dziwitsani
Pulojekiti yosindikizidwa (PCB) ndiyo msana wa zipangizo zamagetsi, zomwe zimapereka nsanja yolumikizira ndi kuthandizira zida zosiyanasiyana zamagetsi.Kupanga PCB kungawoneke ngati kovuta, makamaka kwa oyamba kumene, koma ndi chidziwitso ndi njira yoyenera, ikhoza kukhala njira yosangalatsa komanso yopindulitsa.Mubulogu iyi, tikuyendetsani njira zoyambira ndikuganizira kuti mupange bwino PCB yanu kuyambira poyambira.
1. Kumvetsetsa zofunikira pakupanga
Musanayambe ulendo wa mapangidwe a PCB, ndikofunikira kufotokozera momveka bwino zofunikira za polojekiti.Dziwani cholinga cha bolodi, ntchito yake, ndi zigawo zake zomwe zikufunika kuti zikhazikike.Dziwani zambiri zamagetsi, kukula kofunikira, ndi zina zilizonse zapadera kapena ntchito zomwe zimafunikira.
2. Lembani ndikukonzekera masanjidwewo
Kupanga schema ndi poyambira pamapangidwe aliwonse a PCB.Pogwiritsa ntchito zida zamapulogalamu monga EAGLE, KiCAD kapena Altium, mutha kusintha malingaliro anu kukhala zithunzi zamakonzedwe.Izi zimaphatikizapo kulumikiza zigawo pakompyuta, kutsogolera njira ya zizindikiro zamagetsi.
Kenako, mawonekedwe a PCB ayenera kukonzedwa.Ganizirani zinthu monga kaikidwe kagawo, njira yotsata ma sign, kuyika magetsi, ndi ndege zapansi.Onetsetsani kuti masanjidwewo akugwirizana ndi malamulo opangira makampani komanso njira zabwino zopewera kusokonezedwa ndi ma sign kapena phokoso.
3. Kusankha zigawo ndi kuika
Kusankha zigawo zoyenera za PCB ndikofunikira kwambiri pamachitidwe ake ndi magwiridwe ake.Ganizirani zinthu monga ma voliyumu, zofunikira pano, komanso kufananira ndi zigawo zina.Fufuzani ndi kupeza zinthu zabwino kwambiri kuchokera kwa ogulitsa odziwika.
Kuyika kwachinthu moyenera ndikofunikira pakuwonetsetsa kuti PCB yapangidwa mwadongosolo komanso yaying'ono.Ikani zigawo mwanzeru poganizira za kayendedwe ka ma siginecha, zofunikira za mphamvu, ndi malingaliro amafuta.Ndikofunikiranso kulola chilolezo chokwanira pakati pa zigawo kuti zisasokonezedwe panthawi ya soldering kapena board.
4. Njira zotsatsira PCB
Kutsata njira kumatanthauza kupanga njira zamkuwa zomwe zimalumikiza magawo osiyanasiyana pa PCB.Zizindikiro, mphamvu, ndi mayendedwe apansi ziyenera kukonzedwa bwino.Tsatirani dongosolo losanjikiza kuti mulekanitse ma siginecha othamanga kwambiri komanso okhudzidwa ndi maphokoso kapena amphamvu kwambiri.
Zinthu monga kutsata m'lifupi, kufananiza kutalika, ndi kuwongolera kwa impedance zimagwira ntchito yofunika kwambiri pakuwonetsetsa kwazizindikiro ndi kulimba.Onetsetsani kuti mukutsatira malamulo apangidwe ndi malangizo operekedwa ndi zida za mapulogalamu kuti mupewe zovuta zomwe zingatheke panthawi yopanga.
5. Malamulo ndi Mapangidwe Ovomerezeka
Mukamaliza kukonza, ndikofunikira kutsimikizira kapangidwe kake musanamalize.Chitani zowunikira malamulo apangidwe (DRC) kuti muwone zolakwika kapena zophwanya.Gawoli limatsimikizira kuti kapangidwe kake kamagwirizana ndi zopinga zopanga komanso zomwe zimafunikira.
6. Lembani ndi kupanga zolemba zopanga
Kulemba molondola mapangidwe a PCB ndikofunikira kuti muwafotokozere mtsogolo ndikuwongolera.Pangani owona zofunika kupanga, kuphatikizapo Gerber owona, kubowola owona, ndi Bill of Materials (BOM).Yang'ananinso mafayilo kuti muwonetsetse kuti akuyimira bwino mapangidwe anu.
Pomaliza
Kupanga PCB yanu kuyambira pachiyambi kungawoneke ngati ntchito yovuta poyamba, koma ndi kuleza mtima, kuchita, ndi njira yoyenera, ikhoza kukhala yosangalatsa.Pomvetsetsa zofunikira pakupanga, kukonzekera bwino masanjidwe, kusankha zigawo zoyenera, kuyendetsa bwino, ndikuwonetsetsa kutsimikizika kwa mapangidwe, mutha kupanga ma PCB ogwira ntchito komanso odalirika.Ndiye dikirani?Lowani m'dziko la mapangidwe a PCB ndikusintha mapulojekiti anu amagetsi!
