Te Rerekētanga i waenga i ngā PCB Uku me ngā PCB FR4 Tuku Iho
I mua i te matapaki i tēnei take, me mārama tātou he aha ngā PCB uku me ngā PCB FR4.
Ko te Papa Arahiko Uku e pā ana ki tētahi momo papa arahiko i hangaia i runga i ngā rauemi uku, e mōhiotia ana ko te PCB Uku (papa arahiko tānga). He rerekē ki ngā papa kirihou whakakaha muka karāhe noa (FR-4), ka whakamahia e ngā papa arahiko uku ngā papa uku, ka taea te whakarato i te pumau pāmahana teitei ake, te kaha miihini pai ake, ngā āhuatanga dielectric pai ake, me te roa ake o te ora. Ko ngā PCB uku te nuinga o te wā e whakamahia ana i roto i ngā arahiko pāmahana teitei, auau teitei, me te mana teitei, pērā i ngā rama LED, ngā whakakaha mana, ngā taiaho semiconductor, ngā transceivers RF, ngā pūoko, me ngā taputapu ngaruiti.
Ko te Papa Arahiko he rauemi taketake mō ngā wāhanga hiko, e mōhiotia ana ko te PCB, ko te papa arahiko tānga rānei. He kaikawe mō te huihui i ngā wāhanga hiko mā te tā i ngā tauira arahiko whakarewa ki runga i ngā papa kore-arahiko, kātahi ka hanga ara hiko mā roto i ngā tukanga pēnei i te waikura matū, te parahi hikohiko, me te keri.
Kei raro nei tētahi whakataurite i waenga i te uku CCL me te FR4 CCL, tae atu ki ō rāua rerekētanga, ngā painga me ngā ngoikoretanga.
