Vim li cas soldering hlau siv rosin?
Kuv feem ntau pom cov neeg nug yog vim li cas rosin ntxiv rau soldering hnub no, thiab ntawm no kuv tau piav qhia txog nws. Rosin yog feem ntau siv soldering 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 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 ntub cov hlau nplaum hauv rosin tom qab soldering txhua feem. Kev siv rosin kuj yooj yim heev. Qhib lub rosin lub thawv thiab tsau cov hluav taws xob 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 tuaj yeem raug tshem tawm.
Lub luag hauj lwm ua si los ntawm rosin thaum lub sij hawm soldering. Rosin muaj cov acidity tsis muaj zog 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 lub vuam kom ntub cov vuam nto. Niaj hnub no, nyob rau hauv kev lag luam electronics, muaj rosin nyob rau hauv nruab nrab ntawm lub solder siv. Tsuas yog poob me ntsis ntawm cov hlau soldering, thiab cov hlau nplaum yuav ua haujlwm ncaj qha rau ntawm cov hlau soldering. Cov hom ntawm soldering flux tuaj yeem faib ua peb pawg: organic, inorganic, thiab resin. Resin flux feem ntau yog muab rho tawm los ntawm cov ntoo ntawm cov ntoo thiab yog cov khoom ntuj tsim nrog me ntsis corrosiveness. Rosin yog tus sawv cev ntawm hom flux, yog li nws tseem hu ua rosin flux. Vim hais tias solder flux feem ntau yog siv ua ke nrog solder, nws muaj peev xwm muab faib ua mos solder flux thiab nyuaj solder flux sib xws rau solder. Feem ntau siv hauv kev sib dhos thiab kev saib xyuas cov khoom siv hluav taws xob muaj xws li rosin, rosin mix flux, solder paste, thiab hydrochloric acid soft flux. Tsis tas li ntawd, kev xaiv yuav tsum yog raws li qhov sib txawv vuam workpieces hauv ntau zaus. Thaum siv solder flux, nws yuav tsum tau siv rau hauv qhov tsim nyog tus nqi raws li qhov loj thiab qhov chaw ntawm qhov chaw welded. Yog tias qhov nyiaj tsawg dhau, nws yuav cuam tshuam rau qhov vuam zoo. Yog tias qhov nyiaj ntau dhau lawm, cov khoom seem ntawm cov khoom siv yuav corrode cov khoom los yog ua rau cov rwb thaiv tsev ua haujlwm ntawm lub rooj tsavxwm.
