Ntau lub tshuab hluav taws xob hauv tsev yog tsim nrog lub taub tooj. Piv txwv li, soldering hlau xws li EPSN. Lub taub hau tooj liab yuav tsum tau kho kom zoo ua ntej cov hlau tuaj yeem siv tau. Lub sting yuav tsum tau muab ib daim ntawv yooj yim rau soldering.
Qee tus neeg ua nws nrog cov ntaub ntawv yooj yim, thiab tshwj xeeb tshaj yog cov neeg muaj tswv yim nyiam ua nws. Yog li ntawd, lub hau ntawm cov hlau soldering ua ntau ruaj thiab nws cov yaj nyob rau hauv solder tshwm sim ntau tsawg thaum lub sij hawm soldering txheej txheem. Tab sis tsis ntev los sis tom qab ntawd txhua leej txhua tus xav paub yuav ua li cas tin ib lub taub hau tooj liab.
Txhim kho cov hlau nplaum
Nws yog qhov zoo tshaj plaws los yuav cov hlau nplaum uas lub hau txuas nrog cov ntsia hlau tshwj xeeb. Xws li ib qho sting tuaj yeem yooj yim tshem tawm thiab rov ua dua. Tau kawg, yog tias nws sticks thaum siv, ces cov txheej txheem no yuav tsis yooj yim li. Yog li ntawd, thaum siv cov hlau soldering nrog cov lus qhia tshem tau, nws yog ib qho tsim nyog yuav tsum tshem tawm lawv ib ntus thiab ntxuav qhov txuas kom nws tsis txhob lo.
Tom qab sting yog muab txoj caidaim ntawv, nws yuav tsum tau tinned. Cov kab lus "yuav ua li cas rau tin ib lub taub hau soldering" yuav tsum to taub raws li npog qhov chaw ua hauj lwm ntawm lub ntsis nrog ib tug nyias txheej ntawm solder. Nws tsis nyuaj dhau ua qhov no. Nws yog txaus los qhib cov hlau nplaum nyob rau hauv lub network, tos kom txog thaum nws sov mus txog qhov kub thiab txias uas cov rosin pib yaj, thiab tom qab ntawd muab cov hlua khi rau hauv nws.
Tom qab cov hlau tau sov so rau nws qhov kev ua haujlwm kub, koj yuav tsum tau npog ib feem ntawm nws uas tau soldered los ntawm txhua sab nrog solder. Nws yog qhov zoo dua los siv cov khoom me me los yog solder ua nyob rau hauv daim ntawv ntawm ib tug hlau rau qhov no. Lub tshuab hluav taws xob nrog lub zog ntawm 25 watts yuav tsis tuaj yeem yaj ib daim loj ntawm solder.
Solder tip shape
Cov duab ntawm tus sting tej zaum yuav txawv. Kev xaiv yog nyob ntawm tus cwj pwm ntawm tus neeg siv cov hlau soldering, thiab, ntawm chav kawm, ntawm hom kev ua haujlwm nrog nws. Qee tus nyiam lub khob zoo li lub taub hau, lwm tus yog 45-degree txiav taub.
Qhov tseeb yog tias txawm tias cov transistors muab zais rau hauv SOT-23 rooj plaub, SMD qhov chaw lossis cov khoom siv hluav taws xob nrog 1206 qhov loj me tuaj yeem raug soldered nrog lub ntsej muag ntse hlau taub hau. Nyob rau hauv nws tsis muaj, ib tug zoo tib yam soldering hlau nrog lub hwj chim ntawm txog 25 watts, nyob rau hauv uas lub taub yog ua tiav nyob rau hauv daim ntawv ntawm tsab ntawv P, yog ib qho tseem ceeb.
Qhov no yog ua kom tsis txhob overheat cov lus xaus ntawm ib feem, uas tshwm sim thaum soldering nrog ib tug soldering hlaukev hlub tshua. Thiab nrog kev pab los ntawm xws li ib tug U-shaped sting, cov hlau lead yog soldered ua ke tam sim ntawd, thiab ib feem yog yooj yim tso tawm los ntawm lub soldering point.
Nws yog qhov zoo dua los siv cov hlau nplaum uas muaj zog dua thaum ua haujlwm loj ntawm cov khoom siv hauv xov tooj cua, thaum siv lub tshuab hluav taws xob. Nws tsis yog qhov nyuaj ua rau koj tus kheej. Nyob rau hauv cov ntaub ntawv no, ib tug soldering hlau nrog lub hwj chim txog li 65 watts yuav ua.
