Te Pānga o ngā Ātete Pitch Hononga PCB ki te Pono o te Tohu i roto i ngā Taupānga Auau-Teitei
TL;DR — Ngā Whakaaro Matua
- Ka whakatau tika te ātete o te pitch hononga i te pono o te tohu i ngā auau teitei. Ka taea e te peka +/-0.05mm te neke i te aukati āhuatanga mā te 5-12 ohms, ka puta he whakaata tohu ine me ngā hapa raraunga.
- Mō ngā tono i runga ake i te 1 GHz, tohua te ātete pitch o te +/-0.05mm, neke atu rānei. Ko ngā hononga ātete paerewa +/-0.1mm e herea ana ki te mahi i raro iho i te 500 MHz.
- He mea tino nui te whiriwhiri rauemi: Ka whakawhānui ake ngā dielectrics LCP i ngā rohe auau ka taea te whakamahi mā te 30-50% ki tua atu i ngā hononga PA66/PA6T paerewa i te teitei kotahi.
- E toru ngā momo oro o te raupapa NBJGE IC Socket (1.27mm, 2.0mm, 2.54mm) me ngā āheinga tika mō te whakawhitiwhiti kōrero, te whakahaere ahumahi, me ngā tono RF.
Ko te ātete ki te piko o te hononga PCB tētahi o ngā tawhā tino warewarehia engari he mea nui e whakatau ana i te pono o te tohu i roto i ngā pūnaha hiko auau-tiketike. Ina tata ngā wā pikinga tohu ki te 1 nanohekona, ki raro iho rānei, ka tīmata ngā āhuatanga ā-tinana o te atanga hononga ki te whakahaere i te whanonga hiko. Ko ngā kaihoahoa e whiriwhiri ana i ngā hononga mō ngā whakawhitiwhiti kōrero Kāore e taea e ngā hanganga, ngā pūnaha whakahaere ahumahi, ngā kōwae RF rānei te whakamahi i te manawanui pitch hei whakatakotoranga tuarua.
Nā te mea ahakoa he iti noa te rerekētanga o te tawhiti i waenganui i te pa ka puta he momotu ātete e whakaata ana i te pūngao ki te pūtake, kaua ki te tuku tika ki te kawenga. I roto i tētahi pūnaha 50 ohm e whakahaerehia ana i te 2.4 GHz, ka taea e te taahiraa aukati i puta mai i te manawanui pitch o te 10 ohms anake te whakaputa i te ōwehenga ngaru tū ngaohiko (VSWR) neke atu i te 1.5:1, ka arahi ki te ngaronga mana 4% ka honoa puta noa i ngā atanga hononga maha.
Te Mārama ki te Pitch Connector PCB me tōna Tūranga i roto i te Tuku Tohu
Te pikinga hononga — te te tawhiti pokapū-ki-pokapū i waenga i ngā hoapā tata i roto i te hononga PCB, i te putanga IC rānei — e tautuhi ana i te āhua taketake o te ara tuku. Mā tēnei inenga, me ngā āhuatanga rauemi dielectric me te āhua whakapā, ka whakatūria te aukati āhuatanga (Z0) e pā ana ki te tohu i a ia e haere ana i roto i te hononga.
I roto i te hoahoa PCB auau-tiketike, ko te whāinga kia mau tonu te aukati rite puta noa i te ara tohu katoa mai i te taraiwa ki te kaiwhiwhi. Mā te panoni ohorere o te aukati ka puta he whakaata ā-wāhanga. Ka tangohia e te pūngao whakaata mai i te tohu e haere whakamua ana, ka whakaitihia te kaha o te tohu i te kaiwhiwhi, ā, ka puta pea he hapa moka i roto i ngā pūnaha matihiko.
Ko te whanaungatanga i waenga i te teitei o te hononga me te aukati e whai ana i te ariā raina tuku kua whakapumautia. Ko te teitei whānui ka puta he aukati teitei ake mō tētahi āhua whakapā kua hoatu, ko te teitei whaiti ia ka whakaiti i te aukati mā te whakanui ake i te hononga capacitive i waenga i ngā kaiwhakahaere tata.
He aha te Manawanui ki te Pitch te Tawhā Matua — Ehara i te Pitch anake
Ko ngā uara papa ingoa (2.54mm, 2.0mm, 1.27mm) e whakarato ana i te āhua whāinga, engari ko ngā ātete hangahanga e whakatau ana i te pumau o taua āhua puta noa i ngā rahinga whakaputa. Ko te hononga kua tohua ki te pitch 2.54mm engari i hangaia me te ātete +/-0.15mm ka whakaatu i te rerekētanga nui o te aukati mai i te pine ki te pine, mai i te puranga ki te puranga.
