Te Hoahoa mō te Hanganga i roto i ngā PCB Auau-Teitei: Te Whakahāngai i te Auahatanga ki te Motu Whakaputa

Kupu Whakataki

I roto i te hoahoa o ngā PCB auau-teitei, hoahoa mō te hangahanga (DFM) ko te piriti matua e hono ana i te auahatanga hangarau ki te whakaputanga hua nui, utu-whai hua. Mō ngā kaihanga hoahoa PCB RF, ko te mōhio ki ngā mātāpono DFM ko te hanga papa e kore e mahi noa engari he pono hoki, he tauine, he whai hua hoki ki te ōhanga.

Mai i te mokowā tohu ki hanganga whakarārangi, mā te hoahoa, me āhuahanga papa, me whai whakaaro ia taipitopito ki ngā āhuatanga tūturu o ngā rauemi auau-tiketike me ngā ātete hanga. E whakamārama ana tēnei tuhinga i ngā āhuatanga matua o te hoahoa PCB auau-tiketike ka taea te hanga me tōna pānga ki te kounga, te whai huatanga, me te utu.

1. Hototahi ki te Hoahoa Aroturuki me te Hanganga

Whānui me te Mokowā Tino Pai o te Ara

I roto i ngā PCB auau-teitei, ka pā te whānui me te mokowā o ngā tohu ki ngā mea e rua mahi hiko (hei tauira, te whakahaere ārai mate) me te hua hanga.

• Āraitanga whāinga: 50Ω, 75Ω rānei—e hiahiatia ana te whānui/ngā mokowā tika e tatauhia ana mā te whakamahi i te raina Dk
• Ngā herenga hangaMō ngā rauemi auau-teitei, he tairongo ake te rerekētanga o te tukanga i te paerewa FR-4

Aratohu HoahoaKaua e pana i te rohe o raro o te ātete ki te whakairo. Engari ko te 3mil/3mil, whakamahia 4 miriona/4 miriona he nui ake rānei i runga i ngā papa whakarakei auau-tiketike hei ārai i ngā poto, ngā tuwhera, ngā kino iti rānei.

Te Ara Tohu Whai Hua

Ko te huarahi whai hua mō ngā tohu tere-rahi me penei:

• Tika, poto hoki (te whakaiti i te whakaiti tohu)
• Wehea e te rohe auau (te aukati i te whakawhitiwhiti kōrero)
• He pai mō te whakamātautau (me ngā papa whakamātautau e wātea ana)

Ka whakapai ake tēnei te pono o te tohu, tautoko whakamātautau whakaputa, ā, ka ārai i ngā hapa mahi i te wā e whakatinanahia ana.

2. Hanganga Whakarārangi: Te Whakataurite i ngā Hiahia Hiko me te Hanga

Te Tatau o ngā Paparanga me te Kōwhiringa Rauemi

• He paparanga anō = he pai ake te wehenga tohu/mana, engari he nui ake te utu me te mōrearea
• He iti rawa ngā paparanga = te whakahaere EMI ngoikore, te ara ara kua pakaru

Mō ngā tono RF uaua pēnei i te 5G, 10+ ngā paparanga he mea noa. Rogers RO4350B he kōwhiringa rongonui mō ngā hiahia iti mō te Dk/Df, engari me kaha ake te whakahaere i te tukatuka.

Tohutohu HangarauKōwhiria ngā papa rākau, ehara i te mea mō te mahi anake, engari mō ō rātou āhuatanga anō hoki te āheinga miihini, whanonga hononga, me pumau wera i te wā o te whakarārangi.

Ngā Whakaaro mō te Tukanga Whakarārangi

Me whakahaere pai ngā PCB RF maha-paparanga ki:

• Te tika o te rēhitatanga (±50μm)
• Ngā tawhā pēhi: 180–220°C, 5–10MPa, 30–60 meneti i runga i te taurite o te prepreg me te parahi

Arotautanga puranga me taurite tohatoha hiko-kore me te ōritetanga o te parahi hei whakarite kia ōrite te whakarara, kia kore ai hoki e piko, e wehewehe rānei.

