ʻO Rogers Microwave RF Automotive Radar PCB
ʻO PCB kiʻekiʻe no ka Millimeter Wave Automotive Radar
ʻO 5G a me ka huakaʻi kelepona nā huahana o ka hoʻohui hohonu ʻana o ka ʻoihana kaʻa me nā ʻenehana ʻike hanauna hou e like me ke kamaʻilio ʻana, ka naʻauao akamai a me ka helu helu kiʻekiʻe o nā IoT. ʻO lākou nā kuhikuhi nui no ka hoʻomohala ʻana i ka naʻauao a me ka hoʻomohala ʻana i ka ʻoihana kaʻa honua a me nā kahua kaʻa. Hiki i ke kaʻa autonomous i lako me ka ʻenehana 5G ke hoʻokō i ka hoʻokele palekana a ʻoi aku ka ʻoluʻolu o ka holo kaʻa. ʻO ka wikiwiki o ka hōʻailona hōʻailona 5G e hāʻawi i ka ʻōnaehana kaʻa i ka manawa hou e hāʻawi i ka manaʻo a me ka hoʻoponopono ʻana, a laila e hōʻoiaʻiʻo ai i ka palekana kaʻa a hāʻawi i kahi ʻike hoʻokele maikaʻi.
ʻO ka noi nui i ka hoʻokele autonomous ka millimeter wave radar sensors, ka mea nui e hoʻohana i nā mea e like me RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, a me nā mea ʻē aʻe. kumu (ke ho'āʻo pinepine ʻia kahi mea hoʻopau o 0.001 ma 10 GHz). I ka manawa like, ʻo ka hale me ke aniani ʻole e hoʻemi hou i ka hoʻololi ʻana o ka dielectric kūloko i loko o ka pahu alapine hawewe millimeter, ʻo ka hoʻopau ʻana i ka hopena fiberglass o ka hōʻailona e hoʻonui hou i ka pae paʻa o ka ʻike radar.
Me ka hoʻomohala ʻana o nā mea ʻike radar i ka 79 GHz frequency band (77-81 GHz), hiki i kā lākou bandwidth hōʻailona ākea ke hoʻomaikaʻi hou i ka hoʻonā ʻana o nā mea ʻike radar, hoʻonui i nā kihi scanning, a hiki i ka hoʻokō ʻana i ke kiʻi 4D.
ʻO Rogers PCB no ka millimeter wave radar sensor (e nānā i ka helu 1 a me 2 no nā kikoʻī)
Papa kuhikuhi kiko'ī o (Rogers) RO3003™ PCB kiʻekiʻe-frequency
(Rogers) RO3003 ™ ʻO nā substrate kiʻekiʻe kiʻekiʻe he PTFE composite material i hoʻopiha ʻia me nā seramika, i hoʻohana ʻia no nā PCB i ka microwave kalepa a me nā noi RF. Hāʻawi ka hoʻolālā kūʻokoʻa i ka mea me ka paʻa a hoʻopau i ka hoʻololi ʻana i ka hoʻololi ʻana i ka dielectric mau o nā mea PTFE kumu nui ma ka lumi wela.
Loaʻa i ka Rogers RO3003™ mau substrate alapine kiʻekiʻe nā dielectric paʻa (Dk: 0.00+/-0.04) a me ka mea hoʻopau (Df: 0.0010 ma 10GHz) i nā wela a me nā alapine like ʻole. He kūpono loa no nā noi e like me ka millimeter wave radar (77 GHz), nā ʻōnaehana kōkua hoʻokele kiʻekiʻe (ADAS) a me nā ʻōnaehana uila 5G (nā nalu millimeter).
