Hom thiab lub zog ntawm feem ntau siv soldering hlau
Muaj ob hom kev siv hluav taws xob soldering hlau: sab hauv thiab sab nraud. Lub taub hau hlau ntawm ib qho hluav taws xob hluav taws xob hauv hluav taws xob yog nyob sab nraud ntawm cov cua sov hlau, uas ua kom sov sai thiab sib sib zog nqus. Lub taub hau ntawm lub tshuab hluav taws xob hluav taws xob sab nraud tau muab tso rau hauv cov cua sov hlau, thiab txawm hais tias nws ua kom sov qeeb, nws tseem ruaj khov.
Cov hluav taws xob soldering hlau yog rhuab ncaj qha nrog 220V AC fais fab mov. 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. Lub tshuab hluav taws xob muaj zog heev muaj lub zog me me ntawm cov cua sov hlau. 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) Ua ntej yuav siv cov hlau uas tau muag tshiab, nws yuav tsum tau dipped rau hauv ib txheej ntawm cov tin (lub zog ntawm cov hlau soldering, thiab tom qab ntawd siv lub tin bar ze rau lub taub hau hlau thaum cov hlau soldering yog rhuab mus rau ib theem). . Tom qab siv cov hlau soldering rau lub sijhawm ntev, xa cov hlau nplaum lub taub hau ci ntsa iab, tom qab ntawd kub nws nrog hluav taws xob, thiab muab lub taub hau ntawm lub taub hau rau hauv me ntsis rosin. Thaum cov rosin haus luam yeeb, tin yuav tsum tau siv, kom ib txheej ntawm tin tuaj yeem coated rau saum npoo ntawm lub taub hau hlau ua ntej.
(2) Tom qab lub tshuab hluav taws xob siv hluav taws xob, qhov kub tuaj yeem ncav cuag 250 degrees Celsius. Thaum tsis siv, nws yuav tsum tau muab tso rau ntawm cov hlau thav duab. Txawm li cas los xij, thaum tsis siv lub sijhawm ntev, lub zog yuav tsum raug txiav tawm kom tsis txhob muaj cov hlau nplaum ntawm qhov kub thiab txias (oxidized) los ntawm qhov kub thiab txias. Txhawm rau tiv thaiv cov hluav taws xob hluav taws xob los ntawm kev puas tsuaj rau lwm yam khoom, tshwj xeeb tshaj yog cov kab hluav taws xob, yog tias cov txheej rwb thaiv tsev raug hlawv los ntawm cov hlau soldering thiab tsis ua tiag tiag, nws tuaj yeem yooj yim ua rau muaj kev nyab xeeb.
(3) Tsis txhob quab yuam cov hluav taws xob soldering hlau kom tsis txhob co cov cua sov sab hauv los yog cov hlau lead ntawm cov hlau soldering thiab ua rau malfunctions.
(4) Tom qab siv hluav taws xob soldering hlau rau ib lub sij hawm, tej zaum yuav muaj tin deposits nyob rau hauv lub taub hau ntawm lub soldering hlau. Nyob rau hauv cov cua kub ntawm cov hlau soldering, peb tuaj yeem maj mam so nws nrog ib daim ntaub ntub dej. Yog tias muaj cov pits lossis oxidation blocks, lawv yuav tsum tau kho nrog cov ntaub ntawv zoo los yog lub taub hau hlau yuav tsum tau hloov ncaj qha.
