Me whai pane pine paerewa me pane pine matotoru ngā papahiko hiko kaihoko — Whirihoranga 2.54mm me 1.27mm mō ngā whare huihuinga PCB

He aha i hiahia ai ngā taputapu hiko hou ki ngā mātotoru pane titi e rua

Ina tirohia ngā tahora o ngā papahoahoa o ngā hua hikohiko kaihoko o ēnei rā — mai i ngā pokapū kāinga atamai me ngā kuwaha IoT ki ngā taputapu petipeti me ngā taputapu hauora kawe — ka puta he tauira mārama. Kāore ngā kaihoahoa e whiriwhiri ana i waenga i ngā hononga kiato-paerewa me ngā hononga kiato-teitei; kei te whakamahi rātou i ngā mea e rua i runga i te PCB kotahi. Kua noho tēnei huarahi rua-piko hei hoahoa taunoa mō tētahi papaaho me whakataurite i te whai huatanga o te utu me ngā āhuatanga āhua e whakaiti ana.

He māmā noa iho te pūtake o tēnei ia. I te whānui haere o ngā āhuatanga me te whakaiti haere o ngā tapuwae papa, he utu kei ia mirimita tapawha o te whenua PCB. E whā ngā wā e pau ana i te pane titi 2.54mm te horahanga o te papa i te 1.27mm mō te maha o ngā titi. Heoi, kei te mau tonu te paerewa 2.54mm nā te mea he pakari ā-ringa, he ngāwari ake te mahi ā-ringa, he hototahi ki ngā taputapu whānui, me te pono o te tuku hiko me ngā atanga whakahaere tere-iti kua whakamātauhia mō te wā roa.

I taua wā anō, ko te horapa haere o ngā atanga raupapa tere-teitei pērā i te MIPI, LVDS, me te USB 3.x i runga i ngā papa kaihoko e hiahia ana kia paku ake te mokowā o ngā titi kia mau tonu ai te aukati whakahaere me te whakaiti i te roa o ngā poro. Ka whakautua tēnei hiahia e te pane titi 1.27mm pitch, e whakarato ana i tētahi hononga kiato e tautoko ana i ngā whakaritenga pono o te tohu me te noho hototahi tonu ki ngā tukanga huihuinga SMT paerewa. Kua kite mātou i te pikinga tonu o te ōwehenga o ngā hononga 1.27mm i roto i ngā pire rauemi e whiwhi ana mātou mai i ā mātou kiritaki whare huihuinga i roto i ngā tau e toru kua hipa, ā, e matapaetia ana ka haere tonu taua ia.

Nō reira, he mea nui te mārama ki te tautuhi, te hoko, me te huihui i ngā whānau hononga e rua mō tētahi whare huihuinga PCB e mahi ana ki te rāngai hiko kaihoko. I roto i tēnei aratohu, ka tirotirohia e mātou ngā āhuatanga hangarau o ia pitch, ka whakamāramahia ngā rautaki tahora me te hoko mahi, ā, ka tohaina ngā tawhā whakahaere kounga e whakamahia ana e mātou i roto i tā mātou ake hangahanga hei whakarite kia tutuki i ia pane titi ka tukuna e mātou ngā paerewa tono o ngā raina tiki-me-te-whakanoho aunoa.

Te Paerewa 2.54mm: Te Mahi a ngā Hononga PCB

Ko te pane titi 2.54mm (0.100-inihi) te hononga papa-ki-papa me te papa-ki-waea e whakamahia whānuitia ana i roto i te umanga hikohiko. I ahu mai tōna pūtake i ngā rā tōmua o te hanga PCB mā roto i te kōhao, ā, ahakoa te nekenga tekau tau ki te hangarau whakairi-mata, kāore i te ora noa te pitch 2.54mm engari i tupu haere tonu. E miriona ngā pane titi 2.54mm e hangaia ana e mātou i ia marama i roto i tō mātou whare i Ningbo, ā, kei te kaha tonu te tono puta noa i ngā kāwai hua katoa e mahi ana mātou.

He maha ngā āhuatanga e whakamārama ana i te mana pumau o tēnei piko. Tuatahi, ko te tawhiti 2.54mm e whakarato ana i te āputa nui i waenga i ngā pine tata, e hua ake ai he whānui ake ngā ātete hanga. Ka taea e ngā mīhini whakauru aunoa te whakanoho i ēnei hononga ki te tere tere me te iti rawa o ngā reiti hapa, ā, he māmā noa iho te whakanoho ā-ringa i te wā e hangaia ana, e mahi anō rānei. Tuarua, ko te whānuitanga o te pine mō ngā pane 2.54mm he 0.64mm te tapawhā, e hoatu ana ki ia pine he pakari ā-mīhini nui me te kaha kawe iahiko e pai ai te whakahaere i ngā reera hiko me te I/O whānui.

