Ko te rerekētanga matua i waenga i te HDI me te PCB noa - he wā hou o te hononga honohono-teitei
He papa hiko iti te HDI (High Density Interconnection) i hangaia mō ngā kaiwhakamahi iti te rahinga. Ki te whakatauritea ki ngā PCB noa, ko te āhuatanga nui o te HDI ko tōna matotoru waea teitei. Ko te rerekētanga i waenga i ngā mea e rua e kitea nuitia ana i roto i ngā āhuatanga e whā e whai ake nei.
1. He iti ake te HDI, he mama ake hoki te taumaha
He mea hanga ngā papa HDI i ngā papa taha-rua tuku iho hei papa matua, ā, ka pania ki te whakapiripiri tonu. Ko tēnei momo papa hiko i hangaia ki te whakapiripiri tonu ka kiia hoki he papa paparanga maha-papa (BUM). Ki te whakatauritea ki ngā papa hiko tuku iho, he "māmā, he angiangi, he poto, he iti" ngā painga o ngā HDI.
Ko te hononga hiko i waenga i ngā paparanga papa HDI ka whakatinanahia mā roto i ngā hononga whakawhiti-pūwero, he mea huna/matapō. He rerekē tōna hanganga i ngā papa ara iahiko maha-paparanga noa. He maha ngā ara iahiko huna-pūwero/matapō e whakamahia ana i roto i ngā papa HDI. Ka whakamahia e te HDI te keri tika i te laser, ko te PCB paerewa ia ka whakamahia te keri miihini, nō reira ka whakaitihia te maha o ngā paparanga me te ōwehenga āhua.
2. Tukanga whakaputa papahoahoa HDI
Ko te matotoru o ngā papa HDI e kitea nuitia ana i roto i te matotoru o ngā kōhao, ngā rārangi, ngā papa, me te matotoru o ngā paparanga.
Pūwero-iti: Kei roto i te papa HDI ngā hoahoa pūwero-iti pērā i te pūwero matapo, e whakaatahia ana i roto i te hangarau hanga pūwero-iti me te diameter iti iho i te 150um me ngā whakaritenga teitei e pā ana ki te utu, te whai huatanga o te whakaputa me te whakahaere tika o te tūnga pūwero. He pūwero anake kei roto i ngā papa hiko maha-apa tuku iho, ā, kāore he pūwero huna/matapo iti.
Te whakapai ake i te whānui/mokowā o te rārangi: Ko te nuinga o tēnei e kitea ana i roto i ngā whakaritenga e piki haere ana te kaha mō ngā hapa rārangi me te taratara o te mata rārangi. I te nuinga o te wā, kaua te whānui/mokowā o te rārangi e neke ake i te 76.2um.
Teitei o te mātotoru o te papa: he nui ake te mātotoru o te whakapā whakapiri i te 50/cm2
Te angiangi o te matotoru o te dielectric: Ko te nuinga o tēnei e whakaatahia ana i roto i te ia o te matotoru o te dielectric i waenga i ngā paparanga ki te 80um me raro iho, ā, kei te kaha haere ngā whakaritenga mō te ōritetanga o te matotoru, inā koa mō ngā papa matotoru me ngā papa takai me te mana whakahaere ātete āhuatanga.
3. He pai ake te mahi hiko o te papa HDI
Ehara i te mea ka taea e te HDI te whakaiti i ngā hoahoa hua whakamutunga, engari ka tutuki hoki i ngā paerewa teitei ake mō te mahi hiko me te whai huatanga.
Mā te nui haere o te mātotoru hononga o te HDI ka taea te whakanui ake i te kaha o te tohu, ā, ka pai ake hoki te pono. Hei tāpiri, he pai ake ngā whakapainga o ngā papa HDI ki te pokanoa RF, te pokanoa ngaru hikohiko, te tukunga hiko, te kawe wera, me ētahi atu. Ka whakamahia hoki e te HDI te hangarau whakahaere tukanga tohu matihiko katoa (DSP) me te maha o ngā hangarau patent, me te urutau kawenga whānui me te kaha kaha ki te utaina i te wā poto.
4. He tino teitei ngā whakaritenga mō ngā papa HDI kia tanumia mā te mono.
Ahakoa te rahi o te papa, te mahi hiko rānei, he pai ake te HDI i te PCB noa. E rua ngā taha o ia moni. Ko tētahi atu taha o te HDI, nā te mea he PCB kounga teitei te hanga, he nui ake tōna paepae hanga me te uauatanga o te tukanga i ērā o ngā PCB noa. He maha anō hoki ngā take me aro atu ki te wā whakaputa - inā koa ko te mea kua tanumia mā te mono.
I tēnei wā, ko te tino uauatanga me te uauatanga o te hanga HDI kei roto i te mono. Mēnā kāore te HDI i tanumia mā te mono tika, ka puta he raruraru kounga nui, tae atu ki ngā taha papa kāore i te ōrite, te matotoru kore-hiko, me ngā papa kua pakaru, me ētahi atu.
He koretake te mata o te papa, ā, kāore ngā rārangi i te tika, ka puta te āhuatanga takutai moana i ngā rua hohonu, ka ara ake pea ētahi hapa pērā i te āputa rārangi me te momotu.
Ka rerekē anō hoki te ātete āhuatanga nā te matotoru koretake o te dielectric, ka kore e pumau te tohu.
Nā te kore taurite o te papa whakapiri ka hua ake he kounga iti o ngā takai, ā, ka ngaro pea ngā wāhanga.
Nō reira, kāore i te katoa o ngā kaihanga PCB he kaha, he kaha hoki ki te mahi pai i te HDI. Neke atu i te 20 tau o te wheako ki te hanga PCB, ka whakaratohia e RICHPCBA ngā hangarau hanga papa ara iahiko tā hou me ngā paerewa kounga teitei mō te umanga hikohiko.
