Yuav ua li cas kho cov hlau nplaum uas tsis muaj cua sov tom qab siv hluav taws xob
Muaj ob qhov xwm txheej uas lub tshuab hluav taws xob hluav taws xob tsis ua kom sov tom qab siv hluav taws xob. Ib qho yog tias nws tsis ua kom sov txhua lub sijhawm tom qab tau txais lub zog, uas tej zaum yuav yog vim kev puas tsuaj rau cov tub ntxhais hlau los yog lub hwj chim qaum. Lub sijhawm no, lub tshuab hluav taws xob digital tuaj yeem siv los ntsuas qhov kev tiv thaiv ntawm cov plugs ntawm cov hlua hluav taws xob hlau. Feem ntau, qhov tsis kam ntawm cov hlau ib txwm muaj nyob nruab nrab ntawm 100 txog 2000 ohms (qhov siab dua lub zog ntawm cov hlau soldering, qhov me dua qhov ntsuas tsis kam). Yog tias qhov ntsuas tsis muaj qhov ntsuas tsis kawg, nws yuav yog vim kev puas tsuaj rau cov tub ntxhais hlau los yog lub hwj chim qaum. Tsuas yog hloov cov tub ntxhais hlau los yog lub hwj chim qaum.
Oxidized soldering hlau taub.
Yog hais tias lub soldering hlau tseem kub me ntsis rau lub sij hawm ntev tom qab lub hwj chim thiab tsis tuaj yeem yaj lub solder hlau, nws yuav yog vim ib tug tuab oxide txheej adhering rau lub puab phab ntsa ntawm lub soldering hlau taub, uas cuam tshuam lub tshav kub hloov ntawm lub soldering. hlau core mus rau lub taub hau hlau. Qee qhov pheej yig soldering irons tsis muaj kev tswj qhov kub thiab txias tsis tu ncua, thiab siv cov tooj liab soldering hlau taub qhia hauv daim duab. Thaum rhuab rau lub sij hawm ntev nrog hluav taws xob, tooj liab soldering hlau taub yog yooj yim oxidized nyob rau hauv high kub, ua ib tug siab thermal kuj oxide uas adheres rau lub puab phab ntsa ntawm lub soldering hlau taub, ua rau lub tshav kub generated los ntawm soldering hlau core. tsis tuaj yeem xa mus rau lub taub hau ntawm cov hlau zoo, thiab yog li tsis tuaj yeem yaj cov hlau solder.
Adjustable kub soldering hlau.
Yog hais tias lub taub hau hlau yog oxidized hnyav heev thiab tsis tuaj yeem vuam tau zoo, nws raug nquahu kom hloov nws nrog qhov kub thiab txias adjustable soldering hlau, vim qhov zoo ntawm cov hlau soldering muaj feem cuam tshuam rau qhov vuam zoo. Lub adjustable kub soldering hlau qhia nyob rau hauv daim duab saum toj no yog luv nqi ntawm ntau tshaj 20 yuan, nrog ib tug built-in kub tswj Circuit Court thiab ib tug alloy soldering hlau ntsis uas tsis yooj yim oxidized los yog blackened ntawm kub kub, ua rau nws yooj yim heev rau siv.
Lub tshuab hluav taws xob hluav taws xob yog tsim los ntawm ntau qhov chaw, suav nrog lub taub hau ntawm lub taub hau, lub taub hau hlau, lub plhaub hlau, ntoo (yas) kov, lub davhlau ya nyob twg ncej, thiab lub hwj chim qaum. Lub tshav kub ntawm cov hlau soldering yog cov tub ntxhais hlau uas tau nruab rau ntawm lub taub hau, uas tuaj yeem ua haujlwm ib txwm siv ntev npaum li cov tub ntxhais hlau soldering yog siv rau.
Yog hais tias cov hlau tsis kub, ua ntej siv lub multimeter los ntsuas ob tus pins ntawm lub hwj chim ntsaws. Raws li ib txwm muaj, qhov kev tiv thaiv yuav tsum nyob nruab nrab ntawm ob peb puas mus rau ntau txhiab ohms. Yog tias nws nyob hauv lub xeev qhib, koj yuav tsum qhib lub kov los xyuas seb cov hlua puas ruaj ntseg thiab txhim khu kev qha. Tom qab ntawd ntsuas lub davhlau ya nyob twg ncej,
Kev sib txuas ntawm lub davhlau ya nyob twg ncej thiab soldering hlau core lead yog ib qho chaw muaj teeb meem. Qee zaum, nws yuav zoo li qhov kev sib txuas zoo tab sis tau raug txiav tawm tiag tiag, yog li yuav tsum tau kuaj xyuas kom zoo. Yog tias cov tub ntxhais hlau soldering puas lawm, koj tuaj yeem yuav ib qho tshiab thiab hloov nws.