I roto i ngā tono papahoahoa hikohiko kaihoko, ka kitea tonutia e mātou ngā pane titi 2.54mm e whakamahia ana mō ngā atanga patuiro JTAG, ngā pane hōtaka SPI me I2C, ngā hononga pā, ngā tohu whakahaere o mua, me te tohatoha mana āwhina. Koinei ngā atanga he iti te tere tohu (i raro iho i te 50 MHz te nuinga), he mea nui te roa o te mahi miihini, ā, ko te kaha ki te hono ā-ringa me te momotu i ngā taputapu whakamātautau, i ngā taura rānei he whakaritenga hoahoa. He whānui hoki te tautoko i te pūnaha taiao: tata ki ngā kaiwhakarato hononga katoa, te whare huihuinga taura, me ngā taputapu hoahoa PCB e tuku ana i ngā wāhanga me ngā tapuwae hototahi-2.54mm.

Mai i te tirohanga a te whare huihuinga, he nui ngā painga o te piko 2.54mm ki te tukanga. He ngāwari ngā kōtaha whakarewa anō, he iti te mōrearea o te whakatō ki te urupā nā te nui o te titi, ā, he māmā noa te tirotiro tirohanga nā te mea he ngāwari te aromatawai i ngā poro whakarewa nā te piko whānui. Ina kōrero mātou ki a rātou mō ngā raraunga hua o ā mātou kiritaki, ko ngā papa he hononga 2.54mm te nuinga e whakaatu ana i ngā reiti hapa-mō-ia-miriona-whai wāhitanga iti iho i ērā he rerekē te matotoru. Nā tēnei rekoata pono te take e pupuri tonu ai te nuinga o ngā kaihoahoa i ngā atanga mana me te whakahaere ki te whatunga 2.54mm ahakoa ka nekehia e rātou ngā ara tohu ki ngā piko pai ake.

Te Kōwhiringa Matotoru-Teitei 1.27mm: Te Penapena Wāhi me te Pono o te Tohu

Ahakoa he pai te mahi a te whānuitanga 2.54mm mō ngā hononga whānui, ka noho hei raruraru ina he iti noa ngā whenua o te papa, ā, ka piki ake ngā auau tohu ki runga ake i te rau megahertz. Koinei te wāhi e uru ai te pane titi 1.27mm (0.050-inihi). Mā te haurua o te mokowā titi waenga-ki-waenga, ka taea e te whānuitanga 1.27mm ngā kaihoahoa te tākai i te kiato hononga tata ki te whā ngā wā ki roto i te taha papa kotahi, ki te wāhi tapuwae rānei.

Ka kitea tonutia te penapena wāhi ina whakatauritea ngā inenga o te tapuwae. Ko te pane titi 2x25 i te whānuitanga 2.54mm e 63.5mm te roa; ko te whirihoranga 50-titi kotahi i te whānuitanga 1.27mm e hiahia ana kia 31.75mm anake. Mō tētahi taputapu kaihoko kiato — he kaikorero atamai, he kaiwhakahaere mau, he HMI ahumahi iti rānei — ko taua rerekētanga pea te āputa i waenga i te whakauru i te hoahoa ki roto i tētahi wāhi whainga, te hiahia rānei ki te whakahou i te papa utu nui.

Haunga te penapena wāhi mata, ka tukuna e te pitch 1.27mm he painga nui mō te pono o te tohu. Ko te roa poto o ngā pine me te hononga piripono i waenga i ngā pine tata ka whakaiti i te inductance parasitic, ka whakapai ake i te kounga tohu auau-tiketike. Ina mahi tahi mātou me ngā kiritaki e hoahoa ana i ngā papa e kawe ana i ngā tohu whakaaturanga LVDS, ngā atanga kāmera MIPI, ngā ara raraunga USB 3.2 rānei, ka whiriwhiria e rātou ngā pane pine 1.27mm mō ēnei ara nui. Ka whakaitihia hoki e te roa iti o te pine te mōrearea o ngā whakaata i puta mai i te stub, he āwangawanga ka nui ake i runga ake i te 400 MHz.

