Rārangi Arowhai mō ngā Tāpui Hoahoa PCB Auau-Teitei

I te ao matihiko tere-teitei o ēnei rā, ko ngā papa hiko tānga auau-teitei (PCB) te pou tuarā o ngā hangarau matatau pēnei i te whakawhitiwhiti kōrero 5G, te whakatere amiorangi, ngā pūnaha radar, te rorohiko mahi-teitei, me ngā hiko kaihoko kounga teitei. Ka pā tika te kounga o te hoahoa PCB auau-teitei ki te pumau, te whai huatanga, me te pono o te pūnaha hiko katoa.

Mō ngā kaihanga hoahoa PCB, he mea nui te mōhio ki ngā mātāpono hoahoa PCB RF me te karo i ngā hapa hoahoa nui. Ka rukuhia e tēnei tuhinga ngā tapu hoahoa PCB auau-tiketike e tino kitea ana, ka whakamāramahia ngā take me ngā pānga o aua mea, ā, ka whakamāramahia ngā rerekētanga kaha i waenga i ngā hoahoa taumata-teitei me ngā hoahoa mahi-iti.

1, Ngā Taputapu Hoahoa Ara

✕ Te Whakahāwea i te Taurite Āhuatanga Ārai

Ko te tuku tohu i roto i ngā PCB auau-tiketike e hiahia ana kia tino kaha te whakahaere i te aukati, i roto i te ±5% o ngā uara ūnga pēnei i te 50Ω, 75Ω rānei. Ki te kore e whakaarohia te whānui o te tohu, te mokowā, te matotoru o te dielectric, me te rauemi Dk, ka puta te motumotu o te aukati, ka hua ake:

● Whakaata tohu
● Te whakapōturitanga o te āhua ngaru
● Te pikinga o te tere hapa moka
● Te whakaiti nui o te tohu
Hei tauira, i roto i ngā teihana turanga 5G, ka hua ake te kore taurite o te aukati i te ngaronga o ngā pākete raraunga, te ngoikore o te hononga, me te ngoikore o te wheako kaiwhakamahi. Whakamahia ngā taputapu whakatauira hikohiko hei tatau tika i te aukati, ā, whakaarohia tonutia ngā manawanui hanga me ngā whakawhirinakitanga whakapūtātanga.

✕ Te Āhua o te Ara Kino

Mā ngā whakataunga ara hē—pērā i ngā tohu roa rawa, whaiti rawa, piri rawa rānei—ka puta:

● Te whakaroa me te ngaronga o te tohu nā te roa rawa
● Te ātete teitei me te wera mai i ngā tohu whaiti
● Te pokanoa whakawhitiwhiti kōrero i waenga i ngā rārangi tata
Kia mau ki ngā paerewa hoahoa pēnei i:
● PANUKU ● FEXT I roto i ngā atanga tere-tiketike (USB 3.0, HDMI), he mea nui te taurite pūmau o ngā takirua rerekētanga (±5mil) me ngā ara ara kua arotauhia hei pupuri i te pono o te tohu.

2, Ngā Taputapu Hoahoa Hanganga Whakarārangi

✕ Te Tatau Paparanga Tūpono me te Kōwhiringa Rauemi
Me whakaata te maha o ngā paparanga i te uaua o te ara iahiko me ngā hiahia wehewehe. Ka piki ake te utu me te uaua o te tukatuka i ngā paparanga nui rawa; ka whakawhāitihia te whakamahere tohu me te hiko i te iti rawa o ngā paparanga.

Kaua e whakararuraru i te whiriwhiri rauemi: whakamahia ngā rauemi auau teitei pēnei i Rogers RO4350B me:

● Pūmau iti o te hiko (Dk)
● Tauwehenga marara iti (Df)
Mā te whakamahi i te FR4 paerewa, i ngā papa rānei kāore i te tika mō ngā PCB mmWave (24–52GHz) ka hua ake ēnei:

● Te ngaronga nui o te tohu
● Te kore pumau o te ātete
● Te whakaiti i te mahi tuku raraunga

✕ Te Tirotiro i ngā Whakaritenga Rēhita me te Whakakikorua i waenga i ngā Papa

Mā te korenga o te tūnga o ngā paparanga > ±50μm ka puta he poto, he ara iahiko tuwhera, me te ngoikore o te mahi. Ka hua ake ēnei i te korenga o te whakapiripiri pai:

● Te tango i ngā mea i te kiri
● Whakaata tohu
● Te kore pumau o te miihini
Me mahi tahi ngā kaihoahoa me ngā kaihanga, me te kī:
● Te pāmahana whakarārangi: 180–220°C
● Pēhanga: 5–10MPa
● Te roanga: 30–60 meneti
● Taurite parahi me ngā puranga ōrite hei whakaiti i te ahotea

3, Ngā Taputapu Hoahoa Via me Pad

✕ He Momo me te Rahi Mā te Hē mō ngā Tohu Auau-Teitei

Mā te whiriwhiri i ngā poka-mā roto hei utu mō ngā vias matapo, huna rānei, ka piki ake te inductance/capacitance pirinoa, ka puta ai:

● Te whakaroa o te tohu
● Te whakapōturitanga
● Whakaata i roto i ngā hongere tere-rahi
Me karo hoki i ngā diameters iti rawa (● Te hē o te tūnga o te wiri
● He whakakikorua kino
● Te ātete teitei
Mā te kōwhiringa tika o te mā ka whakarei ake i te pono o te tohu me te āheinga hanga.

✕ Te Whakahāwea i te Hoahoa Papa me te Hototahi ki te Hononga

Me hoahoa ngā papa mō te tikanga whakapiri e hiahiatia ana:
● Me tika te rahi o ngā papa hei whakamakuku i te whakapiringa whakahurihuri
● Me whai wāhi te hononga ngaru hei ārai i te hononga
Ko ngā whakaotinga mata pēnei i te ENIG (Electroless Nickel Immersion Gold) ka whakarei ake i te kaha o te whakarewa me te ātete ki te waikura. Ko te hoahoa papa, te whakaotinga rānei ngoikore ka puta:
● Ngā hononga makariri
● Te hononga honohono
● Te waikura me ngā ara iahiko tuwhera

4, Ngā hapa, Ngā take pūtake, me ngā āputa kounga hoahoa

Ngā Tohumate o te Hapa Noa

● Te whakaiti i te tohu me te whakapōturitanga o te āhua ngaru

● Whakawhitiwhiti kōrero i waenga i ngā tohu

● Te wehewehenga o te paparanga me ngā ara iahiko poto

● Te whai i ngā whati, mā te aukati, mā te whakapūngao rānei o te papa

Ngā Take Pūtake

● Ngā rerekētanga o te ātete mai i ngā tātaitanga iti o te tohu

● Kāore i te rawaka te kōwhiringa rauemi mō ngā auau RF

● Te whakamahere whakarāpopototanga ngoikore me te kore he whakaritenga tukanga

● I whakaititia te aro mā te whakamahi i ngā pirinoa me ngā ātete keri

● Kāore ngā rahi o te papa i ōrite ki te tukanga whakapiri

Whakataurite i te Āputa Hoahoa

5、Ka taea e te Harikoa Katoa te Whakatau i ngā Wero Katoa
