PCB Radar Aunoa RF a Rogers Microwave
PCB auau-teitei mō te Radar Aunoa Ngaru Mirimita
Ko te 5G me te haereere pūkoro he hua o te whakaurunga hohonu o te umanga motuka me ngā hangarau mōhiohio o te whakatupuranga hou pēnei i te whakawhitiwhiti kōrero, te mohio horihori me te rorohiko mahi-teitei o ngā IoT. Koinei ngā huarahi matua mō te whanaketanga atamai me te whatunga o ngā mara motuka me te kawe waka o te ao. Ka taea e te waka motuhake kua whakauruhia ki te hangarau 5G te whakatutuki i te taraiwa haumaru me te wheako eke whakamarie ake. Mā te tuku tohu 5G tere ake ka nui ake te wā o te pūnaha waka ki te tuku urupare me te tukatuka, kia pai ai te haumaru o te taraiwa me te whakarato i te wheako taraiwa pai ake.
Ko te whakamahinga matua o te taraiwa motuhake ko ngā pūoko radar ngaru mirimita, e whakamahi ana i ngā rauemi pēnei i te RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, me ētahi atu. He whānuitia te whakamahinga o ēnei i roto i te radar ngaru mirimita 77GHz, ā, he tino pumau te pūmau dielectric me te tauwehenga marara tino iti (he tauwehenga marara o te 0.001 e whakamatautauria ana i te 10 GHz). I taua wā anō, ko te hanganga kāore he muka karāhe ka whakaiti ake i te rerekētanga o te pūmau dielectric ā-rohe i roto i te roopu auau ngaru mirimita. Mā te whakakore i te pānga muka karāhe o te tohu ka whakanui ake i te pumau ā-wāhanga o te pūoko radar.
I te whanaketanga o ngā pūoko radar i te roopu auau 79 GHz (77-81 GHz), ka taea e te whānuitanga o ngā tohu te whakapai ake i te taumira o ngā pūoko radar, te whakanui ake i ngā koki matawai, tae atu ki te whakatutuki i te whakaahua 4D.

Ripanga tawhā whakatakotoranga o te (Rogers)RO3003™ PCB Auau-teitei
(Rogers) Ko ngā papa auau teitei RO3003™ he rauemi hiato PTFE kua whakakiia ki ngā uku, e whakamahia ana mō ngā PCB i roto i ngā tono ngaruiti arumoni me ngā tono RF. Mā te hoahoa ahurei ka pumau te rauemi, ā, ka whakakorea te huringa taahiraa i roto i te pūmau dielectric o ngā rauemi PTFE whānui i te pāmahana rūma.
Kei ngā papaaho auau teitei a Rogers RO3003™ he pūmau tonu ngā pūmau dielectric (Dk: 0.00+/-0.04) me te tauwehenga marara (Df: 0.0010 i te 10GHz) i ngā pāmahana me ngā auau rerekē. He tino pai mō ngā tono pēnei i te radar ngaru mirimita motuka (77 GHz), ngā pūnaha āwhina taraiwa matatau (ADAS) me te hanganga ahokore 5G (ngaru mirimita).
He tino pai te pumau ā-mīhini o te papa RO3003™, e wātea ai mō ngā kaihoahoa te whakamahi i ngā rauemi me ngā pūmau dielectric rerekē i roto i te ara iahiko papa-kotahi i te wā e hoahoa ana i ngā ara iahiko papa-maha me te kore e piko, e raru rānei te pono. Ko te tauwehenga whānui wera o te papa RO3003™ i te ahunga X/Y ko 17/16 (ppm/℃). He rite tēnei uara ki te tauwehenga whānui wera o te parahi, nō reira ko te uara noa o te whakahekenga whakairo (tunu i muri i te whakairo) o te rauemi he iti iho i te 0.5mils/inihi, e whakaatu ana i te pumau āhuahanga tino pai. Ko te CTE i te ahunga Z ko 25 (ppm/℃), ā, ahakoa i roto i ngā taiao pāmahana kino, ka taea tonu e tēnei rauemi te whakarite i te pumau o te whakakikoruatia hiko mā roto i ngā kōhao.
Pikitia 1: Te rerekētanga e pā ana ki te pāmahana o te pūmau dielectric o ngā papa RO3003 me RO3035
E ai ki te pikitia i runga ake nei, he pai te pumau o ngā pūmau dielectric o ngā paparanga RO3003 me RO3035 ki te pāmahana. Kāore he huringa takahanga i roto i te pūmau dielectric i te pāmahana rūma pērā i te muka karāhe PTFE.
Ahua 2: Tauwehenga marara o RO3003 me RO3035.
E whakaatu ana te pikitia i runga ake nei i te tohatoha o ngā āhuatanga memeha i roto i ngā paparanga RO3003 me RO3035. Tikanga whakamātautau RO3003-RO3035: IPC-TM-65025.5.5 Ngā tikanga whakamātautau: 10 GHz 23 °C.
