He aha te via i roto i te PCB?
Ko ngā Vias ngā kōhao e tino kitea ana i roto i te hanga PCB. Ka honoa e rātou ngā paparanga rerekē o te whatunga kotahi engari kāore i te whakamahia mō ngā wāhanga honohono. Ka taea te wehewehe i ngā Vias ki ngā momo e toru: ngā kōhao whakawhiti, ngā vias matapo, me ngā vias tanumia. Ko ngā taipitopito mō ēnei vias e toru kei raro nei:
Te Tūranga o ngā Vias Matapo i roto i te Hoahoa me te Hanga PCB
Ngā via matapo
He kōhao iti ngā via matapo e hono ana i tētahi paparanga o te PCB ki tētahi atu, me te kore e haere mā roto i te papa katoa. Mā tēnei ka taea e ngā kaihoahoa te hanga PCB uaua, kapi tonu hoki, he pai ake, he pono ake hoki i ngā tikanga tuku iho. Mā te whakamahi i ngā via matapo, ka taea e ngā kaihoahoa te hanga i ngā taumata maha ki runga i te papa kotahi, ka whakaiti i ngā utu wāhanga, ka tere ake hoki ngā wā whakaputa. Heoi, ko te hohonu o te via matapo kaua e neke ake i tētahi ōwehenga motuhake e pā ana ki tōna kōhao. Nō reira, he mea nui te whakahaere tika i te hohonu o te keri (tuaka-Z). Ka taea e te whakahaere koretake te arahi ki ngā uauatanga i te wā o te tukanga whakakikorua hiko.
Ko tētahi atu tikanga mō te hanga i ngā arai matapo ko te keri i ngā kōhao e tika ana i roto i ia paparanga ara iahiko takitahi i mua i te whakapiripiri i a rātou. Hei tauira, ki te hiahia koe i tētahi arai matapo mai i te L1 ki te L4, ka taea e koe te keri i ngā kōhao i te L1 me te L2, ā, i te L3 me te L4, kātahi ka whakapiripiri i ngā paparanga e whā. Me whakamahi tēnei tikanga i ngā taputapu tūnga me te whakarite tino tika. E whakaatu ana ngā tikanga e rua i te hiranga o te tika i roto i te tukanga hanga hei whakarite i te mahi me te pono o te PCB.
Ngā vias tanumia
He aha ngā via tanumia?
He aha te rerekētanga i waenga i te micro via me te buried via?
He mea nui ngā via huna i roto i te hoahoa PCB, e hono ana i ngā ara iahiko paparanga o roto, me te kore e toro atu ki ngā paparanga o waho, ka kore e kitea mai i waho. He mea nui ēnei via mō ngā hononga tohu o roto. He maha ngā kōrero a ngā tohunga o te umanga PCB, "Ka whakaitihia e ngā via huna te tūponotanga o te pokanoa tohu, ka pupuri i te haere tonu o te aukati āhuatanga o te raina tuku, ā, ka penapena wāhi waea." Nā tēnei ka pai mō ngā PCB kiato teitei me te tere teitei.
Nā te mea kāore e taea te keri i ngā vias tanumia i muri i te whakakikoruatanga, me mahi te keri i runga i ngā paparanga ara iahiko takitahi i mua i te whakakikoruatanga. He roa ake te wā e pau ana i tēnei tukanga ki te whakataurite ki ngā poka-roto me ngā vias matapo, ā, ka nui ake ngā utu. Ahakoa tēnei, ko ngā vias tanumia te nuinga e whakamahia ana i roto i ngā PCB kiato-nui hei whakanui ake i te wāhi e taea ai te whakamahi mō ētahi atu paparanga ara iahiko, ā, ka whakarei ake i te mahi whānui me te pono o te PCB.
