Dab tsi ua rau hluav taws xob soldering hlau tsis kub tom qab qee lub sijhawm tsis ua haujlwm?
1. Tsis kub kiag li
Yog tias nws tsis kub, siv cov hluav taws xob tiv thaiv ntawm multimeter los ntsuas qhov tsis kam ntawm lub hwj huam qaum ntsaws, nws yuav tsum yog ∞. Disassemble lub hluav taws xob soldering hlau, tshem tawm los yog tev tawm lub tes tsho insulating ntawm kev sib txuas ntawm lub hwj chim qaum thiab cov tub ntxhais soldering hlau, ntsuas qhov tsis kam ntawm ob lub ntsiab lus, yog tias muaj qhov tsis kam, nws txhais tau tias cov tub ntxhais ntawm cov hluav taws xob soldering hlau. zoo, thiab nws yog qhov teeb meem ntawm txoj hlua hluav taws xob — —— Nws raug rub tawm lossis muaj kev sib cuag tsis zoo hauv lub ntsaws. Yog hais tias tus nqi kuj tseem yog ∞, nws txhais tau hais tias lub soldering hlau core puas lawm. Cov nram qab no yog ob qho tib si soldering hlau cores: sab nraud cua sov hom thiab sab hauv cua sov hom.
Yog vim li cas rau kev puas tsuaj ntawm chromium hlau core: ●Vim yog ntog thiab khob. Txij li thaum lub cua sov hlau ntawm chromium-hlau core yog qhov txhab ntawm lub quartz los yog nyob rau hauv lub ceramic raj, cov ntaub ntawv insulating yog inherently nkig, thiab ua ntau nkig ib zaug rhuab, thiab tsis tuaj yeem kov los yog ntog, txwv tsis pub, lawv yuav tawg thiab ua rau kev puas tsuaj. . ●Qhov zoo ntawm cov hlau soldering nws tus kheej yog qhov tsis zoo, thiab cov cua sov xaim tau tawg. Tam sim no nyob rau hauv kev ua lag luam, hluav taws xob soldering hlau uas raug nqi 3 mus rau 5 yuan ib thooj tau pib zoo ib yam li cov uas raug nqi kaum tawm yuan ib thooj. Lawv tuaj yeem raug faked, tab sis qhov zoo tsis zoo thiab tsis ruaj khov. Cov neeg feem ntau hais tias "koj tau txais yam koj them rau," thiab nws muaj tseeb.
2. Nws tuaj yeem ua kom sov, tab sis cov cua sov tsis txaus los yaj cov tin
Cov yam ntxwv ntawm qhov tshwm sim yog tias cov hlau soldering muaj cov plaub hau dub thiab tsis tuaj yeem yaj lub solder. Nws zoo nkaus li tias cov cua sov tsis txaus, tab sis qhov tseeb ntawm qhov kawg ntawm cov hlau soldering yog "kub kom tuag".
Yog hais tias qhov no tshwm sim, dipped lub soldering hlau uas tseem ua cua sov nrog rosin dua thiab rub nws nyob rau hauv lub tin block kom txog thaum lub ntsis ntawm lub soldering hlau yog tinned, uas yog, cov xim hloov ntawm dub mus rau kaj. Rau lub neej ntev hluav taws xob soldering hlau nrog lub ntsiab lus taw qhia, nws yog nruj me ntsis txwv tsis pub siv cov ntaub ntawv los ua ntaub ntawv, vim tias lub taub hau alloy yuav raug foob.
Lub taub thiab cov tub ntxhais ntawm cov hlau soldering yog cov khoom siv, thiab kev puas tsuaj yog qhov tshwm sim ib txwm muaj, tab sis kev paub txog kev siv cov hlau soldering yuav ua rau nws lub neej ntev.
