Yuav ua li cas xaiv reflow soldering?

Kuv ntseeg tias ntau tus phooj ywg yuav entangled heev thaum xaiv reflow soldering.Lawv tsis paub yuav xaiv li cas, tshwj xeeb tshaj yog cov phooj ywg uas tsis paub reflow soldering txawm ntau tsis meej pem.Tsis txhob txhawj tam sim no.Cia peb qhia luv luv yuav ua li cas.Xaiv txoj kev ntawm reflow soldering:

1. Txheeb xyuas qhov kev ua haujlwm ntawm rwb thaiv tsev ntawm lub qhov cub reflow.

Lub qhov cub zoo reflow muaj kev txuag hluav taws xob zoo thiab kev ua haujlwm siab thermal, tab sis qhov cub tsis zoo reflow tsis muaj qhov zoo li no.Txawm hais tias qhov thermal efficiency ntawm qhov cub reflow yog qhov nyuaj rau kev ntsuas, koj tuaj yeem kov lub qhov cub reflow thiab cov pa tawm ntawm tes.Thaum lub raj xa dej ua haujlwm, lub plhaub yog siv los txiav txim qhov kub thiab txias.Yog tias koj hnov ​​​​qhov kub thaum koj kov nws nrog koj txhais tes lossis koj tsis txhob kov nws, nws txhais tau hais tias qhov kev ua haujlwm rwb thaiv tsev ntawm lub qhov cub tsis zoo thiab lub zog siv loj.Feem ntau, tib neeg txhais tes xav tias kub me ntsis (kwv yees li 50 degrees Celsius).

2. Hom cua sov: Cov cua sov tuaj yeem muab faib ua cov teeb hluav taws xob infrared thiab hloov lub teeb cua sov.

(1) Tubular rhaub: Nws muaj qhov zoo ntawm kev ua haujlwm kub, luv hluav taws xob wavelength thiab cov lus teb ceev ceev.Txawm li cas los xij, vim yog lub cim ntawm lub teeb thaum cua sov, nws muaj qhov sib txawv ntawm qhov cuam tshuam ntawm vuam cov khoom sib txawv ntawm cov xim sib txawv.Nyob rau tib lub sijhawm, nws tsis yog nws tsim nyog rau kev sib txuam nrog cua kub yuam.

(2) Phaj rhaub: Lub thermal teb qeeb thiab qhov ua tau zoo me ntsis.Txawm li cas los xij, vim qhov loj thermal inertia, lub perforation yog conducive rau cov cua kub cua kub.Nws tsis tshua nkag siab rau cov xim ntawm cov khoom siv welded thiab muaj cov duab ntxoov ntxoo me me.Tsis tas li ntawd, tam sim no muag Nyob rau hauv reflow ncu, lub rhaub yog yuav luag tag nrho cov txhuas phaj los yog stainless hlau heaters.

3. Lub tshuab hluav taws xob hloov hluav taws xob ntawm reflow soldering yuav tsum muaj 4 mus rau 5 thaj chaw cua sov.

Zoo reflow soldering muaj tsawg kawg yog ib lub rhaub nyob rau hauv lub preheating cheeb tsam, thiab muaj peev xwm ntawm nws tus kheej tswj qhov kub thiab txias los xyuas kom meej tias qhov kub thiab txias yuav kis tau sai sai mus rau lub soldering kub nyob rau hauv peb txoj kev: conduction, convection, thiab hluav taws xob.

Cov ntsiab lus saum toj no yog hais txog yuav ua li cas reflow soldering.Thaum peb xaiv reflow soldering, peb tuaj yeem sib piv raws li cov ntsiab lus saum toj no.Nyob rau tib lub sijhawm, peb kuj yuav tsum xaiv hom reflow soldering raws li peb tus kheej xav tau.Kuv vam tias nws yuav pab tau sawv daws.