He mea nui kia mōhio ki ngā taupatupatu. Ko te whānui 1.27mm e hiahia ana kia kaha ake ngā manawanui hanga - me whakahaere te ōritenga i roto i te 0.10mm, ā, ko ngā manawanui whakarite titi he tata ki te haurua o ngā mea e whakaaetia ana i te 2.54mm. Ka piki ake ngā whakaritenga tika o te whakatakotoranga aunoa, ā, me tirotiro pea te hihi-X, te AOI rānei hei manatoko i te kounga o te hononga honohono i raro i ngā tinana pai. Ka aro atu mātou ki ēnei wero mā te tā tika i ngā mate, te tirotiro tirohanga ā-roto i runga i tā mātou papa whakaputa, me te mahi tahi tata me ngā tīma hangarau tukanga a ō mātou kiritaki hei manatoko i te hototahitanga huihuinga i mua i te tīmatanga o te whakaputa papatipu.

Ngā Rautaki Tahora PCB Rua-Pitch mō ngā Whare Huihuinga

Ko te hoahoa i tētahi papahoahoa e whakauru ana i ngā pane titi 2.54mm me te 1.27mm me whakarite kia āta tupato kia kore ai e pāngia e ngā hapa noa. Kua tautokohia e mātou ngā rau o ngā hoahoa papa rua-waewae i roto i ngā tau, ā, he maha ngā mahi pai kua whakamātau tonu i tō rātou uara. Ko te kaupapa tuatahi ko te wehewehe ā-wāhi. Ka tūtohu mātou kia whakarōpūhia ngā hononga 2.54mm katoa ki tētahi rohe o te papa, me ngā hononga 1.27mm katoa ki tētahi rohe motuhake, ko te mea pai ko ngā taha papa rerekē. Mā tēnei wehewehenga ka māmā ake te whakarite taputapu i te wā o te huihuinga aunoa, ka whakaiti i te tūponotanga o te whakakapinga wāhanga tūpono, ā, ka pai ake te tirotiro kounga.

Ko te tuarua o ngā mātāpono ko te ōrite o te whakatakotoranga. Me rite te whakatakotoranga o ngā pane titi katoa o te papa kotahi ki te tuaka matua o te papa. Mā tēnei mahi ka whakaitihia te maha o ngā huringa whāngai me ngā hurihanga o te pūwero e hiahiatia ana e te mīhini tiki-me-te-whakanoho, ka whakapai ake i te wā huringa me te whakaiti i ngā hapa whakatakotoranga. E ai ki ō mātou wheako, ko ngā papa e whai ana i tēnei tikanga ka eke ki ngā reiti whakatakotoranga 8 ki te 12 ōrau te tere ake i ērā he whakatakotoranga whakauru.

Ko te whakahaere wera i te wā o te rerenga anō tētahi atu whakaaro nui. He rerekē ngā taumaha wera o ngā pane titi 2.54mm me te 1.27mm, arā, ka mimiti, ka horapa te wera i ngā tere rerekē i te wā o te tukanga whakapiringa rerenga anō. Mena ka whakanohoia ngā momo hononga e rua ki te papa kotahi, me whakarite te kōtaha rerenga anō kia uru ki te taumaha wera nui ake o te tinana 2.54mm me te kore e wera rawa ngā pine 1.27mm ngawari ake. Ka tūtohu mātou kia tohua he kaiwhakarato pane titi ka taea te whakarato aratohu taipitopito mō te kōtaha wera i runga i te taumaha titi tuturu me te whakakikorua o ngā wāhanga kua tonoa, he mea e tukuna ana e tā mātou tīma hangarau ki ngā hoa whare huihuinga.

Hei whakamutunga, whakaarohia ngā wāhanga tango-panel me te whakahaere. He ngawari ake te pakaru o ngā hononga 1.27mm angiangi mai i te piko o te papa i te wā tango-panel. Mena kei te taha o te taha o te papa, kei te taha rānei o ngā ripa pakaru ngā hononga 1.27mm, me tāpiri atu ngā taputapu tautoko, me whakarerekētanga hōhonutanga V-score rānei. Ka tohutohu mātou ki ō mātou kiritaki kia whakapuaki mai i tā rātou tahora panera ki a mātou i te tīmatanga o te tukanga hoahoa kia taea ai e mātou te tohu i ngā wāhi mōrearea pea, me te whakaaro hoki ki ngā whakarerekētanga tūnga hononga i mua i te whakaurunga o ngā taputapu.

Ngā Kōwhiringa Rauemi me te Whakakikorua: Te Tin, te Koura, me te Whakakikorua Whiriwhiri

He pānga tika te whiriwhiri i te rauemi whakakikorua mō ngā pane titi ki te utu, te kaha ki te whakarewa, te ātete pa, me te roa o te huringa hononga. Mō ngā tono papahoahoa hikohiko kaihoko, e toru ngā whirihoranga whakakikorua paerewa e tukuna ana e mātou, ā, mā te mārama ki te wā e tohua ai ia whirihoranga ka taea te penapena i te utu hoko nui me te kore e whakararu i te kounga hua.

