Cov lus qhia yooj yim ntawm kev siv cov hlau soldering
Cov hluav taws xob soldering hlau yog cov cuab yeej siv feem ntau hauv kev siv hluav taws xob vuam. Nws txoj haujlwm yog hloov hluav taws xob hluav taws xob rau hauv lub zog hluav taws xob kom sov thiab vuam cov pob qij txha. Ib feem loj ntawm nws txoj kev vam meej nyob ntawm seb nws tswj tau zoo npaum li cas. Yog li ntawd, los ntawm ib qho kev xav, hluav taws xob soldering hlau Kev siv nws yog nyob ntawm kev nkag siab ntawm cov txheej txheem.
Feem ntau hais lus, qhov loj dua lub zog ntawm cov hluav taws xob soldering hlau, qhov kub ntau dua, thiab qhov kub ntawm cov hlau soldering ntau dua. Feem ntau, 20W sab hauv cua sov soldering hlau yog txaus rau vuam transistors thiab integrated circuit electronic Cheebtsam. Lub hwj chim ntau dhau tuaj yeem hlawv cov khoom siv tau yooj yim, vim tias qhov kub thiab txias ntawm diodes thiab transistors yuav hlawv tawm yog tias qhov kub ntawm qhov sib txuas siab tshaj 200 degree. Txawm li cas los xij, nyob rau hauv kev tsim cov raj amplifiers feem ntau yog raws li kev sib tsoo vuam, lub zog ntawm cov hlau soldering yuav tsum siab dua, thiab koj tuaj yeem xaiv ntawm 35W-45W, lossis siab dua.
Nws yog ib nqi sau cia hais tias thaum welding lub Circuit Court, lub sij hawm yuav tsum tsis txhob ntev los yog luv heev. Yog tias lub sijhawm ntev dhau lawm, nws yuav yooj yim puas. Yog hais tias lub sij hawm luv luv, lub solder yuav tsis tag nrho melted, uas ua rau lub solder sib koom ua ke tsis du thiab ruaj, thiab tej zaum kuj tsim ib tug cuav solder. Feem ntau, Lub sijhawm tsim nyog tshaj plaws yuav tsum ua kom tiav hauv 1.5s txog 4s.
Solder yog cov hlau fusible, thiab feem ntau siv ib qho yog solder hlau. Lub luag haujlwm ntawm solder yog txhawm rau txuas cov pins tivthaiv rau cov ntsiab lus sib txuas ntawm lub rooj tsav xwm luam tawm. Kev xaiv ntawm solder muaj kev cuam tshuam zoo rau qhov zoo ntawm vuam. Niaj hnub no, feem ntau siv solder hlau yog feem ntau rosin-muaj solder hlau, tab sis lub subdivision kuj yog heev tshwj xeeb. Ntawm lawv, cov nyiaj uas muaj cov hlau nplaum uas tsis muaj dej yog qhov zoo tshaj plaws.
Tsis tas li ntawd muaj nqis mentioning yog lub solder absorber, uas yog heev tswv yim rau novices. Nws yog ib qho yooj yim kom tau solder nyob txhua qhov chaw thaum siv cov hlau soldering thawj zaug. Lub solder absorber tuaj yeem pab koj tshem tawm cov khoom siv ntau dhau ntawm lub rooj tsavxwm. Tsis tas li ntawd, lub solder absorber yog qhov zoo heev thiab muaj txiaj ntsig zoo thaum dismantling multi-pin integrated circuit devices. Nws tuaj yeem nqus tag nrho cov pob qij txha. Txawm li cas los xij, nws tsis tsim nyog kiag li rau cov neeg uas txawj siv cov hlau soldering. Ib tug soldering hlau tuaj yeem hloov nws txoj haujlwm. Cov tivthaiv tau yooj yim tshem tawm los ntawm melting deb ntawm cov pob qij txha.
Ua ntej welding, kev kho mob ua ntej yuav tsum tau ua ntawm cov khoom siv pins lossis cov khoom siv ntawm lub rooj tsavxwm. Tshem tawm cov oxide txheej ntawm qhov vuam - koj tuaj yeem siv cov hniav tawg los ua ib rab riam thiab khawb tawm cov oxide txheej ntawm cov hlau ua kom pom cov hlau nplaum ntawm tus pin. Lub rooj tsav xwm luam tawm tuaj yeem polished nrog cov ntaub nplaum zoo thiab tom qab ntawd coated nrog ib txheej ntawm rosin cawv tov. Cov khoom siv tin plating - tin plating ntawm cov hlau lead. Koj tuaj yeem poob cov hmoov txhuas hauv cov tshuaj rosin cawv, nias lub hau kub kub nrog cov tin ntawm cov hlau lead, thiab tig cov hmoov txhuas. Qhov no tso cai rau cov ua kom sib npaug plated nrog ib txheej nyias ntawm tin. Ua ntej welding cov xov hlau, lub rwb thaiv tsev sheath yuav tsum tau muab tshem tawm, thiab tom qab ntawd ob txoj kev kho saum toj no tuaj yeem ua tiav ua ntej welding. Yog hais tias nws yog ib tug hlau uas muaj ntau yam hlau hlau, nws yuav tsum tau twisted ua ntej tom qab polishing, thiab ces tinned.
