Takulandilani ku kalozera wathu wamomwe mungapangire PCB (Bodi Losindikizidwa Lozungulira)!Mu positi iyi yabulogu, tikuyendetsani njira yopangira PCB kuyambira poyambira, ndikukupatsani malangizo atsatane-tsatane ndi malangizo othandiza panjira.Kaya ndinu munthu wokonda kusangalala, wophunzira, kapena wokonda zamagetsi, bukuli lakonzedwa kuti likuthandizeni kupanga bwino ndikupanga ma PCB anu.Choncho, tiyeni tione mozama!
1. Mvetserani zoyambira za mapangidwe a PCB:
Tisanalowe mukupanga, ndikofunikira kumvetsetsa zoyambira za mapangidwe a PCB.Dziwani bwino zida zofunikira zamapulogalamu, monga pulogalamu ya EDA (Electronic Design Automation), yomwe imakupatsani mwayi wopanga ndi kupanga mapangidwe ozungulira.
2. Kapangidwe kachiwembu:
Yambani ndikulingalira dera lanu pogwiritsa ntchito schematic.Gawo lofunikirali limakupatsani mwayi wokonzekera pomwe gawo lililonse lidzayikidwa pa bolodi.Mugawo lonseli, onetsetsani kuti chiwembucho chikutsatira njira zabwino zowonetsera momveka bwino komanso mwachidule.
3. Pangani mapangidwe a PCB:
Chiwembucho chikakonzeka, chimasamutsidwa ku mapulogalamu a PCB.Zigawo zimayikidwa pa bolodi poyamba, ndikusamala kuzikonza bwino kuti ziziyenda bwino.Kumbukirani kuganizira zinthu monga kukula kwa chigawocho, kulumikizana, ndi kutayika kwa kutentha.
4. Njira:
Kuyenda kumaphatikizapo kupanga njira kapena njira zolumikizira zinthu zosiyanasiyana pa PCB.Dziwani mosamalitsa mayendedwe a njira iliyonse, poganizira zinthu monga kukhulupirika kwa chizindikiro, kugawa mphamvu, ndi ndege zapansi.Samalirani kwambiri malamulo ovomerezeka ndikuwonetsetsa kuti mapangidwe anu akugwirizana ndi zovomerezeka zopanga.
5. Kutsimikizira kwapangidwe:
Mapangidwe anu ayenera kutsimikiziridwa bwino musanapitirize ndi kupanga.Chitani Design Rule Check (DRC) ndikuwona masanjidwe anu kuchokera mbali iliyonse.Onetsetsani kuti zizindikirozo zalekanitsidwa bwino ndipo palibe akabudula omwe angakhalepo.
6. Njira yopangira:
Mukakhutitsidwa ndi mapangidwe anu a PCB, njira yopangira ikhoza kuyamba.Yambani ndikusamutsa kapangidwe kanu ku bolodi lovala zamkuwa pogwiritsa ntchito PCB yophimbidwa kale kapena njira yosinthira tona.Mangani bolodi kuti muchotse mkuwa wochulukirapo, ndikusiya zotsalira zokha ndi mapepala.
7. Kubowola ndi plating:
Pogwiritsa ntchito pobowola pang'ono, kubowola mabowo mosamala m'malo osankhidwa pa PCB.Mabowowa amagwiritsidwa ntchito kukwera zigawo ndi kupanga kulumikiza magetsi.Pambuyo pobowola, mabowowo amakutidwa ndi kagawo kakang'ono kakang'ono ka zinthu monga mkuwa kuti apititse patsogolo madutsidwe.
8. Zida zowotcherera:
Tsopano ndi nthawi kusonkhanitsa zigawo pa PCB.Solder chigawo chilichonse m'malo mwake, kuonetsetsa kulumikizidwa bwino ndi zolumikizira zabwino za solder.Ndi bwino kugwiritsa ntchito soldering chitsulo ndi mphamvu yoyenera ndi kutentha kuteteza zigawo zikuluzikulu ndi PCB.
9. Kuyesa ndi Kuthetsa Mavuto:
Pambuyo soldering watha, m'pofunika kuyesa magwiridwe a PCB.Gwiritsani ntchito ma multimeter kapena zida zoyenera zoyesera kuti muwone ngati pali kulumikizana, kuchuluka kwamagetsi ndi zolakwika zomwe zingachitike.Konzani mavuto aliwonse omwe angabwere ndikupanga kusintha kofunikira kapena kusintha magawo.
Pomaliza:
Zabwino zonse!Mwangophunzira kupanga PCB kuyambira poyambira.Potsatira chiwongolero chonsechi, tsopano mutha kupanga, kupanga ndi kusonkhanitsa matabwa anu osindikizidwa.Kupanga kwa PCB ndi njira yosangalatsa koma yovuta yomwe imafuna chidwi chatsatanetsatane, kuleza mtima komanso chidziwitso chamagetsi.Kumbukirani kuyesa ndikuvomereza njira yophunzirira.Ndikuchita, mudzakhala ndi chidaliro ndikutha kupanga mapangidwe ovuta kwambiri a PCB.Kuchita bwino kwa PCB!
