Txoj kev siv kom raug thiab cov txuj ci tseem ceeb ntawm hluav taws xob soldering hlau!
1. Vuam txoj kev.
Weld Check Short
(1) Tuav hluav taws xob soldering hlau ntawm sab tes xis. Siv rab koob-qhov ntswg pliers lossis tweezers nrog koj sab tes laug los tuav cov khoom lossis cov xov hlau. Ua ntej soldering, hluav taws xob soldering hlau yuav tsum tau preheated tag nrho. Tin yuav tsum tau noj rau ntawm cov hniav saum npoo ntawm lub taub hau ntawm lub taub hau, uas yog, ib qho nyiaj ntawm cov solder yuav tsum tau coj tuaj.
(2) Muab cov hniav ntawm cov hlau taub hau rau ntawm qhov sib koom ua ke. Lub tshuab hluav taws xob hluav taws xob yog nyob ntawm kaum ntawm 60 degree rau lub dav hlau kab rov tav. Txhawm rau kom yooj yim rau kev khiav ntawm molten tin los ntawm qhov kawg ntawm cov hlau soldering mus rau qhov sib koom ua ke. Lub sij hawm lub taub hau hlau nyob ntawm qhov sib koom ua ke yog tswj tsis pub dhau 2 mus rau 3 vib nas this.
(3) Nqa lub taub hau ntawm cov hlau soldering. Sab laug tes tseem tuav cov khoom. Sab laug tes tsuas yog tso tawm tom qab lub tin ntawm lub solder sib koom yog txias thiab solidified.
(4) Tig cov hlau lead nrog tweezers kom paub meej tias nws tsis xoob, thiab tom qab ntawd siv cov pliers txiav tawm cov hlau lead ntau dhau.
2. Vuam zoo
Thaum welding, nws yog ib qho tsim nyog los xyuas kom meej tias txhua qhov sib koom ua ke yog ruaj khov thiab sib cuag zoo. Los xyuas kom meej qhov zoo ntawm vuam.
Ib tug zoo solder sib koom yuav tsum kaj, du thiab tsis muaj burrs, thiab tus nqi ntawm cov tin yuav tsum nyob nruab nrab. Tin thiab solder yog nrees fused. Yuav tsum tsis muaj kev vuam cuav thiab vuam cuav.
False soldering txhais tau hais tias tsuas yog ib qho me me ntawm cov tin yog welded ntawm qhov sib koom ua ke, ua rau muaj kev sib cuag tsis zoo thiab cuam tshuam rau thiab tawm. False welding txhais tau hais tias nws zoo li welded rau saum npoo, tab sis nws tsis yog welded. Qee zaum cov hlau lead tuaj yeem rub tawm los ntawm kev sib koom ua ke los ntawm kev rub tawm ntawm tes. Ob qhov xwm txheej no yuav ua rau muaj teeb meem loj rau kev debugging thiab kev saib xyuas ntawm cov khoom siv hluav taws xob. Ob leeg ntawm cov xwm txheej no tsuas yog zam tau nrog kev siv dav dav, ua tib zoo siv vuam.
Thaum soldering lub Circuit Court board, nco ntsoov tswj lub sij hawm. Yog tias nws ntev dhau lawm, lub rooj tsav xwm Circuit Court yuav raug hlawv, lossis daim ntawv tooj liab yuav poob. Thaum tshem cov khoom los ntawm lub rooj tsav xwm hauv Circuit Court, lo lub hau ntawm cov hluav taws xob soldering hlau rau ntawm qhov sib koom ua ke, thiab rub tawm cov khoom tom qab cov tin ntawm cov khoom sib koom ua ke.
Flux (rosin thiab solder roj) yog tus yuam sij thaum soldering. Cov rosin tshiab thiab cov roj uas tsis muaj corrosive tuaj yeem pab koj ua kom tiav qhov zoo, thiab tuaj yeem ua kom lub ntsej muag huv si thiab zoo nkauj. Koj tuaj yeem siv ntau flux thaum koj siv nws
3. Kev txawj vuam
Thaum lub sij hawm tu fabrication txheej txheem, vuam ua hauj lwm yog qhov tseem ceeb. Nws tsis tsuas yog yuav tsum tau kho cov khoom ntawm lub rooj tsavxwm, tab sis kuj xav kom cov pob qij txha yuav tsum ruaj thiab du. Yog li ntawd, qhov zoo ntawm vuam tshuab ncaj qha cuam tshuam rau kev ua tiav ntawm kev tsim hluav taws xob. Yog li ntawd, vuam tshuab yog ib qho kev txawj ntse uas txhua tus neeg siv khoom siv hluav taws xob yuav tsum paub. Tam sim no qhia cov ntsiab lus tseem ceeb ntawm vuam:
1). Kev xaiv ntawm hluav taws xob soldering hlau
Lub zog ntawm cov hlau soldering yuav tsum tau txiav txim siab los ntawm qhov loj ntawm qhov taw tes soldering. Lub cheeb tsam ntawm qhov taw tes soldering yog loj, thiab qhov kub dissipation ceev ntawm lub soldering point kuj yog ceev, yog li lub zog ntawm cov hlau soldering yuav tsum loj dua. Feem ntau, lub zog ntawm cov hluav taws xob hluav taws xob yog 20W 25W 30W 35W 50W thiab lwm yam. Nws yog qhov tsim nyog xaiv lub zog ntawm 30W.