Mā roto i ngā kōhao
Ka whakamahia ngā kōhao whakawhiti hei hono i ngā paparanga katoa mā te paparanga o runga me te paparanga o raro. Ka taea te whakamahi i te whakakikorua parahi i roto i ngā kōhao hei hononga ā-roto, hei kōhao tūnga wāhanga rānei. Ko te kaupapa o ngā kōhao whakawhiti he tuku i te hiko e haere ana, i ētahi atu wāhanga rānei mā roto i tētahi mata. Ka whakaratohia e ngā kōhao whakawhiti he huarahi hei whakairi me te whakau i ngā hononga hiko ki runga i ngā papa hiko tā, ngā waea, ngā papa rite rānei e hiahia ana ki tētahi pūwāhi tāpiri. Ka whakamahia hoki ēnei hei punga me ngā here i roto i ngā hua ahumahi pēnei i ngā taonga whare, ngā whata, me ngā taputapu hauora. Hei tāpiri, ka taea e ngā kōhao whakawhiti te whakarato i te urunga whakawhiti mō ngā tokotoko miro i roto i ngā mīhini, i ngā wāhanga hanganga rānei. Hei tāpiri, me whai i te tukanga mono i ngā kōhao whakawhiti. Ka whakarāpopototia e Viasion ngā whakaritenga e whai ake nei mō te mono i ngā kōhao whakawhiti.
*Horoia ngā kōhao mā roto mā te whakamahi i te tikanga horoi plasma.
*Me whakarite kia kore he paru, he paru, he puehu rānei i roto i te kōhao.
*Inehia ngā kōhao mā roto kia tino hototahi ki te taputapu mono
*Kōwhiria he rauemi whakakī e tika ana mō te whakakī i ngā kōhao: te pani silicone, te putty epoxy, te pahuka whakawhanui, te kāpia polyurethane rānei.
*Tāuruhia te taputapu mono ki roto i te kōhao puta.
*Puritia kia mau ki tōna tūranga mō te iti rawa 10 meneti i mua i te tuku i te pēhanga.
*Mukua te tāpiri i ngā mea whakakī katoa i te taha o ngā kōhao ina oti.
*Me tirotiro i ngā pū kōhao i ia wā, i ia wā, kia mōhio ai kāore he turuturu, he pakaru rānei.
*Whakahoutia te tukanga e tika ana mō ngā kōhao rerekē te rahi.
Ko te whakamahinga matua o te hononga hiko ko te hononga hiko. He iti ake te rahi i ērā atu kōhao e whakamahia ana mō ngā wāhanga honohono. Ka nui ake ngā kōhao e whakamahia ana mō ngā wāhanga honohono. I roto i te hangarau hanga PCB, he tukanga taketake te keri, ā, kāore e taea te mangere. Kāore e taea e te papa hiko te whakarato hononga hiko me ngā mahi taputapu pumau me te kore e keri i ngā kōhao e hiahiatia ana i roto i te pereti parahi. Mena ka puta he raruraru i roto i te tukanga keri i tētahi mahi keri hē, ka pā ki te whakamahinga o te hua, ka pakaru rānei te papa katoa, nō reira he mea nui te tukanga keri.
Ngā tikanga keri o ngā vias
E rua ngā tikanga keri mō te vias: te keri ā-ringa me te keri taiaho.
He tukanga nui te keri ā-ringa mā roto i ngā kōhao i roto i te umanga PCB. Ko ngā kōhao mā roto, arā, ko ngā kōhao mā roto, he pūwhera porotaka e tika ana mā roto i te papa, ā, e hono ana i tētahi taha ki tētahi taha. Ka whakamahia ēnei hei whakairi i ngā wāhanga me te hono i ngā ara iahiko hiko i waenga i ngā paparanga. Ko te keri ā-ringa o ngā kōhao mā roto ko te whakamahi i ngā taputapu motuhake pērā i ngā keri, ngā riipene, me ngā kokopi hei hanga i ēnei pūwhera me te tika me te tika. Ka taea te mahi ā-ringa, mā roto rānei i ngā mīhini aunoa i runga i te uaua o te hoahoa me ngā whakaritenga whakaputa. Ka pā tika te kounga o te keri ā-ringa ki te mahi me te pono o te hua, nō reira me mahi tika tēnei taahiraa i ia wā. Mā te pupuri i ngā paerewa teitei mā te keri ā-ringa, ka taea te hanga pūwhera pono me te tika kia pai ai te hononga hiko.
