Xaiv thiab siv ib qho hluav taws xob soldering hlau
1. Sab nraud cua sov soldering hlau
Cov qauv ntawm sab nraud cua sov hluav taws xob soldering hlau yog qhia hauv daim duab 2.10. Nws yog tsim los ntawm soldering hlau taub, soldering hlau core, plhaub, ntoo kov, fais fab tuag, ntsaws thiab lwm yam. Vim hais tias lub taub hau ntawm lub taub hau yog ntsia rau hauv cov tub ntxhais hlau, nws yog hu ua lwm hom hluav taws xob hluav taws xob soldering hlau.
2. Internal cua sov soldering hlau
Cov tsos thiab cov qauv sab hauv ntawm cov hluav taws xob hluav taws xob hluav taws xob sab hauv yog pom hauv daim duab 2.11. Qhov tseem ceeb yog tsim los ntawm lub taub hau hlau, lub rhaub dej, lub pas nrig txuas, thiab tus kov. Vim tias nws cov khoom cua sov tau nruab rau hauv cov kab noj hniav ntawm lub taub hau hlau, nws hu ua cov cua sov sab hauv.
3. Kev xaiv hluav taws xob soldering hlau
Nws tuaj yeem pom los ntawm qhov nrawm dhau los uas muaj ntau hom thiab cov ntsiab lus ntawm cov hluav taws xob soldering hlau, thiab qhov ntau thiab tsawg ntawm cov workpieces yuav tsum tau welded yog txawv. Yog li ntawd, qhov kev xaiv zoo ntawm lub zog thiab hom hluav taws xob soldering hlau muaj kev sib raug zoo nrog kev txhim kho vuam zoo thiab kev ua haujlwm zoo. Yog tias qhov vuam loj dhau lawm thiab lub zog ntawm cov hlau siv hluav taws xob siv me me, qhov vuam kub qis dhau lawm, lub vuam yuav maj mam yaj, cov flux tsis tuaj yeem hloov pauv, thiab cov pob qij txha yuav tsis du thiab ruaj khov. Qhov no yuav inevitably ua rau tsis tsim nyog vuam lub zog thiab zoo li zoo, thiab txawm lub solder tsis Melted, ua welding tsis yooj yim sua.
Yog hais tias lub zog ntawm cov hluav taws xob soldering hlau siab dhau lawm, cov cua kub ntau dhau yuav raug xa mus rau lub cuab yeej yuav tsum tau welded, thiab cov pob qij txha ntawm cov khoom yuav raug overheated, ua rau cov khoom puas tsuaj, los yog ua rau cov ntawv ci tooj liab ntawm cov ntawv luam tawm. Circuit Court board poob tawm, thiab lub solder yuav nyob rau ntawm qhov chaw soldering. Kev khiav ceev dhau los tswj tau.
Kev xaiv kom raug ntawm hluav taws xob soldering hlau tuaj yeem txiav txim siab los ntawm cov hauv qab no:
1) Thaum soldering integrated circuits, transistors thiab cov khoom tsis muaj zog vim yog cua sov, yuav tsum tau siv 20-watt internal heating type lossis 25-watt external heating type electric soldering iron.
2) Thaum vuam cov xov hlau thiab coaxial cables, yuav tsum siv lub 45-75 watt sab nraud cua sov soldering hlau los yog 50 watt sab hauv cua sov soldering hlau.
3) Thaum soldering cov khoom loj dua, xws li cov hlau lead pins ntawm cov zis transformers, cov hlau lead pins ntawm cov electrolytic capacitors loj, cov av hauv av ntawm cov hlau chassis, thiab lwm yam.
4. Yuav siv cov hlau soldering li cas
(1) Yuav ua li cas tuav cov hlau soldering
Txhawm rau ua kom cov welded welded ruaj khov yam tsis tau hlawv cov khoom nyob ib puag ncig thiab cov xov hlau, nyob ntawm qhov chaw thiab qhov loj ntawm cov welded daim thiab qhov loj ntawm cov hlau soldering, nws yog ib qho tseem ceeb heev uas yuav tsum xaiv qhov tuav ntawm cov hlau soldering.
Muaj peb hom kev tuav txoj hauv kev rau hluav taws xob soldering hlau, uas yog tsim rau me me hluav taws xob soldering hlau rau vuam qhov chaw nrog me me cua sov dissipation, xws li welding Circuit Court boards ntawm lub xov tooj cua thiab TVs thiab lawv cov txij nkawm. Forehand tuav. Cov hluav taws xob soldering hlau siv nyob rau hauv txoj kev no yog loj thiab feem ntau muaj ib tug nkhaus soldering hlau taub. Txoj kev tuav rov qab yog tuav tus tuav ntawm cov hlau soldering hauv xib teg nrog tsib ntiv tes. Txoj kev no yog tsim rau high-power hluav taws xob soldering hlau vuam qhov chaw nrog loj tshav kub dissipation.
