Ruku Hōhonu ki te Hoahoa PCB RF: Mai i ngā Kaupapa Taketake ki ngā Auahatanga Hou
Hei rōpū ngaio e whai pūtake hohonu ana ki te hoahoa PCB, Harikoa Nuikua whakapau kaha ki te whakarato i ngā hangarau me ngā otinga taumata-teitei mō te umanga. I roto i tēnei tuhinga, ka whakaratohia e mātou he tātaritanga whānui o Hoahoa PCB RF, e whakapuaki ana i ō mātou wheako whānui me ngā māramatanga ki ngā tikanga matatau mō ngā kaihangarau PCB.
1. Te Mārama ki ngā Āhuatanga o te Ara Iahiko RF me ngā Whāinga Hoahoa
(1) Ngā Āhuatanga o te Ara Iahiko RF
Ka mahi ngā ara iahiko RF i roto i ngā taiao auau teitei, ā, ka nui ake te uaua o ngā āhuatanga tuku tohu i ngā ara iahiko tuku iho. Ngā taputapu whakatauira paerewa pērā i REKAhe uaua ki te tātari tika i ngā ara iahiko RF nā ngā āhuatanga pēnei i ngā roangaru poto ake, ngā pānga raina tuku, ngā whakaata, ngā hurihanga, me te hononga.
Matatau Pūmanawa EDA, pērā i ADS (Pūnaha Hoahoa Matatau) me te HFSS (Whakatauira Hanganga Auau-Teitei), whakamahi i ngā rauropi matatini pēnei i te taurite ā-hāngai me ngā tikanga whakaatahei whakatauira i ngā ara iahiko RF me te tino tika. I mua i te whakamahi i ēnei taputapu, he mea nui kia mārama ki ngā āhuatanga matua o te ara iahiko RF.
Hei tauira:
●Pānga kiri:I ngā auau teitei, ka rere te iahiko i runga i te mata o te kaiarahi, ka whakanui ake i te ātete me te pā ki te kounga tuku tohu.
●Te aukati o te raina tuku:Ka awehia tēnei e te auau tohu, te roa o te tohu, me te rauemi hiko-kore, e pā tika ana ki te whakaata tohu me te whai huatanga o te tuku.
(2) Ngā Whāinga Hoahoa PCB RF
1. Ngā Whāinga Hoahoa Tuku
Me taurite te hoahoa o te tuku te whai huatanga o te mana me te pono o te tohu:
●Te whakaiti i te whakapaunga hikome te whakarite kia rawaka te mana tuku, he mea nui hoki mō ngā taputapu ringaringa me ngā whakawhitiwhitinga amiorangi.
●Me tuku te tuku kaua e pokanoame ngā hongere tata. Me whakahaere tika ngā whakakaha hiko mō te mana putanga me te rārangitangahei ārai i te whakapohehetanga o te tohu me te pokanoa o te hongere tata.
2. Ngā Whāinga Hoahoa a te Kaiwhiwhi
Me tutuki i te hoahoa o te kaiwhiwhi ngā whāinga matua e toru:
●Te aro nui:Me whakahoki tika te kaiwhiwhi i ngā tohu whakauru ngoikore, he iti noa iho i te nuinga o te wā 1µVHe mea nui te whakahaere haruru, me te hiahia ngā whakakaha haruru iti (LNA) me ngā tahora ara iahiko kua arotauhia.
●Te whakakorenga whai hua o te pokanoa:Ka whakamahia ngā tātari me te arotautanga ara iahiko hei whakakore i ngā tohu i waho o te roopu i roto i ngā taiao aukume matatini.
●He iti te whakamahinga hiko:He mea nui tēnei kia tutuki ai ngā whakaritenga whānui mō te whai huatanga o te pūngao i roto i ngā pūnaha RF.
2. Ngā Huānga Matua o te Hoahoa PCB RF
(1) Kōwhiringa Rauemi
Te whiriwhiri i te tika rauemi papahe mea nui mō Ara iahiko RFmahi. Ko ngā tawhā matua ko:
1. Pūmau Ārai Hiko (Dk):
●Ngā pānga te aukati me te tere horapa tohu.
●He mea nui te pumau—ka taea e ngā rerekētanga iti o te Dk te arahi ki ngā taupatupatu ārai, ka hua ake te whakaata me te whakaiti i te tohu.
●Tauira: Rogers RO4350Be tuku ana i te mahi auau teitei pumau, he mea tino pai mō Ngā teihana turanga 5G me ngā whakawhitiwhitinga amiorangi.