Muaj ntau zaus thaum rosin dheev pib haus luam yeeb thaum soldering. Qhov no txhais tau hais tias cov hlau soldering yog overheated. Koj yuav tsum tua nws ntawm lub network thiab tos kom txog thaum nws txias. Nyob rau tib lub sij hawm, yog hais tias lub soldering hlau cools down hauv qab ib txwm, nws pib solder tsis zoo. Siv lub tshuab hluav taws xob, cov teeb meem no tuaj yeem zam tau yooj yim, thiab kev ua haujlwm tau yooj yim dua, thiab los ntawm qhov tsim nyog ua ntej ua haujlwm yuav tsis muaj dab tsi ntxiv tab sis mus rau tin lub taub hau.
Ntxhais hlau
- Lub taub hau hlau yog ntse nrog cov ntaub ntawv ntawm lub kaum sab xis ntawm 30-40 degrees.
- ntug sab laug 1 hli dav thiab me ntsis blunt.
- Ntawm cov hlau nplaum tshiab, koj tsuas yog yuav tsum tau xuab zeb lub taub nrog cov ntawv xuab zeb zoo kom tshem tawm cov patina. Patina yog ntsuab tooj liab oxide.
- Yog hais tias lub khw sharpening tsis haum koj, ces koj yuav tsum tau tshem tawm cov sting thiab forge nws tus kheej, muab nws cov duab ntawm ib tug concave lub xub pwg hniav. Txoj kev no muaj lwm qhov ntxiv - cov hlau yuav dhau los ua qhov tsis zoo rau corrosion.
- Yuav kom muab lub sting saib ua tiav, nws tseem yuav ua nws nrog cov ntaub ntawv nrog cov ntawv nplua zoo.
Yuav ua li cas tin lub taub hau ntawm qhov chaw nres tsheb?
Tinning ib lub ntsis txhais tau tias npog nws nrog ib txheej nyias ntawm solder. Rau qhov no koj xav tau:
- Tig rau ntawm cov hlau nplaum thiab tos kom txog thaum tus pas tooj liab hloov xim liab-txiv kab ntxwv. Tsis tsim nyog tos lawm, vim tus pas nrig yuav hlawv.
- Dip tag nrho cov lus hauv rosin thiab yaj ib qho me me ntawm cov solder.
- Txheej txheem nrog solder tag nrho nto ntawm sting. Nws yuav tsho zoo dua yog tias koj rub nws tawm tsam ntoo ua ntej.
Yuav ua li cas tinger fireproof?
Ntawm kev muag khoom koj tuaj yeem nrhiav cov hlau nplaum uas ua haujlwm tau them nrog cov khoom siv hluav taws kub tshwj xeeb. Cov txheej no nyias nyias thiab tsis muaj qhov yuav tsum tau ntxuav, zoo li cov ntaub ntawv nrog cov pa roj hmab. Cov lus nug tshwm sim: "Yuav ua li cas rau tin lub taub hau yog tias nws tsis tuaj yeem ntxuav tau li niaj zaus?" Nws yog ib qho tsim nyog yuav tau siv daim txhuam cev tshwj xeeb. Ib qho uas cov niam tsev feem ntau ntxuav tais diav, los yog ib daim ntaub yav tas los soaked hauv dej, kuj tsim nyog. Thaum siv cov hlau nplaum zoo li no, nws yuav tsum nco ntsoov tias txhua yam khoom siv cuam tshuam txo lawv lub neej kev pab cuam.
txhawm rau txhawm rau txhawm rau qhov taub ntawm cov hlau zoo li no, koj yuav tsum tau dipped ib daim hlau rau hauv cov rosin molten, rub lub taub hau ntawm daim ntaub ntub dej, tshem tawm cov oxides ntawm nws, thiab tom qab ntawd txav cov rhuab soldering hlau hla lub hau. solder. Tom qab tinning, nws tseem los so lub taub nrog ib daim ntaub, thiab cov hlau soldering yog npaj ua haujlwm.
Thaum ua hauj lwm nrog txhua yam ntawm cov hlau soldering, koj yuav tsum sim kom tsis txhob overheat lawv saum 300 degrees C, txwv tsis pub koj yuav tsum tau.rov koom nrog tinning lub sting. Thiab tau kawg, txhua tus neeg uas siv cov hlau soldering yuav tsum paub yuav ua li cas thiaj li ua tau zoo tin lub taub hau.
