Dab tsi yog cov txiaj ntsig ntawm kev siv rosin rau cov hlau soldering?
Ob peb hnub dhau los, kuv feem ntau pom cov neeg nug tias yog vim li cas rosin yuav tsum tau ntxiv rau solder. Ntawm no kuv roughly summarize nws. Rosin yog feem ntau siv flux, nruab nrab. Yog tias nws yog lub rooj tsav xwm luam tawm tshiab, thov ib txheej ntawm rosin naj hoom rau saum npoo ntawm daim ntawv hlau ua ntej soldering. Yog hais tias nws yog ib lub rooj tsav xwm Circuit Court uas twb tau ua lawm, nws tuaj yeem ncaj qha soldered. Qhov tseeb, kev siv rosin nyob ntawm tus kheej tus cwj pwm. Qee tus neeg yuav poob qhov ntxeev ntawm cov hlau soldering hauv rosin tom qab soldering ib feem. Kev siv cov rosin kuj yog ib qho yooj yim heev, tsuas yog qhib lub thawv rosin thiab dip lub taub hau ntawm lub zog hluav taws xob rau ntawm nws. Yog tias cov tub ntxhais siv tau siv rau vuam, nws yog ib qho tsim nyog yuav tau ntxiv qee cov rosin; Yog tias siv rosin solder hlau, rosin tuaj yeem raug tshem tawm.
Lub luag hauj lwm ntawm rosin nyob rau hauv soldering. Rosin yuav tsis muaj zog acidity ntawm qhov kub thiab txias ntawm cov hluav taws xob soldering hlau, uas tuaj yeem ntxuav cov oxide txheej ntawm qhov chaw soldering, yog li ntawd lub solder tuaj yeem nkag mus rau hauv qhov chaw soldering. Niaj hnub no, yuav muaj rosin nyob rau hauv nruab nrab ntawm cov solder siv nyob rau hauv kev lag luam electronics. Tsuas yog dipped ib co ntawm cov hluav taws xob soldering hlau, thiab cov hlau solder yuav ncaj qha mus rau hluav taws xob soldering hlau ua hauj lwm. Cov hom flux tuaj yeem kwv yees faib ua peb ntu: organic, inorganic thiab cob. Resin flux feem ntau yog muab rho tawm los ntawm cov ntoo, uas yog cov khoom ntuj tsim thiab tsis corrosive. 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 muag muag muag thiab cov tawv tawv tawv sib xws rau cov khoom siv. Mos fluxes 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 raug xaiv raws li qhov sib txawv vuam workpieces hauv ntau zaus. Thaum siv flux, nws yuav tsum tau siv rau hauv qhov tsim nyog raws li qhov loj me thiab qhov chaw ntawm lub workpiece yuav tsum tau welded. 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 lub Cheebtsam los yog deteriorate lub rwb thaiv tsev kev ua tau zoo ntawm lub Circuit Court board.