2. Tauwehe Whakamarara (Df):
●Whakatau te ngaronga o te pūngaoi te wā e tukuna ana te tohu.
●Ngā rauemi iti-Df(hei tauira, Ngā papahanga e hangai ana ki te PTFE) whakaiti i te ngaronga tohu, whakapai ake i te whai huatanga o ngā tono ngaruiti.
3. Tauwehenga o te Whakawhanuitanga Wera (CTE):
●Ngā Pānga te pumau o ngā āhuatangaputa noa i ngā pāmahana rerekē.
●Ka taea e ngā uara CTE kāore i te ōrite te hua ngā pakaru o te hononga honohono me ngā pakaru o te ara iahikoi roto i ngā tono pērā i ngā hikohiko ā-rangi me ngā waka.
(2) Te Whakahaere Ārai Ārai
Ko te taurite impedance tētahi wāhanga matua o te hoahoa PCB RF. Kei roto i ngā impedance raina tuku paerewa 50Ω me te 75Ω, me ngā manawanui tino pakari o ±5% tae atu ki te ±3%.
Ko te whakahaere tika i te aukati me tatau tupato i:
●Whānui me te mokowā o te arai
●Te matotoru o te hiko-ā-ira
●Te matotoru o te pepa parahi
E ai ki IPC-2251, ko ngā hanganga tuku RF matua ko ngā rārangi miroiti, te rārangi miroiti, me ngā arataki ngaru papatahiHei tauira, ko te tātai aukati raina miroitiko:
Z0=87εr+1.41ln(5.98h0.8w+t)Z_0 = \frac{87}{\sqrt{\varepsilon_r + 1.41}} \ln\left(\frac{5.98h}{0.8w + t}\right)Z0=εr+1.4187ln(0.8w+t5.98h)
Kei hea ME₀ko te ārai āhuatanga, εrko te pūmau whakapūmau hiko, hko te matotoru o te papa, I rotoko te whānui o te tohu, ā, tko te matotoru o te parahi.
(3) Hoahoa Hototahi Aukume Hiko (EMC)
1. Te Whakahaere i te Whakararuraru Hikohiko (EMI)
Ko ngā pūtake EMI noa i roto i te PCB RF ko:
●Ngā wāhanga hohe
●Ngā tohu tere-teitei
●Ngā pūnaha hiko
Ngā rautaki whai hua mō te whakaiti i te EMI:
●Whakaarotautanga Tahora Porowhita:Wehea ngā ara iahiko mana-teitei me te mana-itihei whakaiti i te pokanoa.
●Ngā Tikanga Whakatakoto Whenua:Whakamahia te whenua maha-ira, kotahi-ira, ranu rāneiki te whakarato ngā ara whakahoki iti-ārai.
●Ngā Tikanga Whakamarumaru:Whakatinana ngā ārai whakarewahei aukati i ngā tukunga hikohiko.
2. Hoahoa o te Ngāwari ki te Hikohiko (EMS)
Mā te whakarei ake i te EMS ka ārai ngā ara iahiko i ngā pokanoa o waho:
●Whakaitihia te horahanga porowhita tohuhei whakaiti i te haruru e puta mai ana.
●Whakanohoia ngā wāhanga tātari kia rautaki(ngā pūnga iahiko, ngā ine hiko) hei pehi i ngā tohu kāore e hiahiatia.
●Whakamahia ngā pūnga wetewetei ngā pine hiko hei whakau i te tuku hiko me te tātari i te haruru auau teitei.
3. Te Tukanga Hoahoa PCB RF me ngā Mahi Pai rawa atu
(1) Hoahoa Tauira
He hanganga pai hoahoaKo te turanga tēnei o te hoahoa PCB RF.
●Te kōwhiringa wāhanga:Kōwhiria ngā wāhanga i runga i te te pikinga, te tatauranga haruru, me te auau tapahi.
●Te whakahaere i ngā tawhā pirinoa:Whakaarohia me pēhea te kaha pirinoa me te ine hikopā ki te mahi auau teitei.
●He tahora mārama, he whakatakotoranga arorau:Whakaritea ngā wāhanga mō te rere o te tohu me te rapu hapa whai hua.
(2) Hoahoa Tahora PCB
1. Ngā Mātāpono Whakatakotoranga Whānui
●Whakarite ngā kōwae mahi e tata ana tetahi ki tetahihei whakaiti i te ngaronga o te tohu.
