Te Hanga PCB Auau-Teitei Paparanga Maha: Ngā Tirohanga Matua mō te Tukanga Whakapiripiri me te Whakahaere Kounga
I te tere o te whanaketanga o ngā hikohiko, kua noho ko ngā PCB auau-teitei maha-paparanga hei mea nui i roto i ngā tono hou pēnei i te whakawhitiwhiti kōrero 5G, te whakatere amiorangi, me ngā pūnaha radar. I te pikinga ake o ngā auau tohu, ka noho te kounga o te tukanga whakapiri hei mea nui hei whakatutuki i te mahi teitei, te pono, me te roa o te ora ratonga.
I roto i tēnei tuhinga, ka tūhuratia e mātou ngā mahi matua o te whakapiri PCB auau-tiketike maha-apa, ka tirohia ngā tikanga hapa noa, ā, ka whakamāramahia ngā tikanga whakahaere kounga whai hua mō ngā putanga hanga PCB pai rawa atu.
Ngā Kaupapa Matua o te Tukanga Whakapiripiri
1. Te Whakarite Rauemi
✔ Kōwhiringa Papa
Ko ngā PCB auau-tiketike e hiahia ana ki ngā rauemi me:
●Te pūmau iti o te hiko (Dk): mō te tere ake o te horapa o te tohu
●Tauwehenga marara iti (Df): hei whakaiti i te ngaronga tohu
Ko ngā papaaho e pai ana ki a rātou ko Rogers me Taconic. Hei tauira, ko ngā PCB teihana turanga 5G e whakamahi ana i ngā papaaho me ngā uara Dk i waenga i te 3.0–3.5, kia rite ai te mahi puta noa i ngā hongere raraunga tere-tiketike.
✔ Ngā Āhuatanga o te Pepa Parahi
●He iti te taratara o te mata: ka whakaiti i te ngaronga o te ara iahiko
●Teitei te parakore: ka iti ake te ātete me te pai ake o te tuku tohu
Ngā taumaha parahi noa: 1/2 auneke, 1/4 auneke rānei o te parahi hikohiko, he mea tino pai mō te mahi RF.
✔ Hototahi ki te Prepreg (PP)
Ko ngā Prepregs te paparanga piri i roto i te whakakī. Ko ngā mea matua ko:
●Te nui me te rere o te kapia: me ōrite ki te rauemi turanga me te pepa parahi
●Ka whakamahia ngā momo prepreg rerekē i runga i te matotoru o te PCB me te maha o ngā paparanga. Mā te whiriwhiri tika i te prepreg ka kaha te piri o ngā paparanga me te mahi hiko.
2. Te Hanganga o te Paparanga o Roto
✔ Whakaahua me te Whakairo Tino Tika
●Me eke te tika o te whakaaturanga photoresist ki te taumata micron
●He mea nui te ōritetanga o te whakairo hei pupuri i te whānui o te rārangi/te ātete ki te wāhi (hei tauira, 50μm/50μm)
✔ Tirotiro Paparanga o Roto
Mā te tātaritanga i muri i te whakairo, te tirotiro pakari mā te whakamahi i te AOI (Automated Optical Inspection) me te whakamātautau i ngā pūwero rere ka kore he hapa o ngā ara iahiko. Ahakoa ngā poto iti, ngā whakatuwheratanga rānei, ka raru pea ngā hoahoa auau teitei i muri i te whakakikoruatanga.
3. Te Whakatinanatanga o te Whakakī
✔ Whakapiringa-Mua (Pēhi-Mua)
Whāinga: te pana i te hau kua mau me ngā mea whakakorikori
●Pāmahana: 60–80°C
●Pēhanga: 1–2 MPa
●Wā: 5–10 meneti
Mā te pēhi-mua ka piri te paparanga tuatahi, ā, ka papatahi hoki ngā paparanga rauemi mō ngā hua whakapiri tino pai.
✔ Whakapiripiri Pēhi Wera
Te tukanga matua e rere ai, e whakamaroke ai hoki te kapia prepreg:
●Pāmahana: 180–220°C
●Pēhanga: 5–10 MPa
●Wā: 30–60 meneti
●Te ōritetanga o te pāmahana o te pereti wera: He mea nui te ±2°C hei karo i te kore taurite o te whakaora o te kapia
Me whakakī ōrite te kapia i ngā āputa i waenga i ngā paparanga kia kaha ai te piri, kia kore ai hoki e puta he āputa.
✔ Whakamatao Whakahaeretia
●Te tere whakamatao pai rawa atu: 1–3°C/min
●Ārai i te ahotea ā-roto me te piko
Mā te whakamatao āta ka taea te whakamamae i te ahotea ā-ringa, kia mau ai te pumau me te papatahi o ngā āhuatanga.
