Taw qhia rau qhov sib txawv ntawm lub zog ntawm cov hluav taws xob soldering irons
Nyob rau hauv cov txheej txheem ntawm kev kho hluav taws xob, cov hluav taws xob tshuab hluav taws xob yog cov ua haujlwm tseem ceeb, tab sis ntau tus neeg saib xyuas siv los xaiv lub zog ntawm cov hlau solding thaum lub vuam txheej txheem. Feem ntau, ib lub tshuab sib dhos sib dhos rau cov neeg ntiaj teb. Qhov tshwj xeeb tshaj plaws yog tias cov nyhuv soldering tsis zoo vim tias tsis them nyiaj rau lub zog loj ntawm cov hlau solding.
Cov hluav taws xob soldering hlau siv muaj ntau lub zog, uas tuaj yeem tawg yooj yim dua li 200 degree) thiab ua rau luam tawm xov tooj los ntawm substrate; Lub zog ntawm soldering hlau siv yog tsawg dhau, cov solder tsis tuaj yeem yaj, cov pob qij txha sib luag tsis yog du thiab khov kho kom yooj yim los ua cov virtual. Feem ntau, nws yog siv rau soldering sib xyaw ua ke lub voj voog, luam tawm cov laug cam, cov tshuab kaw ntawv iC, thiab ua cov kev sim ua si hauv circuit Court. Feem ntau nws pom zoo kom siv 20W. Txog kev kho lub tshuab nqus tsev tshuab xws li lub qog ua kua thiab cov seev qub gallbladder thiab qub seev, 35W yog pom zoo. Rau cov cua kub sab nraud tshuab, 45W yog pom zoo. Rau soldering cov kab hlau ntawm loj hloov thiab av cov kab loj ntawm cov hlau substrates, hom cua sov sab hauv 50W thiab cua sov hom 75W siv. Yog tias siv cov ntaub ntawv hlau, cov cua sov sab nraud hlau hlau nrog lub zog ntawm ntau dua 100w yuav tsum tau xaiv. Yog tias cov neeg mob tso cai, cov neeg siv xov tooj cua kub tau tuaj yeem muab cov cua kub thib ib, thiab hom cua sab hauv lossis sab nraud sab nraud, uas tuaj yeem sib ntsib ntau hom vuam xav tau.
Cov ham kev siv peb siv feem ntau muab faib ua ob hom: Cov tshuaj txhuas txhuas thiab cov txhuas tsis muaj zog, tab sis feem ntau yog cov txhuas, thiab cov txhuas tsis muaj txiaj ntsig, thiab lub zog melting ntawm 183 degree. Ua cov solder dawb muaj qhov muaj pes tsawg leeg ntawm 99% tin thiab flux ntawm txog 1%, nrog lub ntsiab lus melting 227 degree. Qhov zoo ntawm cov hmoov txhuas soldering yog tsawg melting point, yooj yim soldering, thiab tus nqi qis, tab sis nws tsis yog tus phooj ywg ib puag ncig. Hmoov txhuas yog kev phom sij rau tib neeg lub cev, yog li tom qab soldering ua tiav, nws yog ib qho tsim nyog los ntxuav tes kom zoo. Thaum lub sij hawm soldering txheej txheem, nws yog qhov zoo tshaj plaws los hnav lub npog ntsej muag lossis hauv qhov chaw ci ci kom paub tseeb ntawm lub taub hau thiab qhov ua haujlwm. Nrog rau kev paub txog kev tiv thaiv kev tiv thaiv ib puag ncig ntawm cov neeg, txhuas-tsis muaj kev sib tw yog tam sim no siv rau lub tshuab vuam rau hauv lub teeb meem. Vim yog lub siab melting taw tes ntawm cov hmoov txhuas-tsis muaj kev nkag siab vim li cas nws qee zaum nyuaj rau cov khoom siv hluav taws xob txawv teb.
