Hom thiab lub zog ntawm soldering hlau thiab yuav siv li cas
Taw qhia rau soldering hlau
1. Hom thiab lub hwj chim ntawm cov khoom siv uas nquag siv
Feem ntau siv cov hlau soldering tau muab faib ua ob hom: hom cua sov sab hauv thiab sab nraud cua sov hom. Lub taub hau ntawm ib qho khoom siv hluav taws xob hauv tsev yog sab nraum cov cua sov hlau. Hom soldering hlau no heats sai sai thiab yog lub teeb yuag. Lub taub hau ntawm sab nraud rhuab soldering hlau yog ntxig rau hauv cov cua sov hlau. Txawm hais tias nws heats qeeb, nws kuj muaj zog.
Cov hlau soldering yog rhuab ncaj qha nrog 220V AC zog. Lub hwj chim qaum thiab lub casing yuav tsum tau insulated, thiab qhov kev tiv thaiv ntawm lub hwj chim qaum thiab lub casing yuav tsum siab tshaj 200M ohms.
Electronics enthusiasts feem ntau siv 30W, 35W, 40W, 45W, thiab 50W soldering irons. Ib tug muaj zog soldering hlau muaj ib tug me me cua sov hlau kuj. Ohm txoj cai muab cov qauv: R=U/I=U/I*U/U=U^2/P
2. Kev ceev faj rau kev siv cov hlau soldering
(1) Cov hlau uas tau muag tshiab yuav tsum tau dipped rau hauv ib txheej ntawm cov tin ua ntej siv (lub hwj chim ntawm cov hlau soldering, thiab tom qab ntawd siv lub tin bar ze rau lub ntsis thaum cov hlau soldering yog rhuab mus rau ib theem). Yog hais tias cov hlau soldering tau siv ntev heev, lub hau ntawm cov hlau soldering yuav tsum tau ua ntaub ntawv nws ci ntsa iab, ces tig rau hluav taws xob kom sov nws, thiab dilute lub soldering hlau taub hauv me ntsis rosin. Thaum cov rosin haus luam yeeb, thov cov tin, kom lub ntsej muag ntawm cov hlau taub hau yog thawj plated nrog ib txheej ntawm tin.
(2) Qhov kub ntawm cov hluav taws xob soldering hlau nce mus txog 250 degrees Celsius tom qab nws tau siv. Nws yuav tsum tau muab tso rau ntawm cov hlau soldering thaum tsis siv. Txawm li cas los xij, thaum tsis siv lub sijhawm ntev, cov khoom siv hluav taws xob yuav tsum raug txiav tawm kom tsis txhob cuam tshuam cov hlau nplaum ntawm qhov "hlawv" (oxidized) los ntawm qhov kub thiab txias. Nws yog ib qho tsim nyog los tiv thaiv cov hlau los ntawm kev kub hnyiab lwm yam, tshwj xeeb tshaj yog cov hlua hluav taws xob. 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 soldering nyuaj kom tsis txhob tawg cov cua sov xaim lossis cov hlau lead hauv cov hlau soldering thiab ua rau tsis ua haujlwm.
(4) Tom qab cov hlau nplaum tau siv rau ib lub sijhawm, tej zaum yuav muaj cov nplais ntawm lub taub hau ntawm cov hlau. Peb tuaj yeem maj mam so nws nrog daim ntaub ntub dej thaum lub hlau soldering yog rhuab. Yog tias muaj cov pits lossis oxide blocks, siv cov ntaub ntawv zoo los kho lawv lossis hloov lub taub hau hlau ncaj qha.
Vuam ua haujlwm posture thiab tu cev
Cov tshuaj chemical emissions thaum lub flux yog rhuab yog teeb meem rau tib neeg lub cev. Yog tias lub qhov ntswg nyob ze rau ntawm lub taub hau ntawm lub taub hau thaum ua haujlwm, nws yooj yim rau nqus tau cov pa phem. Feem ntau, qhov kev ncua deb ntawm cov hlau thiab lub qhov ntswg yuav tsum yog tsawg kawg 30cm, feem ntau 40cm yog qhov tsim nyog.