Nā te mea he rite whakamuri te aukati ki te mokowā i waenga i ngā ara iahiko tohu me ngā ara iahiko whakahoki, ka taea e te rerekētanga +/-0.1mm o te pitch te whakaputa i te rerekētanga aukati o +/-4 ki te +/-8 ohms i roto i te whirihoranga miroiti 50 ohm noa. Ina tae tēnei rerekētanga ki te +/-12 ohms, neke atu rānei — he mea noa ki ngā hononga utu iti — ka nui rawa te motumotu o te aukati ka heke te kounga o te tohu ahakoa i ngā auautanga taurite.
| Ātete (+/-mm) | Rerekētanga Ārai (+/-ohms) | Auautanga Whakamahinga Mōrahi (GHz) | Te Whakamahinga Noa |
|---|---|---|---|
| +/-0.15 | 8-12 | 0.3 | Ngā hononga hiko, I/O tere-iti |
| +/-0.10 | 5-8 | 0.8 | Tohu whānui, mana whakahaere ahumahi |
| +/-0.05 | 3-5 | 3.0 | Gigabit Ethernet, kāri raina waea |
| +/-0.03 | 1-3 | 10.0 | Ngā kōwae RF, hanganga 5G |
Koia te take e wehewehe ai ngā hoahoa auau-tiketike nui mai i ngā huarahi taumata-pārekareka mā te tautuhi i te ātete ki te oro. Ko te akomanga manawanui +/-0.05mm e wātea ana i roto i ngā kōtui IC tino tika NBJGE e tohu ana i te paepae mahi mō te mahi pono i runga ake i te 1 GHz.
Whakataurite i te Pitch o te Socket IC: 1.27mm vs 2.0mm vs 2.54mm
E toru ngā momo oro paerewa o te raina hua hononga IC a NBJGE, ia momo oro kua arotauhia mō ngā rohe tono auau-tiketike rerekē. I runga i ngā inenga TDR o te wheketere i mahia i te Hauwhā Tuatahi o te tau 2026 puta noa i te 200+ tauira, e whakaatu ana te whakataurite e whai ake nei i ngā tawhā pono o te tohu i inehia mō ia akomanga oro.
| Tawhā | Teitei o te 1.27mm | Teitei o te 2.0mm | Teitei o te 2.54mm |
|---|---|---|---|
| Manawanui Paerewa | +/-0.05mm | +/-0.05mm | +/-0.10mm (tūturu) / +/-0.05mm (tino pai) |
| Ārai Āhuatanga | 42+/-5 ohms | 48+/-4 ohms | 52+/-5 ohms |
| Ngaronga Whakauru (i te 3 GHz) | -0.8 dB | -0.6 dB | -0.5 dB |
| Whakawhitiwhiti kōrero (i te 2 GHz, ngā pine e tata ana) | -22 dB | -28 dB | -32 dB |
| Whānuitanga Whaihua (-3 dB) | 2.5 GHz | 4.0 GHz | 5.5 GHz |
| Te Matotoru o te Pine (pine mō ia cm2) | 62 | 25 | 15 |
| Taupānga Pai rawa atu | Pahi matihiko kiato-teitei | Ngā pūnaha tohu whakauru | RF / auau-teitei anarau |
E whakaatu ana ā mātou inenga i tētahi taurite mārama: he nui ake te kiato o ngā titi i te iti o te reo irirangi, engari he nui ake te whakawhitiwhiti kōrero me te iti iho o te aukati, ā, ka whakaitihia te mahi auau teitei e ēnei e rua. Ko te momo pitch 2.54mm, me tōna crosstalk iti ake (-32 dB vs -22 dB mō te 1.27mm) me te tata atu ki te aukati pūnaha 50 ohm, he pai ake i ngā hononga pitch pai ake i roto i ngā tono RF anarau i runga ake i te 1 GHz.
He tirohanga nui tēnei mā ngā kaihanga hoahoa: ina he mea nui te pono o te tohu, kaua e whakamahi noa i te iti rawa o te oro hei penapena wāhi. Ko te pūoko IC oro 2.54mm te mea pai mō te nuinga o ngā atanga RF me ngā whakawhitiwhiti kōrero tae atu ki te 5 GHz.
