nzira yekushandura schematic kune pcb dhizaini mu orcad

Mune zvemagetsi, kugadzira bhodhi redunhu rakadhindwa (PCB) inhanho yakakosha mukuona kushanda kwakaringana uye kuita kwakakwana.OrCAD inozivikanwa yemagetsi dhizaini otomatiki (EDA) software inopa yakasimba seti yezvishandiso zvekubatsira mainjiniya mukushandura zvisina mutsetse schematics kuPCB marongero.Muchikamu chino, tichaongorora nhanho-ne-nhanho gwara rekushandura schematic kuita PCB dhizaini uchishandisa OrCAD.

Danho 1: Gadzira chirongwa chitsva

Usati wapinda muPCB dhizaini, zvinodikanwa kumisikidza purojekiti nyowani muOrCAD kuti unyatso kuronga mafaera ako ekugadzira.Kutanga tanga OrCAD uye sarudza New Project kubva kumenyu.Sarudza zita repurojekiti nenzvimbo pakombuta yako, wobva wadzvanya OK kuti uenderere mberi.

Danho 2: Ngenisa Schematic

Nhanho inotevera ndeyekutumira iyo schematic muOrCAD software.Kuti uite izvi, enda ku "Faira" menyu uye sarudza "Import."Sarudza yakakodzera schematic file format (eg, .dsn, .sch) uye famba uchienda kunzvimbo iyo faira yefaira inochengetwa.Kana wangosarudzwa, tinya Import kuti uise schematic muOrCAD.

Danho rechitatu: Simbisa Dhizaini

Kuve nechokwadi chechokwadi uye kushanda kweiyo schematic kwakakosha usati waenderera nePCB marongero.Shandisa OrCAD yakavakirwa-mukati maturusi akadai sedhizaini Rule Kutarisa (DRC) kuona chero zvikanganiso zvingangoitika kana kusawirirana mumagadzirirwo ako.Kugadzirisa nyaya idzi panguva ino kuchachengetedza nguva uye kushanda nesimba panguva yePCB marongerwo maitiro.

Danho 4: Gadzira PCB Board Outline

Iye zvino hurongwa hwave hwakasimbiswa, nhanho inotevera kugadzira iyo chaiyo PCB bhodhi rondedzero.MuOrCAD, famba uchienda kuMenu yekuisa uye sarudza Board Outline.Shandisa chishandiso ichi kutsanangura chimiro uye saizi yePCB yako zvinoenderana nezvaunoda.Ita shuwa kuti iyo bhodhi rondedzero inoenderana neyakajeka dhizaini zvipingaidzo uye zvimhingamipinyi zvemuchina (kana zviripo).

Nhanho 5: Kuisa Zvikamu

Nhanho inotevera inosanganisira kuisa zvikamu paPCB marongerwo.Shandisa OrCAD's chikamu chekuisa maturusi kudhonza nekudonhedza zvinodikanwa kubva muraibhurari kuenda kuPCB.Ita shuwa yekuisa zvikamu nenzira inogonesa kuyerera kwechiratidzo, kuderedza ruzha, uye kutevera zvirevo zveDRC.Teerera kune kutaridzika kwechikamu, kunyanya polarizing zvikamu.

Danho 6: Routing Connections

Mushure mekuisa zvikamu, danho rinotevera nderekufambisa hukama pakati pavo.OrCAD inopa maturusi ane simba ekufambisa kuti abatsire nemazvo nzira waya kugadzira magetsi.Ramba uchifunga zvinhu zvakaita sechiratidzo chekuvimbika, kureba kuenzanirana, uye kudzivirira macrossovers paunenge uchifamba.OrCAD's autorouting chimiro inowedzera kurerutsa maitiro aya, kunyangwe manyorerwo ekufambisa achikurudzirwa kune mamwe madhizaini akaomarara.

Danho rechinomwe: Dhizaini Rule Tarisa (DRC)

Usati wapedzisa dhizaini yePCB, zvakakosha kuti uite dhizaini yekutarisa mutemo (DRC) kuti uve nechokwadi chekutevedzera zvimhingamipinyi zvekugadzira.OrCAD's DRC ficha inoona otomatiki zvikanganiso zvine chekuita nepakati, clearance, solder mask, uye mimwe mitemo yekugadzira.Gadzirisa chero nyaya dzakamisikidzwa neDRC chishandiso kuona kuti PCB dhizaini inogadzirwa.

Nhanho 8: Gadzira Manufacturing Files

Kana iyo PCB dhizaini isina kukanganisa, mafaira ekugadzira anodiwa paPCB yekugadzira anogona kugadzirwa.OrCAD inopa nzira iri nyore yekugadzira indasitiri yakajairwa maGerber mafaera, Bhiri reZvishandiso (BOM) uye zvimwe zvinodiwa zvinobuda.Mafaira akagadzirwa anosimbiswa uye anogovaniswa nevagadziri kuti vaenderere mberi nePCB kugadzira.

Kushandura schematics kuPCB marongero uchishandisa OrCAD kunosanganisira maitiro akarongeka anovimbisa kurongeka kwedhizaini, kushanda, uye kugadzira.Nekutevera iyi yakazara nhanho-ne-nhanho gwara, mainjiniya uye hobbyists vanogona kunyatso shandisa simba reOrCAD kuunza zvigadzirwa zvemagetsi kuhupenyu.Kugona hunyanzvi hwekushandura schematic kuita PCB dhizaini pasina mubvunzo kunosimudzira kugona kwako kugadzira anoshanda uye akakwenenzverwa emagetsi dhizaini.
