Ngā Whakamārama mō ngā Paerewa Kounga PCB Auau-Teitei | Ngā Tirohanga Hanga PCB RF
Kupu Whakataki
I roto i te umanga hikohiko e tere whanake ana i ēnei rā, he mea nui ngā PCB auau-teitei i roto i ngā tono pēnei i te whakawhitiwhiti kōrero 5G, te whakatere amiorangi, ngā pūnaha radar, me ngā hikohiko kaihoko kounga teitei. Ko te mahi a ēnei pūnaha e whakawhirinaki nui ana ki te kounga o te PCB, ā, he mea nui te piri ki ngā paerewa kounga pakari. I te mea ka piki ake ngā tumanakohanga mō te mahi a ngā taputapu hiko, ka piki ake hoki ngā paerewa mō ngā PCB RF me te auau-teitei. Mō ngā kaihanga hoahoa PCB, ko te mārama me te whakatutuki i ēnei paearu te mea nui ki te whakawhanake i ngā hua hiko pono me te mahi-teitei.
Ngā Paerewa Kounga Matua mō ngā PCB Auau-Teitei
1. Ngā Paerewa Mahi Hiko
Mana Ārai Āhuatanga
Ko ngā ara iahiko auau-tiketike e hiahia ana kia tino tika te whakahaere i te aukati āhuatanga, i roto i te ±5% o te whāinga hoahoa. Hei tauira, he maha ngā wā ka hiahiatia he aukati 50Ω, 75Ω rānei mō ngā PCB teihana turanga 5G. Ka taea e ngā peka ke te arahi ki ngā whakaata tohu, te whakaheke i te pono o te tohu, te whakaiti i te tere tuku raraunga, me te whakanui ake i ngā reiti hapa moka. Hei pupuri i te tika o te aukati, me āta tautuhi ngā kaihoahoa i te whānui o te tohu, te mokowā tohu, te matotoru o te dielectric, me te whiriwhiri i ngā rauemi me ngā pūmau dielectric pumau (Dk).
Ngaronga Tuku Tohu
Kāore e taea te karo i te ngaronga o te tohu i roto i te tuku auau-teitei, ā, kei roto ko ngā ngaronga o te kaiārahi me te mate hiko-kore. I ngā auau ngaru-mirimita (hei tauira, 24GHz–52GHz), me whakaiti te ngaronga o te tohu—i te nuinga o te wā ka puritia i roto i te 0.5dB ki te 1dB ia inihi. Mā te whakamahi i ngā rauemi iti te horapa (Df) pēnei i te Rogers RO4350B（, me ngā puranga PCB kua arotauhia me te tahora tohu, ka taea te whakaiti i te whakaiti tohu.
Te Whakakore i te Whakawhitiwhiti Kōrero
Ka taea e te pokanoa ara tata, te whakawhitiwhiti kōrero rānei, te whakararu i te pono o te tohu auau-teitei. Ka whakamahia ngā inenga pēnei i te NEXT (Near-End Crosstalk) me te FEXT (Far-End Crosstalk) hei aromatawai i te pokanoa. Ko ngā paerewa ahumahi e hiahia ana kia raro iho i te -30dB te NEXT me te FEXT i raro iho i te -40dB. Ko te pehi whai hua ko te whakanui ake i te mokowā ara, te whakatinana i ngā papa whenua, te ārai rānei, me te arotau i te āhua o te ara.
2. Ngā Paerewa Hanganga ā-Tino
Te Tika o te Ahu
Mō te whakaurunga pūnaha maeneene, me whai taurite ngā āputa o ngā PCB auau-teitei. Me whakahaere te matotoru o te papa i roto i te ±0.05mm, me te diameter o ngā kōhao i roto i te ±0.02mm. He mea nui te miihini tika me te whakahaere tukanga pakari kia tutuki ai ēnei paerewa—ki te kore e tutuki, ka raru pea te huihuinga me te heke o te mahi.
Papatahi o te Papa
Ka pā tika te papatahi ki te kounga o te whakapiri me te pumau o te tohu. Ko ngā paerewa ahumahi e whakawhāiti ana i te piko o te papa ki raro iho i te 0.5%. Mā ngā tukanga whakapiringa whakahaere (te pāmahana, te pēhanga, te tere whakamatao) me ngā puranga paparanga kua hoahoatia tika ka āwhina ki te pupuri i te papatahi. Ka taea e te papatahi ngoikore te arahi ki ngā hapa whakapiri me ngā rerekētanga ātete āhuatanga nā te āhua rerekē o te ahua.