(2) Kev kho cov hlau soldering tshiab ua ntej siv
Ib tug tshiab soldering hlau tsis tuaj yeem siv tam sim ntawd. Lub hau ntawm cov hlau soldering yuav tsum tau kho ua ntej nws tuaj yeem siv tau ib txwm. Uas yog hais tias, lub ntsis ntawm cov hlau soldering yuav tsum tau coated nrog ib txheej ntawm solder ua ntej siv. Cov txheej txheem tshwj xeeb yog: ua ntej siv cov ntaub ntawv los ua cov ntaub ntawv ntawm lub taub hau ntawm cov hlau soldering rau hauv ib qho kev xav tau, tom qab ntawd txuas lub hwj huam mov, thaum qhov kub ntawm qhov taub ntawm cov hlau soldering nce mus rau qhov chaw uas nws tuaj yeem yaj cov tin, Siv rosin rau ntawm qhov kawg ntawm cov hlau soldering, thiab tom qab ntawd siv nws tom qab rosin haus luam yeeb. Thov ib txheej ntawm solder, thiab ua qhov no ob mus rau peb zaug, kom cov saum npoo ntawm cov hlau taub hau yog tag nrho cov txheej ntawm tin thiab nws yuav siv tau.
Thaum cov hlau nplaum siv rau ib lub sijhawm, cov oxide zaj duab xis yuav raug tsim rau ntawm cov hniav ntawm cov hlau taub hau thiab nws ib puag ncig, uas yuav ua rau nws nyuaj rau "noj tin". Lub sijhawm no, cov yeeb yaj kiab oxide tuaj yeem raug tshem tawm thiab rov plated nrog solder.
(3) Kev kho qhov ntev ntawm cov hlau taub hau
Tom qab xaiv lub hwj chim ntawm lub taub hau hlau, nws tau ua raws li qhov xav tau ntawm qhov kub thiab txias, tab sis nws tseem tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom nruab rau hauv lub rooj tsav xwm luam tawm. Piv txwv li, thaum welding integrated circuits thiab transistors, qhov kub ntawm lub soldering hlau taub yuav tsum tsis txhob siab dhau, thiab lub sij hawm yuav tsum tsis txhob ntev dhau. Nyob rau lub sijhawm no, qhov ntev ntawm cov hlua hlau ntxig ntxig rau ntawm cov tub ntxhais hlau soldering tuaj yeem hloov kho kom zoo los tswj qhov kub ntawm cov hlau taub hau.
(4) Kev xaiv cov hlau taub hau
Muaj ob hom soldering hlau tswv yim, ncaj thiab nkhaus. Thaum tus cwj mem tuav txoj kev tau txais yuav, cov hluav taws xob soldering hlau nrog lub taub ncaj yog hloov tau yooj yim dua rau kev siv, thiab tsim nyog rau soldering hauv circuits nrog ntau yam khoom. Nws yog tsim nyog los tuav cov hluav taws xob soldering hlau nrog nkhaus hlau taub hau, thiab nws yog feem ntau siv rau soldering thaum lub Circuit Court board yog ntsug rau lub desktop.
(5) Tiv thaiv "noj tin"
Nws tsis yooj yim rau kev siv lub zog ntawm cov hlau ntev ntev yam tsis siv nws, vim nws yooj yim rau oxidation ntawm cov tub ntxhais hlau soldering thiab hlawv nws tawm, thiab nws tseem yuav ua rau cov hlau taub hau oxidize vim cua sov ntev. , thiab txawm yuav "hlwb tuag" thiab tsis "noj tin".
(6) Hloov cov tub ntxhais hlau soldering
Thaum hloov cov tub ntxhais hlau soldering, yuav tsum ceev faj tsis txhob txuas cov hlau lead tsis raug, vim hais tias cov hluav taws xob soldering hlau muaj peb lub terminals, ib qho yog hauv av, thiab ob qho tib si txuas nrog ob lub taub hau ntawm cov tub ntxhais hlau soldering (ob lub terminals no. txuas ncaj qha mus rau 220 los ntawm txoj hlua hluav taws xob, txuas nrog lub volt AC fais fab mov). Yog tias 220-volt AC fais fab qaum txuas tsis raug rau txoj hlua khi hauv av, lub plhaub hluav taws xob hluav taws xob yuav raug them, thiab nws tseem yuav raug them thaum raug welded, kom muaj kev sib tsoo hluav taws xob. .
(7) Kev xaiv ntawm flux
Thaum soldering ib qho hluav taws xob soldering hlau, nws yog qhov zoo tshaj plaws los siv rosin flux los tiv thaiv cov hlau taub hau los ntawm corrosion. Zinc oxide thiab acidic solder roj yog ntau corrosive rau lub soldering hlau taub, uas yuav luv luv lub neej ntawm lub soldering hlau taub, yog li ntawd lawv tsis nquag siv.
