PCB Tus Qauv Qauv
1. PCB Hierarchical qauv tsim
Thawj kauj ruam hauv PCB tus qauv tsim yog los txiav txim rau PCB Hierarchy. Lub hierarchical qauv ntawm PCB muaj ob qho tseem ceeb: tus naj npawb ntawm cov khaubncaws sab nraud povtseg thiab cov qauv sib txuas ntawm txhua txheej. Rau cov ntawv thov hluav taws xob feem ntau, ob sab ib sab thiabPlaub Txheej Txheej yog cov feem ntau. Ob lub vaj huam sib luag panels yuav tsum muaj kev cuam tshuam thiab kev sib txuas ntawm tus saib xyuas ntawm txhua txheej txheej txheem ntawm ob txheej sib txuas ntawm ob sab hauv cov khaubncaws sab nraud thiab ob txheej.
2. Txiav txim siab PCB loj thiab cov duab
Kev txiav txim siab PCB loj thiab cov qauv yog lwm qhov tseem ceeb ntawm kev tsim qauv PCB. Qhov loj thiab cov duab ncaj qha cuam tshuam rau cov txiaj ntsig thiab kev ntseeg tau ntawm Circuit Courruit Board. Qhov loj thiab cov duab ntawm PCB yuav tsum txiav txim siab raws li cov cai thov. Nyob rau hauv kev ua lag luam hluav taws xob ntxiv, ntxiv ib qho chaw nyob rau thaj chaw PCB raws li cov cai yuav tsum tau ua yog ib qho kev coj ua.
3. Txiav txim siab cov khoom ntawm PCB
Cov ntaub ntawv kuj tseem ceeb ntawm kev tsim qauv PCB. Rau ob tog xib huam sib npaug, FR4 yog cov khoom siv uas feem ntau siv. Rau plaub txheej board thiab multi-txheej board, Pvb cov khoom siv tau siv, FR4 cov khoom yog xaiv rau txheej txheej pcb yuav tsum txhawb nqa los ntawm kua nplaum lossis rivets.
4. PCB xaim
Cov kev khiav haujlwm ntawm lub Circuit Court yog qhov tseem ceeb ntawm tus qauv PCB. Nws yog cov txheej txheem ntawm kev txuas cov hluav taws xob hauv hluav taws xob mus rau ib lub Circuit Court Board. Cov hlua hluav taws xob ua kom muaj kev ua yeeb yam hluav taws xob, tiv tauj Impedance, thiab muaj kev sib kis kom raug ntawm Circuit Court Board. Kev thwj thiab raug cov xaim hluav taws xob tsis tuaj yeem tsuas yog zam qhov tsis tsim nyog, tab sis kuj tseem ua kom cov ntshuam thiab kev ruaj ntseg ntawm cov khoom.
5. PCB Txheej Tshaj Tawm
Qhov txheej txuas ntawm PCB feem ntau kaw, thiab muaj kev nyab xeeb nyob deb yuav tsum tau tswj kom ntau li ntau tau thaum tsim teeb meem kev ntseeg tau. Cov kev ncua deb feem ntau yog suav nrog cov neeg nyob ib puag ncig thaum tswj cov kab thaiv, yam tsawg kawg nkaus muaj chaw nyab xeeb, thiab cuam tshuam los ntawm suab nrov.
6. PCB cov khoom sib ntxiv
Ntxiv rau cov kev cai pcb tsoos, PCBs tseem yuav tsum txiav txim siab ntxiv cov khoom sib txawv thiab cov ntsiab lus los xyuas kom zoo thiab ua tau zoo ntawm Circuit Court Board. Piv txwv li, PCBbs ntxiv cov khoom sib txuas xws li cov dig muag qhov, pins, pins, thiab txawm coj cov khoom lag luam txhim kho thiab muaj kev ntseeg tau.
7. PCB Soj Ntsuam
Hauv PCB qauv qauv tsim kev pab cuam yog lub kauj ruam kawg yog qhov system kuaj xyuas kom tshem tawm cov kev ua yuam kev thiab xyuas kom muaj kev ncaj ncees ntawm tus tsim. Thaum lub sij hawm kuaj tshuaj xyuas, tshuaj xyuas txhua txoj cai, qhov ntev, thiab txuas rau hauv cov qauv tsim yog qhov tseeb, thiab tseem ua tib zoo mloog rau qee qhov yuam kev.
