Hauv cov khoom siv hluav taws xob, tsim lub rooj tsav xwm luam tawm (PCB) yog ib kauj ruam tseem ceeb hauv kev ua kom muaj kev ua haujlwm raug thiab ua haujlwm zoo.OrCAD yog qhov nrov hluav taws xob tsim hluav taws xob automation (EDA) software uas muab cov cuab yeej muaj zog los pab cov engineers hauv seamlessly converting schematics rau PCB layouts.Hauv tsab xov xwm no, peb yuav tshawb xyuas cov lus qhia ib kauj ruam ntawm yuav ua li cas hloov lub schematic rau PCB layout siv OrCAD.
Kauj ruam 1: Tsim ib qhov project tshiab
Ua ntej delving rau hauv PCB layout, nws yog ib qho tsim nyog los teeb tsa ib txoj haujlwm tshiab hauv OrCAD kom npaj koj cov ntaub ntawv tsim tau zoo.Ua ntej pib OrCAD thiab xaiv New Project los ntawm cov ntawv qhia zaub mov.Xaiv ib qhov project npe thiab qhov chaw nyob ntawm koj lub computer, ces nias OK mus ntxiv.
Kauj ruam 2: Ntshuam lub Schematic
Cov kauj ruam tom ntej yog import cov schematic rau hauv OrCAD software.Txhawm rau ua qhov no, mus rau "Cov Ntaub Ntawv" ntawv qhia zaub mov thiab xaiv "Ntshuam".Xaiv cov hom ntawv schematic uas tsim nyog (piv txwv li, .dsn, .sch) thiab mus rau qhov chaw uas cov ntaub ntawv schematic raug cawm.Thaum xaiv, nyem Ntshuam mus thauj cov schematic rau hauv OrCAD.
Kauj Ruam 3: Tshawb xyuas Tsim
Ua kom ntseeg tau qhov tseeb thiab kev ua haujlwm ntawm schematic yog ib qho tseem ceeb ua ntej pib nrog PCB layout.Siv OrCAD cov cuab yeej built-in xws li Design Rule Checking (DRC) txhawm rau txheeb xyuas cov kev ua yuam kev lossis tsis sib xws hauv koj tus qauv tsim.Hais txog cov teeb meem no nyob rau theem no yuav txuag lub sijhawm thiab kev siv zog thaum lub sijhawm txheej txheem PCB.
Kauj Ruam 4: Tsim cov txheej txheem PCB Board
Tam sim no hais tias cov schematic tau raug txheeb xyuas, cov kauj ruam tom ntej yog los tsim cov txheej txheem PCB tiag tiag.Hauv OrCAD, mus rau qhov chaw qhia zaub mov thiab xaiv Board Outline.Siv cov cuab yeej no los txhais cov duab thiab qhov loj ntawm koj lub PCB raws li koj xav tau.Xyuas kom meej tias lub rooj tsavxwm txheej txheem ua raws li cov qauv tsim tshwj xeeb thiab kev txwv tsis pub siv tshuab (yog tias muaj).
Kauj Ruam 5: Muab Cov Cheeb Tsam
Cov theem tom ntej yog muab cov khoom sib xyaw rau hauv PCB layout.Siv OrCAD cov cuab yeej muab tso rau hauv cov cuab yeej los rub thiab tso cov khoom tsim nyog los ntawm lub tsev qiv ntawv mus rau PCB.Nco ntsoov muab cov khoom tso rau hauv txoj hauv kev uas txhim kho cov teeb liab ntws, txo qis suab nrov, thiab ua raws li DRC cov lus qhia.Ua tib zoo saib xyuas cov khoom taw qhia, tshwj xeeb tshaj yog polarizing Cheebtsam.
Kauj ruam 6: Routing Connections
Tom qab muab cov khoom sib xyaw, cov kauj ruam tom ntej yog los ntawm kev sib txuas ntawm lawv.OrCAD muab cov cuab yeej siv hluav taws xob muaj zog los pab txoj kev xaim hluav taws xob kom muaj kev sib txuas hluav taws xob.Nco ntsoov cov xwm txheej xws li teeb liab kev ncaj ncees, qhov sib txuam ntev, thiab tsis txhob hla kev hla thaum routing.OrCAD's autorouting feature ua kom yooj yim rau cov txheej txheem no, txawm hais tias phau ntawv routing raug pom zoo rau ntau cov qauv tsim.
Kauj Ruam 7: Tsim Txoj Cai Txheeb Xyuas (DRC)
Ua ntej ua tiav cov txheej txheem PCB, nws yog ib qho tseem ceeb uas yuav tsum tau ua qhov kev kuaj xyuas kev tsim qauv (DRC) kom ntseeg tau tias kev ua raws li cov kev txwv tsim khoom.OrCAD's DRC feature cia li kuaj pom qhov tsis raug cuam tshuam nrog qhov sib txawv, kev tshem tawm, lub npog ntsej muag, thiab lwm yam kev cai tsim.Kho txhua qhov teeb meem uas tau teev tseg los ntawm DRC cov cuab yeej los xyuas kom meej tias PCB tsim yog tsim tau.
Kauj Ruam 8: Tsim cov ntaub ntawv tsim khoom
Thaum cov txheej txheem PCB tsis muaj qhov yuam kev, cov ntaub ntawv tsim khoom xav tau rau PCB fabrication tuaj yeem tsim tawm.OrCAD muab txoj hauv kev yooj yim los tsim cov qauv kev lag luam Gerber cov ntaub ntawv, Bill of Materials (BOM) thiab lwm yam khoom tsim nyog.Cov ntaub ntawv tsim tawm tau raug lees paub thiab sib koom nrog cov tuam txhab tsim khoom txuas ntxiv PCB.
Hloov schematics rau PCB layouts siv OrCAD koom nrog cov txheej txheem uas ua kom paub tseeb tus qauv tsim, kev ua haujlwm, thiab kev tsim khoom.Los ntawm kev ua raws li cov lus qhia ib kauj ruam dhau los no, engineers thiab hobbyists tuaj yeem siv lub zog ntawm OrCAD kom coj lawv cov qauv siv hluav taws xob mus rau lub neej.Kev paub txog kev kos duab ntawm kev hloov pauv ntawm schematic rau PCB layout yuav ua rau koj lub peev xwm los tsim cov qauv siv hluav taws xob zoo tshaj plaws.