Ko te whakakikorua tine te kōwhiringa tino ohanga, ā, ko te kōwhiringa taunoa mō ngā hua kaihoko e aro nui ana ki te utu. Ka whakamahia e ā mātou pane titi whakakikorua tine paerewa he mutunga tine-matte o te 3 ki te 5 maikiromita te matotoru i runga i te paparanga ārai nikara. He pai ake te tine matte i te tine kanapa mō te whakapiringa reflow nā te mea ka puta he hononga intermetallic pono ake, ā, ka ātete ki te hanganga tine-whiu. Mō ngā atanga e kite ana i te iti iho i te 50 huringa hononga puta noa i te roanga o te oranga o te hua - e kapi ana i te nuinga o ngā pane patuiro, ngā atanga hōtaka, me ngā hononga papa-ki-papa ā-roto - he tino rawaka te whakakikorua tine, ā, ko te uara pai rawa atu.

Ka tohua te whakakikorua koura ki runga i te nikara ina hiahiatia he pono ake, he roa ake rānei te manawanui ki te huringa hononga. Ka pania e mātou he paparanga koura o te 0.76 ki te 1.27 maikiromita (30 ki te 50 maikiro-inihi) ki runga i te ārai nikara o te 1.27 ki te 2.54 maikiromita. Ka mau tonu te ātete hononga pumau o ngā hononga whakakikorua koura i roto i te 500 neke atu rānei o ngā huringa hononga, ā, ka ātete ki te waikura me te waikura i roto i ngā taiao makuku. Nā tēnei ka waiho te whakakikorua koura hei whiringa paerewa mō ngā hononga anga-waho, ngā atanga whakamātautau-me-te-ine, me tetahi tono ka noho kore hononga te hononga mō ngā wā roa i mua i te whakamahinga.

Ko te whakakikorua whiriwhiri te tohu o te huarahi waenga e arotau ana i te utu. I roto i tēnei tukanga, ka whiwhi te wāhi pa o te titi i te mutunga koura, ko te hiku honohono ka mau tonu te mutunga tine. Ka aro tēnei huarahi ki te haumi whakakikorua ki te wāhi e tino hira ana - i te atanga honohono - me te pupuri i ngā utu honohono iti. Ka kite mātou i te whakakikorua whiriwhiri kua tohua haeretia i roto i ngā hikohiko kaihoko taumata waenga, kei te piki haere ngā tumanakohanga pono o te hua engari kei te kaha tonu te pēhanga utu o te pire-o-ngā rauemi. Ka tutuki ā mātou tukanga whakakikorua katoa ki ngā whakaritenga ā-ahu me te mahi kua tohua i roto i te IEC 60603-2, me te whakarite kia taea ai te mahi tahi me ngā pūnaha hononga paerewa puta noa i te ao.

Mana Kounga: Te Hononga-tahi, te Kaha Pupuri Pine, me te Āheinga Whakapiripiri

Ehara i te mea whiriwhiri te whakahaere kounga i roto i te hanga pane pine — koinei te turanga e whakawhirinakihia ana te reiti hua o te whare huihuinga me te pono o te hua whakamutunga. Kei a mātou he kawa tirotiro maha-wāhanga e kapi ana i ngā tawhā nui katoa mai i te tiwhikete rauemi mata tae noa ki te tākai whakamutunga. Mō ngā whare huihuinga PCB e arotake ana i ngā kaiwhakarato pane pine, ko ngā inenga kounga tino nui e toru hei aromatawai ko te ōritetanga, te kaha pupuri pine, me te kaha honohono.

Ko te ōritetanga e pā ana ki te nui o te takoto o ngā titi katoa i roto i te hononga i te papa kotahi. Mō te whakatakotoranga SMT aunoa, me whakahaere te ōritetanga i roto i te 0.10mm mō ngā pane piko 2.54mm me te 0.08mm mō ngā pane piko 1.27mm. Mena ka nui ake te ōritetanga i ēnei manawanui, kāore pea ētahi titi e pā tika ki te whakapiri whakarewa i te wā e whakatakotoranga ana, ka hua ake he hononga whakarewa tuwhera, makariri rānei i muri i te rerenga anō. Ka ine mātou i te ōritetanga i runga i ia puranga whakaputa ma te whakamahi i ngā whakataurite papatahi whatu, ā, ka whakaratohia he pepa raraunga me ia tuku.

