Hom thiab lub zog ntawm soldering hlau thiab yuav ua li cas siv cov hlau soldering
Taw qhia rau Soldering Hlau
1. Hom thiab lub zog ntawm cov khoom siv hluav taws xob feem ntau siv
Feem ntau siv hluav taws xob soldering hlau tau muab faib ua ob hom: hom cua sov sab hauv thiab sab nraud cua sov hom. Lub taub hau ntawm cov cua sov sab hauv hom hluav taws xob soldering hlau yog sab nraum cov cua sov hlau. Qhov no hluav taws xob soldering hlau heats sai sai thiab yog lub teeb nyob rau hauv qhov hnyav. Lub taub hau ntawm cov cua sov sab nraud hluav taws xob soldering hlau yog ntxig rau hauv cov cua sov hlau. Txawm hais tias nws heats qeeb, nws tseem ruaj khov.
Lub tshuab hluav taws xob hluav taws xob yog hluav taws xob ncaj qha los ntawm 220V AC fais fab mov. Cov hlua hluav taws xob thiab rooj plaub yuav tsum tau rwb thaiv tsev, thiab qhov kev tiv thaiv ntawm cov hlua hluav taws xob thiab rooj plaub yuav tsum siab dua 200M ohms.
Electronic hobbyists feem ntau siv 30W, 35W, 40W, 45W, 50W soldering irons. Lub zog hluav taws xob muaj zog dua hlau muaj qhov hluav taws xob qis dua. Ohm's law derivation formula: R=U/I=U/I*U/U=U^2/P
2. Kev ceev faj rau kev siv hluav taws xob soldering hlau
(1) Cov hlau uas tau yuav khoom tshiab yuav tsum tau dipped rau hauv ib txheej ntawm cov tin ua ntej siv (lub zog ntawm cov hlau, thiab tom qab ntawd siv lub tin bar kom ze rau qhov kawg ntawm cov hlau soldering thaum cov hlau soldering yog rhuab mus rau ib qho chaw). Cov ntaub ntawv ci ntsa iab, tom qab ntawd tig rau hluav taws xob cua sov kom sov, dip lub taub hau ntawm cov hlau soldering nrog me ntsis rosin, thiab tin nws thaum lub rosin haus luam yeeb, kom lub ntsej muag ntawm lub taub ntawm cov hlau soldering yog thawj coated nrog ib txheej. ntawm tin.
(2) Tom qab hluav taws xob soldering hlau yog energized, qhov kub yog siab li 250 degrees Celsius. Thaum tsis siv, nws yuav tsum tau muab tso rau ntawm qhov muag muag, tab sis thaum nws tsis siv rau lub sijhawm ntev, lub zog yuav tsum raug txiav tawm kom tsis txhob muaj qhov kub ntawm qhov "hlawv" ntawm cov hlau taub hau (oxidized). Nws yog ib qho tsim nyog los tiv thaiv cov hluav taws xob soldering hlau los ntawm scalding lwm yam khoom, tshwj xeeb tshaj yog cov hlua fais fab. Yog tias cov txheej txheej rwb thaiv tsev raug kub hnyiab los ntawm cov hlau soldering yam tsis tau saib xyuas, nws yuav yooj yim ua rau muaj kev nyab xeeb.
(3) Tsis txhob ntaus cov hlau nplaum hnyav, kom tsis txhob poob siab thiab tawg cov cua sov xaim lossis cov hlau lead hauv cov hlau soldering thiab ua rau lub cev tsis zoo.
(4) Tom qab siv cov hlau soldering rau ib lub sij hawm, tej zaum yuav muaj tin av nyob rau ntawm qhov kawg ntawm cov hlau soldering. Peb tuaj yeem maj mam so nws nrog ib daim ntaub ntub dej thaum cov hlau rhuab. Yog tias muaj cov pits lossis oxidized blocks, siv cov ntaub ntawv zoo los kho lossis hloov ncaj qha rau cov hlau taub hau.
Vuam ua haujlwm posture thiab tu cev
Cov tshuaj volatilized los ntawm cua sov lub flux yog teeb meem rau tib neeg lub cev. Yog tias lub qhov ntswg nyob ze rau qhov kawg ntawm cov hlau soldering thaum lub sijhawm ua haujlwm, nws yooj yim rau nqus tau cov pa phem. Feem ntau, qhov kev ncua deb ntawm cov hlau mus rau lub qhov ntswg yuav tsum yog tsawg kawg yog tsis pub tsawg tshaj 30cm, feem ntau 40cm yog qhov tsim nyog.
Muaj peb txoj hauv kev los tuav cov hluav taws xob soldering hlau, raws li qhia hauv daim duab 1. Txoj kev tiv thaiv kev tuav yog ruaj khov hauv kev ua haujlwm, thiab nws tsis haum rau kev qaug zog tom qab ua haujlwm ntev. Nws yog qhov tsim nyog rau kev ua haujlwm ntawm high-power soldering hlau. Lub overhand tuav yog tsim rau kev khiav hauj lwm nrog nruab nrab-lub zog soldering hlau los yog hlau nrog lub kaum sab xis. Feem ntau, thaum vuam luam tawm Circuit Board thiab lwm yam weldments ntawm lub rooj ua haujlwm, tus cwj mem tuav yog feem ntau siv.
Feem ntau muaj ob txoj hauv kev los tuav cov hlau nplaum, raws li qhia hauv daim duab 2. Txij li cov hlau lead nyiaj rau qee qhov kev faib ua feem ntawm cov hlau txuas, nws paub zoo tias cov hlau lead yog cov hlau hnyav hnyav rau tib neeg lub cev, yog li koj yuav tsum hnav hnab looj tes. los yog ntxuav koj txhais tes tom qab ua haujlwm kom tsis txhob noj.
Siv cov hlau soldering los teeb tsa lub rooj zaum hlau, uas feem ntau muab tso rau ntawm sab xis ntawm lub rooj zaum ua haujlwm. Tom qab siv cov hlau soldering, nws yuav tsum tau muab tso rau ntawm cov hlau soldering kom ruaj ntseg, thiab ceev faj tsis txhob kov lub ntsis ntawm cov hlau soldering nrog cov xov hlau thiab lwm yam khoom, kom tsis txhob luv luv Circuit Court tom qab lub rwb thaiv tsev puas los ntawm cov hlau soldering. .
