Qhov zoo ntawm reflux nkhaus yuav tsum yog qhov kub thiab txias uas tuaj yeem ua tiav cov vuam zoo ntawm ntau qhov chaw mounting ntawm PCB pawg thawj coj saib yuav tsum tau welded, thiab cov sib koom ua ke tsis yog tsuas yog muaj qhov zoo nkauj zoo tab sis kuj zoo sab hauv.Yuav kom ua tiav qhov zoo ntawm cov hlau lead-dawb reflow kub nkhaus, muaj qee qhov kev sib raug zoo nrog txhua cov txheej txheem tsim tawm ntawm cov hlau lead-dawb reflow.Hauv qab no, Chengyuan Automation yuav tham txog cov laj thawj rau kev vuam tsis zoo los yog ntub dej ntawm cov hlau lead-dawb reflow me ntsis.
Nyob rau hauv cov txheej txheem tsis muaj hlau lead-dawb reflow vuam, nws yog ib qho tseem ceeb sib txawv ntawm qhov dull luster ntawm cov hlau lead-dawb reflow solder pob qij txha thiab qhov tshwm sim npub tshwm sim los ntawm qhov tsis tiav melting ntawm solder paste.Thaum lub rooj tsavxwm coated nrog solder paste dhau los ntawm lub cub tawg ntawm cov roj kub kub, yog tias qhov kub siab tshaj plaws ntawm cov tshuaj nplaum tsis tuaj yeem ncav cuag lossis lub sijhawm reflux tsis txaus, cov haujlwm ntawm cov flux yuav tsis raug tso tawm, thiab cov oxides thiab Lwm yam khoom nyob rau saum npoo ntawm cov ntaub so ntswg thiab cov tshuaj tiv thaiv tus pin tsis tuaj yeem ua kom huv, ua rau cov dej tsis zoo thaum lub sij hawm tsis muaj hlau lead-dawb reflow vuam.
Qhov teeb meem loj dua yog vim qhov ntsuas kub tsis txaus, qhov vuam kub ntawm cov khoom siv hlau nplaum rau ntawm qhov chaw ntawm lub rooj tsavxwm tsis tuaj yeem ncav cuag qhov kub thiab txias uas yuav tsum tau ua tiav rau cov hlau solder nyob rau hauv lub solder paste mus rau theem hloov, uas. ua rau qhov txias welding tshwm sim ntawm cov hlau lead-dawb reflow vuam qhov chaw.Los yog vim tias qhov kub tsis txaus, qee qhov seem ntawm cov kua nplaum nyob hauv cov tshuaj nplaum tsis tuaj yeem hloov pauv, thiab nws tuaj yeem ua rau hauv qhov sib koom ua ke thaum nws txias, ua rau lub ntsej muag dull ntawm cov khoom sib txuas.Ntawm qhov tod tes, vim tias cov khoom tsis zoo ntawm cov khoom siv hlau nplaum nws tus kheej, txawm tias lwm yam xwm txheej tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm qhov ntsuas kub ntawm cov hlau lead-dawb reflow vuam, cov khoom siv thiab cov tsos ntawm cov sib koom ua ke tom qab vuam tsis tuaj yeem ua tau raws li qhov xav tau. cov kev xav tau ntawm cov txheej txheem vuam.
