Mai i te Hoahoa ki te Mahi: Me pēhea te Ārai i ngā Mōrearea Kounga i roto i te Hanga PCB Auau-Tiketike
I roto i te hanga PCB auau teitei, ko te wāhanga hoahoa hei tūāpapa mō te kounga—pērā i te turanga e whakatau ana i te kaha o tētahi whare teitei. Ka taea e ngā kōwhiringa hoahoa ngoikore te arahi ki te whakapōturitanga o te tohu, te pokanoa hikohiko, me ngā arai hangahanga. Mō Ngā kaihoahoa hoahoa PCB RF, he mea nui te matatau ki te whakahaere kounga i te wāhanga hoahoa hei whakarite i te mahi i roto i ngā tono pēnei i Ngā teihana turanga 5G, ngā pūnaha amiorangi, me whakawhitiwhitinga ngaru-mirimita.
Kia tūhuratia te pānga o ngā whakataunga hoahoa o te wāhanga tuatahi ki te whakahaere aukati, te ara tohu, te kōwhiringa rauemi, me te pono o te hanganga—me te hura i ngā pūtake o ngā take kounga.
Te Hoahoa Paparanga Tohu: Te Taurite Ārai me te Āhuatanga Ara
1. Hoahoa Āraitanga Tika1.
I roto i ngā ara iahiko auau teitei, ārai āhuatanga me tino ōrite ki ngā whāinga hoahoa (i te nuinga o te wā 50Ω, 75Ω rānei, me te manawanui o ±5%) hei karo whakaata tohu me te whakahekenga. He rite ngā rerekētanga o te aukati ki ngā ngaru oro e pupuhi ana i ngā pakitara mārō—ka whakapohehetia te tohu e ngā whakaata, ā, ka piki ake te ngā reiti hapa moka ā, kua heke iho te rere o ngā raraunga.
Ko te whakatutuki i te ōritetanga ārai e hiahiatia ana:
- Ngā tataunga whānui me ngā mokowā tika mō te tohu
- Tika matotoru o te hiko-kore whakahaere
- Tūmau pūmau whakapūmau hiko (Dk) ngā rauemi (hei tauira, ngā papa whakarewa a Rogers)
Hei tauira, ko te Rogers RO4350B, me te Dk pumau me te iti o te tauwehenga tohatoha (Df), e whakamahia whānuitia ana i roto i ngā PCB 5G me mmWave hei whakarite tuku tohu iti-ngaronga.
2. Te Āhuatanga Ara Arotau
He rite te whakatakotoranga ara ki te whakamahere tāone mō ngā waka tohu. Ko te whakatakotoranga kino—he roa rawa, he whaiti, he kikī rānei ngā ara—ka puta he tohu ngaronga, whakaroa, rānei whakapōturitanga. Ka whakanui ake hoki te ara kikī i te mōrearea o whakawhitiwhiti kōrero, inā koa i waenganui i ngā tohu tere-tiketike e tata ana.
Ngā paearu ahumahi ：
- NEXT (Whakawhitiwhiti Tata-Mutu)
- FEXT (Whakawhitiwhitinga-Mutunga-Tawhiti)
Hei whakaiti i te pokanoa:
- Whakanuia te mokowā i waenga i ngā tohu
- Tāpiri ngā paparanga parepare whenua
- Whakamahia ngā āhuahanga whetū, mekameka daisy rānei i runga i te rere o te tohu
Mā ēnei rautaki whakatakotoranga ka whakaitihia te EMI, ka tiakina te pono o te tohu, ā, ka whakapai ake i te pono o te ara iahiko auau-tiketike.
Te Kōwhiringa Rauemi me te Arotautanga Whakatakotoranga
1. Te Taurite i te Papatūāpapa mō te Mahi Auau-Teitei1.
Te whiriwhiri i te tika rauemi raima he mea nui ki te whakahaere i te whakaiti tohu. Mō ngā tono mmWave (hei tauira, 24GHz–52GHz), ko ngā rauemi me iti te Df kia iti rawa te ngaronga o te tuku.
Tauira:
Ka tutuki i a Rogers RO4350B te mate tuku iti rawa 0.5–1 dB ia inihi, e tutuki ana i ngā paerewa whakawhitiwhiti kōrero mmWave tino pakari.
He rite tonu te hiranga Te pumau o Dk—ka pāngia te aukati e ngā piki me ngā heke, ā, ka whakaiti i te mahi a te tohu. Me whiriwhiri e ngā kaihoahoa ngā rauemi me Dk matapaetia ngā uara i raro i ngā āhuatanga rerekē o te pāmahana me te haumākū.
2. Hangarau Whakatakoto-ake
Ka pā te whakarārangi paparanga ki te pono o te tohu me hototahitanga hikohiko (EMC)Ka taea e ngā puranga kua hoahoatia pai te:
- Whakaitihia whakaroa tohu
- Whakaitihia whakawhitiwhiti kōrero
- Whakapai ake te whakamarumaru me te EMC
Ngā mahi pai rawa atu:
- Tūnga te mana me ngā paparanga whenua e tata ana mō te parenga tino pai
- Tūnga ngā paparanga tohu hei whakaiti i ngā ara tuku
- Pupuri te mokowā paparanga ōrite mō te pumau o te aukati
Ka taea e te hoahoa whakarārangi kino—hei tauira, ko te tawhiti nui i waenga i te tohu me te whenua—te arahi ki te whakaroa kua piki ake, haruru irahiko, me Ngā take EMI.
Ngā Hapa Noa: Ngā Take, Ngā Tohu, me te Āputa Mahi
1. Ngā Take Mahi Hiko
Ngā tohu:
- Te whakaiti i te tohu
- Te whakapōturitanga o te āhua ngaru i runga i ngā oscilloscopes
- Ka ngaro ngā raraunga, ka rahua rānei te pūrere mā te whakawhitiwhiti kōrero.
Ngā Take Pūtake:
- Te whakahaere ārai hapa
- Te ara kore e tino pai
- Kōwhiringa rauemi kāore i te tika
- Te matotoru koretake o te whakairo, te matotoru dielectric rānei
Āputa Mahi:
E whakaatuhia ana e ngā PCB kua hoahoatia pai ngā ngaru ma, ōrite me te whakawhiti raraunga tere-teitei. Ka pā pea ngā mea kāore i te pai te hoahoa ngā whakarēreatanga whakawhitiwhiti kōrero, pokanoa whatunga, rānei te whakahekenga tohu, inā koa i roto i ngā tono tairongo pērā i ngā teihana turanga 5G.
2. Ngā Hapa Hanganga
Ngā tohu:
- Ngā rahinga papa kāore e taea te whakamanawanui
- Te piko, te piko rānei
- Te kore e tika te tūnga, te kore rānei e ōrite te rahi o ngā kōhao
Ngā Take Pūtake:
- Hoahoa matotoru paparanga kore hototahi
- Te korenga e whai whakaaro mō te manawanui ā-mīhini o ngā taputapu hanga
- Te kore aro te whakawhānui wera me kākahu wiri
Āputa Mahi:
Ka hono pai ngā papa pono ki ngā wāhanga me ngā whare. Ka piki ake ngā papa hapa. ngā hapa huihuinga, ngā ara iahiko tuwhera, rānei ngā tohu pakaru, ka nui te utu mō te mahi anō, ā, ka iti ake te pono o te pūnaha.