Loaʻa i ka RO3003 ™ substrate ke kūpaʻa mechanical maikaʻi loa, e maʻalahi i nā mea hoʻolālā ke hoʻohana i nā mea me nā mea hoʻomau dielectric like ʻole i loko o kahi kaapuni hoʻokahi i ka wā e hoʻolālā ai i nā kaapuni multi-layer me ka ʻole o ka hoʻopiʻi ʻana a i ʻole nā pilikia hilinaʻi. ʻO ka helu hoʻonui wela o RO3003 ™ substrate ma ke kuhikuhi X/Y he 17/16 (ppm/℃). Ua like kēia waiwai me ka koena hoʻonui wela o ke keleawe, no laila, ʻoi aku ka liʻiliʻi o ka waiwai maʻamau o ka etching shrinkage (baking after etching) o ka mea ma mua o 0.5mils/inihi, e hōʻike ana i ke kūpaʻa maikaʻi loa. ʻO ka CTE ma ke kuhikuhi Z he 25 (ppm/℃), a i loko o nā wahi wela koʻikoʻi, hiki i kēia mea ke hōʻoia i ka paʻa o ka electroplated ma nā lua.
Kiʻi 1: ʻO ka hoʻololi ʻana i ka wela o ka dielectric mau o RO3003 a me RO3035 laminates
E like me ka mea i hōʻike ʻia ma ka kiʻi ma luna, ʻo nā mea hoʻomau dielectric o nā laminates RO3003 a me RO3035 e hōʻike i ka paʻa maikaʻi me ka mahana. ʻAʻohe hoʻololi ʻanuʻu i ka dielectric mau ma ka lumi wela e like me ka PTFE aniani fiber.
Kiʻi 2 : Ke kumu hoʻopau o RO3003 a me RO3035.
Hōʻike ka helu i luna i ka māhele ʻana o nā mea hoʻopau i nā laminates RO3003 a me RO3035. RO3003-RO3035 Ke ala hoʻāʻo: IPC-TM-65025.5.5 Kūlana hoʻāʻo: 10 GHz 23 °C.
Palapala noi
No ka hoʻohana ʻana i ka substrate kiʻekiʻe (e ʻike i ke kiʻi 3-1 no nā kikoʻī)
Nā hōʻailona maʻamau o nā substrate kiʻekiʻe: ARLON kiʻekiʻe-frequency substrate, TACONIC kiʻekiʻe-frequency substrate, ROGERS kiʻekiʻe-frequency substrate, Shengyi, Taiguang, Taiyao, Fushide, Wangling a me nā mea'ē aʻe he nui. Hui Pūʻulu: Rogers, Taconic, F4B, TP-2, FR-4 a me nā mea hoʻopili alapine kiʻekiʻe ʻē aʻe, wikiwiki ka laʻana i loko o 24 mau hola.
ʻO Rogers, ma ke ʻano he alakaʻi alakaʻi honua o nā substrates kūikawā, loaʻa iā ia kahi mākeke ma luna o 50% a puni ka honua a me 20 mau makahiki o ka ʻike ʻoihana ma ke kahua o ka base station antenna RF.
ʻO nā mea kiʻekiʻe-frequency Rogers he 3000 series, 4000 series, 5000 series, etc.
Hoʻokumu ʻo RICHPCBA i ka hana ʻana i ka 2-68 layer microwave RF PCBs a me nā huahana ʻē aʻe, me nā mea kiʻekiʻe-frequency Rogers i hiki ke loaʻa, lawe ʻia i loko o kā lākou waihona mua me nā ʻano hiʻohiʻona piha. Hāʻawi mākou iā Rogers kiʻekiʻe-frequency PCB sampling, hana a me ka lawelawe lawelawe.
Nā kahua noi o nā PCB kiʻekiʻe: hoʻohana nui ʻia i nā lako kamaʻilio, ka mana ʻoihana, nā hale akamai, nā lako mana maʻamau, nā mīkini lapaʻau a me nā kahua ʻē aʻe.
Radar kaʻa; GPS antenna; Pūnaehana kamaʻilio kelepona: hoʻonui mana a me ka antenna; Antenna i kau ʻia no ke kamaʻilio uea; Satellite no ka hoʻouna pololei ʻana; Pūnaehana uwea no ka hoʻopili ʻana i ka ʻikepili; Heluhelu mika mamao a me ka papa mana, etc;