Me pēhea te hanga a ngā manawanui hanga i ngā momotu ātete
E toru ngā āhuatanga hanga motuhake e huri ana i te manawanui o te pitch ki te whakahekenga tohu e taea te ine: te hapa tūnga whakapā, te rerekētanga o ngā āhuatanga o te ārai, me te kore ōrite o te matotoru whakakikorua.
Tikanga Take #1: Nā te hapa tūnga whakapā i te wā o te tukanga whakairo me te whakauru ka hanga he mokowā kore taurite i waenga i ngā hoapā tohu tata, ka huri te kaha mō ia wae roa mai i te pine ki te pine. Ka puta he rerekētanga ā-rohe o tēnei rerekētanga kaha ā-rohe i te rerekētanga ātete e rite ana i ia pūwāhi atanga. I te 2.4 GHz, ka puta he huringa kaha tata ki te 0.08mm i waenga i ngā pine tata e rua, e rite ana ki te taahiraa ātete o te 7 ohms.
Tikanga Take #2: Nā te mea ka heke te rauemi whare ārai (ko te PA66, PA6T, LCP rānei te tikanga) i te 0.2-1.5% i te wā e whakamataohia ana te whakarewa werohanga, he rerekē te tawhiti whakapā tuturu i muri i te whakamatao i te hoahoa o te kōhao pokepokea ai. Ko te hononga piko 2.54mm i whakarewahia ki roto i te PA6T me te hekenga pokepokea ai he 0.6% ka heke te piko toharite o te 0.015mm. Ina honoa ki te kakahu taputapu, te rerekētanga pāmahana, me te rerekētanga puranga rauemi, ka taea e te manawanui whakaemi te eke ki te 0.10-0.15mm.
Tikanga Take #3: Nā te mea he whiriwhiri whakakikorua koura (te nuinga o te 0.76(((-1.27 um i runga i te arai nikara) ka tāpirihia he 15-25 um o te rauemi mō ia mata pa, ko ngā rerekētanga o te matotoru whakakikorua puta noa i te rīpene hononga ka hanga he huringa iti engari ka taea te ine. Ko ngā raina whakakikorua whiriwhiri tere-teitei me te aroturuki matotoru XRF wā-tūturu ka pupuri i tēnei rerekētanga ki te +/-3 um, engari ko ngā tukanga paerewa ka whakaae pea ki te +/-8 um.
Te Tūranga o te Rauemi Hikohiko i roto i te Mahi Auau-Teitei
He pānga nui tō te rauemi ārai e karapoti ana i ngā hononga hononga PCB ki te pumau o te tohu — he nui atu i te ātete ki te oro i ētahi wā. Ko te pūmau dielectric (Dk) me te tauwehenga marara (Df) o te rauemi whare e whakatau ana i te whanonga o te mara hikohiko i te atanga hononga.
| Rauemi | Dk i te 1 GHz | Df i te 1 GHz | Te Pāmahana Mōrahi (C) | Utu Whakapā |
|---|---|---|---|---|
| PA66 (naira paerewa) | 3.5-4.0 | 0.020-0.030 | 120 | 1.0x |
| PA6T (nailoni pāmahana teitei) | 3.3-3.8 | 0.010-0.018 | 180 | 1.4x |
| PPS (polyphenylene sulfide) | 3.0-3.5 | 0.004-0.008 | 220 | 1.8x |
| LCP (pūhui karaihe wai) | 2.8-3.3 | 0.002-0.005 | 260 | 2.5x |
Ngā hikohiko LCP whakawhanui ake i te awhe auau e taea ana te whakamahi i tētahi hoahoa pitch kua hoatu mā te 30-50% ki te whakaritea ki ngā whare PA66 paerewa, nā te mea he iti ake, he pumau ake hoki te pūmau dielectric o te LCP me te iti rawa o te tauwehe marara. Mō te putanga IC pitch 2.54mm e whakahaere ana i te 3.5 GHz, ka whakaitihia e te whare LCP te ngaronga whakaurunga mai i te -0.9 dB ki te -0.5 dB — he whakapainga 44%.
Kei te tuku a NBJGE i ngā kōwhiringa LCP me PPS dielectric puta noa i tana whānuitanga hua hononga IC mō ngā kiritaki e hiahia ana ā rātou tono ki te pono o te tohu mōrahi i ngā auau neke atu i te 2 GHz.
