Kupanga bolodi losindikizidwa (PCB) kungawoneke ngati ntchito yovuta, makamaka kwa oyamba kumene. Komabe, ndi chitsogozo choyenera ndi chidziwitso, aliyense angathe kuphunzira kupanga mapangidwe awoawo a PCB. Muupangiri woyambira uyu, tipereka malangizo atsatanetsatane amomwe mungapangire PCB kuyambira poyambira. Kotero, tiyeni tilowe mkati!
Khwerero 1: Kukonzekera Mapangidwe a PCB
Musanayambe ndondomeko yachitukuko cha PCB, ndikofunika kumvetsetsa bwino zomwe mukufuna polojekiti yanu. Dziwani cholinga cha PCB, zigawo zomwe zingathandizire, ndi magwiridwe antchito ofunikira. Pangani schematics kuti muwonetsetse kugwirizana kwa madera ndikuwonetsetsa kuti mamangidwe osasunthika.
Khwerero 2: Pangani Mapangidwe a PCB
Chiwembucho chikakonzeka, mawonekedwe a PCB atha kupangidwa. Sankhani pulogalamu yodalirika ya mapangidwe a PCB monga Eagle, Altium Designer kapena KiCad kuti mupange bolodi lanu. Yambani ndikuyika zigawo mwadongosolo pa bolodi, kuwonetsetsa kuti pali kulumikizana kwakanthawi kochepa. Samalani ndege zapansi, njira zamagetsi, ndi kukhulupirika kwa chizindikiro. Kumbukirani kusunga malo oyenera ndikusunga zinthu zofunika kutali ndi malo aphokoso.
Khwerero 3: Masanjidwe ndi Kutsata Kuyika
Kuwongolera kumaphatikizapo kupanga zotsalira zamkuwa zomwe zimalumikiza zigawo pa PCB. Ikani zizindikiro m'njira yoti phokoso ndi kusokoneza kwa zizindikiro zichepetse. Gwirizanitsani zigawo zofananira pamodzi ndipo pewani kuwoloka ngati kuli kofunikira. Onetsetsani kuti pali kusiyana koyenera pakati pa zilombo kuti mupewe njira zazifupi. Ngati mukugwiritsa ntchito zida zokwera pamwamba, onetsetsani kuti zotsalirazo ndizochepa kwambiri kuti zigwirizane ndi gawolo.
Khwerero 4: Malizitsani Kupanga
Yang'anani bwino kapangidwe kanu ka PCB kakulondola komanso kolondola. Yang'anani zolakwika zilizonse zamapangidwe, malumikizidwe onyalanyazidwa, kapena zolakwika zapagawo. Gwiritsani ntchito chowunikira malamulo a pulogalamuyo kuti muzindikire zovuta zilizonse. Zonse zikatsimikiziridwa, mafayilo opanga amapangidwa, kuphatikizapo mafayilo a Gerber ndi Bill of Materials (BOM), kuti atsimikizire kupanga kolondola kwa PCB.
Khwerero 5: Kupanga ndi Kumanga
Tumizani mapangidwe anu omaliza a PCB kwa wopanga zomwe mukufuna. Ntchito zosiyanasiyana zapaintaneti za PCB zimapereka zosankha zotsika mtengo popanga mapangidwe anu. Sankhani magawo oyenerera monga ma sheet, kuchuluka kwa zigawo ndi makulidwe malinga ndi zomwe mukufuna. Mukamaliza kupanga PCB, yitanitsani zofunikira ndikuyamba kusonkhanitsa bolodi. Onetsetsani kuti mukutsatira njira zabwino kwambiri za soldering kuti mupewe kuwonongeka kwa zigawozo.
Khwerero 6: Kuyesa ndi Kuthetsa Mavuto
Pambuyo PCB anasonkhana, m'pofunika kuyesa magwiridwe ake. Gwiritsani ntchito ma multimeter kapena oscilloscope kuti muwone kuchuluka kwa magetsi, kukhulupirika kwa ma siginecha, ndi kulumikizana koyenera. Yambitsani PCB ndikuyesa gawo lililonse payekhapayekha. Ngati pali zovuta zomwe zapezeka, gwiritsani ntchito luso lanu lowongolera kuti muwathetse ndikuwongolera moyenera.
Kupanga PCB poyamba kungawoneke ngati njira yovuta, koma ndi njira yokhazikika komanso kumvetsetsa koyenera, kumakhala ntchito yotheka. Buku la oyambitsa uyu limapereka ndondomeko ya pang'onopang'ono ya momwe mungapangire PCB kuyambira pokonzekera mapangidwe mpaka kuyesa ntchito yake. Monga ndi luso lililonse, kuchita komanso kuchitapo kanthu kumakulitsa luso lanu pakukula kwa PCB. Chifukwa chake lowani mkati, kulimbana ndi vutoli, ndikulola kuti luso lanu liziyenda pakupanga ma PCB ogwira ntchito. Zabwino zonse!
