PCBA yog tsim los txiav txim siab cov ntsiab lus tshwj xeeb ntawm thermal tsim
Qee qhov teeb meem yuav tsum tau them sai sai rau thaum tsim PCBA, xws li PCBA kev sib dhos txheej txheem tsim, cov qauv tsim qauv, kev sib dhos txheej txheem tsim, tsis siv neeg cov kab ntau lawm veneer kis tau tus mob thiab qhov chaw tsim khoom.
1. Tsis siv neeg ntau lawm kab board kis tau tus mob thiab positioning ntsiab tsim, tsis siv neeg ntau lawm kab sib dhos, PCB yuav tsum muaj peev xwm kis tau tus ntug thiab optical positioning cim, uas yog prerequisite rau ntau lawm.
2.PCBA sib dhos txheej txheem tsim, PCBA sib dhos txheej txheem tsim, uas yog, cov khoom nyob rau hauv pem hauv ntej thiab nram qab ntawm PCB Cheebtsam layout qauv. Nws txiav txim siab cov txheej txheem PCB cog txoj kev thiab txoj hauv kev rau kev sib dhos, yog li nws tseem hu ua txheej txheem kev tsim.
3. Cov qauv tsim qauv, uas yog, txoj hauj lwm, kev taw qhia thiab qhov sib txawv ntawm cov khoom ntawm cov khoom sib dhos. Cov txheej txheem ntawm cov khoom yog nyob ntawm txoj kev siv vuam siv. Txhua txoj kev vuam muaj cov kev cai tshwj xeeb ntawm qhov chaw tso kawm, kev taw qhia thiab qhov sib nrug ntawm cov khoom. Yog li ntawd, phau ntawv no qhia txog cov txheej txheem tsim qauv raws li cov txheej txheem vuam siv hauv ntim. Nws yuav tsum tau taw qhia tias qee zaum ob lossis ntau qhov txheej txheem vuam siv rau qhov chaw sib dhos, xws li" reflow welding 10 yoj vuam", rau cov xwm txheej zoo li no, PCBA layout yuav tsum tau tsim raws li vuam. txheej txheem siv rau txhua pob.
4. Kev sib dhos txheej txheem tsim, kev sib dhos txheej txheem tsim, tsim rau vuam rty (xws li, los ntawm vuam phaj, tsis kam vuam thiab kev sib txuam tsim ntawm stencil, solder paste kom muaj nuj nqis, kev ruaj ntseg ntawm qhov chaw ruaj khov, los ntawm kev tsim cov layout, kom ua tiav ib qho synchronous melting thiab solidification, encapsulate tag nrho cov welds los ntawm kev txhim kho lub qhov tsim nyog hlau tsim, ua tiav 75% tin nkag tus nqi, thiab lwm yam., Cov e tsim lub hom phiaj yog qhov kawg los txhim kho cov txiaj ntsig ntawm vuam.
Muaj ntau cov ntsiab lus ntawm PCBA thermal tsim, thiab cov kev cai tshwj xeeb ntawm txhua lub PCB cov ntsiab lus yuav muaj qee qhov sib txawv. Piv txwv li, yog tias muaj tsawg dua tin nyob rau hauv thermal tsim ntawm lub dab dej kub, peb tuaj yeem siv qee txoj kev los daws qhov teeb meem. Qhov feem ntau yog ua kom cov cua sov dissipation qhov. Yog li peb tsis' tsis tas yuav ntshai thaum peb ntsib qee qhov teeb meem, nrhiav qee tus neeg tshaj lij tuaj yeem daws tau tag nrho peb cov teeb meem.
(1) Thermal tsim ntawm lub dab dej kub. Nyob rau hauv lub vuam ntawm cov dab dej kub, tin poob ntawm lub dab dej kub yog ntsib, uas yog ib qho kev thov uas tuaj yeem txhim kho los ntawm kev tsim cov dab dej kub.
Rau qhov teeb meem saum toj no, chip Hoobkas tuaj yeem siv txoj hauv kev los nce lub peev xwm ntawm lub qhov cua txias los tsim. Txuas lub tshav kub dissipation qhov nrog cov txheej hauv av, yog tias cov txheej hauv av tsawg dua 6 txheej. Ib feem ntawm cov teeb liab txheej tuaj yeem raug cais tawm raws li cov txheej txheem kub dissipation thaum txo qhov aperture mus rau qhov tsawg kawg nkaus aperture loj.
(2) thermal tsim ntawm high-power grounding jack.
Hauv qee qhov kev tsim khoom tshwj xeeb, lub qhov ntsaws yog qee zaum yuav tsum tau txuas nrog ntau qhov chaw hauv av / qib. Vim hais tias lub sij hawm sib cuag ntawm tus pin thiab tin yoj yog luv heev, feem ntau rau 2 ~ 3s, yog hais tias lub tshav kub muaj peev xwm ntawm lub jack kuj loj, qhov kub ntawm cov hlau lead yuav tsis ua tau raws li qhov yuav tsum tau ntawm vuam, tsim txias - vuam point.
