Iphaneli ye-PCBimithetho nezindlela
1. Ngokwezidingo zenqubo yamafekthri ahlukene ahlanganisayo, ubukhulu bobukhulu kanye nosayizi omncane wephaneli kufanele kuqondwe ngokucacile.Ngokuvamile, i-PCB encane kuno-80X80mm idinga ukufakwa ngamaphaneli, futhi usayizi omkhulu uncike kumthamo wokucubungula wefekthri.Ngamafuphi, usayizi we-pcb kufanele uhlangabezane nemfuneko yeImishini ye-SMTokokufaka, okulungele ukucutshungulwa kwesichibi se-SMT nokusiza ukunquma ukujiya kwebhodi le-PCB.
2. Ukuhlanganisa kanye ne-sub-boarding kufanele kuhlangabezane nezidingo ze-DFM ne-DFA, futhi ngesikhathi esifanayo kuqinisekiswe ukuthi umhlangano we-PCB ulungisiwe futhi awugugi kalula ngemva kokubekwa endaweni.I-groove ehlukanisayo phakathi kwamaphaneli kufanele ihlangabezane nezidingo zokulala kwendawo ngesikhathiPCBAukucutshungulwa kwe-chip.
3. Kuphaneli ye-PCBumklamo, ukuhlelwa kwezingxenye kufanele kugweme ukuhlukanisa ukucindezeleka futhi kubangele ukuqhekeka kwengxenye.Ukusetshenziswa kwesakhiwo sephaneli efakwe ngaphambilini kunganciphisa i-warpage kanye nokuguqulwa ngesikhathi sokuhlukaniswa kwebhodi, futhi kunciphise ingcindezi ezingxenyeni.Okungenani, zama ukungabeki okubalulekileizingxenyeOlandelayoohlangothini lwenqubo.
4. Usayizi kanye nefomu lephaneli liphathwa ngokuvumelana nephrojekthi ethile, futhi umklamo wokubukeka useduze nesikwele ngangokunokwenzeka.Kunconywa kakhulu ukusebenzisa indlela yephaneli engu-2×2 noma engu-3×3.Akunconywa ukuhlanganisa amaphaneli e-yin ne-yang uma kungenasidingo;
5. Uma uhlaka lwesixhumi sonqenqema lwebhodi ludlula ukuphazamiseka phakathi kwamabhodi ahlangene amaningi, luxazululwa ngokuzungezisa uhlangothi lwenqubo oluhlangene + ukuze kuvinjelwe izinga elibi lomonakalo wokungqubuzana phakathi nenqubo yokudlulisela noma yokusingatha.ngemva kokushisela.
6. Ngemuva komklamo wephaneli, kufanele kuqinisekiswe ukuthi unqenqema lwephoyinti lesithenjwa lebhodi elikhulu likude okungenani no-3.5mm ukusuka onqenqemeni lwebhodi (ububanzi obuncane bomshini obamba unqenqema lwe-PCB ngu-3.5mm ), futhi amaphuzu amabili ereferensi ediagonal ebhodini elikhulu awakwazi ukubekwa ngokulinganayo.Ungawabeki amaphoyinti ereferensi ngokulinganayo, ukuze uhlangothi oluhlehlayo/oluhlehlayo lwe-PCB lukwazi ukungena emshinini ngomsebenzi wokuhlonza wedivayisi ngokwayo.
7. Lapho ukushuba kweIbhodi le-PCBingaphansi kuka-1.0mm, amandla ebhodi lephaneli lonke azoncishiswa kakhulu (abe buthakathaka) lapho i-splicing joint noma i-v-cut groove yengezwa, ngoba ukujula kwe-V-cut kuyi-1/3 yobukhulu bebhodi, ibhodi le-PCB lisetshenziselwa amandla, futhi ingxenye yohlaka lwamathambo asekelayo - indwangu ye-fiber yengilazi engu-V iphukile, okuholela ekuthambeni okuphawulekayo kwamandla.Uma ingasekelwe i-jig, izothinta inqubo engezansi kwe-PCBA.
8. Lapho kukhonaiminwe yegolideku-PCB, ngokuvamile beka iminwe yegolide ngaphandle kwebhodi lapho ibheke khona lapho okunganqamuki khona.Unqenqema lomunwe wegolide awukwazi ukuhlukaniswa noma ukucutshungulwa.
