PCB kiʻekiʻe

Inā makemake ʻoe e hōʻemi i nā kumukūʻai, ʻo FR4 ka mea liʻiliʻi, ʻoi aku ka nui o nā mea kūʻai aku no ka hana ʻana i nā PCB kiʻekiʻe. akā, ʻoi aku ka palena o ka hana kiʻekiʻe o FR4, hoʻohana maʻamau mākou i kēia mau mea maka hou i ka hana ʻana i nā PCB HF.
Nā Papa Kaapuni Kūikawā Paʻi Laminate maka:
ROGERS: RO3003, RO4003C, RO4350B, RO5880, RO4450B, etc.

Panasonic: Megtron4, Megtron6, etc.
TUC: TUC862, 872SLK, 883, 933. ect...

ʻO nā hiʻohiʻona kumu o nā mea substrate kiʻekiʻe e like me kēia:
(1) Pono ka liʻiliʻi a paʻa ka dielectric mau (Dk). ʻO ka maʻamau, ʻoi aku ka liʻiliʻi ʻoi aku ka maikaʻi, ʻoi aku ka maikaʻi o ka hoʻouna ʻana o ka hōʻailona ma ke ʻano like ʻole me ke kumu huinahā o ka dielectric mau o ka mea. Hiki ke hoʻopaneʻe ka hoʻouna ʻana i ka hōʻailona.
(2) Pono ka liʻiliʻi o ka dielectric loss (Df), e pili ana i ka maikaʻi o ka lawe ʻana i ka hōʻailona. ʻO ka liʻiliʻi o ka poho dielectric, ʻoi aku ka liʻiliʻi o ka nalowale hōʻailona.
(3) ʻO ke koena o ka hoʻonui wela o ka pahu keleawe e like me ka hiki, no ka mea, ʻo ka like ʻole e hoʻokaʻawale i ka pahu keleawe i ka wā o ka hoʻololi ʻana o ke anuanu a me ka wela.
(4) ʻO ka haʻahaʻa haʻahaʻa o ka wai a me ka wai kiʻekiʻe e hoʻopili i ka dielectric mau a me ka dielectric nalowale ke pulu.
(5) Pono e maikaʻi ke kūpaʻa wela ʻē aʻe, ka pale kemika, ka ikaika o ka hopena, ka ikaika ʻili, a me nā mea ʻē aʻe.
Ma ka ʻōlelo maʻamau, hiki ke wehewehe ʻia ke alapine kiʻekiʻe e like me ke alapine ma luna o 1GHz. I kēia manawa, ʻo ka mea maʻamau i hoʻohana pinepine ʻia i nā substrates kaapuni ʻo fluorine dielectric substrates, e like me polytetrafluoroethylene (PTFE), i kapa ʻia ʻo Teflon, i hoʻohana mau ʻia ma luna o 5GHz. Eia kekahi, hoʻohana pū ʻia ʻo FR-4, hiki ke hoʻohana ʻia no nā huahana ma waena o 1GHz a me 10GHz.

noi:
ʻOiai ʻo ke alapine kiʻekiʻe o nā lako uila i kēia manawa he ʻano hoʻomohala, ʻoi aku ka nui o ka ulu ʻana o nā ʻupena uila a me nā kamaʻilio satelite, ke neʻe nei nā huahana ʻike i ka wikiwiki kiʻekiʻe a me ke alapine kiʻekiʻe, a ke neʻe nei nā huahana kamaʻilio i ka mana nui a me ka wikiwiki. ka hoʻoili leo, wikiō a me ka ʻikepili. ʻO ka standardization, no laila ke hoʻomohala ʻana i kahi hanauna hou o nā huahana e pono ai nā substrates kiʻekiʻe, a ʻo nā huahana kamaʻilio e like me nā ʻōnaehana ukali a me nā kelepona kelepona e loaʻa ai nā kahua kahua pono e hoʻohana i nā papa kaapuni kiʻekiʻe.
