Usuvele uyazi ukuthi wonke amadivaysi kagesi aqukethe amabhodi wesifunda. Ama-PCB, noma amabhodi wesifunda aphrintiwe, ayingxenye ebalulekile ye-elekthronikhi yanamuhla. Ibhodi eluhlaza enezintambo eziyinkimbinkimbi namaphethini abizwa nge-PCB. Kumadivayisi we-elekthronikhi, amamaki ku-PCB aqinisekisa ukuthi zonke izinto zisebenza ndawonye. Ukwenziwa kwe-PCB kuqukethe izinto eziningi nezinyathelo. Isigaba sokugcina sokwenza ibhodi yokujikeleza ephrintiwe (PCB) ukwengeza ukuphrinta kwesikrini ku-warser ephezulu.
Ukuphrinta kwesikrini inqubo yokusebenzisa i-Ink Traces kwiBhodi Yesekethe ukukhomba izingxenye zayo, izimpawu zokuxwayisa, amaphuzu wokuhlola, amamaki, ingxenye yengxenye isikrini esishicilelwe esikrinini somkhiqizi. Ngezikhathi ezithile kuvela eziteshini ze-welding, kepha izindleko zokufika lapho ziphezulu. Ukuphrinta kwesikrini se-PCB kusiza abakhiqizi kanye nabaqambi basheshe bakhombe izakhiwo zezakhi. Ukuphrinta kwesikrini se-PCB kuzoqinisekisa ukuthi izingxenye zingahlanganiswa kabusha. Ukuphrinta kwesikrini kuzohlinzeka ngonjiniyela noma uchwepheshe ngemiyalo yokuthi izakhi kufanele zibekwe kuphi futhi kanjani kwi-PCB.
Kuyini ukuphrinta kwesikrini se-PCB?
Cabanga ukuthi usebenza kwiphrojekthi ye-DIY ukwakha i-SmartWatch ye-Futuristic kusuka ekuqaleni. I-PCB yakho ifana ne-bluepprint yalokhu ubuchwepheshe obuphakeme obugqoke, futhi ukuphrinta kwesikrini kuyindlela yakho yokwengeza amamaki anembile namalebula ukukuqondisa nanoma ngubani obambe iqhaza kwinqubo yomhlangano.
Ukuphrinta kwesikrini ku-PCB kungqimba ye-ink ephrintiwe ebusweni beBhodi Yesekethe. Imvamisa yenziwa nge-polymer noma izinto ze-ceramic futhi isetshenziswa ngokuphrinta kwesikrini. I-Ink isetshenziswa ngesikrini se-mesh, esisebenza njengesifanekiso sephethini oyifunayo. Isikrini sibekwe kwi-PCB, futhi uyinki uphoqelelwa esikrinini nakubhodi. Imibala ye-screen ejwayelekile esetshenziswa ngabakhiqizi abamnyama, aphuzi nabamhlophe. Uma usebenzisa isoftware ye-PCB, amafonti asetshenziswa kaningi angasetshenziswa ekwakhiweni kwesendlalelo sokuphrinta wesikrini.
Imvamisa isetshenziswa ezingxenyeni eziphezulu nezangaphansi zeBhodi Yesekethe. Kusetshenziswa ukuphrinta kwesikrini, ingaphezulu lebhodi le-PCB lingaphrintwa ngombhalo, amalebula nezimpawu. Izakhi, indawo yazo, amagama engxenye, izinombolo zezakhi, ama-logo womkhiqizo, nolunye ulwazi kuvezwa ngokubona.
Yize ungqimba lokuphrinta isikrini lungenakwenza lutho ngokusebenza kwangempela kagesi kweBhodi, kubalulekile kwinqubo yokwakha, ukuhlola, nokusebenzisa ibhodi. Isiza ukuthola izinto futhi sizibekele ezindaweni ezifanele ukuze konke kufakwe umugqa phezulu nangasendaweni efanele. Kuyasiza kakhulu kwinqubo yomhlangano ngoba ihlinzeka ngezikhombo ezibonakalayo okulula ukuziqonda kochwepheshe kanye nabasokisi. Manje njengoba wazi izisekelo zokuphrinta kwesikrini kumabhodi wesifunda aphrintiwe, ake sibheke ukusetshenziswa kwalo okubanzi.
Uyini ulwazi lokuphrinta kwesikrini se-PCB?
