Ob peb qhov sib txawv ntawm ib qho hluav taws xob hluav taws xob sab hauv thiab lub tshuab hluav taws xob sab nraud
Endothermic soldering hlau yog me dua thiab pheej yig dua. Cov khoom siv hluav taws xob dav dav siv 20W-30W sab hauv kub hom soldering hlau. Tau kawg, muaj 50W sab nraud rhuab soldering hlau tuaj yeem npaj tau. Endothermic soldering hlau cua kub efficiency yog siab dua, thiab hloov lub taub hau hlau kuj yooj yim dua.
Sab nraud cua sov hom, raws li lub npe hais tias, "sab nraud tshav kub" txhais tau tias "sab nraum zoov", vim hais tias lub tshav kub generating resistor yog sab nraud ntawm lub soldering hlau thiab thiaj li hu ua.
Nws yog tsim rau soldering ob qho tib si loj thiab me me. Vim lub cua sov resistor xaim nyob rau sab nraud ntawm lub taub hau hlau, feem ntau ntawm cov cua sov tawm mus rau qhov chaw sab nraud, yog li cov cua sov ua haujlwm qis thiab cua sov ceev yog qeeb. Feem ntau nws yuav siv sij hawm 6 mus rau 7 feeb kom preheat ua ntej vuam.
Nws lub ntim loj, vuam cov khoom siv me me zoo li tsis yooj yim. Tab sis nws muaj qhov zoo ntawm kev siv lub taub hau ntev dua thiab lub zog ntau dua, nrog rau 25W, 30W, 50W, 75W, 100W, 150W, 300W thiab lwm yam tshwj xeeb.
High-power soldering hlau feem ntau yog lwm hom cua sov. Soldering hlau yog siv rau soldering, thiaj li yuav pab tau rau kev siv, feem ntau yog ua los ntawm "solder hlau", solder hlau feem ntau muaj flux rosin.
Soldering hlau yog synthesized siv li 60% tin thiab 40% txhuas, thiab muaj ib tug tsawg melting point.
Rosin yog ib hom flux, rosin tuaj yeem pab tau soldering, cov neeg ua si erhu yuav tsum muaj, Kuv hnov tias koj tuaj yeem yuav nws ntawm lub khw muag tshuaj. Rosin tuaj yeem siv ncaj qha, tseem tuaj yeem teeb tsa rau hauv cov tshuaj rosin, uas yog, rosin crushed, muab tso rau hauv lub vial, thiab tom qab ntawd ntxiv cawv thiab do. Nco ntsoov tias cawv yog volatile, nco ntsoov kom nruj lub hau tom qab siv.
Lub raj mis tuaj yeem muab tso rau hauv ib qho me me ntawm cov paj rwb, siv cov tweezers los txiav tawm thaum siv rau cov ntawv luam tawm lossis cov khoom siv. Nco ntsoov tias muaj cov tshuaj pleev xim rau hauv kev ua lag luam (lub npe hu ua roj solder), uas yog cov khoom siv corrosive, yog siv hauv kev lag luam, tsis haum rau kev siv hluav taws xob ntau lawm. Kuj tseem muaj cov khoom lag luam muag rosin, tsis yog cov tshuaj rosin peb siv ntawm no.