3. Ngā Paerewa Pono
Ātete Taiao
Me tu atu ngā PCB auau-teitei ki te pāmahana, te haumākū, me ngā taiao waikura. Hei tauira, i raro i ngā āhuatanga 85°C/85% RH mō ngā hāora 1000, me noho pūmau te mahi hiko me te hanganga. Mā ngā mahi tiaki pēnei i te kopare tūhono kounga teitei, ngā whakaotinga mata ENIG, me ngā paninga makuku/ārai ka āwhina i te whakapakari i te roa o te taiao.
Te Pono o te Hononga Whakakotahi
Ko ngā hononga whakarewa te hononga matua i waenga i ngā wāhanga me te PCB. Me tu atu ēnei i te ahotea miihini me te huringa wera (hei tauira, -40°C ki te 125°C, 1000 huringa) me te kore e pakaru, e motu rānei. Ko te whakarite kia taea te whakarewa, kia tika ngā kōtaha pāmahana, me te kounga o te mata te mea nui ki ngā hononga pakari.
Te Tātaritanga o te Hapa: Ngā Take, Ngā Tohu, me Ngā Āputa Mahi
1. Ngā Raru Mahi Hiko
Ngā Tohu: Te tuku tohu kore pumau, te whakaiti nui o te tohu, te whakaata nui, te whakawhitiwhiti kōrero rerekē rānei. Tērā pea ka kitea e ngā taputapu whakamātautau ngā āhua ngaru kua hē, te whakaiti i te kaha o te oro, te pikinga rānei o te haruru.
Ngā Take: Te hoahoa ārai kore tika, te roa rawa o te tohu, te mātotoru rānei, ngā rauemi kāore i te tika (hei tauira, te Dk kāore i te pumau, te Df teitei rānei), te whakahaere whakairo ngoikore, te matotoru koretake rānei o te dielectric.
Āputa Mahi: Ka tautokohia e ngā papa e tutuki ana i ngā paerewa te tuku raraunga tere-tiketike pumau. Tērā pea ka pakaru ngā whakawhitiwhiti kōrero me ngā raruraru kapinga mēnā he papa hapa, inā koa i ngā teihana turanga 5G.
2. Ngā Hapa Hanganga ā-Tinana
Ngā Tohu: Te hē o te tūnga i te wā e huihui ana, te piko o te papa, te rahi o ngā kōhao kua hē te whakanoho, kāore rānei i te ōrite. Ka taea e ngā taputapu tirohanga, taputapu ine rānei (hei tauira, ngā calipers, te ine whatu 2D) te tautuhi i ēnei hapa.
Ngā Take: Kāore i te tika te tiaki o ngā taputapu, kāore i te tika te pēhanga whakapiringa, kāore i te ōrite te rahi o te pehanga, te tere o te whakamatao, te ngoikore rānei o ngā mata wiri.
Āputa Mahi: Mā ngā PCB pakari te hanganga ka whakarite kia piri te whakaurunga me te hononga hiko pono, engari mā ngā papa hapa ka nui ake te mōrearea o te ahotea miihini, ngā pakaru hononga, me ngā whati ara tohu.
3. Ngā Take Pono
Ngā Tohu: Ngā pakaru o te hononga whakarewa, te waikura, te wehewehe, te pakaru rānei o te whakamarumaru. Ka kitea ēnei hapa i roto i te tirotiro karuārai me ngā whakamātautau ātete whakamarumaru.
Ngā Take: Te piri kino o te mata, te koretake o te whakapiringa, te pānga rānei ki ngā taiao pāmahana teitei, haumākū teitei, matū rānei i te wā e rongoa ana, e whakamahia ana rānei.
Āputa Mahi: Ka mahi pūmau ngā PCB pono-teitei i roto i ngā taiao uaua, he mea nui mō ngā hiko rererangi me ngā hiko hauora. Ka piki ake te wā kore mahi, ngā utu tiaki, ā, ka tūpono pea he mōrearea whakahaere nui nā te iti o te pono.
