Papa Uku DPC: he kōwhiringa pai mō te tākai i ngā maramara LiDAR motuka
Ko te mahi a te LiDAR (Te Kitenga Mārama me te Rangi) he tuku i ngā tohu reera whero-whero me te whakarite i ngā tohu whakaata i muri i te tūtaki ki ngā arai me ngā tohu kua tukuna, kia whiwhi ai i ngā mōhiohio pēnei i te tūranga, te tawhiti, te aronga, te tere, te āhua, me te āhua o te ūnga. Ka taea e tēnei hangarau te karo i ngā arai, te whakatere motuhake rānei. Hei pūoko tino tika, e kiia whānuitia ana te LiDAR hei mea matua ki te whakatutuki i te taraiwa motuhake taumata teitei, ā, kei te piki haere tōna hiranga.
Ko ngā pūtake mārama taiaho te mea tino rongonui i roto i ngā wāhanga matua o te LiDAR motuka. I tēnei wā, ko te pūtake mārama VCSEL (poutū āputaputa mata taiaho) kua waiho hei whiringa pai mō te LiDAR totoka-ā-ira me te LiDAR uira i roto i ngā waka nā te iti o te utu hanga, te pono nui, te iti o te koki wehewehe, me te ngāwari o te whakauru 2D. Ka taea e te maramara VCSEL te whakatutuki i te tawhiti kite roa ake, te tika o te tirohanga teitei ake, me te tutuki i ngā paerewa haumaru kanohi pakari i roto i te LiDAR totoka-ā-ira motuka. Hei tāpiri, ka taea e rātou te Flash LiDAR te whakatutuki i tētahi tirohanga ngāwari ake, whānui ake hoki, ā, he nui ngā painga utu.
Kua noho ngā papa uku hei rauemi takai maramara tino pai mō ngā tono LiDAR motuka.
He nui te kawe wera o ngā papa uku DPC (Direct Copper Plating), he teitei te whakamarumaru, he teitei te tika o te ara iahiko, he teitei te maeneene o te mata, ā, he tauwehenga whānui wera e rite ana ki te maramara. Ka whakaratohia hoki e rātou he hononga poutū hei whakatutuki i ngā whakaritenga takai o VCSEL.
1. He tino pai te tohatoha wera
He hononga poutū tō te papa uku DPC, ka hangaia he hongere kawe hiko ā-roto motuhake. Nā te mea he ārai wera, he kawe hiko wera hoki ngā uku, ka taea e rātou te wehe i te wera hiko me te whakaoti rapanga i te raru marara wera o ngā maramara VCSEL.
2. Te pono nui
He tino teitei te mātotoru o te mana o ngā maramara VCSEL, ā, ko te kore e ōrite te whānui o te wera i waenga i te maramara me te papa ka arahi pea ki ngā raruraru ahotea. He tino hototahi te tauwehenga whānui wera o ngā papa uku ki te VCSEL. Hei tāpiri, ka taea e ngā papa uku DPC te whakauru i ngā anga whakarewa me ngā papa uku hei hanga i tētahi kōhao hiri, me te hanganga kiato, kāore he paparanga hononga waenga, ā, he tino piri te hau.
3. Hononga poutū
Me tāuta he karu whakaata ki runga ake i te maramara mō te takai VCSEL, nō reira me whakatū he kōhao 3D ki roto i te papa. Ko ngā papa uku DPC he painga o te hononga poutū me te pono teitei, e tika ana mō te hononga eutectic poutū.
I roto i te horopaki o te whanaketanga o ngā motuka atamai, kei te piki haere te hiranga o ngā rauemi uku i roto i te whanaketanga atamai o ngā waka hiko hou. Hei turanga mō te puranga hangarau katoa, he mea nui te auahatanga tonu i roto i te hangarau rauemi hei tautoko i te whanaketanga whai hua o te umanga katoa.