Njengoba kushiwo ngaphambili, ukuphrinta kwesikrini ku-PCB kungenzeka kungabi namphumela emsebenzini we-PCB; Kodwa-ke, inani layo lilele olwazini olunikezayo. Isibonelo, kuzosiza noma ngubani:
Izimpawu Zesixwayiso:Khomba izimpawu eziyisixwayiso ezigqamisa izingxenye eziphakeme zokushisa ezidinga ukunakwa komsebenzisi nokunakekelwa ngesikhathi sokusebenza.
Polarity:Qonda ubumbano lwengxenye yokufaka kahle ingxenye. Amamaki we-PIN ahlinzeka ngolwazi oluqondisayo ukuze aqinisekise ukuthi umhlangano onembile.
Iphuzu lokuhlola:Izinkomba zokuhlola isikhundla sesikhundla esikrinini ukusiza onjiniyela bokuqamba ekuhlolweni kwe-PCB nokuthumela.
Inkomba inkomba: Izakhi zikhonjwa yinkomba yenkomba, isikhombi esiyingqayizivele sendawo ngayinye yomhlangano kwi-PCB.
Isintu: Thola inombolo eyingqayizivele ekuphrintweni kwesikrini se-PCB, okukhombisa umaki womenzi, inombolo yenguqulo, njll.
Izimpawu zezakhi: Ngezakhi ezikhethekile ezinjenge-diodes nama-opocouplers, izimpawu zengxenye eziphrintiwe ekuphrintweni kwesikrini ziqinisekisa ukuqondanisa okunembile ngesikhathi sokufakwa.
Shintsha Izilungiselelo:Izilungiselelo zokushintsha okuzenzakalelayo zichazwa esikrinini se-PCB, kuthuthukisa ukusebenza kweBhodi.
Izingxenye eziminyene:I-PIN ekuphrintweni kwesikrini isiza ukuhlola kanye nokulungisa iphutha lamaphakeji engxenyeni ehlanganisiwe efana ne-Ball Grid Array (BGA).
Ukuxazulula inkinga nokulungisa:Ukumaka kwesikrini kungathola kalula futhi uthole izakhi ngazinye, ukusheshisa inqubo yokulungisa.
Imibhalo Yokukhiqiza:Ukumakwa kwesikrini kasilika kunikeza imibhalo edingekayo yokukhiqiza kanye nomhlangano. Lokhu kufaka phakathi izaziso ze-copyright, ama-logo enkampani, izinsuku zokukhiqiza, kanye nokunye ukulawula okubalulekile kwekhwalithi kanye nemininingwane yokulandela.
Phawula: Lezi zimpawu zinomthelela ebuhleni be-PCB kanye nomkhiqizo. Ukuhlanganisa izinto zomkhiqizo, ama-logo, nemibala ekhethiwe ithuthukisa isikhalazo sokubuka nobungcweti.
Yibuphi ubukhulu bokuphrinta kwesikrini ku-PCB?
Ubukhulu besikrini ku-PCB buthinteka ngosayizi wesikrini kanye nenani le-ink elisetshenzisiwe. Ngokuvamile, ukuphrinta kwesikrini kuma-PCB kutholakala njengenhlanganisela enhle, imvamisa ngobukhulu obungaphansi kuka-0,1 mm. Lokhu kuvumela i-ink ukuthi isetshenziswe kahle ngaphandle kokushintsha okukhulu ukuqina kwe-PCB.
Ukujula kwe-wire mesh ku-PCB kungahluka ngokuya ngezinto ezahlukahlukene, kufaka phakathi izindlela zokukhiqiza, izidingo ezithile, nezindinganiso ezisunguliwe ngaphakathi embonini. Imvamisa, ukujula kokuphrinta kwesikrini ku-PCB kuncane kuqhathaniswa nezinye izingqimba ngaphakathi kwe-PCB.
Kwezinye izimo, ukushuba kwesikrini okuphrintiwe kwe-PCB ungqimba kuvame ukuba ngu-0.02 mm kuya ku-0,1 mm (ama-microns angama-20 kuye kwayi-100). Lokhu kubalulekile ukubheka ukuthi lezi zilinganiso zilinganiselwa futhi zingahluka ngokuya ngezinto ezahlukahlukene.
Yize isikrini ebhodini lesekethe eliphrintiwe lincane, sisanikeza ukubonakala okuningi nokuqina kophawu. Ubukhulu bubhekwa ngokucophelela ukuze uqinisekise ukuthi akuphazamisi ukusebenza kwe-PCB, okubangela ukuphathwa kabi kwengxenye, noma kubangele izinkinga ngesikhathi sokukhiqiza.
