Pepa Ma Mana Kounga PCB Auau-Teitei
Ngā Tirohanga o te Raina Mua: Te Tūranga Hiranga o te Whakahaere Kounga i te Ao o ngā PCB Auau-Teitei
Ko ngā papa hiko tānga auau-teitei (PCB) o ēnei rā te pūtake hangarau mō te maha o ngā pūnaha hiko matatau. Mai i te whakaroa tino-iti i roto i te whakawhitiwhiti kōrero 5G me te tūnga tika i roto i te whakatere amiorangi, ki te tukatuka tohu radar i roto i ngā taiao hikohiko uaua me te rorohiko mahi-teitei, he mea tino nui te pono me te tika o ngā PCB auau-teitei.
He mea nui te mōhio ki ngā āhuatanga uaua o te whakahaere kounga PCB auau-tiketike mō ngā tohunga kounga me ngā kaihangarau. Mā tēnei pepa mā ka ruku hohonu ki ia wāhanga o te whakapūmau kounga—mai i te hoahoa ki te whakaputa—ā, ka whakamāramahia hoki ngā rautaki hei whakatutuki i ngā paerewa mahi e piki haere ana te tono o ngā tono o te whakatupuranga e whai ake nei.
Hoahoa: Te Pūtake o te Kounga
Tahora Porowhita: He mea nui te Tika
I roto i ngā ara iahiko auau-teitei, ko te pono o te tohu e whakawhirinaki ana ki te whakahaere ātete tino tika. Hei tauira, he mea nui te pupuri i te ātete āhuatanga i roto i te ±5% (te tikanga 50Ω, 75Ω rānei), inā koa i roto i Ngā PCB teihana turanga 5GMā ngā pekapeka iti, pērā i te kore ōrite o te 0.1Ω i ngā auau mirimita-ngaru (24–52GHz), ka arahi pea ki te whakaata nui, te whakaiti i te tohu, me te pikinga ake o ngā reiti hapa moka.
Hei whakaiti i tēnei, ka whakawhirinaki ngā kaihoahoa ki ngā pūmanawa whakaata hikohiko matatau hei arotau i te whānui o te rārangi, te mokowā, te matotoru o te dielectric, me te pūmau dielectric (Dk). I roto i ēnei taiao auau-tiketike, ahakoa ngā rerekētanga o te whakatakotoranga moroiti ka taea te whakararu i te mahi.
Hei tāpiritanga, me āta whakahaere te āhua o te ara:
● Ka nui ake te roa o te tohu ka whakaroa, ka ngaro hoki.
● Ka whakapiki ake ngā tohu whaiti i te ātete.
● Ka puta te whakawhitiwhiti kōrero nā ngā whakatakotoranga matotoru, ā, me noho tonu ki raro iho:
● Whakawhitiwhiti Tata-Mutu (NEXT): -30dB
● Whakawhitiwhiti Kōrero Tawhiti (FEXT): -40dB
Mō ngā atanga tere-tiketike pēnei i te USB 3.0, HDMI rānei, me mau tonu te tika o te roa o te ara iahiko takirua rerekē ki te ±5mil kia mau ai te pono o te tohu.
Hoahoa Whakatakotoranga: Te Whakataurite i te Ahupūngao me te Āhuatanga Hanga
Ko ngā PCB auau-teitei o ēnei rā, inā koa i roto i te whakawhitiwhiti kōrero me te rererangi, he maha ngā wā ka neke atu i te 10 ngā paparanga. E hiahiatia ana e ēnei hoahoa he iti te Dk me te iti te Df, pērā i a Rogers RO4350B, hei whakaiti i te ngaronga tohu me te pupuri i te tere raraunga. Heoi, he nui ake ngā utu me te uaua o te tukatuka i ēnei rauemi.
Ko ngā tawhā matua ko:
● Te tika o te rēhitatanga i waenga i ngā paparanga: me noho i roto i te ±50μm hei karo i te he o te tūnga, te poto rānei.