Te keri laser
He tukanga nui te keri ā-ringa mā roto i ngā kōhao i roto i te umanga PCB. Ko ngā kōhao mā roto, arā, ko ngā kōhao mā roto, he pūwhera porotaka e tika ana mā roto i te papa, ā, e hono ana i tētahi taha ki tētahi taha. Ka whakamahia ēnei hei whakairi i ngā wāhanga me te hono i ngā ara iahiko hiko i waenga i ngā paparanga. Ko te keri ā-ringa o ngā kōhao mā roto ko te whakamahi i ngā taputapu motuhake pērā i ngā keri, ngā riipene, me ngā kokopi hei hanga i ēnei pūwhera me te tika me te tika. Ka taea te mahi ā-ringa, mā roto rānei i ngā mīhini aunoa i runga i te uaua o te hoahoa me ngā whakaritenga whakaputa. Ka pā tika te kounga o te keri ā-ringa ki te mahi me te pono o te hua, nō reira me mahi tika tēnei taahiraa i ia wā. Mā te pupuri i ngā paerewa teitei mā te keri ā-ringa, ka taea te hanga pūwhera pono me te tika kia pai ai te hononga hiko.
Ngā whakatūpato mō te PCB mā te hoahoa
Kia kaua ngā via e tata rawa ki ngā wāhanga, ki ētahi atu via rānei.
He wāhanga nui ngā Via o te hoahoa PCB, ā, me tūpato te whakanoho kia kore ai e pāngia ētahi atu wāhanga, ētahi atu via rānei. Ina tata rawa ngā via, ka tūpono te pakaru o te ara iahiko, ka kino rawa te PCB me ngā wāhanga hono katoa. E ai ki ngā wheako o Viasion, hei whakaiti i tēnei tūponotanga, me whakanoho ngā via kia 0.1 inihi te tawhiti atu i ngā wāhanga, ā, kaua ngā via e tata atu i te 0.05 inihi tetahi ki tetahi.
Kia kore ngā vias e taupatupatu ki ngā tohu, ki ngā papa rānei i ngā paparanga tata.
I te wā e hoahoa ana i ngā vias mō te papa hiko, he mea nui kia kaua ngā vias e taupatupatu ki ngā tohu, ki ngā papa rānei i runga i ētahi atu paparanga. Nā te mea ka taea e ngā vias te whakararu i ngā hiko, ka arahi ki ngā hapa o te pūnaha me te rahunga. E ai ki tā ā mātou kaihangarau, me whakanoho ngā vias ki ngā wāhi kāore he tohu, he papa rānei e tata ana hei karo i tēnei mōrearea. Hei tāpiri, ka whakarite kia kore ngā vias e pokanoa ki ētahi atu huānga o te PCB.
Whakaarohia ngā whakatauranga o te au me te pāmahana i te wā e hoahoa ana i ngā vias.
Me whakarite he pai te whakakikorua parahi o ngā vias kia pai ai te kawe i te au.
Me āta whakaaro ki te herenga o ngā vias, me te karo i ngā wāhi e uaua ai, e kore ai rānei e taea te arahi.
Kia mārama ki ngā whakaritenga hoahoa i mua i te whiriwhiri i ngā rahi me ngā momo.
Me whakatakoto ngā vias kia 0.3mm te iti rawa mai i ngā taha o te papa ki te kore e tohua tētahi atu mea.
Ki te mea ka whakatakotoria ngā vias tetahi ki tetahi, ka pakaru pea te papa ina keria, ina tukuna rānei.
He mea nui kia whakaarohia te ōwehenga āhuatanga o ngā vias i te wā e hoahoa ana, nā te mea ka pā pea ngā vias he nui te ōwehenga āhuatanga ki te pumau o te tohu me te mararatanga o te wera.
