Kev siv thiab ceev faj ntawm hluav taws xob soldering hlau
Hluav taws xob soldering hlau yog ib qho khoom siv vuam tsis tseem ceeb hauv kev tsim thiab tu cov khoom siv hluav taws xob. Lub tshuab hluav taws xob hluav taws xob feem ntau yog siv hluav taws xob cua sov los yog PTC cov khoom siv cua sov los tsim lub zog hluav taws xob, thiab hloov cov cua sov mus rau lub taub hau taub hau kom ua tiav vuam. Muaj ntau hom hluav taws xob soldering hlau, nrog rau cov cua sov sab hauv, cua sov sab nraud, thiab hluav taws xob tsis tu ncua.
Siv. Ua ntej siv lub tshuab hluav taws xob tshiab, siv lub tshuab multimeter los ntsuas tus nqi tiv thaiv ntawm ob qho kawg ntawm lub hwj chim qaum. Yog tias tus nqi tsis kam yog xoom, nws qhia tau hais tias muaj kev sib tsoo hauv cov hlau thiab yuav tsum tau muab tshem tawm. Tshem tawm cov xaim thiab ntsaws nws dua; Yog hais tias tus nqi kuj yog infinite, feem ntau ntawm lub sij hawm soldering hlau core los yog txhuas hlau yog tawg; Yog hais tias tus nqi kuj nyob ib ncig ntawm 3K Ω, ntsaws lub hwj chim dua, thiab tom qab ob peb feeb ntawm lub hwj chim rau, khaws cov hlau soldering thiab poob rau hauv lub rosin. Feem ntau, yuav tsum muaj pa luam yeeb thiab lub suab "squeaking". Lub sij hawm no, poob rau hauv lub tin dua thiab cia lub tin tag nrho poob rau hauv cov hlau soldering ua ntej welding.
Ceeb Toom: Nws yog ib qho tsim nyog yuav tsum tau ua ntej dip lub taub hau taub hau hauv rosin ua ntej siv hluav taws xob los tiv thaiv oxidation ntawm lub taub hau hlau, yog li txuas nws lub neej kev pab cuam.
Vuam. Kev khaws cov hluav taws xob soldering hlau tsis tuaj yeem welded tam sim ntawd. Koj yuav tsum xub dip nws nyob rau hauv rosin los yog solder paste (soldering roj). (Lub hom phiaj yog tshem tawm cov av ntawm lub taub hau hlau, thiab qhov thib ob yog sim ntsuas qhov kub), thiab tom qab ntawd poob rau hauv tin. Cov pib tshiab yuav tsum tsim tus cwj pwm zoo no. Cov khoom yuav tsum tau welded yuav tsum tau coated nrog me ntsis vuam roj ua ntej, thiab cov khoom qias neeg heev yuav tsum tau ntxuav ua ntej, thiab ces dipped nyob rau hauv vuam roj rau welding. Vuam roj yuav tsum tsis txhob siv ntau dhau lawm, txwv tsis pub nws yuav corrode lub rooj tsav xwm Circuit Court thiab ua rau nyuaj rau kho qhov tsis raug. Sim siv rosin vuam ntau li ntau tau. Tom qab hluav taws xob soldering hlau yog powered on, qhov chaw ntawm lub taub hau ntawm lub soldering hlau yuav tsum siab tshaj qhov kov, txwv tsis pub tus kov yuav hlawv tawm yooj yim. Yog hais tias hluav taws xob soldering hlau overheats, lub taub hau soldering hlau yuav tsum tau rub tawm me ntsis ntawm lub plhaub tseem ceeb; Yog tias qhov ntsuas kub tsawg dhau (thaum lub zog hluav taws xob qis, nws tsis yooj yim rau yaj tin) kom ntseeg tau tias vuam zoo, lub taub hau hlau tuaj yeem muab tso rau sab hauv kom tau txais qhov ntsuas kub zoo. Thaum vuam cov khoom xws li cov kav dej thiab cov khoom siv sib xyaw ua ke, nws yog ib qho tseem ceeb kom tsis txhob ua rau cov khoom puas. Txawm li cas los xij, nws yog ib qho tsim nyog yuav tsum tau tos kom lub solder kom yaj tag rau hauv Circuit Court board thiab qhov chaw ua ntej tshem cov hlau soldering, txwv tsis pub nws yuav ua rau tsis muaj tseeb soldering thiab coj sequelae mus kho.
