momwe mungapangire masanjidwe a pcb kuchokera pazithunzi zozungulira

Njira yosinthira mawonekedwe a chigawo kukhala gulu losindikizidwa losindikizidwa (PCB) ikhoza kukhala ntchito yovuta, makamaka kwa oyamba kumene mu zamagetsi.Komabe, ndi chidziwitso cholondola ndi zida, kupanga mawonekedwe a PCB kuchokera pamalingaliro kungakhale kosangalatsa komanso kopindulitsa.Mubulogu iyi, tiwona njira zomwe zimaphatikizidwa popanga masanjidwe a PCB kuchokera pazithunzi zozungulira, kukupatsirani zidziwitso zofunikira kuti muthe luso la mapangidwe a PCB.

Gawo 1: Dziwani Zojambula Zozungulira

Kumvetsetsa bwino mawonekedwe ozungulira ndikofunikira musanadumphire pamapangidwe a PCB.Dziwani zigawo, kulumikizana kwake, ndi zofunikira zilizonse pakupanga.Izi zikuthandizani kuti mukonzekere ndikukhazikitsa masanjidwe bwino.

Khwerero 2: Chithunzi chozungulira chotumizira

Kuyambitsa dongosolo masanjidwe kamangidwe, muyenera kusamutsa schematic anu PCB kapangidwe mapulogalamu.Pali mitundu yosiyanasiyana yamapulogalamu pamsika, onse aulere komanso olipidwa, okhala ndi milingo yosiyanasiyana yaukadaulo.Sankhani yomwe ikugwirizana ndi zomwe mukufuna komanso luso lanu.

Gawo 3: Kuyika kwagawo

Chotsatira ndikuyika zigawo pa PCB masanjidwe.Pali zinthu zingapo zomwe zimaganiziridwa poyala zinthu, monga njira zolumikizirana, kulumikizana ndi mphamvu, ndi zopinga zakuthupi.Konzani masanjidwe anu m'njira yomwe imawonetsetsa kusokoneza kochepa komanso kuchita bwino.

Khwerero 4: Wiring

Pambuyo poyika zigawo, sitepe yotsatira yovuta ndiyo kuyendetsa.Kutsata ndi njira zamkuwa zomwe zimagwirizanitsa zigawo pa PCB.Yang'anirani mazizindikiro ofunikira poyamba, monga ma frequency apamwamba kapena mizere yovuta.Gwiritsani ntchito njira zamapangidwe zoyenera, monga kupewa kusongoka ndi kuwoloka njira, kuti muchepetse kusokoneza ndi kusokoneza.

Khwerero 5: Mapulani Apansi ndi Mphamvu

Phatikizani ndege zoyenera pansi ndi mphamvu mu mapangidwe a PCB.Ndege yapansi imapereka njira yochepetsera yobwereranso pakalipano, kuchepetsa phokoso ndikuwongolera kukhulupirika kwa chizindikiro.Momwemonso, ndege zamagetsi zimathandizira kugawa mphamvu molingana ndi gulu lonse, kuchepetsa kutsika kwamagetsi ndikuwonjezera mphamvu.

Khwerero 6: Chongani Malamulo Opangira (DRC)

Mukamaliza masanjidwe, Kuwunika kwa Design Rule (DRC) kuyenera kuchitidwa.DRC imayang'ana kapangidwe kanu motsutsana ndi malamulo ndi zomwe zafotokozedweratu, ndikuwonetsetsa kuti masanjidwewo akukwaniritsa zofunikira.Dziwani zovomerezeka, kutsata makulidwe, ndi magawo ena apangidwe panthawiyi.

Khwerero 7: Pangani Mafayilo Opanga

Pambuyo podutsa bwino ku DRC, mafayilo opanga amatha kupangidwa.Mafayilowa akuphatikizapo mafayilo a Gerber ndi Bill of Equipment (BOM), yomwe ili ndi deta yofunikira pakupanga PCB, ndikulemba zigawo zonse zofunika pa msonkhano.Onetsetsani kuti zolemba zopanga ndi zolondola komanso zikugwirizana ndi zomwe wopanga akufuna.

Pomaliza:

Kupanga masanjidwe a PCB kuchokera pachimake kumaphatikizapo njira yokhazikika kuyambira pakumvetsetsa dera mpaka kupanga zolemba zopanga.Chilichonse pakuchitapo kanthu chimafuna chidwi chatsatanetsatane komanso kukonzekera bwino.Potsatira izi ndikugwiritsa ntchito zida ndi mapulogalamu omwe alipo, mutha kudziwa luso la mapangidwe a PCB ndikupangitsa kuti schematics yanu ikhale yamoyo.Chifukwa chake tembenuzani manja anu ndikulola kuti luso lanu ndi luso lanu ziyende bwino mu dziko la mapangidwe a PCB!
