Txoj cai ntawm Far Infrared Thermometer Performance Index ntawm Far Infrared Thermometer
Ua ntej vuam ua haujlwm
Muab cov ntaub so ntswg ntub nrog dej ua ntej, ces nyem tawm cov dej ntau dhau. Tsuas yog nyob rau hauv txoj kev no tuaj yeem lub taub hau ntawm cov hlau soldering tau txais cov txiaj ntsig zoo tshaj plaws. Yog tias koj siv daim txhuam cev tsis ntub dej, nws yuav ua rau lub taub hau ntawm cov hlau tsis huv thiab ua rau nws tsis tuaj yeem tin.
Thaum ua haujlwm soldering, cov txheej txheem vuam hauv qab no tuaj yeem tiv thaiv qhov kawg ntawm cov hlau soldering thiab txo cov oxidation tus nqi.
Tom qab vuam ua haujlwm
Ua ntej kho qhov kub kom txog li 250 degree, tom qab ntawd ntxuav lub hau ntawm cov hlau soldering, thiab tom qab ntawd ntxiv txheej tshiab ntawm tin rau kev tiv thaiv. (Yog tias koj siv cov hlau tsis muaj qhov kub thiab txias, txiav tawm lub hwj chim ua ntej, thiab cia qhov kub ntawm cov hlau taub hau poob me ntsis ua ntej tinning.)
Sim siv qhov kub thiab txias soldering
Qhov kub thiab txias yuav ua kom cov oxidation ntawm cov hlau taub hau thiab txo lub neej ntawm cov hlau taub hau. Yog hais tias qhov kub ntawm cov hlau taub hau tshaj 470 degree, nws yuav oxidize ob zaug sai li 380 degree.
Thaum soldering, tsis txhob siv lub zog ntau dhau, txwv tsis pub lub hau ntawm cov hlau yuav puas thiab deformed. Ntev npaum li lub taub hau hlau tuaj yeem tiv tauj rau qhov sib koom ua ke, cov cua sov tuaj yeem hloov mus. Tsis tas li ntawd, xaiv txoj cai soldering hlau taub kuj tuaj yeem pab hloov cov cua sov.
Nco ntsoov khaws cov hlau taub hau tinned
Qhov no tuaj yeem txo txoj hauv kev ntawm oxidation ntawm lub taub hau hlau thiab ua kom cov hlau taub hau ntev dua. Tom qab siv, cov khoom siv tshiab yuav tsum tau muab ntxiv tom qab qhov kub ntawm cov hlau taub hau tau poob me ntsis, kom cov tin plating txheej muaj cov nyhuv zoo dua los tiv thaiv oxidation.
Khaws lub hau ntawm cov hlau soldering huv si thiab tshem tawm cov oxides tam sim ntawd
Yog tias muaj cov oxide dub ntawm lub taub, lub hau yuav tsis tau tinned thiab yuav tsum tau ntxuav tam sim ntawd. Thaum ntxuav, ua ntej kho qhov kub ntawm lub taub hau ntawm lub taub hau kom txog 250 degree, tom qab ntawd ntxuav cov hlau taub hau nrog ib daim txhuam cev ntxuav, thiab tom qab ntawd tin nws. Rov ua qhov kev txiav txim kom txog thaum cov oxide raug ntxuav.
Siv cov dej ua haujlwm qis
Fluxes nrog kev txav siab los yog muaj zog corrosiveness yuav ua rau kom qhov corrosion ntawm cov hlau taub hau thaum rhuab, yog li tsis tshua muaj corrosive fluxes yuav tsum tau xaiv.
Muab cov hlau nplaum tso rau ntawm qhov muag muag
Thaum cov hlau tsis siv, cov hlau nplaum yuav tsum tau ua tib zoo muab tso rau ntawm cov hlau uas tsim nyog los tiv thaiv cov hlau taub hau los ntawm kev sib tsoo.
