Kwi-electronics, ukuyila ibhodi yesekethe eprintiweyo (PCB) linyathelo elibalulekileyo ekuqinisekiseni ukusebenza okuchanekileyo kunye nokusebenza kakuhle.I-OrCAD yinkqubo ye-elektroniki yoyilo oluzenzekelayo (i-EDA) ebonelela ngeseti enamandla yezixhobo zokunceda iinjineli ekuguquleni ngokungenamthungo iischematics kuyilo lwePCB.Kweli nqaku, siza kuphonononga isikhokelo senyathelo nenyathelo sendlela yokuguqula isikimu sibe yi-PCB uyilo usebenzisa i-OrCAD.
Inyathelo 1: Yenza iprojekthi entsha
Phambi kokuphonononga kubeko lwePCB, kuyafuneka ukuseta iprojekthi entsha kwi-OrCAD ukuze ulungelelanise ngokufanelekileyo iifayile zakho zoyilo.Qala kuqala i-OrCAD kwaye ukhethe iProjekthi eNtsha kwimenyu.Khetha igama leprojekthi kunye nendawo kwikhompyuter yakho, emva koko ucofe u-Kulungile ukuqhubeka.
Inyathelo lesi-2: Thatha ngaphandle iSchematic
Inyathelo elilandelayo kukungenisa iskimu kwisoftware yeOrCAD.Ukwenza oku, yiya kwimenyu ethi "Ifayile" kwaye ukhethe "Ngenisa."Khetha ifomati yefayile ecwangcisiweyo efanelekileyo (umzekelo, .dsn, .sch) kwaye ukhangele kwindawo apho ifayile yesikim igcinwa khona.Nje ukuba ukhethiwe, cofa u-Ngenisa ukulayisha iskimu kwi-OrCAD.
Inyathelo 3: Qinisekisa uYilo
Ukuqinisekisa ukuchaneka nokusebenza kwesikim kubalulekile phambi kokuba kuqhutyekwe noyilo lwePCB.Sebenzisa izixhobo ezakhelwe ngaphakathi ze-OrCAD ezinje ngoHlolo loMthetho woYilo (i-DRC) ukubona naziphi na iimpazamo ezinokubakho okanye ukungangqinelani kuyilo lwakho.Ukujongana nale miba kweli nqanaba kuya konga ixesha kunye nomzamo ngexesha lenkqubo yoyilo lwePCB.
Inyathelo 4: Yenza ulwandlalo lweBhodi yePCB
Ngoku ukuba iskimu siqinisekisiwe, inyathelo elilandelayo kukwenza ulwandlalo lwebhodi yePCB.Kwi-OrCAD, yiya kwimenyu yokuBeka kwaye ukhethe ulwandlalo lweBhodi.Sebenzisa esi sixhobo ukuchaza imilo kunye nobungakanani bePCB yakho ngokweemfuno zakho.Qinisekisa ukuba ulwandlalo lwebhodi luthobela imiqobo ethile yoyilo kunye nemiqobo yoomatshini (ukuba ikhona).
Inyathelo lesi-5: Ukubeka Amacandelo
Inqanaba elilandelayo libandakanya ukubeka amacandelo kuyilo lwePCB.Sebenzisa izixhobo zokubeka zecandelo le-OrCAD ukutsala nokulahla izinto eziyimfuneko kwithala leencwadi kwiPCB.Qinisekisa ukuba ubeka amacandelo ngendlela eyandisa ukuhamba komqondiso, ukunciphisa ingxolo, kwaye ulandele izikhokelo ze-DRC.Nika ingqalelo uqhelaniso lwamacandelo, ngakumbi amacandelo e-polarizing.
Inyathelo 6: Uqhagamshelo lomzila
Emva kokubeka amacandelo, inyathelo elilandelayo kukuhambisa unxibelelwano phakathi kwabo.I-OrCAD ibonelela ngezixhobo ezinamandla zendlela ukunceda ngokufanelekileyo iingcingo zendlela ukwenza uqhagamshelo lombane.Gcina ukhumbula izinto ezinje ngemfezeko yomqondiso, ukuthelekisa ubude, kunye nokunqanda ukuwela xa usendleleni.Inqaku le-OrCAD le-autorouting liyenza lula ngakumbi le nkqubo, nangona ukuhanjiswa ngesandla kucetyiswa kuyilo oluntsonkothileyo.
Inyathelo 7: Ukujongwa koMthetho woYilo (DRC)
Phambi kokugqibezela uyilo lwePCB, kubalulekile ukwenza uqwalaselo lomgaqo woyilo (i-DRC) ukuqinisekisa ukuthotyelwa kwemiqobo yokuvelisa.Indawo ye-OrCAD ye-DRC izibhaqa ngokuzenzekelayo iimpazamo ezinxulumene nezithuba, ukucocwa, imaski ye-solder, kunye neminye imithetho yoyilo.Lungisa nayiphi na imiba ephawulwe sisixhobo se-DRC ukuqinisekisa ukuba uyilo lwePCB luyavezwa.
Inyathelo lesi-8: Yenza iiFayile zokuVelisa
Nje ukuba ubeko lwe-PCB lungenazimpazamo, iifayile zokwenziwa ezifunekayo kukwenziwa kwe-PCB kunokuveliswa.I-OrCAD ibonelela ngendlela elula yokuvelisa iifayile zeGerber ezisemgangathweni, iBhili yeMpahla (BOM) kunye nezinye iziphumo ezifunekayo.Iifayile eziveliswayo ziqinisekisiwe kwaye kwabelwana ngazo kunye nabavelisi ukuze kuqhutyekwe nokwenziwa kwe-PCB.
Ukuguqula izicwangciso zibe yi-PCB uyilo usebenzisa i-OrCAD kubandakanya inkqubo ecwangcisiweyo eqinisekisa ukuchaneka koyilo, ukusebenza, kunye nokwenziwa.Ngokulandela esi sikhokelo sibanzi senyathelo nenyathelo, iinjineli kunye nee-hobbyists zinokuwasebenzisa ngempumelelo amandla e-OrCAD ukuzisa uyilo lwabo lwe-elektroniki ebomini.Ukuba nobuchule bokuguqula isikimu sibe yiPCB ngokungathandabuzekiyo kuya kuphucula isakhono sakho sokwenza uyilo olusebenzayo noluphuculweyo lwe-elektroniki.
