Vim li cas cov hlau nplaum ntawm cov hluav taws xob soldering hlau tsis nplaum?
Lub tshuab hluav taws xob hluav taws xob yog ib qho cuab yeej tseem ceeb rau txhua tus neeg siv hluav taws xob DIY thiab cov neeg ua haujlwm tu cov khoom siv hauv tsev. Qhov teeb meem tshwm sim feem ntau tshwm sim thaum siv yog tias lub taub hau hlau tsis noj cov tin. Rau qhov teeb meem no, ntau tus phooj ywg tsis paub dab tsi ua rau nws tsis noj tin, thiab lawv tsis paub yuav kho li cas.
Kev taw qhia thiab kev ua haujlwm ntawm hluav taws xob soldering hlau
Lub tshuab hluav taws xob hluav taws xob feem ntau yog tsim los ntawm tus kov, lub zog qaum, lub tshuab cua sov, lub taub hau hlau, thiab daim ntawv mica (qee qhov muaj tseeb kuj muaj ntau yam kub tswj Circuit Court). Raws li lawv cov txheej txheem cua sov, lawv tuaj yeem muab faib ua ob hom: sab hauv cua sov hluav taws xob soldering hlau thiab sab nraud cua sov hluav taws xob soldering hlau Cov chav kawm, uas sib haum rau cov kev siv sib txawv. Qhov laj thawj yog vim li cas nws thiaj li hu ua cov cua sov sab hauv hluav taws xob hluav taws xob yog vim lub taub hau ntawm cov cua sov sab hauv hluav taws xob hluav taws xob yog qhov hollow, thiab nws cov tub ntxhais cua sov yog nyob rau hauv lub puab hollow ntawm lub taub hau soldering, yog li nws yog hu ua ib tug. internal cua sov hom hluav taws xob soldering hlau.
Internal cua sov hom hluav taws xob soldering hlau taub, kawg hollow qauv
Sab nraud cua sov hom soldering hlau taub tsuas yog qhov sib txawv ntawm cov cua sov sab hauv hom soldering hlau. Lub taub hau ntawm sab nraud cua sov hom soldering hlau yog cov khoom thiab feem ntau ua los ntawm tooj liab. Lub cua sov tseem ceeb ntawm cov cua sov sab nraud ntawm cov cua sov soldering hlau ncaj qha qhwv lub taub hau ntawm lub taub hau, uas yog, lub taub hau ntawm cov hlau yog ntxig rau hauv cov tub ntxhais cua sov, yog li nws tseem hu ua lwm cov cua sov soldering hlau.
Externally rhuab soldering hlau taub, khoom siv
Txawm hais tias nws yog ib qho khoom siv hluav taws xob sab hauv los yog cov khoom siv hluav taws xob sab nraud, lawv txoj kev ua haujlwm yog tib yam. Lub hwj chim ntsaws ntawm lub tshuab hluav taws xob hluav taws xob qhia txog tsev neeg AC220V alternating tam sim no rau ob qho kawg ntawm cov cua sov tub ntxhais, thiab cov tub ntxhais cua sov yog energized los ua kom sov.
Ib feem me me ntawm cov cua sov tawm los ntawm cov tub ntxhais cua sov yog ploj mus rau cov huab cua nyob ib puag ncig, thiab feem ntau ntawm cov cua sov yog xa tawm mus rau lub taub hau hlau. Qhov kub ntawm cov hlau taub hau tuaj yeem ncav cuag 200-450 degrees, uas tuaj yeem yaj lub vuam rau vuam.
Vim li cas cov hlau tsis lo rau solder
1. Lub tshuab hluav taws xob hluav taws xob tau siv sijhawm ntev, cov tub ntxhais cua sov sab hauv yog kev laus lossis puas, thiab cov cua sov tawm tsis tuaj yeem ncav cuag lub melting point ntawm lub solder, uas ua rau lub soldering hlau taub tsis lo rau lub solder.
2. Thaum lub sij hawm siv txhua hnub, lub taub hau ntawm cov hlau tsis yog tinned tom qab siv cov hlau soldering, uas ua rau cov hlau taub hau oxidize nrog huab cua kub.
Oxidized dub soldering hlau taub
1. Tom qab siv hluav taws xob soldering hlau, nws tsis raug txiav tawm raws sijhawm. Cov hlau nplaum yog nyob rau hauv qhov kub thiab txias rau lub sijhawm ntev, thiab nws yuav oxidize nrog huab cua, uas ua rau cov hlau tsis yog nplaum.
2. Yuav kom nrhiav tau yooj yim nyob rau hauv txhua hnub soldering, acidic flux yog siv, uas oxidizes lub taub hau ntawm soldering hlau nyob rau hauv high kub.
3. Qhov teeb meem ntawm cov hlau soldering taub nws tus kheej. Qee cov lus qhia hlau soldering nrog cov khoom tsis zoo yog siv. Piv txwv li, qee cov lus qhia ntawm cov hlau soldering yog ua los ntawm hlau. Hom no ntawm cov hlau taub hau nws tus kheej yog qhov yooj yim heev rau oxidation.
Yuav ua li cas los daws qhov teeb meem uas lub ntsis ntawm cov hlau soldering tsis lo rau lub solder
1. Npaj cov hlau nplaum zoo, rosin, thiab daim txhuam cev kub. Tig lub hluav taws xob soldering hlau, thaum qhov kub thiab txias, ntxig lub taub hau rau hauv cov rosin, thiab co rov qab thiab tawm mus. Tom qab ntawd tshem tawm cov npaj solder thiab yaj nws nyob rau hauv kev sib cuag nrog lub ntsis ntawm lub soldering hlau.
2. Yog hais tias lub taub hau hlau tau oxidized thiab blackened, koj tuaj yeem npaj cov ntaub ntawv (yog tias tsis muaj ntaub ntawv, koj tuaj yeem npaj cov ntawv xuab zeb). Siv cov ntaub ntawv los yog cov ntawv xuab zeb los txhuam cov hlau nplaum kom tshem tawm cov txheej oxide dub rau ntawm qhov chaw ntawm cov hlau taub hau.
