Lub PCB board (Printedcircuitboard) yog lub cev txhawb nqa ntawm cov khoom siv hluav taws xob thiab yog tus muab kev sib txuas ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Nws yuav luag yog lub hauv paus ntawm txhua yam khoom siv ntse. Ntxiv rau cov haujlwm tseem ceeb ntawm kev kho ntau yam khoom siv hluav taws xob me me, qhov tseem ceeb tshaj plaws yog muab kev sib txuas ntawm cov khoom siv hluav taws xob saum toj no.
Cov khoom ntawm PCB board yog dab tsi?
Lub PCB Circuit Board feem ntau yog tsim los ntawm vuam pad, los ntawm qhov, mounting qhov, hlau, Cheebtsam, connectors, filling, hluav taws xob ciam teb thiab lwm yam.
(1) Pad: qhov hlau siv rau vuam cov pins ntawm cov khoom.
(2) Los ntawm qhov: muaj hlau los ntawm qhov thiab tsis yog hlau los ntawm qhov, qhov twg cov hlau los ntawm qhov yog siv los txuas cov pins ntawm cov khoom ntawm txhua txheej.
(3) Qhov Mounting: siv los kho lub rooj tsavxwm Circuit Court.
(4) Tus neeg xyuas pib: zaj duab xis tooj liab siv los txuas cov pins ntawm cov khoom.
(5) Cov khoom sib txuas: cov khoom siv rau kev txuas cov laug cam.
(6) Kev sau: daim ntawv thov tooj liab rau hauv av xaim network tuaj yeem txo qhov impedance.
(7) Ciam teb hluav taws xob: siv los txiav txim siab qhov loj ntawm lub rooj tsavxwm, cov khoom ntawm lub rooj tsavxwm tsis tuaj yeem tshaj qhov ciam teb.
Raws li cov qauv ntawm PCB, nws muaj peev xwm muab faib ua ib lub PCB, ob lub PCB, thiab ntau txheej PCB; feem ntau, plaub txheej yog rau txheej, thiab ntau txheej PCB tuaj yeem ncav cuag ntau tshaj kaum txheej.
Cov txheej ntawm PCB boards ntau dua, qhov ruaj khov thiab txhim khu kev qha ntawm kev ua haujlwm hluav taws xob, thiab tus nqi siab dua. Qhov sib txawv ntawm tus nqi ntawm ib lub vaj huam sib luag thiab ob lub vaj huam sib luag tsis loj. Yog tias tsis muaj qhov xav tau tshwj xeeb, txhua lub lag luam yuav xaiv ob lub vaj huam sib luag. Tom qab tag nrho, qhov kev ua tau zoo thiab kev ruaj khov ntawm ob lub vaj huam sib luag zoo dua li ntawm ib lub vaj huam sib luag.
Hauv PCB multilayer board, tam sim no kev lag luam yog qhov siv ntau tshaj plaws lossis plaub, rau txheej board, kev lag luam khoom siv hluav taws xob nrog cov pcb board siab dua yog ntau dua. Txawm hais tias multilayer panels muaj ntau qhov zoo dua li dual panels hauv kev ua tau zoo, kev ruaj khov, suab nrov thiab lwm yam, ntau lub tuam txhab thiab cov engineers tseem nyiam dual panels rau kev txiav txim siab tus nqi.
Thaum cov khoom siv ntse ua ntau zuj zus, xav tau ntau yam khoom siv ntxiv, uas ua rau muaj ntau lub voj voog me me thiab cov khoom siv ntxiv rau ntawm PCB. Tib lub sijhawm, qhov yuav tsum tau ua kom zoo ntawm cov khoom siv hluav taws xob siab tam sim no ntawm PCB kuj tau txhim kho. Lub rooj tsavxwm PCB me me tsis tsuas yog txo tus nqi xwb, tab sis kuj tuaj yeem ua kom yooj yim rau kev tsim qauv ntawm PCB board, yog li ntawd qhov poob ntawm lub voj voog kis tau me dua.
Cov khoom siv sib sau ua ke ntawm cov khoom siv hluav taws xob siab PCB tsuas yog qhov loj me ntawm lub pob qij txha xwb, thiab tus neeg xyuas pib yog nyiaj plated nrog tooj liab, uas ua rau lub connector muaj zog dua. Txawm tias qhov me me kuj tuaj yeem muaj zog dua, ua kom lub voj voog khiav zoo, thiab ntau txoj kev teeb tsa tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv ntawm PCB board.
Amass muaj cov qhov ntev sib txawv ntawm cov khoom sib txuas rau PCB circuit boards ntawm ntau qhov tuab sib txawv, uas ua raws li tus qauv kev lag luam ntawm cov vaj huam sib luag tuab ntawm 1.0-1.6 hli kom ntseeg tau tias siv cov khoom siv ib txwm muaj!
