SMT ua nyob rau hauv kev ua tau zoo ntawm ntau yam, qhov zoo ntawm solder paste printing yog ib qho ntawm lawv, niaj hnub no SMT ua manufactory nyob rau hauv lubstencil tshuab luam ntawvyog siv nyob rau hauv tsis siv neeg solder paste tshuab luam ntawv kom tiav. Ntawm no yog ib qho kev qhia luv luv rau qee cov ntsiab lus ntawm solder paste luam ntawv.
I. Lub kaum sab xis
Squeegee lub kaum sab xis yog me dua, lub zog siv rau hauv cov tshuaj pleev xim rau hauv qab kuj loj dua, tab sis kuj tsis tshua yooj yim los txhuam cov stencil nto ntawm cov tshuaj txhuam. Yog tias lub kaum sab xis loj dhau lawm, cov nyhuv filling ntawm solder paste kuj yuav tsis zoo.
Pom zoo scraper lub kaum sab xis ntawm 45 degree ~ 75 degree (feem ntau tsau ntawm 60 degree los yog tag nrho tsis siv neeg tshuab).
II. Scraper ceev
SMT thaj ua rau solder paste luam ntawv squeegee ceev ntawm solder paste nraaj cuam tshuam yog complex. Feem ntau, qhov ceev ntawm 100mm / s ua ntej lub sij hawm filling plays lub luag hauj lwm tseem ceeb. Tom qab 100mm / s, solder paste viscosity plays lub luag haujlwm tseem ceeb. Txawm li cas los xij, ib yam yog qhov tshwm sim, uas yog, qhov nrawm nrawm dhau (siab dua 180mm / s) lossis qeeb dhau (qis dua 20mm / s), tsis zoo rau kev ntim cov tshuaj nplaum.
Pom zoo ntau yam ntawm squeegee ceev
Kev teeb tsa ntawm cov khoom siv suab nrov ntawm lub rooj tsavxwm: 140 ~ 160mm / s
Kev teeb tsa ntawm cov khoom zoo ntawm lub rooj tsavxwm: 25 ~ 60mm / s
III. Squeegee siab
Squeegee siab kuj yog ib qho tseem ceeb parameter nyob rau hauv cov txheej txheem ntawm SMT ua solder paste luam ntawv, thiaj li yuav ua tau raws li hauv qab ntawm lub stencil thiab PCB gapless kev sib cuag, qhov chaw ntawm lub solder paste scraped huv si nyob rau hauv lub premise uas lub solder paste yuav tsum tau tag nrho. thiab tuaj yeem raug khawb kom huv si raws li qhov xwm txheej ntawm qhov squeegee siab qhov me dua qhov zoo dua, kev siab ntau dhau tuaj yeem ua rau nruab nrab ntawm qhov loj-loj pad duab yog khawb. Squeegee siab feem ntau yog raws li qhov pib qhov chaw ntawm 0.5kg / 1 "thiab tom qab ntawd kho raws li cov duab kos.
IV. Qhov ceev ntawm descreening
Feem ntau, qhov ceev ntawm descreening, yooj yim tshwm sim ntawm lub qhov phab ntsa residual solder paste, uas ua rau tsawg tin los yog rub lub ntsis ntawm qhov tshwm sim. Yog tias qhov nrawm nrawm dhau, nws kuj yuav ua rau lub stencil rov qab.
