsav xwm ua ntej ua ntej, nws tuaj yeem ncaj qha soldered. Qhov tseeb, kev siv rosin nyob ntawm tus kheej tus cwj pwm. Qee tus neeg yuav tsau lub taub hau ntawm cov rosin tom qab vuam txhua feem; Kuv ib txwm tsau ib co rosin ntawm lub ntsis ntawm cov hlau soldering thaum nws yog oxidized thiab tsis yooj yim rau siv. Kev siv rosin kuj yooj yim heev. Qhib lub rosin lub thawv thiab tsau lub hwj chim soldering hlau taub rau nws.
Yog tias cov khoom siv tau siv thaum lub sijhawm vuam, yuav tsum tau ntxiv qee cov rosin; Yog hais tias rosin tin solder hlau yog siv (nrog flux qhwv hauv cov tub ntxhais hlau), rosin tuaj yeem raug tshem tawm.
Vim yog qhov tsim ntawm oxide zaj duab xis ntawm cov hlau nto tom qab kev sib cuag nrog huab cua, qhov kub thiab txias, qhov hnyav dua qhov oxidation. Cov oxide zaj duab xis no tiv thaiv cov nyhuv ntub dej ntawm cov kua nplaum ntawm cov hlau, ib yam li cov roj ntawm iav tiv thaiv dej los ntawm ntub dej. 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 cov oxide zaj duab xis. Lub essence yog 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 ua raug tshem tawm slag, ntab rau saum npoo ntawm solder. 2. Tiv thaiv oxidation. Tom qab melting, nws ntab rau ntawm qhov chaw ntawm lub solder, tsim ib txheej cais, yog li tiv thaiv oxidation ntawm vuam nto. 3. Txo qhov nro ntawm qhov chaw thiab ua kom cov dej ntws tawm tuaj yeem pab cov khoom siv ntub dej.
