Yog vim li cas siv rosin nrog ib tug hluav taws xob soldering hlau, yuav ua li cas xaiv ib tug, thiab yuav ua li cas xaiv ib tug
Kev xaiv cov khoom siv hluav taws xob tsim nyog yuav pab txhim kho kev ua tau zoo ntawm peb cov hlau nplaum hauv cov khoom siv hluav taws xob tsis muaj cov hlau lead, tab sis feem ntau, kev xaiv yuav tsum yog raws li qhov tseeb ntawm cov khoom yuav tsum tau welded, thiab feem ntau tsom rau daim ntawv cua sov. , lub zog loj, thiab lub taub hau hlau. zoo li lwm yam.
Raws li kev xaiv ntawm hluav taws xob soldering hlau cua sov daim ntawv
1. Kev xaiv ntawm cov cua sov sab hauv thiab cov cua sov sab nraud: Nyob rau hauv tib lub wattage, qhov kub ntawm cov cua sov sab hauv soldering hlau yog siab dua li ntawm cov cua sov sab nraud soldering hlau.
2. Thaum qhov kub thiab txias yuav tsum tau soldering, siv ib tug voltage regulator los tswj qhov kub ntawm hluav taws xob soldering hlau. Qhov kub ntawm hluav taws xob soldering hlau yog ze ze rau lub hwj chim mov voltage. Hauv kev siv tiag tiag, qhov kub ntawm cov hluav taws xob soldering hlau feem ntau txo qis los ntawm kev txo cov hluav taws xob hluav taws xob.
3. Tswj qhov kub thiab txias los ntawm kev kho qhov ntev ntawm lub taub hau soldering.
4. Muaj ntau txoj hauv kev hauv qab no txhawm rau txhim kho qhov kub thiab txias ntawm cov hluav taws xob soldering hlau: nruab ib lub zog ruaj khov los tiv thaiv kev hloov pauv hauv cov khoom siv hluav taws xob; tuav ib qho ntim, qhov ntev thiab cov duab ntawm lub taub hau hlau soldering; siv lub ntsuas kub tsis tu ncua hluav taws xob soldering hlau; ua kom qhov kub nyob hauv tsev tsis tu ncua; tsis txhob ntuj cua lossis hluav taws xob kiv cua thiab lwm yam.
Raws li kev xaiv ntawm soldering hlau fais fab
1. Thaum soldering tsis kam-capacitance Cheebtsam nrog me me wattage, transistors, integrated circuits, pads ntawm luam Circuit Court boards los yog yas nyob ntawm tej, nws yog advisable siv ib tug 30 ~ 45W sab nraud cua sov hom los yog ib tug 20W internal cua sov hom hluav taws xob soldering hlau. Nws yog qhov zoo tshaj plaws los siv 20W sab hauv cua sov hom hluav taws xob soldering hlau hauv daim ntawv thov.
2. Thaum vuam cov ntsiab lus ntawm cov khoom siv dav dav, xws li cov hlua hlau, hlau claws, cov dab dej kub, cov khoom siv hauv av, thiab lwm yam, nws raug nquahu kom siv 75 ~ 100W hluav taws xob soldering hlau.
3. Rau cov pob qij txha loj, xws li vuam hlau rack tabs, solder tabs, thiab lwm yam, nws raug nquahu kom siv 100 ~ 200W hluav taws xob soldering hlau.
Vim li cas hluav taws xob soldering hlau siv rosin
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 tooj liab 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 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 ib co 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 uas sib haum rau cov solder. 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.