Ko te kaha pupuri pine — te kaha e hiahiatia ana hei tango i te pine mai i te whare ārai — he mehua mō te pakari ā-mīhini. Mō ngā pine 2.54mm, ka tohua e mātou he kaha pupuri iti rawa o te 0.5 kgf; mō ngā pine 1.27mm, ko te iti rawa ko te 0.3 kgf, e whakaatu ana i te wāhi iti o te taunga pokanoa. Ko ngā pine e rahua ana i te whakamātautau kaha pupuri ka tūpono ka tangohia i te wā e whakahaere ana i te papa, i te whakamātautau aunoa, i te ratonga rānei i te mara. Ka whakamatautauria ia puranga ka tukuna e mātou hei whakaū i te tutuki i ēnei iti rawa.

Ka aromatawaihia te āheinga honohono i runga i IPC-A-610 ngā paearu whakaae. Ka whakahaerehia e mātou ngā whakamātautau taurite-mākū me ngā aromatawai tuku-me-titiro ki ngā pine tauira mai i ia oma whakaputa hei manatoko kei te whakarato te whakakikorua i te hipoki honohono pumau, kore-āputa. Mō ngā pine whakakikorua-tine, ka whakahaerehia hoki e mātou ngā whakamātautau koroheketanga tere i te pāmahana me te haumākū teitei hei whakaū i te kaha honohono mō te wā roa. Ko tā mātou whānuitanga katoa o ngā hua pane titi e hangaia ana kia rite ki ēnei paerewa, ā, e mihi ana mātou ki ngā arotake a te hunga tuatoru o ā mātou tukanga kounga i ngā wā katoa.

Ngā Whakaaro Hokonga Papatipu mō ngā Whare Huihuinga PCB

Ko te hoko nui i ngā pane titi mō te hanga hikohiko kaihoko ehara i te mea ko te whakatairite noa i ngā utu waeine. Ka mahi tahi mātou me ngā tīma hoko o te whare huihuinga ki te arotau i te utu katoa o te whenua, ā, he maha ngā āhuatanga e wehewehe ana i te mekameka tuku pane titi e whakahaeretia pai ana mai i te mekameka tauhohe.

Ko te whakaaro tuatahi ko te whakakotahi. Mā te tiki i ngā pane titi 2.54mm me te 1.27mm mai i te kaihanga kotahi — he rerekē ki te wehewehe i te rahinga puta noa i ngā kaiwhakarato maha — ka puta he painga tūturu: he tuhinga kounga kotahi, he pūwāhi whakapā kotahi mō ngā huringa hangarau, he tuku kaipuke whakakotahi e whakaiti ana i ngā utu utanga, me te kaha ake o te whiriwhiringa ki te utu rahinga. Ka tukuna e mātou he hanganga utu taumata e utu ana i ngā ota whakakotahi puta noa i ngā whānau pitch me ngā whirihoranga hononga.

Ko te whakahaere wā-arataki te tuarua o ngā mea nui. Ka tukuna ngā whirihoranga paerewa 2.54mm mai i tō mātou whare putunga o Ningbo i roto i ngā rā pakihi e 3 ki te 5. Ko te tatau pine ritenga, te whakakikorua motuhake, ngā momo 1.27mm rānei e hiahiatia ana he 15 ki te 25 ngā rā pakihi i runga i te rahinga. Ka pupuri mātou i ngā whakaaetanga haumaru-taonga me ā mātou kiritaki auau, me te pupuri i ngā taonga ārai ka taea te whakakore i roto i te wā poto hei utu i ngā pikinga whakaputa me te kore e utu i te taonga nui i te whare huihuinga.

Kaua e warewarehia ngā tuhinga me ngā whakaritenga. Kei roto i ia utaina nui ka tukuna atu e mātou ngā tiwhikete hanganga, ngā pūrongo tirotiro i ngā āhuatanga, ngā hua whakamātautau matotoru whakakikorua, me ngā whakapuakitanga RoHS/REACH. Mō ngā whare huihuinga e mahi ana ki ngā mākete kua whakaritea pērā i ngā taputapu hauora, ngā hua kaihoko e tata ana ki ngā motuka rānei, ka taea e mātou te whakarato i ngā whakapuakitanga rauemi i roto i te whakatakotoranga IPC-1752 me te tautoko i ngā arotake wheketere i raro i ngā kaupapa tohu motuhake a te kiritaki. Mā te whakatū i tēnei turanga tuhinga i te tīmatanga o te whanaungatanga kaiwhakarato ka whakakore i ngā whakaroa i te wā tirotiro e haere mai ana, ā, ka tere ake te wā ki te whakaputa mō ngā hoahoa papa hou.