3. Hoahoa Via me te Papa: Te Whakahāngai ki te Kaha Tukanga

Momo Mā te Wiri me te Rahi Wiri

• Ngā poka-mā roto he māmā ake te hanga engari ka whakauruhia mai ngā pirinoa
• Ngā via matapo me ngā via tanumia whakaitihia te whakapōturitanga o te tohu engari whakapiki i te utu me te uauatanga

Taunakitanga HoahoaWhakamahia ngā momo via e tika ana mō te whānui o tō tohu me te whakapūtanga manawanui. Āta karohia ngā diameters via iti iho i te 0.2 mm, nā te mea ka uaua te keri me te whakakikorua.

Te Hoahoa Papa mō te Pono o te Hononga

• Me whakarite kia ōrite ngā papa tapuwae wāhanga me kōtaha rerenga anō
• Mō te rere anō: arotauhia te rahi o te papa kia ōrite te rere o te tūhono
• Mō te tūhono ngaru: whakahohea te waikeri whakarewa me te āhua/tahora papa tika

Te karo i ngā raruraru whakapiriWhakaarohia te ENIG, te OSP whiriwhiri rānei mō ngā tono auau-teitei. Āta karohia ngā papa kua waikurahia, kua kore rānei e pai te whakakikorua, ka pā kino pea tēnei te kōhatutanga o ngā urupā, te hono, rānei ngā hononga makariri.

4. Ngā Hapa Noa me ngā Otinga Hangarau

Ngā Hapa Raina

• Ngā tohu: He whānui iti, he poto, he whānui koretake rānei
• Ngā TakeNgā rārangi angiangi rawa, te whakahaere koretake o te whakairo, te keri hē te tūnga
• Ngā otinga:
• Whakamahia ngā tikanga tiaki ngā āhuahanga e pai ana ki te whakairo
• Aroturuki i te matū o te etchant me te whakarite i te mata PCB
• Whakatikatikahia ngā mīhini keri me te tirotiro i te pakaru o ngā mata

Ngā Take Hononga Papa

• Ngā tohu: Te tango i te kiri, ngā tarau poto paparanga o roto
• Ngā TakeTe pēhanga/pāmahana whakapuru ngoikore, te he rānei o te tūnga
• Ngā otinga:
• Tīpakohia ngā prepreg ātete-makuku
• Whakamahia ngā pūnaha whakahāngai whakarara tino tika
• Hoahoa me te rawaka ngā āputa i waenga i ngā paparanga

Ngā hapa o te Via me te Pad

• Ngā tohuNgā via kua āraia, te whakakikorua ngoikore, te hiki papa, te waikura rānei
• Ngā TakeNgā para o te keri, te matū whakakikorua ngoikore, te punga papa koretake
• Ngā otinga:
• Whakapai ake i te horoi i muri i te keri
• Kia mau tonu te matū me ngā tawhā o te kaukau whakakikorua
• Arotauhia te āhua o te papa, ā, whakamahia takai ārai-waikura

Te Whakakī i te Āputa: Ka Tuku Uara te Hoahoa Hangaia

Ngā kamupene e whakauru ana Ngā mātāpono DFM ki roto i te hoahoa PCB RF e pai ake ana i ō rātou hoa whakataetae:

• Te hua tuatahi teitei ake
• He iti ake ngā mahi anō, ngā mahi hoahoa rānei
• He pai ake te pono mō te wā roa
• Te whakaiti i ngā amuamu a te kiritaki me ngā utu pūtāhui

He rerekē, ko te kore e aro ki te hanga ka arahi ki ngā whakaroa whakaputa pinepine, ngā hua iti, me te kounga hua kore pumau—ina koa i roto i rererangi, hauora, rānei ngā hikohiko tiaki, ina ehara te rahunga i te kōwhiringa.
