4 Layer ENIG FR4+R04350 Huihui Lamination PCB
ʻO FR4 + Rogers e hoʻohui ana i ka lamination PCB hana pilikia
ʻO kekahi o nā paʻakikī koʻikoʻi i nā noi RF / microwave pehea e hōʻoia ai i ka hoʻomanawanui maoli ʻana i loko o nā hoʻolālā hoʻolālā, i hiki ai ke hoʻokō i ke alapine hana i makemake ʻia.ʻO kekahi o nā luʻi nui loa i ka hoʻolālā lamination o nā ʻano hoʻoheheʻe hui ʻia ʻo ka loaʻa ʻana o ka mānoanoa like ʻole ma waena o nā panela like ʻole a i ʻole ma waena o nā ʻāpana like ʻole.Ma muli o ke ʻano o nā ʻano mea substrate like ʻole, aia nā ʻano o nā ʻano pepa semi-cured.
ʻOkoʻa ʻo Rogers mai ka PCB epoxy resin.ʻAʻohe kīʻaha aniani ma ka waena a ʻo ia ka seramika e pili ana i ke alapine kiʻekiʻe.Ma nā alapine kaapuni ma luna o 500MHz, ua hoʻemi nui ʻia ka nui o nā mea i loaʻa i ka ʻenekini hoʻolālā.Hiki ke hana maʻalahi ʻia nā mea ʻo Rogers RO4350B i nā ʻāpana hoʻolālā ʻenehana RF, e like me ka hoʻohālikelike ʻana i ka pūnaewele, ka mana impedance line transmission, a me nā mea ʻē aʻe.ʻO ka dielectric mau o ka hoʻololi ʻana o ka mahana ʻaneʻane ka haʻahaʻa loa i ka mea like.Paʻa loa ka permittivity ma 3.48 ma kahi ākea ākea.3.66.Nā ʻōlelo aʻoaʻo hoʻolālā keleawe keleawe Lopra e hōʻemi i ka nalowale o ka hoʻokomo.Hana kēia i ka mea kūpono no nā noi broadband.
Nā pōmaikaʻi o ka hui ʻana i ka Lamination High Frequency PCB
1. High-frequency PCB he kiʻekiʻe kiʻekiʻe a me ka hoʻomaikaʻi hōʻailona.Hāʻawi ia i kahi alapine mai 500MHz a 2GHz, kūpono no nā hoʻolālā kiʻekiʻe.
2. ʻO ka hoʻohanaʻana i ka papa honua e hoʻonui i ka maikaʻi o ka hōʻailona a ho'ēmi i ka nalu electromagnetic.
3. E ho'ēmi i ka impedance kaapuni a hāʻawi i ka hopena pale.
4. Ma ka hōʻemi ʻana i ka mamao ma waena o ka mokulele a me ka papa kuhikuhi, hiki ke pale ʻia ka crosstalk
