Kuv ntseeg tias ntau tus neeg tsis paub txog PCB Circuit Board, thiab tej zaum yuav hnov ntau zaus hauv lub neej txhua hnub, tab sis lawv yuav tsis paub ntau txog PCBA, thiab tej zaum yuav tsis meej pem nrog PCB.Yog li dab tsi yog PCB?PCBA hloov zuj zus li cas?Qhov txawv ntawm PCB thiab PCBA yog dab tsi?Cia wb mus saib ntxiv.
Txog PCB
PCB yog lub npe luv ntawm Printed Circuit Board, txhais ua lus Suav yog hu ua cov ntawv luam tawm Circuit Board, vim nws yog tsim los ntawm hluav taws xob luam ntawv, nws yog hu ua "printed circuit board".PCB yog cov khoom siv hluav taws xob tseem ceeb hauv kev lag luam hluav taws xob, kev txhawb nqa rau cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob sib txuas ntawm cov khoom siv hluav taws xob.PCB tau siv dav hauv kev tsim cov khoom siv hluav taws xob.Cov yam ntxwv tshwj xeeb ntawm PCB tau sau tseg raws li hauv qab no:
1. Cov kab hluav taws xob siab, qhov me me thiab lub teeb yuag, uas yog qhov tsim nyog rau cov khoom siv hluav taws xob miniaturization.
2. Vim yog qhov rov ua tau zoo thiab sib xws ntawm cov duab kos, qhov yuam kev hauv kev xaim thiab kev sib dhos raug txo, thiab cov khoom siv tu, kev debugging thiab tshuaj xyuas lub sijhawm raug cawm.
3. Nws yog qhov tsim nyog rau kev siv tshuab thiab tsis siv neeg ntau lawm, uas txhim kho kev ua haujlwm ntawm kev ua haujlwm thiab txo cov nqi ntawm cov khoom siv hluav taws xob.
4. Cov qauv tsim tuaj yeem ua tus qauv los pab txhawb kev sib hloov.
TxogPCBA
PCBA yog cov ntawv luv ntawm Printed Circuit Board + Sib dhos, uas txhais tau hais tias PCBA dhau los ntawm tag nrho cov txheej txheem tsim khoom ntawm PCB dawb paug board SMT thiab tom qab ntawd DIP plug-in.
Lus Cim: Ob qho SMT thiab DIP yog txoj hauv kev los koom ua ke ntawm PCB.Qhov sib txawv tseem ceeb yog SMT tsis tas yuav tho qhov ntawm PCB.Hauv DIP, tus PIN pins ntawm cov khoom yuav tsum tau muab tso rau hauv lub qhov drilled.
SMT (Nto Mounted Technology) nto mount thev naus laus zis feem ntau siv cov mounters rau mount qee qhov me me ntawm PCB.Cov txheej txheem ntau lawm yog: PCB board positioning, solder paste printing, mounter mounting, thiab reflow rauv thiab ua tiav kev soj ntsuam.
DIP txhais tau tias "plug-in", uas yog, ntxig qhov chaw ntawm lub rooj tsavxwm PCB.Qhov no yog kev koom ua ke ntawm cov khoom hauv daim ntawv ntawm plug-ins thaum qee qhov chaw loj dua thiab tsis haum rau kev tso kawm technology.Cov txheej txheem tseem ceeb yog: nplaum nplaum, ntsaws-hauv, tshuaj xyuas, yoj soldering, luam ntawv thiab tshuaj xyuas tiav.
* Qhov txawv ntawm PCB thiab PCBA *
Los ntawm cov lus qhia saum toj no, peb tuaj yeem paub tias PCBA feem ntau yog hais txog cov txheej txheem ua haujlwm, uas tuaj yeem nkag siab tias yog lub rooj tsav xwm ua tiav, uas txhais tau hais tias PCBA tsuas tuaj yeem suav tom qab cov txheej txheem ntawm PCB pawg thawj coj ua tiav.PCB yog hais txog lub rooj tsavxwm uas tsis muaj cov ntawv luam tawm uas tsis muaj qhov chaw ntawm nws.
Feem ntau hais lus: PCBA yog lub rooj tsavxwm tiav;PCB yog ib tug liab qab board.
