Izindlela Zokudala Zomoduli we-Camera Circuit Boards

Isayithi ye-PCB yemoduli we-khamela kumele isetshenziswe ngokuzithokozisa, futhi kunezinye izimo eziningi ezifanele ukwenza ngazo, kanye nalesi sikhathi kunezinye izindlela zokwenza:

Izindlela Zokwenza.

Ukuthuthukiswa kweSignal: Uma kuyathuthuka okukhulu kwezinyathelo zokuzithutha njengoba kusuka ku-isiZuluMIPI - MIPIIzinkomba zokuthi izinkomba zezinyawo zokushintsha kufanele ziqashelwe ngamathuba okuhlukanisa ngamathuba. Uma kungenzeka ukwenza izindonga, umbono phakathi kwamathuba okushintsha kufanele kube angaphezu kwemili 15, futhi inhlanganisela yonke igroup kufanele iqashelwe ngomhlaba. Izingxenye zomhlaba kufanele ziqashelwe ngemizuzu ezingama-200 ngamathuba emva kwesicelo. Uma kushintsha izilayi ngezinyawo zokushintsha, kufanele kube nezinyawo zomhlaba ezitholakala ezindaweni ezihlukene. Uma isikhala sifanele, kufanele kwenziwe ukushintsha okushesha kwesinyawo ukuze kwenze ukuthi kungenzeka ukuphazamisa phakathi kwamathuba kanye nokwenza kube nokwenzeka okuhambisana kwesinyawo.

Power Integrity: Decoupling capacitors the camera connection seat's AVDD/DOVDD/DVDD power supplies should be placed as close as possible to the camera connection seat. These capacitors not be omitted to ensure power stability and reduce the impact of power noise on the circuit.

Ukugcina Ukuphathana Kwangaphandle Kwemithetho: Ikhamera kufanele kubekhona kude kwezinto ezinamandla, njengamagama aseGSM, ukuze kungaphansi kwesekelwe. Izinto ezinamandla ezikhanya izimo zangaphandle zangaphandle kanye nezinye ezinamandla ezinamandla kufanele zihlale kude, noma kube khona isicelo sokulondoloza ukulondoloza.

2. Izindlela Zokwenza Okuhlanganisiweyo Zokusetshenziswa.

Ukuzondayo Kwamathuba: Qalisa indawo yezinkampani zokuthuthukisa ngokwesinyathelo sesinyathelo. Qala ngokuziqhenya kwezinkampani zokuthuthukisa, zondaya kuzo ngaphansi, futhi hakikise ukuthi isinyathelo siphilile futhi sifanayo, kuhlanganise kusukela ekunene kuze kube ngasekupheleni noma ekuphamben.

Konke izinto kumele zihlale eceleni eliqondile.IPCB yingxenye yemikhiqizo engenamkhawulo.Ukuze kube yilungiselelo lwewebhu olungcono, uma isihlalo esihle kakhulu, kunezinye izinto ezincane kanye nezincane ezincane ezitholakala phansi. Izinto kufanele zibe nezimo ezithile zokuhlanganisa ukuze kungaphansi kwesithathu noma ukulwa, ukuhlukanisa izikhwama ezifana nokuhlanganiswa okuphakathi kwezinye, ukuphulukisa izikhwama kanye nokuhlanganiswa kwamakhemikhale. Izinto ezitholakala ekugcineni kwezindawo zezikhwama kufanele zibe kude kakhulu kwezinye izikhwama ezimbili.

Ukugcina Nokwakhiwa Kwezidingo Zomsebenzi Womshini: Izinto ezidinga ukugwema kahle kumele ziqashwe kahle futhi izinto ezivamile kumele ziqashwe kahle. Ngokwemvelo yezinto ezivamile njengamapotentiyomitha, amakhaphitoru amaphakathi, amakhaphitoru amavamile, kanye namaswishi amancane, ukulungiswa kwazo kumele kwenziwe ngokwemvelo kwezidingo zomsebenzi. Uma kudinga kuzigcwalelwe ekupheleni komshini, indawo yazo kumele isukelele ekupheleni komuphiqo womshini; uma kudinga kuzigcwalelwe ngaphakathi komshini, kumele ziqashwe endaweni ethandekayo kwi-PCB ukuze kuzigcwalele.

Izindlela Zokufaka Izingxenye.

Izindlela zokwenza: Uma izimo ziyafaneleka, sizaqinisekisa izilayini ezikhulu kunokwesekwa ukuqinisekisa ukuxhuma nokuphazamisa, ngakho kwenza ukulungiswa kwesignali kanye nokushisa kwamakhemikhali. Izilayini zemvoltage eningi kanye nezilayini zemikhumbi ephakeme kumele zibe emhlophe, azikwazi ukwenza izikweletu ezikhali noma izigaba ezikhethekile, ukuze kwenzeke ukuphazamisa kwesignali nokuphazamisa kwamakhemikhali. Izilayini zomhlaba kumele zibe ezikhulu kanjalo noma ngezinye izikhathi ngezinye, ngokuvamile ngezinkambiso ezinkulu zezinkambiso zezinkambiso, ukuze kwenzeke ukulungiswa kwomhlaba nokuthuthukiswa kwesithuthuthu.

Ukusetshenziswa kwezinyathelo ezahlukene, njengamathuluzi/okuphuma, AC/DC, izinyathelo ezinamandla/ezincane, izinyathelo eziningi/ezincane, izinyathelo eziningi/ezincane, noma okunye, kufanele kube kusetyenziswe ngokulandelana futhi ngaphansi kokulungiswa. Indlela enhle kakhulu yokufika kuyona ingu-mlingo omusha.

4. Izimiso Zokubumba Okuyinhloko.

Thwebula: Ukudizayina kwezinkanyezi: Ngokwezinkanyezi ezihlukene, njengamachips amaningi, amathyubhu amaningi, amaresistha, noma okunye, kumele zihlukaniswe ezindaweni ezifanele ukudizayina, futhi uma, ikhasi lokudizayina elihlanzekile noma ifani elikhulu liphathelwe. Uma izinkanyezi zihlukaniswe ezindaweni ezimbili, izinkanyezi ezihlukene zokudizayina kufanele zingaphathelwa ekhishini.

Ukugcina Isolobho: Izinto ezithinta itemperetha kumele zibe sezakhiwo kubantu abathintekile futhi zibe ezindaweni ezikhulu zokushisa ukuze zikwazi ukungathintwa ngamanye amathuluzi okugcina, okwenza kube nokwenzeka okungenakwenzeka.

Ukwenza kanye nezimfihlo zokwenza okungcono nokwengeziweko.

Izindleko Zokwenza: Thinta izinto zokwenza nokwenza kwe-PCB, njengoba i-pakethi yezinto, indlela yokushayela, indawo nokukhulu kwezindawo zokufaka, noma okunye, ukuze uthathe ukuthi ibhodi yecathulo iyakwenza kahle nokwenziwa. idayimitha kanye nokuphakamisa kwamathuba okufaka kufanele kwenziwe ngokwengqondo ukuze kwenzeke ukuphakama okuphakathi.

Ukubeka: Izinto kufanele zibe zihlanganisiwe ngokuzimisela emibhedeni ukuze kungakhishwa ukuphuphuma, ukunqamula okukhulu, kanye nokunzima okunzima, ngakho kuzoba nokuvuselela nokuthuthukisa ukwamukelana kwezinto. Ngokwemibuzo emikhulu noma izinto ezithile ezinamandla okukhushulwa, ukubeka okukhulu noma izinto zokugcina zingasetshenziswa ukuze kuvuselele ukwamukelana kwesistimu.
