Imibuzo Evame Ukubuzwa
Iyiphi inzuzo enkulu yokusebenzisa izinto ezithuthukisiwe njenge-LCP ekwakhiweni kwe-PCB?
Uthola ukumelana nokushisa okungcono futhi ukuvikela umswakama nge-LCP. Lokhu okuqukethwe kusiza ibhodi lakho ukuthi lihlale isikhathi eside futhi lisebenze kahle ezindaweni ezinzima.
Uyivimbela kanjani i-warpage kumabhodi we-multilayer?
Kufanele uhambisane namazinga okunwebeka okushisayo kwezinto zakho. Sebenzisa amathuluzi okulingisa ukuze uhlole isitaki sakho ngaphambi kokukhiqiza. Lesi sinyathelo sikusiza ukuthi ugweme ukugoba noma ukusonteka.
Ungakwazi yini ukuhlanganisa i-FR-4 ejwayelekile nezinto ezisetshenziswa yimvamisa ephezulu ebhodini elilodwa?
Yebo, ungahlanganisa i-FR-4 ne high-frequency materials. Le ndlela ikuvumela ukuthi ulinganisele izindleko nokusebenza. Beka izinto zefrikhwensi ephezulu kuphela lapho uzidinga khona.
Kungani ukubambisana komkhiqizi kubalulekile kumaphrojekthi ayinkimbinkimbi e-PCB?
Uthola iseluleko sochwepheshe mayelana nokukhetha okubalulekile kanye nezinyathelo zokucubungula. Izingxoxo zangaphambi kwesikhathi zikusiza ukuthi ugweme amaphutha futhi uthuthukise ukwethembeka kwebhodi lakho.