Te Whakahekenga o te Pono o te Tohu: Mai i te Ariā ki te Pānga Ka Taea te Ine
E toru ngā huarahi ka taea te ine i te hekenga o te tohu i puta mai i te manawanui o te papa: te nui haere o te ngaronga hokinga mai, te nui haere o te whakawhitiwhiti kōrero, me te kohikohinga wiri i roto i ngā awa raraunga mamati.
Ko te ngaronga whakahoki — inehia hei S11 i roto i te dB — e ine ana i te nui o te tohu taupatupatu ka whakaatahia anō nā te kore ōrite o te aukati. Mō te hononga e mahi ana i te 3 GHz me te manawanui +/-0.10mm, ko te mate whakahokinga noa he -12 ki te -15 dB, ko te tikanga he 3-6% o te mana tohu ka whakaatahia. Mā te whakapai ake i te manawanui ki te +/-0.05mm ka pai ake te mate whakahokinga ki te -18 ki te -22 dB, ka whakaitihia te mana whakaata ki te 0.6-1.5%.
Mā te whakawhitiwhiti kōrero — e inehia ana ko S21 (pito tata) ko S31 rānei (pito tawhiti) — ka ine i te hononga kāore e hiahiatia i waenga i ngā ara tohu tata. I te 2 GHz, he tata ki te 10 dB te nui ake o te whakawhitiwhiti oro a te hononga pitch 1.27mm i te hononga pitch 2.54mm i roto i te whirihoranga ōrite.
Ko te kohikohi wiri — te rerekētanga wā o ngā whakawhiti tohu mamati — koinei pea te pānga tino nui ki te mahi, nā te mea ka whakaiti tika i te tawhē wā i roto i ngā kaiwhiwhi mamati. Ko te kore ōrite o te aukati i puta mai i te hononga o te 10 ohms i te tere raraunga 1.25 Gbps ka puta he 25-40 ps o te wiri whakatau. Ina toru, e whā rānei ngā atanga hononga kei roto i te ara tohu, ka taea e te wiri kua kohia te kai i te 30-50% o te tahua wā wae e wātea ana.
Ngā Aratohu Kōwhiringa Whaihua mō ngā Kaihoahoa Hoahoa
Kōwhiria te teitei me te akomanga o te hononga PCB me tō akomanga manawanui i runga i te auau whakahaere i te tuatahi, kātahi ko te kiato o te pine me te utu.
Mō ngā tono DC ki te 500 MHz
He rawaka te teitei paerewa 2.54mm me te ātete +/-0.10mm. He rawaka te mahi a ngā dielectric PA66, PA6T rānei. Ko ngā tono noa ko ngā tohu whakahaere hiko, ngā atanga pūoko ahumahi, me te kohikohi raraunga tere-iti.
Mō ngā tono 500 MHz ki te 3 GHz
Tīpakohia te teitei 2.54mm, 2.0mm rānei me te ātete +/-0.05mm me te PA6T, PPS rānei hei ārai i te oro. Tauwhāitihia te aukati whakahaere (50 ohms +/-5 ohms) ka tono raraunga whakamātautau TDR wheketere. Ka kapi tēnei awhe i te Gigabit Ethernet, ngā kōwae pito-mua WiFi 5/6, me te hanganga 4G LTE.
Mō ngā tono 3 GHz ki te 10 GHz
Whakamahia te whānuitanga 2.54mm me te ātete +/-0.03mm me te LCP dielectric. Tonoa te whakaahuatanga katoa o te tawhā-S tae atu ki te 10 GHz. Ka hipokina e tēnei ngā kaiwhiwhi amiorangi 5G NR i raro i te 6 GHz me te Ku-band. Ka tutuki i te NBJGE te manawanui +/-0.03mm mā te whakamahi i ngā taputapu pokepokea tika me te pumau pāmahana taputapu 48-hāora i te wā e whakahaerehia ana te whakaputanga.
Mō runga ake i te 10 GHz
Whakaarohia ngā otinga hononga ritenga me ngā papa whenua kua whakauruhia. Kāore i te tūtohutia kia whakamahia ngā tūhono IC paerewa i runga ake i te 10 GHz me te kore he whakatauira SI whānui. Pātai atu ki tā mātou tīma hangarau mō ngā taunakitanga motuhake mō te tono.
Ngā Tikanga Whakamātautau me te Manatoko
Ko te TDR (whakaata rohe-wā) te tikanga whakamātautau matua mō te manatoko i te kōtaha ārai hononga i raro i ngā āhuatanga whakahaere tūturu. Ka tukuna e te taputapu TDR he pātere hiko tere-ara (ko te tikanga he 35 ps te roa o te pikinga, e rite ana ki te whānui o te 10 GHz) ka ine i ngā whakaata. Ka puta ia aukati ātete hei pīka i runga i te ngaru TDR.
