Takulandilaninso, okonda ukadaulo komanso okonda DIY! Masiku ano, chidwi chathu chili pa matabwa a PCB, kutanthauza, matabwa osindikizidwa. Izi zing'onozing'ono koma zofunika kwambiri zili pamtima pa zipangizo zambiri zamagetsi ndipo zimakhala ndi udindo woonetsetsa kuti zikugwira ntchito bwino. Kaya ndinu mainjiniya waluso kapena wokonda kuchita masewera olimbitsa thupi, kudziwa momwe mungayang'anire bolodi la PCB ndikofunikira kuti muthane ndi mavuto ndi kukonza zida zamagetsi. Chifukwa chake, tiyeni tilowe munjira zofunika kuyesa ndikuwonetsetsa kudalirika kwa bolodi la PCB!
1. Kuyang'ana m'maso:
Gawo loyamba pakuwunika PCB ndikuwunika mozama. Yang'anani pa bolodi kuti muwone kuwonongeka kulikonse, monga dzimbiri, zida zowotchedwa, kapena zolumikizana zotayirira. Yang'anani zizindikiro za kusweka kapena kuwonongeka, zigawo zosagwirizana, kapena zizindikiro za kutentha kwambiri. Kuwunika kowoneka kungawoneke kosavuta, koma kungathandize kuzindikira zovuta zomwe zingayambitse.
2. Kuyang'anira zigawo:
Pambuyo kuyendera zithunzi, chitani kuyendera chigawo chilichonse pa bolodi PCB. Yambani ndikuwonetsetsa kuti zigawo zonse zayikidwa, zolumikizidwa, ndikugulitsidwa bwino. Gwiritsani ntchito ma multimeter kuyeza kukana ndi kupitiliza kwa ma capacitor, resistors, ndi zida zina zamagetsi. Samalani kwambiri ndi zigawo zomwe zimatha kulephera, monga ma capacitors okhala ndi nsonga zotuluka kapena zowotcha zopinga.
3. Mphamvu pamayeso:
Mukamaliza kuyang'ana ndi kuyang'ana mbali, ndi nthawi yoti muyesere mphamvu. Lumikizani bolodi la PCB ku gwero lamphamvu lodalirika malinga ndi zomwe wopanga. Yang'anirani bolodi lanu la mavabodi kuti muzichita zachilendo, monga kutentha kwambiri, kusuta, kapena kuzimitsa mwadzidzidzi. Chonde samalani kuti musakhudze zida zilizonse pomwe bolodi ili yoyatsidwa, chifukwa ma voltages okwera amatha kubweretsa ngozi.
4. Mayeso a Signal:
Kuwonjezera pa kuyesa mphamvu, zizindikiro zotumizidwa ndi kulandiridwa ndi bolodi la PCB ziyenera kufufuzidwanso. Gwiritsani ntchito oscilloscope kuti muwunikire ma siginecha ndi ma voltages ndikufananiza ndi zomwe zimafunikira. Onetsetsani kuti chizindikirocho ndi chokhazikika popanda kusokoneza kapena kusinthasintha. Izi ndizovuta, makamaka m'ma board ovuta a PCB pomwe zigawo zingapo zimagwirizana.
5. Kuyesa kogwira ntchito:
Pofuna kuonetsetsa kuti bolodi la PCB likuyenda bwino, ndikofunikira kuti muyesetse ntchito. Lumikizani bolodi ku chipangizo choyenera chomwe chimagwirira ntchito, monga mota kapena sensa. Onetsetsani kuti bolodi la PCB likuchita ntchito yake yoyenerera bwino. Onetsetsani kuti maulalo olowera ndi zotuluka ndi olondola komanso kuti magwiridwe antchito onse akugwira ntchito momwe amayembekezera. Gawoli lingafunike zida zapamwamba kwambiri monga logic analyzer kapena ntchito jenereta, kutengera zovuta za board ya PCB.
Zabwino zonse! Potsatira masitepe pamwamba, mwaphunzira mmene bwino fufuzani magwiridwe ndi ntchito ya bolodi PCB wanu. Kumbukirani, kuyesa kolondola ndikofunikira kuti mutsimikizire kuti zida zanu zamagetsi zimagwira ntchito bwino komanso modalirika. Ngati pali vuto lililonse pakuyesedwa, kumvetsetsa chomwe chimayambitsa ndiye njira yoyamba yothetsera vutoli. Zikawonongeka kwambiri kapena zovuta, funani thandizo la akatswiri kwa akatswiri a PCB kapena akatswiri okonza zamagetsi nthawi yomweyo. Khalani ndi chidwi, pitilizani kuphunzira, ndipo sangalalani ndi kuyesa kwa PCB board!
