Ngokuthuthuka okusheshayo kwemboni yezogesi, amabhodi e-PCB abe yingxenye ebalulekile yemishini ehlukahlukene ye-elekthronikhi. Noma ngabe kuma-electronics abathengi, izinto zikagesi zezimoto, noma kwezokwelapha, izimboni neminye imikhakha, ukusetshenziswa kwama-PCB kubaluleke kakhulu. Amabhodi e-PCB Ukwenza ngendlela oyifisayo nokukhiqizwa ngobuningi kubalulekile ekuqinisekiseni ukusebenza komkhiqizo kanye nekhwalithi. Ngakho-ke, masifunde mayelana nezinyathelo zokuphepha zokwenza ngokwezifiso ibhodi le-PCB nokukhiqizwa ngobuningi.
一、Ukulungiselela okuphelele ngaphambi kokuklama
Ngaphambi kokwenza ngokwezifiso kanye nokukhiqizwa kwamabhodi e-PCB, ukuklama okwanele nokuhlela kuyizinyathelo ezibalulekile. Abaklami badinga ukucacisa inhloso yebhodi lesifunda, izinhlobo zezingxenye ze-elekthronikhi okudingeka zithwalwe, kanye namazinga okusebenza alindelekile. Ucwaningo lwemakethe ngaphambi kokuklama lubaluleke kakhulu. Kungasiza abaklami baqonde ubuchwepheshe obusha, izinto ezintsha nezinqubo ezintsha emakethe ukuze kuhlangatshezwane kangcono nezimfuneko zokusebenza komkhiqizo nokulawulwa kwezindleko.
二 、 Khetha into efanele
Ukusebenza kwebhodi le-PCB kuncike kakhulu ezintweni eziyisisekelo ezikhethiwe kanye nempahla ye-copper clad laminate. Izinto eziyisisekelo ezijwayelekile zifaka i-FR-4, i-CEM-1, njll. Izici zikagesi kanye nezakhiwo ezibonakalayo zezinto ezahlukahlukene zihlukile, ngakho-ke kufanele ucabangele izinga lokushisa lendawo kanye nezimo zomswakama, izidingo zokusebenza kukagesi, nesabelomali sezindleko eziphezulu, izinhlelo zokusebenza zemvamisa, izinto ezisezingeni eliphakeme ezine-dielectric engaguquki kanye nokulahleka okuphansi kufanele kukhethwe ukuze kuncishiswe ukulahlekelwa ngesikhathi sokudlulisa isignali.
三、Ukubekwa okunembile kanye nomzila
Abaklami kufanele bagweme imigqa yesignali yesivinini esikhulu abade kakhulu noma abaphambanayo ukuze banciphise ukuphazamiseka kwesignali nokubambezeleka kokudlulisela. Isakhiwo sokuphakelwa kukagesi nezintambo zaphansi kufanele futhi kuhlelwe ngokunengqondo ukuze kuqinisekiswe ukuhlinzekwa kwamandla wesekethe ezinzile futhi kugwenywe umsindo ongase ube khona wokuphakelwa kukagesi. Phakathi nenqubo yokuklama, isofthiwe yokuklama ye-PCB echwepheshile, efana ne-Altium Designer, i-Cadence, njll., kufanele isetshenziselwe ukuzuza ukunemba okuphezulu kwesakhiwo kanye nezintambo.
四、Ukuhlolwa kwe-Prototype nokuqinisekisa
Ngaphambi kokukhiqiza ngobuningi, ukwenza nokuhlola ukuqinisekisa kwe-PCB kuyisinyathelo esibalulekile sokuqinisekisa ukusebenza kahle komklamo. Ngokuqinisekisa nokuhlola, izinkinga ekwakhiweni zingatholwa futhi zilungiswe ngesikhathi, njengokuhlela okungenangqondo kwezinye izingxenye kanye nobubanzi bomugqa obanele.
五、Khetha uzakwethu olungile wokukhiqiza
Izinga lokukhiqiza ngobuningi lamabhodi e-PCB lincike kakhulu ezingeni lobuchwepheshe namandla okukhiqiza womkhiqizi. I-Shenzhen Fastline PCB Company ingumkhiqizi we-PCB onolwazi ngemishini yokukhiqiza ethuthukisiwe. Lapho ukhetha umlingani, ngaphezu kokucabangela izindleko zekhotheshini nokukhiqiza, kufanele futhi unake uhlelo lwayo lokulawula ikhwalithi, isikhathi sokulethwa kanye nesevisi yangemuva kokuthengisa.
六、Ukuqapha izinga kanye nokwenza ngcono
Enqubweni yokukhiqiza ngobuningi be-PCB, ukuqaliswa kokuqapha kwekhwalithi okuqhubekayo kuyisinyathelo esibalulekile sokuqinisekisa ukuvumelana komkhiqizo, okuhlanganisa ukuqapha okuqinile kwazo zonke izixhumanisi emugqeni wokukhiqiza, njengokuhlola impahla eluhlaza, ukulawula inqubo yokukhiqiza, ukuhlolwa komkhiqizo wokugcina, njll. , kanye nenqubo yokukhiqiza Ukwenza ukuhlaziya imbangela yezimpande zezinkinga ezitholakala kunqubo kanye nokwenza ngcono inqubo yokukhiqiza ngokufanele kuyindlela ephumelelayo yokuthuthukisa ngokuqhubekayo ikhwalithi yomkhiqizo.
Ukwenziwa ngokwezifiso kanye nokukhiqizwa okukhulu kwamabhodi e-PCB kuyinqubo eyinkimbinkimbi ehlanganisa ukucatshangelwa okuningi. Kusukela ekukhethweni kwezinto ezibonakalayo, ukwenziwa ngcono kwedizayini kuye ekukhethweni kozakwethu bokukhiqiza, sonke isixhumanisi sidinga ukuhlela ngokucophelela nokwenza. Ngezinyathelo zokuqapha okukhulunywe ngazo ngokuningiliziwe ngenhla, sithemba ukusiza izinkampani nabaklami abafanelekile bathuthukise ukusebenza kahle kokukhiqiza, ukunciphisa izindleko, futhi ekugcineni bazuze umkhiqizo wekhwalithi ephezulu.
