Tirotiro i te Whakapiri Tūhono 3D i roto i te PCBA: Te Raina Tuatahi o te Tiaki Kounga Tūhono
I roto i te umanga hanga hiko e tere whanake ana, kua noho te kounga PCBA hei tohu matua mō te whakataetae hua. Ahakoa he whakawhitiwhiti kōrero 5G, he hikohiko motuka, he taputapu hauora me te rererangi rānei me ngā whakaritenga pono teitei, ko te kounga whakarewa pumau me te pumau te turanga mō te whakarite i te mahi. Ko te tīmatanga o te whakarewatanga kāore e tīmata mā te whakarewatanga anō, engari mā te tukanga tā whakapiri whakarewa.
Nā konei, ko te Mīhini Tirotiro Whakapiri Whakakotahi 3D (3D SPI), te taputapu tirotiro aunoa tuatahi i muri i te tānga whakapiri whakakotahi, kua noho hei tūranga nui i roto i te raina whakaputa SMT atamai. Ehara i te mea he taputapu kaha anake mō te kimi i ngā hapa tā, engari he "kaitiaki whāinga" nui hoki mō te whakarite i te hua whānui me te whakapai ake i te ōritetanga o te hua.
1. Te Mātāpono Mahi o te 3D SPI: Te Whakakite i te "Teitei"
Ko ngā taputapu tirotiro 2D tuku iho ka taea anake te kite i te āhua o te mata o te tānga whakapiri whakapiri, ā, kāore e taea te whakamahi i ngā āhuatanga matua pēnei i te matotoru me te rōrahi. Ka taea e te mīhini tirotiro whakapiri whakapiri 3D te mahi whakaahua 3D tūturu o te āhua o te whakapiri whakapiri i runga i ia papa mā te hangarau whakaata mārama hanganga + tātari ā-wāhanga stereo, ā, ka kitea i runga i te rahinga ngā tawhā matua e whai ake nei:
- Teitei o te whakapiri konukōre (Teitei)
- Te rōrahi o te whakapiri konukōre (Rōrahi)
- Te kapinga o te papa (Hohenga)
- Ngā hapa pēnei i te whakapiri whakapiri, te piriti, te korenga o te whakapiri, me te nui rawa o te whakapiri
Mā te tere matawai i te taumata 10ms, ka taea e te 3D SPI te whakatutuki i te tirotiro tuihono 100% mō ia PCB, ā, he hononga kati kei te mīhini SMT pick-and-place, e whakahoki ana i ngā raraunga i te wā tūturu hei whakarite kei roto te kounga tā i te āhua ka taea te whakahaere.
2. Ngā Tohu Matua e Whakaatu Ana i te Kounga o ngā Taputapu
Te Tika o te Kitenga me te Āheitanga ki te Whakahoki
Me whai tika auau te taputapu SPI kounga teitei o te ±1µm me te hapa ine rōrahi i roto i te ±2%...
Tere Tukatuka Whakaahua me te Arorau Atamai
Whakamahia he hoahoa rorohiko whakarara FPGA me te GPU, me te whakakotahitanga o tētahi pūnaha tukatuka whakaahua ako hōhonu...
Pūnaha Āwhina Pūmanawa me te Aroturuki
He atanga reo rua Hainamana/Ingarihi, e tautoko ana i te kawemai Gerber, ngā pūrongo SPC, me te whai i ngā MES...
Te Whakarerekētanga o te Hoahoa Hanganga me te Tukanga
Tinana konumohe koranu ā-ahumahi, he pai mō te tirotiro i ngā wāhanga 0201, BGA, QFN, ngā rahi PCB rerekē...
3. Mai i te "Tirotiro" ki te "Mana Whakahaere": Te Whakaaturanga o ngā Painga Tuturu
- Whakapai ake i te reiti tohu mō te tuhinga tuatahi mā te kimi wawe i ngā hapa
- Whakaitihia te mahi anō me te para mā te urupare wā-tūturu me te whakatikatika tukanga
- Whakapai ake i te māramatanga mā te whakamahi i ngā raraunga whakapiri tūhono mō ia papa me te whai i ngā raraunga
- Whakahohehia te mana kounga porowhita-kati e hono ana ki te tukanga SMT
- Whakapai ake i te mahi mā te whakakapi i te tirotiro ā-ringa ki te aunoatanga atamai
4. Te Kaha o te Urutau Ahumahi mō te Hanganga Tino Pai
E whakamahia whānuitia ana ngā pūnaha SPI 3D i roto i ngā rāngai pono-nui tae atu ki:
- Ngā hikohiko motuka
- Ngā taputapu hauora me te tiaki hauora
- Ngā teihana turanga waea
- Te whakahaere ahumahi me te rererangi
He tino pai mō ngā PCB paparanga maha me ngā PCB HDI, te BGA/CSP tino pai, me te whakaputa rahinga me ngā whāinga kore-hapa.
Whakamutunga: Ka tīmata te kounga teitei mai i te taahiraa tuatahi
Ko ia taahiraa o te hanga PCBA e whakaata ana i te whakapau kaha ki te kounga. Ahakoa he tīmatanga noa te tānga whakapiri whakarewa, he nui te pānga ki te kounga whakarewa whakamutunga. Ko te whiriwhiri i tētahi pūnaha SPI 3D whai hua, pumau, me te atamai ko te hanga i te arai whakapumautanga kounga tuatahi "kitea".
Haunga te mahi, me whai pono ngā kaihanga mō te wā roa me te tautoko atamai. Mā te taputapu tirotiro tika, ehara i te mea ka "kite noa i ngā hapa" engari ka taea hoki e koe te "whakahaere i ngā mōrearea" me te "matapae i ngā au o te kounga" — te hanga uara pumau.
