Thaum tsim cov khoom siv hluav taws xob lossis hluav taws xob, ib qho ntawm cov kev txiav txim siab tseem ceeb uas koj yuav ntsib yog xaiv hom ntawv luam tawm Circuit Board (PCB) siv.Ob txoj kev xaiv yog ob sab PCB thiab ib sab PCB.Txawm hais tias ob leeg muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, kev xaiv txoj cai tuaj yeem ua kom tiav qhov project tiav.Hauv qhov blog no, peb yuav ua tib zoo saib cov yam ntxwv ntawm ob sab PCBs thiab ib sab PCBs los pab koj txiav txim siab paub.
Ob chav sided PCB.
Ob tog PCBs muaj cov cim tooj liab thiab cov khoom ntawm ob sab ntawm lub rooj tsavxwm, sib txuas los ntawm vias lossis plated los ntawm qhov.Cov vias no ua raws li cov kab hluav taws xob sib txuas, tso cai rau cov teeb liab dhau los ntawm cov txheej txheem sib txawv ntawm PCB, ua rau nws ntau dua thiab ntau yam.Cov laug cam no feem ntau siv hauv cov khoom siv hluav taws xob nyuaj xws li smartphones, khoos phis tawj kho vajtse, thiab cov ntawv thov siab.
Qhov zoo ntawm ob sab PCB.
1. Kev tivthaiv ntau ntxiv: Ob tog PCBs tuaj yeem ua raws li cov khoom siv ntau dua, muab kev ua haujlwm siab dua hauv qhov loj me.Qhov no yog qhov tseem ceeb thaum tsim cov tshuab hluav taws xob complex.
2. Txhim khu kev xaim hluav taws xob: Nrog rau cov kab tooj liab ntawm ob sab ntawm lub rooj tsavxwm, cov neeg tsim qauv muaj ntau txoj kev xaiv, txo cov teeb liab cuam tshuam thiab sib tham sib.Qhov no txhim kho cov teeb liab kev ncaj ncees thiab kev ua haujlwm tag nrho.
3. Tus Nqi-Kev Ua Tau Zoo: Txawm hais tias nws qhov nyuaj, ob tog PCBs tau txais txiaj ntsig zoo vim lawv siv dav thiab muaj.Lawv tuaj yeem ua tau zoo ntawm cov nplai, ua rau lawv muaj peev xwm xaiv tau rau cov haujlwm loj.
Disadvantages ntawm ob sab PCB
1. Kev tsim qauv tsis yooj yim: Qhov nyuaj ntawm ob tog PCB ua rau cov txheej txheem tsim qauv nyuaj, xav tau cov software nyuaj thiab cov neeg tsim qauv paub txog.Qhov no ua rau tus nqi tsim kho tag nrho ntawm qhov project.
2. Soldering cov nyom: Txij li cov khoom muaj nyob rau ntawm ob sab, soldering tuaj yeem nyuaj dua, tshwj xeeb tshaj yog rau cov khoom siv thev naus laus zis (SMT).Kev saib xyuas ntxiv yog yuav tsum tau thaum lub sij hawm sib dhos kom tsis txhob muaj luv luv Circuit Court thiab tsis xws luag.
Ib sab PCB
Ntawm qhov tod tes, ib qho PCB ib leeg yog daim ntawv yooj yim tshaj plaws ntawm PCB, nrog cov khoom thiab cov kab tooj liab tam sim no ntawm ib sab ntawm lub rooj tsavxwm.Cov hom PCBs no feem ntau yog siv rau hauv cov ntawv siv tsawg dua xws li cov khoom ua si, lub tshuab xam zauv, thiab cov khoom siv hluav taws xob tsawg.
Qhov zoo ntawm ib sab PCB
1. Yooj yim rau kev tsim: Piv nrog ob-sided PCB, ib leeg-sided PCB kuj yooj yim rau kev tsim.Lub simplicity ntawm qhov layout speeds prototyping thiab txo lub sij hawm tsim.
2. Txo cov nqi tsim kho: PCBs ib leeg yog tus nqi tsim nyog nrog tsawg dua cov txheej tooj liab thiab cov qauv yooj yim, ua rau lawv zoo tagnrho rau cov phiaj xwm nyiaj txiag tsawg lossis cov haujlwm uas muaj kev txwv tsis pub siv.
3. Cov txheej txheem vuam yooj yim dua: Tag nrho cov khoom siv nyob rau ntawm ib sab, vuam ua yooj yim dua, haum rau DIY enthusiasts thiab amateurs.Tsis tas li ntawd, qhov kev txo qis hauv kev nyuaj yooj yim rau kev daws teeb meem.
Disadvantages ntawm ib sab PCB
1. Kev txwv qhov chaw: Ib qho kev txwv tseem ceeb ntawm PCBs ib leeg yog qhov txwv tsis pub muaj rau cov khoom siv thiab kev ua haujlwm.Qhov no txwv lawv txoj kev siv nyob rau hauv cov txheej txheem nyuaj uas yuav tsum muaj kev ua haujlwm siab dhau los lossis txuas txuas ntxiv.
2. Cov teeb liab cuam tshuam: Ib leeg-sab PCB tsis muaj kev ywj pheej ntawm lub zog hluav taws xob thiab txheej hauv av, uas yuav ua rau muaj teeb meem cuam tshuam thiab lub suab nrov, cuam tshuam rau kev ua haujlwm thiab kev ntseeg siab ntawm Circuit Court.
Qhov kev xaiv ntawm ob-sided PCB thiab ib leeg-sided PCB nyob ntawm qhov nyuaj thiab cov kev xav tau ntawm cov khoom siv hluav taws xob.PCBs ib leeg yog tsim rau cov ntawv yooj yim nrog kev ua haujlwm tsawg, thaum ob tog PCBs muab kev yooj yim dua, cov khoom siv ntau dua thiab txhim kho kev muaj peev xwm rau ntau lub tshuab.Xav txog yam xws li tus nqi, qhov xav tau ntawm qhov chaw, thiab tag nrho cov phiaj xwm phiaj xwm los txiav txim siab qhov tsim nyog tshaj plaws PCB hom.Nco ntsoov, kev tshawb fawb kom raug, kev npaj, thiab kev sab laj nrog tus kws tshaj lij PCB tsim yog qhov tseem ceeb rau kev ua tiav ntawm koj qhov project.
