Cov txiaj ntsig ntawm kev siv rosin hauv hluav taws xob soldering hlau
Nyob rau hauv cov hnub tsis ntev los no, kuv feem ntau pom cov neeg nug yog vim li cas rosin yuav tsum tau ntxiv rau soldering tin. Ntawm no, kuv tau roughly summarized nws. Rosin yog feem ntau siv flux, nruab nrab. 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 hais tias lub Circuit Court board twb ua, nws tuaj yeem ncaj qha soldered. Qhov tseeb, kev siv rosin nyob ntawm tus kheej tus cwj pwm. Qee tus neeg muab lub taub hau ntawm lub taub hau ntawm lub rosin txhua zaus lawv txuas cov khoom. 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 tias siv rosin tin vuam hlau, rosin yuav tsis siv.
Lub luag hauj lwm ua si los ntawm rosin nyob rau hauv soldering. Rosin yuav tsis muaj zog acidity ntawm qhov kub ntawm cov hluav taws xob soldering hlau, uas tuaj yeem ntxuav cov oxide txheej ntawm qhov chaw vuam thiab tso cai rau cov hlau los so hauv qhov chaw vuam. Niaj hnub no, feem ntau yog rosin nyob rau hauv nruab nrab ntawm soldering tin siv nyob rau hauv lub electronics kev lag luam. Tsuav muaj me ntsis ntawm nws ntawm cov hlau soldering, cov hlau soldering tuaj yeem ua haujlwm ncaj qha rau ntawm cov hlau soldering. Cov hom flux feem ntau tuaj yeem muab faib ua peb qhov loj: organic, inorganic, thiab cob. Resin flux feem ntau yog muab rho tawm los ntawm kev zais ntawm cov ntoo, uas yog cov khoom ntuj tsim thiab tsis muaj corrosivity. Rosin yog tus sawv cev ntawm hom flux, yog li nws tseem hu ua rosin flux. Vim hais tias flux feem ntau yog siv ua ke nrog solder, nws tuaj yeem muab faib ua cov flux mos thiab tawv flux sib haum rau cov khoom siv. Cov khoom muag muag muag xws li rosin, rosin mix flux, solder paste, thiab hydrochloric acid feem ntau yog siv los ua ke thiab kho cov khoom siv hluav taws xob. Tsis tas li ntawd, lawv yuav tsum tau xaiv raws li qhov sib txawv vuam workpieces nyob rau hauv ntau lub sijhawm. Thaum siv cov flux, nws yuav tsum tau ua kom zoo raws li qhov loj me thiab qhov chaw ntawm qhov vuam. Yog tias qhov nyiaj tsawg dhau, qhov vuam zoo yuav raug cuam tshuam. Yog tias tus nqi ntau dhau lawm, cov khoom seem flux yuav corrode cov khoom los yog ua rau lub rwb thaiv tsev kev ua tau zoo ntawm lub rooj tsav xwm Circuit Court tsis zoo.
