Cov hlau lead-dawb reflow soldering kub yog ntau dua li cov hlau lead-raws li reflow soldering kub.Qhov kub thiab txias ntawm cov hlau lead-dawb reflow soldering kuj nyuaj rau kho.Tshwj xeeb tshaj yog vim cov hlau lead-dawb soldering reflow txheej txheem qhov rais me me, kev tswj ntawm qhov sib txawv ntawm qhov kub thiab txias yog qhov tseem ceeb heev.Qhov loj ntawm qhov sib txawv ntawm qhov sib txawv hauv reflow soldering yuav ua rau cov khoom tsis xws luag.Yog li cas peb tuaj yeem txo qhov kub ntawm qhov sib txawv hauv reflow soldering kom ua tiav qhov zoo tshaj plaws txhuas tsis muaj reflow soldering nyhuv?Chengyuan Automation pib los ntawm plaub yam uas cuam tshuam rau reflow soldering nyhuv.
1. Cov cua kub hloov mus rau hauv cov hlau lead-dawb reflow soldering rauv
Tam sim no, lub ntsiab tseem ceeb ntawm cov hlau lead-dawb reflow soldering txais cov cua kub cua kub cua sov txoj kev.Nyob rau hauv txoj kev loj hlob ntawm reflow soldering qhov cub, infrared cua sov kuj tau tshwm sim.Txawm li cas los xij, vim muaj cua sov infrared, qhov nqus infrared thiab qhov cuam tshuam ntawm cov xim sib txawv ntawm cov khoom sib txawv thiab vim yog cov khoom qub uas nyob ib puag ncig Cov cuab yeej raug thaiv thiab ua rau cov duab ntxoov ntxoo, thiab ob qho xwm txheej yuav ua rau kub sib txawv thiab muab cov hlau lead ua rau muaj kev pheej hmoo dhia tawm. ntawm lub qhov rais txheej txheem.Yog li ntawd, infrared cua sov tshuab tau maj mam tshem tawm hauv cov txheej txheem cua sov ntawm reflow soldering ncu.Nyob rau hauv cov hlau lead-dawb soldering, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau lub tshav kub hloov pauv, tshwj xeeb tshaj yog rau cov khoom qub uas muaj peev xwm loj.Yog tias tsis tuaj yeem hloov pauv cov cua sov txaus, qhov ntsuas kub nce siab yuav ua rau poob qis tom qab cov khoom siv hluav taws xob me me, uas ua rau qhov sib txawv ntawm qhov kub thiab txias.Piv nrog rau kev siv cov cua kub tag nrho cov hlau lead-dawb reflow qhov cub, qhov kub ntawm qhov sib txawv ntawm cov hlau lead-dawb reflow soldering yuav raug txo.
2. Chain ceev tswj ntawm cov hlau lead-dawb reflow qhov cub
Lead-free reflow soldering saw ceev tswj yuav cuam tshuam qhov kub ntawm qhov sib txawv ntawm lub rooj tsav xwm Circuit Court.Feem ntau hais lus, txo cov saw nrawm yuav muab cov khoom siv nrog lub peev xwm loj kub ntau lub sijhawm kom sov, yog li txo qhov kub ntawm qhov sib txawv.Tab sis tom qab tag nrho, qhov kev teeb tsa ntawm lub cub tawg kub yog nyob ntawm qhov yuav tsum tau ntawm cov tshuaj txhuam hniav, yog li kev txo qis qis qis yog qhov tsis muaj tseeb hauv kev tsim khoom tiag tiag.Qhov no yog nyob ntawm kev siv cov tshuaj txhuam hniav.Yog hais tias muaj ntau yam kub-absorbing Cheebtsam nyob rau hauv lub Circuit Court board, rau cov khoom, nws raug nquahu kom txo cov reflow tsheb thauj mus los ceev ceev kom cov chips loj tuaj yeem nqus cov cua sov.
3. Tswj cua ceev thiab huab cua ntim hauv qhov cub tsis muaj hmoov lead
Yog tias koj khaws lwm yam kev mob hauv lub qhov cub uas tsis muaj txhuas tsis hloov pauv thiab tsuas yog txo cov kiv cua ceev hauv qhov cub tsis muaj hlau lead los ntawm 30%, qhov kub ntawm lub rooj tsav xwm Circuit Court yuav poob li ntawm 10 degrees.Nws tuaj yeem pom tau tias kev tswj cua ceev thiab huab cua ntim yog qhov tseem ceeb rau kev tswj qhov kub thiab txias.Yuav kom tswj tau qhov cua ceev thiab huab cua ntim, ob lub ntsiab lus yuav tsum tau them sai sai rau, uas tuaj yeem txo qhov kub ntawm qhov sib txawv ntawm cov hlau lead-dawb reflow rauv thiab txhim kho cov nyhuv soldering:
⑴ Cov kiv cua ceev yuav tsum tau tswj los ntawm kev hloov pauv zaus kom txo tau qhov cuam tshuam ntawm qhov hloov pauv ntawm qhov hluav taws xob ntawm nws;
⑵ Txo qhov tso pa tawm ntawm cov khoom siv kom ntau li ntau tau, vim tias qhov nruab nrab ntawm cov pa cua feem ntau tsis ruaj khov thiab tuaj yeem cuam tshuam cov cua kub hauv qhov cub.
4. Lead-free reflow soldering muaj kev ruaj ntseg zoo thiab tuaj yeem txo qhov kub qhov sib txawv hauv qhov cub.
Txawm hais tias peb tau txais qhov zoo tshaj plaws txhuas-dawb reflow qhov cub kub qhov profile, ua tiav nws tseem yuav tsum muaj kev ruaj ntseg, rov ua dua thiab sib xws ntawm cov hlau lead-dawb reflow soldering los xyuas kom meej nws.Tshwj xeeb tshaj yog nyob rau hauv cov hlau lead ntau lawm, yog hais tias muaj ib tug me ntsis drift vim cov khoom yog vim li cas, nws yog ib qho yooj yim mus dhia tawm ntawm lub qhov rais txheej txheem thiab ua rau txias soldering los yog thawj ntaus ntawv puas.Yog li ntawd, ntau thiab ntau manufacturers pib xav kom muaj kev ruaj ntseg kuaj cov cuab yeej.
