ʻO ka Rogers Microwave RF Automotive Radar PCB
PCB alapine kiʻekiʻe no ka Radar Automotive Millimeter Wave
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 hana a me ka helu ʻana hana kiʻekiʻe o nā IoT. ʻO lākou nā kuhikuhi nui no ka hoʻomohala akamai a me ka pūnaewele o nā kahua kaʻa a me ka halihali honua. Hiki i ke kaʻa autonomous i lako me ka ʻenehana 5G ke hoʻokō i ka hoʻokele palekana a me ka ʻike holo ʻoluʻolu. ʻO ka hoʻouna wikiwiki ʻana i nā hōʻailona 5G e hāʻawi i ka ʻōnaehana kaʻa i ka manawa hou aʻe e hāʻawi i ka manaʻo a me ka hana ʻana, no laila e hōʻoiaʻiʻo ana i ka palekana o ka hoʻokele a me ka hāʻawi ʻana i kahi ʻike hoʻokele ʻoi aku ka maikaʻi.
ʻO ka hoʻohana nui ʻana i ka hoʻokele kaʻa kūʻokoʻa he mau mea ʻike radar nalu millimeter, kahi e hoʻohana nui ai i nā mea e like me RO3003G2TM, RO3003TM, RO4830TM, CLTE-MWTM, a pēlā aku. Hoʻohana nui ʻia lākou i ka radar nalu millimeter 77GHz a he paʻa loa ka dielectric constant a me ka ultra-low dissipation factor (ʻo ka dissipation factor o 0.001 e hoʻāʻo pinepine ʻia ma 10 GHz). I ka manawa like, ʻo ka hoʻolālā me ka ʻole o ka fiber aniani e hōʻemi hou aku i ka ʻokoʻa o ka dielectric constant kūloko i ka millimeter wave frequency band, ʻO ka hoʻopau ʻana i ka hopena fiberglass o ka hōʻailona e hoʻonui hou aku i ka paʻa o ka pae o ka sensor radar.
Me ka hoʻomohala ʻana o nā mea ʻike radar ma ka hui alapine 79 GHz (77-81 GHz), hiki i kā lākou bandwidth hōʻailona ākea ke hoʻomaikaʻi hou aku i ka hoʻonā o nā mea ʻike radar, hoʻonui i nā kihi scan, a hiki ke hoʻokō i ke kiʻi 4D.
ʻO Rogers PCB no ka mea ʻike radar nalu millimeter (e nānā i ke kiʻi 1 a me 2 no nā kikoʻī)
Papa kuhikuhi o ka papa kuhikuhi o ka (Rogers)RO3003™ PCB alapine kiʻekiʻe
(Rogers) RO3003™ ʻO nā substrates alapine kiʻekiʻe he mau mea hui PTFE i hoʻopiha ʻia me nā keramika, i hoʻohana ʻia no nā PCB i nā noi microwave kalepa a me RF. Hāʻawi ka hoʻolālā kū hoʻokahi i ka mea me ke kūpaʻa a hoʻopau i ka loli ʻanuʻu i ka dielectric constant o nā mea PTFE kumu maʻamau i ka mahana o ka lumi.
Loaʻa i nā substrates alapine kiʻekiʻe ʻo Rogers RO3003™ nā kūpaʻa dielectric paʻa (Dk: 0.00+/-0.04) a me ka mea hoʻoheheʻe (Df: 0.0010 ma 10GHz) ma nā mahana a me nā alapine like ʻole. He kūpono loa no nā noi e like me ka radar nalu millimeter automotive (77 GHz), nā ʻōnaehana kōkua hoʻokele holomua (ADAS) a me nā ʻōnaehana uila 5G (nalu millimeter).
