Tsib-kauj ruam kev cob qhia txoj kev ntawm hluav taws xob soldering hlau thiab ceev faj rau kev siv hluav taws xob soldering hlau
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.
Cov hluav taws xob soldering hlau yog ncaj qha rhuab los ntawm 220V AC fais fab mov. Lub hwj chim qaum thiab rooj plaub yuav tsum tau insulated, thiab qhov kev tiv thaiv ntawm lub hwj chim qaum thiab rooj plaub yuav tsum siab tshaj 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 txoj cai muab cov mis: R=U/I=U/I*U/U=U^2/P.
Yuav ua li cas siv ib tug soldering hlau?
1. Welding lub cev thiab kev tu cev
Cov tshuaj volatilized los ntawm cua sov 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 tsawg tshaj li 30cm, feem ntau 40cm yog 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.
"Siv lub Soldering Hlau"
Feem ntau muaj ob txoj hauv kev los tuav cov hlau nplaum, raws li pom 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 taub hau 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. .
Ob, tsib-kauj ruam kev cob qhia
Raws li txoj kev cob qhia rau cov neeg pib tshiab kom paub cov cuab yeej siv hluav taws xob, txoj kev tsib-kauj ruam yog qhov zoo heev thiab tsim nyog los tham txog ib ntu.
Ntau tus neeg nyiam siv hluav taws xob rov siv cov txheej txheem ua haujlwm, uas yog, thawj zaug dip ib co solder rau ntawm qhov kawg ntawm cov hlau soldering, thiab tom qab ntawd muab cov hlau soldering rau ntawm qhov sib koom ua ke los tos kom sov thiab tom qab ntawd solder kom ntub cov vuam.
Txoj kev no tsis yog txoj kev ua haujlwm raug. Txawm hais tias qhov vuam tuaj yeem ua tau raws li qhov no, qhov zoo tsis tuaj yeem lav. Qhov no tsis yooj yim to taub los ntawm qhov peb paub txog cov txheej txheem soldering.
Thaum peb yaj lub solder mus rau lub taub hau ntawm cov hlau, cov flux nyob rau hauv lub solder hlau yuav nyob rau ntawm qhov chaw ntawm lub solder. Txij li thaum qhov kub ntawm cov hlau taub hau feem ntau yog siab tshaj 250 degree -350 degree, cov rosin flux yuav txuas ntxiv mus rau volatilize ua ntej cov hlau soldering tau muab tso rau ntawm cov khoom sib txuas. , thiab thaum lub soldering hlau muab tso rau ntawm lub solder sib koom ua ke, vim qhov kub ntawm cov welding, nws yuav siv sij hawm ib pliag kom sov. Thaum lub sij hawm no, feem ntau ntawm cov flux yuav volatilize los yog tag nrho volatilize, yog li cov txheej txheem ntub dej tsis zoo vim tsis muaj flux thaum lub sij hawm ntub dej. Nyob rau tib lub sijhawm, vim qhov sib txawv ntawm qhov kub thiab txias ntawm cov vuam thiab vuam, cov txheej txheem sib txuas tsis yooj yim rau kev tsim, thiab nws yog qhov nyuaj kom tsis txhob siv vuam virtual.
Ntxiv mus, tom qab kev tiv thaiv cov nyhuv ntawm cov flux ploj lawm, lub solder yog ib qho yooj yim rau oxidize, thiab nws yog inevitable uas qhov zoo tsis tau guaranteed.