● Ngā tikanga whakarārangi:
● Te pāmahana: 180–220°C
● Pēhanga: 5–10MPa
● Wā: 30–60 meneti
Me mahi tahi tata ngā tīma hangarau me ngā tīma whakaputa kia whakarite kia ōrite ngā hoahoa tāpae ki ngā āheinga whakapiri a te kaihanga.
Te Hanga: Mai i ngā Rauemi ki te Mahi Matua
Te Mana o ngā Rauemi Mata: Te Kounga mai i te Pūtake
He mea nui te pūnaha tirotiro kounga hou pakari. Hei tauira:
● Te rerekētanga Dk: ≤ ±0.1
● Df (pānga ngaronga): ● Te ātete matotoru: he tino whakahaeretia
● Ngā hapa tirohanga: me karohia ngā mirumiru, ngā wehewehenga, me ngā karawarawa
He nui hoki te pānga o te parakore o te pepa parahi me te nui o te kapia prepreg ki te mahi. Mā te parahi parakore teitei ka iti te ātete, ā, mā te rere tika o te kapia ka kaha te hononga i waenga i ngā paparanga. Mā te tauira me te whakamātautau i ia wā ka āwhina i te pupuri i te hanganga o ngā rauemi ki ngā paerewa RF-grade.
Te Mana Kounga Tukanga: Te Tika o Ngā Taipitopito Katoa
Te whakairo:
● Te ātete whānui o te rārangi: ±0.05mm
● Te ōritetanga o te whakairo: Mā te kore whakahaere pai ka iti te tapahi, ka nui rawa rānei te whakairo, ka whakararu i te pumau o te ara iahiko.
Te keri:
● Te tika o te tūnga o te kōhao: ±0.1mm
● Te ātete ki te whānui o te kōhao: ±0.02mm
Mā te horoi i muri i te keri ka tangohia ngā paru hei ārai i ngā poto poto. Mā te whakakikorua parahi o ngā vias ka whakarite te kawe hiko me te pono.
Te whakakikorua hiko:
● Te matotoru o te whakakikorua mata: 1–3μm
● Mā te whakakikorua pakitara: 0.5–1.5μm
Mā te whakahaere tika i te matū o te otinga me te mātotoru o te iahiko ka ārai i ngā raruraru pēnei i te āputa, te mirumiru, te wehewehe rānei, kia pai ai te mahi mō te wā roa.
Te Tātaritanga o te Rahunga me ngā Mahi Ārai
Ngā Raru Hiko: Ngā Kaiwhakamate Mumu o te Pono o te Tohu
Ngā Tohu: te ngoikore, te whakapōturi, te nui rawa o te whakawhitiwhiti kōrero, me te hekenga o te āhua o te ngaru
Ngā Take:
● Te kore taurite o te ātete

● Te whakataurite i ngā CTE rauemi i roto i te puranga
● Ngā mana whakahaere taiao pakari i te wā whakaputa
Te Paerewa Ahumahi: Ko te Kounga hei Rerekētanga
Ko ngā hua o ngā kaihanga o te taumata teitei ko:
● Ngā taputapu hoahoa PCB e hangai ana ki te AI
● Aunoatanga tukanga matatau
● Ngā pūnaha tirotiro whānui
E tutuki ana ā rātou hua i ngā paerewa pakari mō te 5G, te rererangi, me te whakawhitiwhiti kōrero amiorangi, e whakamanamana ana ki ngā reiti hua teitei me te pono kāore e taea te whakataurite. He rerekē, he maha ngā wā kāore i te matatau ngā kaihanga kāore i te matatau ki te hoahoa matatau, ki te whakahaere rauemi, me te kaha tirotiro, ka nui ake ngā reiti hapa me te iti o te whakataetae.
He aha te Harikoa Nui?
Kua whakatūria e Rich Full Joy tētahi ingoa pakari i roto i te umanga papa hiko RF me te papa hiko auau-teitei me:
