Kupu Whakataki: Mai i ngā Hononga ki ngā Wero Taumata-Micron
I te tere haere o te whakawhitiwhiti kōrero 5G, ngā tūmau AI, mengā hangarau tākai matatau,Kua whanake te hanga PCB (Papa Porowhita Tā) hei tūāpapa kiato-teitei, e whakahaerehia ana e te microvia. Ko te tango i ngā papa HDI, ngā PCB paparanga maha, me ngā IC Substrates e tohu ana i te whakawhiti ki te wā hanga tauine-micron, e whai wāhi nui ana te keri mā te hanga hononga hiko pono i waenga i ngā paparanga (Via Interconnects). Heoi, i te mea ka heke te diameter keri i raro i te 0.2 mm, tae atu ki te 0.1 mm, kua kore e taea e ngā huarahi miihini tuku iho te whakatutuki i ngā hiahia o ngā rauemi auau-teitei me te hanga tino-tika, ka waiho te kakahu taputapu, te pakaru o te keri moroiti, me te kounga o te pakitara poka kore pumau hei wero nui ki te hua PCB me te rite o te hanga.
Ngā Wero Tukatuka i roto i te Keri Microvia
I roto i te hanga PCB kiato-teitei, he tukanga tino tairongo te keri moroiti e whakahaerehia ana e te āhua o te taputapu, te whanonga rauemi, me te kaha tapahi. I ngā tere porowhita tino teitei, e tae ana ki ngā tekau mano ki ngā rau mano RPM, ko te iti rawa o te mata tapahi o ngā keri moroiti ka tino pāngia e ngā pānga wera, ka tere ake te kakahu o te taputapu, ka whakanui ake i te tauwehenga o te waku, ka arahi ki ngā āhuatanga tapahi kore pumau. I te hekenga o te mata tapahi, ka huri te tango rauemi ki te whakarerekētanga me te haehae, ka hua ake he taratara o te pakitara kōhao, te hanganga o te maripi, me te piri o te kapia, ka kohia katoatia ēnei puta noa i ngā rarangi microvia matotoru ka whakaiti nui i te pumau o te tukanga.
Ka nui ake te kitea o tēnei take ina whakamahia ngā papaaho auau-teitei matatau pērā i te PTFE, te kapia BT, me ngā rauemi ABF, ina iti te modulus me ngā āhuatanga piri teitei ka whakatairanga i te paninga kapia (Smear) me ngā pānga wicking (Wicking) i ngā pakitara via. Ka whakapohehe ēnei hapa i te āhua o te via, ka whakararu i te tika o ngā āhuatanga, ā, ka pā kino ki ngā tukanga o raro tae atu ki te whakakoi me te pono o te whakakikorua hiko, ka tū hei mōrearea nui mō ngā tono teitei pērā i ngā Papaaho IC, ina tino iti te manawanui ki ngā hapa.
Kōwhiringa Hangarau Mata me te Hangarau Paninga
Hei whakapai ake i te mahi keri moroiti, he mea nui te hangarau mata mā roto i ngā hangarau paninga matatau. Ahakoa ka taea e te paninga kore-hiko me te CVD (Chemical Vapor Deposition) te whakanui ake i te pakeke o te mata ki tētahi taumata, he herenga kei roto i ngā tono moroiti, tae atu ki te koretake o te matotoru o te paninga, te pāmahana whakatakotoranga teitei, te kino pea o te papa, me te ahotea toenga teitei e arahi ana ki te wehenga o te paninga i raro i ngā tikanga miihini tere-teitei.
He rerekē, ko te Hangarau Paninga Korehau PVD (Physical Vapor Deposition) he otinga pai ake mō ngā mahi keri moroiti, nā te mea ka taea te whakatakotoranga i ngā kiriata angiangi matotoru, ōrite i te pāmahana iti me te piri pai, te whakaiti i te tauwehenga waku, me te whakapakari ake i te ātete kakahu, e whai hua ana ki te whakau i te tukanga tapahi me te whakaiti i te paninga kapia me te whakapai ake i te pumau o te pakitara poka.
Otinga Paninga Wiri Moroiti Korehau Zhenhua
Ko te Pūnaha Paninga PVD MFA0605 he mea hanga motuhake mō ngā tono paninga taputapu mahi-teitei i roto i te umanga PCB. He pūnaha tātari whakakikorua āwhata i whakawhanakehia e ia anō, ka whakakorea paitia ngā matūriki nui i puta i te wā whakatakotoranga, ka whakarite i te kounga kiriata pai me te ōritetanga o te paninga. Ka tautokohia e te pūnaha ngā paninga Ta-C matatau (waro kore-āhua tetrahedral), e tuku ana i te pakeke tino-teitei tae atu ki te 63 GPa, me te tauwehenga waku iti, te ātete waikura pai rawa atu, me te roa ake o te ora o te taputapu. I taua wā anō, ka taea e ia te whakatakotoranga i te whānuitanga o ngā paninga mahi-teitei pēnei i te AlTiN, AlCrN, TiCrAlN, TiAlSiN, me te CrN, ka tino urutau mō ngā wiri moroiti PCB, ngā taputapu tapahi, ngā pokepokea tika, me ngā wāhanga motuka, me te pupuri tonu i te piri paninga pumau, te ōritetanga puranga pai rawa atu, me te mahi whakatakotoranga kiriata angiangi tino pai i roto i ngā taiao whakaputa papatipu.
Whakamutunga
I te haere tonu o te hanga PCB ki te ahu whakamua ki te kiato teitei ake, ki ngā vias iti ake, me ngā hanganga uaua ake, kua noho te kaha keri moroiti hei mea matua mō te kounga whakaputa me te whakataetae. I roto i tēnei horopaki, ehara te paninga taputapu i te whakarei ake tāpiri engari he hangarau whakahohe nui e whakatau tika ana i te roa o te ora o te taputapu, te kounga o te kōhao, me te pumau o te tukanga whānui. Mā te whakamahi i te Hangarau Paninga Korehau PVD, ka whakapai tonu a Zhenhua Vacuum i te ōritetanga o te paninga, te pumau o te kiriata, me te ōritetanga o te whakaputanga, ka taea ai te mahi pono i roto i ngā rauemi auau teitei me te keri microvia tino pai.