Tom qab cov hluav taws xob soldering hlau tau siv rau lub sijhawm ntev, ib txheej ntawm oxide yuav raug tsim rau ntawm qhov kawg ntawm cov hlau soldering. Lub sijhawm no, nws tsis yooj yim rau noj tin. Lub sijhawm no, koj tuaj yeem siv cov ntaub ntawv los ua cov txheej txheem oxide. Tom qab cov hlau soldering yog powered on, ntxig lub rosin thaum lub ntsis ntawm cov hlau soldering yog kub me ntsis. , Koj tuaj yeem siv nws txuas ntxiv tom qab siv cov khoom siv, thiab cov khoom siv hluav taws xob tshiab yuav tsum tau tinned ua ntej nws tuaj yeem siv tau.
2). Solder thiab flux
Xaiv cov hlau nplaum uas muaj cov ntsiab lus melting tsawg thiab tsis muaj corrosive flux, xws li rosin. Nws tsis tsim nyog siv cov khoom lag luam thiab corrosive acid solder roj. Nws yog qhov zoo dua los siv cov hlau nplaum uas muaj rosin, uas yooj yim heev rau siv.
3). Vuam txoj kev
Cheebtsam yuav tsum tau ntxuav thiab tinned. Cov khoom siv hluav taws xob yog nyob rau hauv cia. Vim yog cov nyhuv ntawm huab cua oxidation, ib txheej ntawm oxide zaj duab xis yog txuas rau cov khoom siv pins, thiab muaj lwm cov av. Ua ntej vuam, cov oxide zaj duab xis tuaj yeem raug khawb tawm nrog rab riam, thiab ib txheej yuav tsum tau thov tam sim ntawd. Solder (feem ntau hu ua enamel), thiab ces solder. Tom qab cov kev kho mob saum toj no, cov khoom siv yog yooj yim rau welding kom ruaj khov, thiab qhov tshwm sim ntawm kev vuam virtual tsis yooj yim tshwm sim.
soldering kub thiab soldering lub sij hawm
Thaum soldering, qhov kub ntawm cov hluav taws xob soldering hlau yuav tsum siab tshaj qhov kub ntawm lub solder, tab sis nws yuav tsum tsis txhob siab dhau. Nws yog qhov zoo dua tias cov hlau nplaum txuas nrog cov rosin ua ntej haus luam yeeb. Yog hais tias lub sij hawm soldering yog luv luv, qhov kub ntawm cov pob qij txha yog tsawg heev, cov pob qij txha solder tsis tag melted, thiab cov pob qij txha solder yog ntxhib thiab yooj yim los ua cuav soldering. Ntawm qhov tsis sib xws, lub sij hawm soldering yog ntev dhau lawm, lub solder yog yooj yim ntws, thiab nws yog ib qho yooj yim uas yuav ua rau lub Cheebtsam overheat thiab puas lub Cheebtsam.
Tus nqi ntawm cov tin ntawm lub solder sib koom
Tus nqi ntawm solder ntawm qhov taw tes soldering yuav tsum tsis txhob me heev, yog hais tias nws yog me me, lub vuam yuav tsis muaj zog, thiab cov neeg kho tshuab lub zog yuav tsis zoo heev. Thiab ntau dhau yog ib qho yooj yim ua rau ntau qhov tsos tab sis tsis txuas nrog sab hauv. Lub solder yuav tsum cia li submerge tag nrho cov tivthaiv ua nyob rau hauv lub soldering point, thiab cov qauv yuav tsum faintly pom.
Ua tib zoo saib rau txoj hauj lwm ntawm cov hlau soldering thiab qhov taw tes soldering
Thaum cov neeg pib siv lub vuam, lawv feem ntau txav cov hlau rov qab los yog nyem nyuaj ntawm qhov chaw soldering. Txoj kev no tsis yog lawm. Txoj kev raug yog siv cov tin-coated nto ntawm cov hluav taws xob soldering hlau los kov lub soldering point, kom lub tshav kub hloov chaw yog loj thiab vuam ceev.
4). Kev tshuaj xyuas tom qab vuam
Tom qab soldering, nws yog ib qhov tsim nyog los xyuas seb puas muaj cov soldering uas ploj lawm, virtual soldering, thiab cov khoom luv luv Circuit Court tshwm sim los ntawm solder flow. Vuam tsis yooj yim nrhiav tau, koj tuaj yeem siv cov tweezers los tuav cov pins tivthaiv thiab rub nws maj mam, yog tias koj pom tshee, koj yuav tsum kho lub soldering tam sim ntawd.
