momwe mungasinthire masanjidwe a schematic kukhala pcb mu orcad

Pazamagetsi, kupanga bolodi losindikizidwa (PCB) ndi gawo lofunikira pakuwonetsetsa kuti magwiridwe antchito ndi olondola.OrCAD ndi pulogalamu yotchuka ya electronic design automation (EDA) yomwe imapereka zida zamphamvu zothandizira mainjiniya pakusintha ma schematics kukhala masanjidwe a PCB.M'nkhaniyi, tiwona momwe mungasinthire masinthidwe kukhala mawonekedwe a PCB pogwiritsa ntchito OrCAD.

Gawo 1: Pangani pulojekiti yatsopano

Musanafufuze masanjidwe a PCB, ndikofunikira kukhazikitsa pulojekiti yatsopano ku OrCAD kuti mukonzekere bwino mafayilo anu opangira.Choyamba yambani OrCAD ndikusankha New Project kuchokera pamenyu.Sankhani dzina la polojekiti ndi malo pa kompyuta yanu, kenako dinani Chabwino kuti mupitirize.

Gawo 2: Lowetsani Schematic

Chotsatira ndikulowetsa schema mu pulogalamu ya OrCAD.Kuti muchite izi, pitani ku menyu "Fayilo" ndikusankha "Import".Sankhani mtundu woyenera wa fayilo (mwachitsanzo, .dsn, .sch) ndikuyenda kumalo komwe fayilo yokonzekera imasungidwa.Mukasankhidwa, dinani Import kuti mukweze schematic mu OrCAD.

Gawo 3: Tsimikizirani Mapangidwe

Kuwonetsetsa kulondola ndi magwiridwe antchito a schematic ndikofunikira musanapitirize ndi masanjidwe a PCB.Gwiritsani ntchito zida zomangidwira za OrCAD monga Design Rule Checking (DRC) kuti muwone zolakwika kapena zosagwirizana pamapangidwe anu.Kuthana ndi mavutowa panthawiyi kudzapulumutsa nthawi ndi khama panthawi ya ndondomeko ya PCB.

Gawo 4: Pangani PCB Board Outline

Tsopano popeza chilinganizo chatsimikiziridwa, sitepe yotsatira ndiyo kupanga ndondomeko yeniyeni ya bolodi ya PCB.Mu OrCAD, pita kumenyu yoyika ndikusankha Board Outline.Gwiritsani ntchito chida ichi kutanthauzira mawonekedwe ndi kukula kwa PCB yanu malinga ndi zomwe mukufuna.Onetsetsani kuti autilaini ya bolodi ikugwirizana ndi zopinga za kapangidwe kake ndi zopinga zamakina (ngati zilipo).

Khwerero 5: Kuyika Zida

Gawo lotsatira likuphatikiza kuyika zigawozo pamapangidwe a PCB.Gwiritsani ntchito zida zoyika za OrCAD kuti mukoke ndikugwetsa zofunikira kuchokera ku laibulale kupita pa PCB.Onetsetsani kuti mwayika zigawo m'njira yowongolerera kayendedwe ka ma siginecha, kuchepetsa phokoso, komanso kutsatira malangizo aku DRC.Samalani ku mbali ya zigawo, makamaka polarizing zigawo zikuluzikulu.

Khwerero 6: Njira zolumikizirana

Pambuyo poyika zigawozo, sitepe yotsatira ndiyo kuyendetsa kugwirizana pakati pawo.OrCAD imapereka zida zamphamvu zowongolera mawaya kuti azilumikiza magetsi.Kumbukirani zinthu monga kukhulupirika kwa siginecha, kufananiza kutalika, komanso kupewa kuwoloka poyenda.Mawonekedwe a autorouting a OrCAD amathandiziranso izi, ngakhale kuwongolera pamanja kumalimbikitsidwa pakupanga zovuta.

Khwerero 7: Chongani Malamulo Opangira (DRC)

Musanamalize masanjidwe a PCB, ndikofunikira kuti muyambe kuyang'ana malamulo apangidwe (DRC) kuti muwonetsetse kuti zikugwirizana ndi zovuta zopanga.Mbali ya OrCAD's DRC imangozindikira zolakwika zokhudzana ndi malo, chilolezo, chigoba cha solder, ndi malamulo ena opangira.Konzani nkhani zilizonse zomwe zidadziwika ndi chida cha DRC kuti muwonetsetse kuti mapangidwe a PCB ndi opangidwa.

Khwerero 8: Pangani Mafayilo Opanga

Kapangidwe ka PCB kakakhala kopanda cholakwika, mafayilo opangira ma PCB atha kupangidwa.OrCAD imapereka njira yosavuta yopangira mafayilo amtundu wa Gerber, Bill of Materials (BOM) ndi zina zofunika.Mafayilo opangidwa amatsimikiziridwa ndikugawidwa ndi opanga kuti apitilize kupanga PCB.

Kutembenuza schematics kukhala PCB masanjidwe pogwiritsa ntchito OrCAD kumaphatikizapo njira yadongosolo yomwe imatsimikizira kulondola kwa mapangidwe, magwiridwe antchito, ndi kupangidwa.Potsatira malangizowa pang'onopang'ono, mainjiniya ndi okonda masewerawa amatha kugwiritsa ntchito mphamvu za OrCAD kuti apange zida zawo zamagetsi.Kudziwa luso losinthira masinthidwe kukhala mawonekedwe a PCB mosakayikira kumakulitsa luso lanu lopanga zida zamagetsi zogwira ntchito komanso zokometsedwa.
