He aha ka papa kuhikuhi papa Rogers PCB?

Hāʻawi ka Rogers RO4350B i nā mea ʻenekinia RF PCB e hoʻolālā maʻalahi i nā kaʻa, e like me ka pili pūnaewele a me ka mana impedance o nā laina hoʻouna.Ma muli o kāna mau hiʻohiʻona dielectric haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o ka mea RO4350B ma mua o nā mea kaapuni maʻamau i nā noi kiʻekiʻe.ʻO ka hoʻololi ʻana o ka permittivity me ka mahana ʻaneʻane ka haʻahaʻa loa ma waena o nā mea like, a ʻo kona ʻae ʻana ua kūpaʻa nō hoʻi ma kahi ākea ākea, me ka manaʻo hoʻolālā o 3.66.Hoʻemi ʻo LoPra™ Copper foil i ka poho hoʻokomo.Hana kēia i ka mea kūpono no nā noi broadband.

ʻO ka papa PCB Rogers: mea keramika kiʻekiʻe pinepine PCB moʻo hoʻohālikelike:

RO3000 moʻo: PTFE kaʻapuni mea e pili ana i ka ceramic hoʻopiha, nā kumu hoʻohālike: RO3003, RO3006, RO3010, RO3035 kiʻekiʻe-frequency laminate.

RT6000 moʻo: e pili ana i ka ceramic piha PTFE kaʻapuni mea, i hoʻolālā ʻia no nā uila uila a me nā kaʻa microwave e koi ana i ka ʻae kiʻekiʻe.ʻO nā kumu hoʻohālike: RT6006 permittivity 6.15, RT6010 permittivity 10.2.

ʻO ka moʻo TMM: nā mea i hui ʻia e pili ana i ka ceramic, hydrocarbon, thermosetting polymer, model: TMM3, TMM4, TMM6, TMM10, TMM10i, TMM13i., etc.
Hiki ke hoʻoneʻe ʻia ka mea RO4003 me kahi kāhili nylon maʻamau.ʻAʻole koi ʻia kahi lawelawe kūikawā ma mua o ka electroplating keleawe me ka ʻole o ka uila.Pono e mālama ʻia ka pā me ke kaʻina hana epoxy/aniani maʻamau.Ma keʻano laulā, ʻaʻole pono e wehe i ka lua no ka mea ʻaʻole hiki ke wehe maʻalahi ka ʻōnaehana resin TG kiʻekiʻe (280 ° C + [536 ° F]) i ka wā o ke kaʻina wili.Inā hoʻokumu ʻia ka ʻili e ka hana wili ʻana, hiki ke hoʻoneʻe ʻia ka resin me ka hoʻohana ʻana i ka pōʻaiapili plasma CF4/O2 maʻamau a i ʻole ke kaʻina hana ʻelua alkaline permanganate.

Hoʻohālikelike ʻia nā koi kuke o ka mea RO4000 me nā epoxy/aniani.Ma keʻano laulā, ʻaʻole pono nā mea hana e hoʻomoʻa ʻole i nā papa epoxy/aniani e kuke i nā PCB RO4003.No ka hoʻokomo ʻana i ke aniani epoxy/baked ma ke ʻano he hana maʻamau, paipai mākou i ka kuke ʻana ma 300°F, 250°F (121°C-149°C) no 1 a 2 mau hola.ʻAʻole loaʻa i ka RO4003 nā mea pale ahi.Ma ka hoʻomaopopo ʻana, hiki i nā papa i hoʻopaʻa ʻia i loko o nā ʻāpana infrared (IR) a i ʻole ka hana ʻana i nā wikiwiki hoʻouna haʻahaʻa loa e hiki ke piʻi i nā mahana ma mua o 700°F (371 °C);Hiki iā RO4003 ke hoʻomaka i ke ahi ma kēia mau wela kiʻekiʻe.ʻO nā ʻōnaehana e hoʻohana mau ana i nā ʻenehana reflux infrared a i ʻole nā ​​​​mea hana ʻē aʻe e hiki ke hōʻea i kēia mau wela kiʻekiʻe e pono e mālama i nā mea e pono ai e hōʻoiaʻiʻo ʻaʻohe pilikia.

ʻO Ro3003 kahi papa papa Rogers PCB i hoʻopiha ʻia i ka PTFE composite no ka microwave kalepa a me nā noi RF.Hoʻolālā ʻia kēia ʻano huahana e hāʻawi i ke kūpaʻa uila a me ka mechanical ma ke kumu kūʻai hoʻokūkū.Loaʻa iā Rogers Ro3003 kahi kūpaʻa permittivity maikaʻi loa ma luna o ka pae wela a pau, me ka hoʻopau ʻana i nā loli permittivity i hana ʻia ke hoʻohana ʻia nā mea aniani PTFE ma ka lumi wela.Eia kekahi, loaʻa i nā laminates Ro3003 nā helu poho ma lalo o 0.0013 a 10 GHz.