Mā te ine i ngā tawhā-S a te VNA (kaitātari whatunga vector) ka whakaratohia te āhuatanga rohe-auau e hiahiatia ana mō te whakatauira hoahoa. Mō ia IEC 60512-27-100, me mahi ngā inenga tawhā-S mō ngā hononga PCB i te iti rawa 5x te auau mahi mōrahi.
Ko te tātari hoahoa kanohi te tikanga tino māmā ki te titiro mō te aromatawai i te kounga tohu mamati mā te hononga. Mō te hononga IC NBJGE 2.54mm te whānui me te ātete +/-0.05mm, e whakaatu ana ngā whakamātautau wheketere i te 2.5 Gbps i te whakatuwheratanga kanohi poutū o te 320 mV (68% o te kaha taraiwa) me te wiri whakapae o te 22 ps mai i te tihi ki te tihi.
Whakataurite Whakataetae: NBJGE me ngā Paerewa Ahumahi
Nā te mea kāore e rite te mahi manawanui o ngā pūoko IC "tika" katoa, i whakaritea tika e mātou ētahi wāhanga kaiwhakarato e toru i te tawhiti 2.54mm mā te whakamahi i ngā raraunga whakamātautau wheketere mai i ngā tauira 50-wahi.
| Tawhā | Te Tika o te NBJGE | Paerewa Ahumahi | Taumata Tahua |
|---|---|---|---|
| Manawanui Ine (6 sigma) | +/-0.05mm | +/-0.10mm | +/-0.15mm |
| Āraitanga TDR (whainga 50 ohm) | 52+/-4 ohms | 49+/-8 ohms | 50+/-12 ōhm |

| Ngaronga Whakahoki i te 3 GHz | -20 dB | -14 dB | -9 dB |
| Matotoru Iti o te Whakakikorua Koura | 0.76 kotahi | 0.50 kotahi | 0.25 kotahi |
| Tāurangi Utu | 1.0x | 0.7x | 0.4x |
Whakamutunga me ngā Hipanga e Whai Ake Nei
Ko te ātete ki te piko o te hononga PCB he tawhā hoahoa tuatahi mō te pono o te tohu auau-tiketike, ehara i te whakatakotoranga hanga tuarua. Ko te rerekētanga i waenga i te manawanui +/-0.10mm me te +/-0.05mm ka rerekē pea i waenga i te hoahoa kanohi e pahemo ana me te kore e angitu i te 3 GHz, e tika ana mō te pono o te mara mō ngā taputapu whakawhitiwhiti kōrero me ngā taputapu whakahaere ahumahi.

Ngā Pātai Auau
Ka taea e au te whakamahi i tētahi hononga pitch 1.27mm mō ngā tono 5G?
Ae, engari me āta whakaaro ki te hoahoa. Ka taea te whakamahi i tētahi hononga pitch 1.27mm mō te 5G NR i raro i te 6 GHz mēnā kei roto i te hoahoa he parenga whenua-papa, ā, kei raro iho i te 3 GHz te auau. I runga ake i te 3 GHz, ko te whakawhitiwhiti kōrero teitei ake (-22 dB) me te aukati iti iho (42 ohms) ka pāngia pea e te hekenga tohu e kore e whakaaetia.
Kia pēhea te auau o taku manatoko i te ātete ki te piko o te hononga i roto i te hanga?
Me uru ki ngā arotakenga kounga a ngā kaiwhakarato te ine i te tono i ia ono marama. Mō ia ISO 9001 ngā whakaritenga, tonoa ngā raraunga ine AOI mai i ngā marama 12 kua hipa o te whakaputanga me ngā uara Cpk neke atu i te 1.33.
Ka pāngia te manawanui o te paparanga e ngā panonitanga pāmahana?
Ae, ka pā te whānui wera ki te teitei o te hononga i te wā e mahi ana. Ka whakawhanui te hononga LCP 2.54mm te whānui (CTE o te 5-10 ppm/C) mā te 0.0013mm pea mō ia pikinga 10°C. Ka taea e te whakawhanuitanga tāpiri puta noa i te hononga 64-pine te eke ki te 0.08mm i te rerekētanga pāmahana 50°C. Mō ngā tono whānuitanga pāmahana, tohua ngā rauemi e ōrite ana ki te CTE.
