Puas yog koj yog ib tus neeg nyiam siv hluav taws xob tab tom nrhiav dhia rau hauv lub ntiaj teb ntawm PCB tsim? Saib tsis ntxiv! Hauv phau ntawv qhia pib no, peb yuav tshawb xyuas cov kauj ruam yooj yim ntawm kev tsim PCB siv cov software nrov OrCAD. Txawm hais tias koj yog tub ntxhais kawm, hobbyist lossis cov kws tshaj lij, kev paub txog PCB tsim yuav qhib qhov rooj rau qhov tsis muaj qhov kawg. Yog li, cia peb pib.
1. Paub cov hauv paus ntsiab lus:
Ua ntej dhia mus rau hauv tus txheej txheem tsim, paub koj tus kheej nrog cov hauv paus ntawm PCBs. PCB yog cov ntawv luv ntawm cov ntawv luam tawm Circuit Board, uas yog ib feem tseem ceeb ntawm cov khoom siv hluav taws xob. Nws mechanically txhawb thiab hluav taws xob txuas ntau yam khoom siv hluav taws xob. Kev nkag siab zoo ntawm circuit schematics, Cheebtsam thiab lawv layout.
2. Xaiv OrCAD:
OrCAD los ntawm Cadence Design Systems yog cov cuab yeej software ua haujlwm dav siv rau PCB tsim. Nws muab tag nrho cov cuab yeej rau schematic capture, tivthaiv tso thiab routing. Rub tawm thiab nruab OrCAD software ntawm koj lub computer kom pib.
3. Schematic capture:
Pib koj txoj kev tsim qauv los ntawm kev tsim cov schematic nrog OrCAD Capture. Cov cuab yeej no tso cai rau koj los kos cov kev sib txuas hauv Circuit Court, ntxiv cov khoom thiab txhais lawv cov khoom hluav taws xob. Xyuas kom raug xaiv cov cim thiab kev sib txuas ntawm cov khoom ntawm tus kheej.
4. Cheebtsam muab tso rau:
Thaum cov schematic ua tiav, txav mus rau cov kauj ruam tom ntej: qhov chaw tso khoom. OrCAD PCB Designer muab cov cuab yeej rau kev tso cov khoom ntawm PCB layout. Xav txog yam xws li qhov sib thooj ntawm cov khoom sib thooj, cov teeb liab kev ncaj ncees, thiab qhov ua kom zoo tshaj qhov ntev thaum tso cov khoom. Kev tso tawm tswv yim ua kom muaj txiaj ntsig zoo thiab txo cov teeb liab cuam tshuam.
5. Routing:
Tam sim no yog qhov txuas tseem ceeb tshaj plaws hauv kev tsim PCB - theem routing. OrCAD lub peev xwm routing tso cai rau koj los tsim cov kab tooj liab uas txuas ntau yam ntawm PCB. Txoj kev tsim nyog ua kom muaj kev ncaj ncees ntawm cov teeb liab thiab txo cov suab nrov thiab cuam tshuam. Cov kev cai tsim xws li clearance spacing thiab trace thickness yuav tsum tau ua raws li los xyuas kom meej functionality.
6. Teeb liab kev ncaj ncees thiab DRC kos:
Siv OrCAD's built-in SI cov cuab yeej los ua lub teeb liab kev ncaj ncees (SI) cov tshev ua ntej ua tiav koj qhov tsim. Cov kev kuaj xyuas no txheeb xyuas cov teeb liab cuam tshuam lossis kev cuam tshuam uas tuaj yeem cuam tshuam kev ua haujlwm tag nrho. Tsis tas li ntawd, khiav txoj cai kuaj xyuas (DRC) kom ua tau raws li cov txheej txheem tsim khoom thiab kev txwv hluav taws xob.
7. Kev Tshawb Fawb Tsim:
Thaum tus qauv PCB tiav lawm, yuav tsum muaj txheej txheem pov thawj kom meej. Tshawb xyuas cov qauv tsim kom raug, suav nrog luv luv, qhib, lossis lwm yam teeb meem. Tshawb xyuas cov ntawv sau cov khoom kom raug, cov ntawv qhia meej, thiab sib xws ntawm cov khaubncaws sab nraud povtseg. Xyuas kom tseeb yog qhov tseem ceeb ua ntej mus rau kev tsim khoom.
8. Export thiab manufacture:
Thaum koj txaus siab rau tus tsim, xa tawm PCB layout mus rau tus qauv qauv xws li Gerber RS-274X. Hom ntawv no tau txais dav los ntawm PCB manufacturers. Tsim cov ntaub ntawv sib cais rau txhua txheej, suav nrog cov kab tooj liab, daim npog ntsej muag, thiab cov qhov drilled. Cov neeg tsim khoom yuav siv cov ntaub ntawv no los tsim lub cev PCB.
Tsim ib PCB nrog OrCAD tej zaum yuav zoo li daunting thaum xub thawj, tab sis nrog kev xyaum thiab kev ua siab ntev nws tuaj yeem dhau los ua qhov zoo siab thiab muaj txiaj ntsig zoo. Nco ntsoov pib nrog cov hauv paus, xaiv cov cuab yeej software tsim nyog, thiab ua raws li txoj hauv kev. PCB tsim yog cov txheej txheem kev kawm tas mus li, yog li tshawb nrhiav cov thev naus laus zis siab thaum tau txais kev paub. Yog li vim li cas tos? Unleash koj lub tswv yim thiab pib tsim koj tus kheej PCBs nrog OrCAD hnub no!