Me whakarite he nui ngā āputa o ngā via ki ētahi atu via, wāhanga me ngā taha papa, e ai ki ngā ture hoahoa.
Ina whakatakotoria ngā via kia takirua, kia nui ake rānei ngā tau, he mea nui kia tohatohahia kia ōrite kia pai ai te mahi.
Kia tūpato ki ngā via e tata rawa ana ki te tinana o te wae, nā te mea ka whakararuraru pea tēnei i ngā tohu e haere ana.
Te whakaaro ki ngā vias tata ki ngā waka rererangi.
Me whakanoho āta kia iti ai te haruru tohu me te haruru hiko.
Whakaarohia te whakanoho i ngā vias ki te paparanga kotahi me ngā tohu mēnā ka taea, nā te mea ka whakaitihia ngā utu vias, ka whakapai ake hoki i te mahi.
Whakaitihia te maha o ngā vias hei whakaiti i te uauatanga o te hoahoa me ngā utu.
Ngā āhuatanga miihini o te PCB mā roto i te kōhao
Te whānui o te poka
Me nui ake te whānui o ngā kōhao uru i te whānui o te pine wāhanga mono-mai, ā, me pupuri tonu he tawhiti. Ko te whānui iti rawa ka taea e te waea te uru atu ki ngā kōhao uru ka whakawhāitihia e te hangarau keri me te whakakikorua hiko. Ko te iti o te whānui o te kōhao uru, ko te iti o te wāhi i roto i te PCB, ko te iti ake o te kaha pirinoa, ā, ko te pai ake o te mahi auau-tiketike, engari ka nui ake te utu.
Papa puta-kōhao
Mā te papa e hono te hononga hiko i waenga i te paparanga o roto o te kōhao me te waea i runga i te mata (i roto rānei) o te papa hiko kua tāngia.
Te kaha o te poka
He kaha pirinoa kei roto i ia kōhao puta noa ki te whenua. Ka whakaroa, ka whakaiti rānei te kaha pirinoa puta noa i te kōhao i te taha e piki ake ana o te tohu matihiko, he mea kino tēnei mō te tuku tohu auau-tiketike. Koinei te pānga kino matua o te kaha pirinoa puta noa i te kōhao. Heoi, i ngā āhuatanga noa, he iti noa te pānga o te kaha pirinoa puta noa i te kōhao, ā, he iti noa iho—ko te iti o te diameter o te kōhao puta noa, ko te iti ake o te kaha pirinoa.
Te whakaawe o te kōhao
He mea noa te whakamahi i ngā kōhao mā roto i ngā PCB hei hono i ngā wāhanga hiko, engari ka pā mai anō hoki tētahi pānga taha kāore i te tūmanakohia: arā, te inductance.
Ko te aukume he āhuatanga o ngā kōhao e puta ana i te wa e rere ana te iahiko mā roto i aua kōhao, ā, ka puta he papa aukume. Ka taea e tēnei papa aukume te whakararuraru i ētahi atu hononga kōhao, ka puta he ngaronga tohu, he whakapōturi rānei. Ki te hiahia tātou ki te whakaiti i ēnei pānga, he mea nui kia mārama ki te mahi a te aukume me ngā mahi hoahoa ka taea e koe te mahi hei whakaiti i tōna pānga ki ō PCB.
Me nui ake te whānui o ngā kōhao uru i te whānui o te pine wāhanga mono-mai, ā, me pupuri tonu he tawhiti. Ko te whānui iti rawa ka taea e te waea te uru atu ki ngā kōhao uru ka whakawhāitihia e te hangarau keri me te whakakikorua hiko. Ko te iti o te whānui o te kōhao uru, ko te iti o te wāhi i roto i te PCB, ko te iti ake o te kaha pirinoa, ā, ko te pai ake o te mahi auau-tiketike, engari ka nui ake te utu.
