Isikrini sikasilika se-PCBukuphrinta kuyinqubo ebalulekile ekukhiqizeni amabhodi wesifunda we-PCB, okunquma izinga lebhodi le-PCB eliphelile. Ukwakhiwa kwebhodi lesifunda se-PCB kuyinkimbinkimbi kakhulu. Kunemininingwane eminingi emincane enqubweni yokuklama. Uma ingaphathwa kahle, izothinta ukusebenza kwebhodi le-PCB lonke. Ukuze kwandiswe ukusebenza kahle kwedizayini kanye nekhwalithi yomkhiqizo, yiziphi izinkinga okufanele sizinake ngesikhathi sokuklama?
Ihluzo zomlingiswa zakhiwa ebhodini le-pcb ngesikrini sikasilika noma ukuphrinta kwe-inkjet. Umlingiswa ngamunye umele ingxenye ehlukile futhi udlala indima ebaluleke kakhulu ekwakhiweni kwakamuva.
Ake ngethule abalingisi abavamile. Ngokuvamile, u-C umele i-capacitor, u-R umele ukuphikiswa, u-L umele i-inductor, u-Q umele i-transistor, u-D umele i-diode, u-Y umele i-crystal oscillator, u-U umele i-integrated circuit, B imele i-buzzer, T imele i-transistor, K. imele i-Relays nokunye.
Ebhodini lesifunda, sivame ukubona izinombolo ezifana no-R101, C203, njll. Eqinisweni, uhlamvu lokuqala lumelele isigaba sengxenye, inombolo yesibili ikhomba inombolo yokusebenza kwesekhethi, kanti izinombolo zesithathu nesine zimelela inombolo ye-serial kusekhethi. ibhodi. Ngakho-ke siqonda kahle ukuthi i-R101 iyisivimbeli sokuqala kumjikelezo wokuqala osebenzayo, futhi i-C203 iyi-capacitor yesithathu kumjikelezo wokusebenza kwesibili, ukuze ukuhlonza uhlamvu kube lula ukukuqonda.
Eqinisweni, izinhlamvu ezisebhodini lesifunda le-PCB yilokho esivame ukukubiza ngokuthi isikrini sikasilika. Into yokuqala abathengi abayibonayo lapho bethola ibhodi le-PCB isikrini sikasilika kuso. Ngezinhlamvu zesikrini sikasilika, bangaqonda ngokucacile ukuthi yiziphi izingxenye okufanele zibekwe endaweni ngayinye ngesikhathi sokufakwa. Kulula ukuhlanganisa isichibi nokulungisa. Ngakho-ke yiziphi izinkinga okufanele ziqashelwe ohlelweni lokuklama lokuphrinta isikrini sikasilika?
1) Ibanga phakathi kwesikrini sikasilika nephedi: isikrini sikasilika asikwazi ukubekwa phezu kwephedi. Uma iphedi imbozwe isikrini sikasilika, izoba nomthelela ekuhlanganisweni kwezingxenye, ngakho-ke isikhala esingu-6-8mil kufanele sibekelwe.2) Ububanzi bokuphrinta kwesikrini: Ububanzi bomugqa wokuphrinta kwesikrini ngokuvamile bungaphezu kuka-0.1mm (4 mill), okusho ububanzi bukayinki. Uma ububanzi bomugqa buncane kakhulu, uyinki ngeke uphume esikrinini sokuphrinta, futhi izinhlamvu zingakwazi ukuphrinta.3) Ubude bezinhlamvu zokuphrinta isikrini sikasilika: Ubude bezinhlamvu ngokuvamile bungaphezu kuka-0.6mm (25mil). Uma ubude bezinhlamvu bungaphansi kuka-25mil, izinhlamvu eziphrintiwe ngeke zicace futhi zifiphaliswe kalula. Uma umugqa wezinhlamvu ushubile kakhulu noma ibanga liseduze kakhulu, kuzodala ukufiphala.
4) Isiqondiso sokuphrinta kwesikrini sikasilika: ngokuvamile landela isimiso sokusuka kwesobunxele kuye kwesokudla futhi kusukela phansi kuya phezulu.
5) Incazelo ye-polarity: Izingxenye ngokuvamile zine-polarity. Idizayini yokuphrinta isikrini kufanele inake ukumaka izigxobo ezinhle nezingezinhle kanye nezingxenye eziqondisayo. Uma izigxobo ezinhle nezingezinhle zihlehliswa, kulula ukubangela isifunda esifushane, okwenza ibhodi lesifunda lishise futhi alikwazi ukumbozwa.
6) Ukuhlonza iphinikhodi: Ukuhlonza iphini kungahlukanisa isiqondiso sezingxenye. Uma izinhlamvu zesikrini sikasilika zimaka ukuhlonza ngokungalungile noma kungekho ukuhlonza, kulula ukubangela ukuthi izingxenye zifakwe ngokuhlehla.
7) Isimo sesikrini sikasilika: Ungabeki umklamo wesikrini sikasilika embotsheni ebhoboziwe, ngaphandle kwalokho ibhodi le-pcb eliphrintiwe lizoba nezinhlamvu ezingaphelele.
Kukhona ukucaciswa okuningi kanye nezidingo zokwakheka kwesikrini sikasilika se-PCB, futhi yilezi zicaciso ezikhuthaza ukuthuthukiswa kobuchwepheshe bokuphrinta isikrini se-PCB.
