RF PCB - Nā Papa Kaapuni Puni pinepine. I nā huaʻōlelo maʻamau, manaʻo ka ʻoihana PCB i kahi papa kaapuni RF kahi PCB alapine kiʻekiʻe e hana ma luna o 100MHz.
Ma loko o ka papa pinepine lekiō, ʻo kekahi mea ma luna o 2GHz kahi MicBack PCB. Kahi a lākou e hana ai. Hoʻohālikelike ʻia nā PCB microwave e like me kekahi papa kaapuni RF e hana ana ma luna o 2GHz.
Hoʻohana ʻia nā papa kaapuni RF a me nā PCB Pōkohu no nā hōʻailona kamaʻilio i kekahi noi e koi ana i ka loaʻa a me ka lawe ʻana i nā lekiō lekiō. ʻO kahi laʻana, kekahi mau noi maʻamau nā kelepona paʻalima a me nā hoʻonohonoho radar. ʻO kekahi o nā mea hoʻolako i nā mea laminate / dielectric a mākou e hoʻohana nei: Isola, Nelco, Rogers & Taconic.
ʻO ka hybrid print circuit circuit board (PCB) multilayer kahi PCB e hoʻohana ana i nā mea like ʻole me ka manaʻo e hoʻonui i ka hana uila a me ka hoʻomaikaʻi ʻana i ka hilinaʻi ʻōnaehana i pili i nā noi RF kiʻekiʻe pinepine. ʻO ka pahuhopu nui loa ke hana ʻana i kēia ʻano PCB ke hoʻokele nei i ka coefficient ʻokoʻa o ka hoʻonui thermal (CTE) waiwai o nā mea kaapuni dissimilar ma ka hana PCB a me ka hui ʻana o ka hui.
ʻO ka maʻamau o kēia mau hoʻolālā me ka hui pū o nā mea FR-4 a me nā laminate PTFE i hiki ai i ka mea hoʻolālā ke hoʻokaʻawale i nā hana RF a me nā hana RF ma ka PCB like e hiki ai ke hoʻemi i ka paepae wāwae o ka hāmeʻa a me nā koina.
