Vim li cas nws thiaj li tias cov hlau tsis kub tom qab kuv tig nws?
Yog vim li cas yog vim li cas ib tug hluav taws xob soldering hlau tsis kub thaum powered on feem ntau yog vim lub hwj chim qaum poob los yog lub soldering hlau tub ntxhais hlau tawg. Thaum ntsib qhov txhaum no, R × lkn iav ntawm multimeter tuaj yeem siv los ntsuas ob qhov kawg ntawm lub hwj chim ntsaws. Yog hais tias lub multimeter pointer tsis txav, nws qhia tau hais tias ib tug qhib Circuit Court txhaum.
Ua ntej, xyuas seb puas muaj ib qho qhib Circuit Court nyob rau hauv cov coj ntawm lub plug nws tus kheej. Yog hais tias tsis yog, tshem cov roj hmab kov thiab siv ib lub multimeter los ntsuas ob qho tib si ntawm cov tub ntxhais hlau. Yog hais tias lub multimeter pointer tseem tsis txav, nws qhia tau hais tias cov tub ntxhais hlau puas thiab yuav tsum tau hloov. Tus nqi tsis kam ntawm ob qho tib si ntawm 35W sab hauv cov cua sov soldering hlau tub ntxhais yog li 1 Skfl. Yog hais tias tus nqi kuj yog ntsuas raws li ib txwm, nws qhia tau hais tias lub soldering hlau core yog zoo. Qhov txhaum tshwm sim nyob rau hauv lub hwj chim coj thiab lub ntsaws nws tus kheej, thiab feem ntau faults yog txhuas breakage.
Txhawm rau hloov cov tub ntxhais hlau soldering, ntxig ib tug tshiab soldering hlau core ntawm tib yam specification rau hauv lub connecting pas nrig, kho cov hlau lead nyob rau hauv lub fixing ntsia hlau, thiab zawm lub davhlau ya nyob twg. Nyob rau tib lub sijhawm, ceev faj kom txiav tawm qhov dhau ntawm cov tub ntxhais hlau soldering hlau los tiv thaiv kev luv luv ntawm ob txoj hlua.
Hluav taws xob soldering hlau: ib qho cuab yeej rau kev tsim hluav taws xob thiab kev kho hluav taws xob, feem ntau yog tsim los ntawm cov hlau taub hau, cov tub ntxhais hlau, lub plhaub, cov ntoo kov, lub zog txhuas, ntsaws thiab lwm yam, feem ntau yog siv rau cov khoom siv thiab cov xov hlau.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab hluav taws xob hluav taws xob: Tom qab lub hwj chim qhib, cov cua sov yog tsim los ntawm cov hlau tsis muaj zog ntawm cov tub ntxhais hlau soldering thiab xa mus rau lub taub hau hlau, uas ua rau cov hlau ua haujlwm.
Qhov laj thawj tseem ceeb yog vim li cas cov hlau tsis kub yuav yog cov hlau tsis muaj zog nyob rau hauv cov hlau taub hau yog hlawv tawm, uas yog ib qho tsis muaj zog hauv cov hlau soldering. Tsuas yog hloov cov tub ntxhais hlau soldering. Tab sis nws tsis tuaj yeem txiav txim siab qhov yuam kev nrog lub hwj chim qaum thiab ntsaws. Yog li thaum ntsib hluav taws xob soldering hlau uas tsis kub, koj yuav tsum xub siv ib lub multimeter los xyuas lub hwj chim plug thiab lub hwj chim qaum, thiab mam li xyuas lub soldering hlau core tom qab kev daws teeb meem.