Loaʻa i ka substrate RO3003™ ke kūpaʻa mechanical maikaʻi loa, e maʻalahi ai i nā mea hoʻolālā ke hoʻohana i nā mea me nā dielectric constants like ʻole i loko o kahi kaapuni papa hoʻokahi i ka wā e hoʻolālā ai i nā kaapuni multi-layer me ka ʻole o ka warping a i ʻole nā pilikia hilinaʻi. ʻO ke coefficient hoʻonui thermal o ka substrate RO3003™ ma ke kuhikuhi X/Y he 17/16 (ppm/℃). Ua like kēia waiwai me ke coefficient hoʻonui thermal o ke keleawe, no laila ʻo ka waiwai maʻamau o ka etching shrinkage (baking after etching) o ka mea he emi ma mua o 0.5mils/inch, e hōʻike ana i ka paʻa dimensional maikaʻi loa. ʻO ka CTE ma ke kuhikuhi Z he 25 (ppm/℃), a ʻoiai i nā wahi mahana koʻikoʻi, hiki i kēia mea ke hōʻoia i ke kūpaʻa o ka electroplated ma o nā lua.
Kiʻi 1: ʻO ka loli e pili ana i ka mahana o ka dielectric constant o RO3003 a me RO3035 laminates
E like me ka mea i hōʻike ʻia ma ke kiʻi ma luna, hōʻike nā dielectric constants o nā laminates RO3003 a me RO3035 i ke kūpaʻa maikaʻi me ka mahana. ʻAʻohe loli ʻanuʻu i ka dielectric constant ma ka mahana o ka lumi e like me ka PTFE glass fiber.
Kiʻi 2: Kumu hoʻoheheʻe o RO3003 a me RO3035.
Hōʻike ke kiʻi ma luna nei i ka hoʻokaʻawale ʻana o nā mea hoʻoheheʻe i nā laminates RO3003 a me RO3035. ʻAno hoʻāʻo RO3003-RO3035: IPC-TM-65025.5.5 Nā kūlana hoʻāʻo: 10 GHz 23 °C.

Ka hoʻohana ʻana o ka substrate alapine kiʻekiʻe (e nānā i ke kiʻi 3-1 no nā kikoʻī)
Nā lama maʻamau o nā substrates alapine kiʻekiʻe: ARLON substrate alapine kiʻekiʻe, TACONIC substrate alapine kiʻekiʻe, ROGERS substrate alapine kiʻekiʻe, Shengyi, Taiguang, Taiyao, Fushide, Wangling a me nā lama ʻē aʻe he nui. Waihona ʻoihana: Rogers, Taconic, F4B, TP-2, FR-4 a me nā substrates alapine kiʻekiʻe ʻē aʻe, hoʻolalelale wikiwiki i ka laʻana i loko o 24 mau hola.
ʻO Rogers, ma ke ʻano he mea hoʻolako honua nui o nā substrates kūikawā, he ʻoi aku ka nui o ka mākeke ma mua o 50% ma ka honua holoʻokoʻa a me 20 mau makahiki o ka ʻike ʻoihana ma ke kahua o ka antenna RF kahua kumu.
Ua haku ʻia nā mea alapine kiʻekiʻe a Rogers me nā moʻo 3000, moʻo 4000, moʻo 5000, a pēlā aku.
He loea ʻo RICHPCBA i ka hana ʻana i nā PCB RF microwave 2-68 papa a me nā huahana ʻē aʻe, me nā mea alapine kiʻekiʻe a Rogers i loaʻa koke, i lawe ʻia mai i loko o kā lākou pahu kumu me kahi laulā piha o nā hiʻohiʻona. Hāʻawi mākou i nā lawelawe laʻana PCB alapine kiʻekiʻe a Rogers, hana ʻana a me ka hana ʻana.
Nā kahua noi o nā PCB alapine kiʻekiʻe: hoʻohana nui ʻia i nā lako kamaʻilio, ka mana ʻoihana, nā hale akamai, nā lako mana i hoʻopilikino ʻia, nā mīkini lapaʻau a me nā mahina ʻē aʻe.
