Hana ʻia ʻo Rogers 5880 laminate me nā mea kiʻekiʻe kiʻekiʻe a hilinaʻi hoʻi e like me Rogers, kahi e lanakila ai ʻo Rogers i nā makana koʻikoʻi mai nā mea hana kiʻekiʻe. I kekahi mau hoʻolālā, he mea nui nā waiwai dielectric o PCB. Inā he kiʻekiʻe, RF, microwave a i ʻole kelepona, ʻo ka hoʻokele mana ke kī. E ʻike ʻoe ʻoi aku ka pono o nā hiʻohiʻona dielectric o ka papa kaapuni i ka prototype ma mua o nā mea i hāʻawi ʻole ʻia e ka FR-4 maʻamau. ʻIke mākou. ʻO kēia ke kumu e hoʻonui ai mākou i ka pcbexpress me nā mea dielectric rogers5880. ʻO kēia mau mea dielectric haʻahaʻa haʻahaʻa haʻahaʻa e ʻoi aku ka hana kiʻekiʻe no ke koi ʻana i nā prototypes PCB.

No ke aha e hoʻohana ai i ka mea dielectric Rogers?
ʻO ka mea FR-4 ka maʻamau maʻamau o PCB pani, hiki ke hoʻokō i kahi kaulike kūpono ma waena o ke kumukūʻai, ka mana hana, ka hana uila a me ka lōʻihi. Akā inā ʻo nā hiʻohiʻona uila a me ka hana holomua ke kumu o kāu hoʻolālā, ʻo Rogersmaterials kāu koho maikaʻi loa no ka mea:
E hoemi i ka poho dielectric
Haʻahaʻa poho hoʻohana mana hōʻailona
Nui DK (dielectric mau) (2.55-10.2)
Hana kaapuni haʻahaʻa
Nā noi wahi hoʻokuʻu ea haʻahaʻa

Mea uila dielectric
ʻO ka mea dielectric kahi mea me ka conductivity maikaʻi ʻole, i hoʻohana ʻia ma ke ʻano he insulating layer i ka hoʻolālā PCB. ʻO kekahi o ka dielectric he mika, a ʻo kekahi o ka dielectric he mica, metal oxide, a me ka plastic. ʻO ka haʻahaʻa o ka poho dielectric (ka ikehu i nalowale i ke ʻano o ka wela), ʻoi aku ka maikaʻi o ka mea dielectric. Inā kiʻekiʻe loa ka volta o ka mea dielectric, ʻo ia hoʻi, i ka wā e ikaika loa ai ke kahua electrostatic, hoʻomaka koke ka mea e hana i kēia manawa. Kapa ʻia kēia ʻano he dielectric breakdown.
Nā waiwai o rtduroid5880
Loaʻa haʻahaʻa haʻahaʻa lilo manawa no kekahi uila hoʻoikaika ʻia PTFE mea
Haʻahaʻa haʻahaʻa haʻahaʻa
Isotropy
Hana uila me ka pinepine like
ʻO ke kūpaʻa kemika maikaʻi loa, me nā solvents a me nā reagents no ka paʻi ʻana a me ka uhi ʻana
Kaiapuni hoalohaloha
Ma mua o ka impregnation (pre preg)
ʻO ka emi ʻana o ka “pre impregnated composite fiber” a me ka hana ʻana o PCB, pre PregS, e hoʻopilikia i nā ʻano hana o ka papa kaapuni paʻi. ʻO kahi huaʻōlelo i hoʻohana ʻia i ka ʻoihana hana PCB e wehewehe i ka mea o ka ʻāpana adhesive i hoʻohana ʻia e hoʻohui i nā papa, multilayer PCB.
Rtduroid5880 kiʻekiʻe alapine laminate mai Rogers
Hoʻohana ʻo Rogers5880 kiʻekiʻe pinepine laminate series PTFE composite i hoʻoikaika ʻia i ke aniani fiber. Kuhi ʻia kēia mau microfibers e hoʻonui i nā pono o ka loaʻa ʻana o ka fiber a hāʻawi i ke kuhikuhi koʻikoʻi no nā mea hana kaapuni a me nā noi hoʻohana hope. ʻO ka dielectric mau o kēia mau laminates kiʻekiʻe ka haʻahaʻa loa o nā huahana āpau, a ʻo ka haʻahaʻa haʻahaʻa dielectric lilo i kūpono no nā noi kiʻekiʻe / broadband kahi e hoʻemi ʻia ai ka hoʻopuehu ʻana a me ka nalowale. Ma muli o kona haʻahaʻa haʻahaʻa haʻahaʻa o ka wai, rtduroid5880 kūpono loa no ka hoʻohana ʻana i ka ʻāina haʻahaʻa kiʻekiʻe.

Hiki ke ʻoki maʻalahi, ʻoki a hana ʻia kēia mau mea kaapuni holomua e hana i kekahi solvent a me ka reagent i hoʻohana mau ʻia i nā papa kaapuni a i ʻole ka lihi a me ka lua electroplating. He haʻahaʻa loa ko lākou nalo uila no nā mea PTFE i hoʻoikaika ʻia, a he haʻahaʻa haʻahaʻa hoʻi lākou a he isotropic. Loaʻa iā lākou nā ʻano uila like ʻole i ka alapine. Hoʻohana ʻia ke alapine kiʻekiʻe rtduroid5880 i nā mokulele kalepa, microstrip a me nā stripline circuits, nā noi ʻōnaehana hawewe millimeter i hoʻohana ʻia i nā radar koa, nā antennas missile, nā hōʻike lekiō kikohoʻe a me nā mea ʻē aʻe. Hoʻolālā ʻia ka rtduroid5880 i hoʻopiha ʻia me ka pūhui PTFE no ka hoʻohana koʻikoʻi o nā kaapuni i hoʻohui ʻia a me nā microcircuits.

Loaʻa iā Rogerpcb ka waiwai DK haʻahaʻa loa o ka laminate keleawe i loaʻa ma ka mākeke. Ma muli o kāna mau dielectric haʻahaʻa o 1.96 ma 10GHz, kākoʻo ʻo rtduroid5880 i nā noi broadband o nā alapine microwave i ka laulā millimeter, kahi e hoʻemi ʻia ai ka hoʻopuehu ʻana a me ka nalowale kaapuni. ʻO ia ka hoʻopiha piha ʻana a me ka māmā PTFE composite me ka haʻahaʻa haʻahaʻa loa (1.37G / cm3) a me ka helu haʻahaʻa o ka hoʻonui wela (CTE) ma ka z-axis. Hiki iā ia ke hāʻawi i nā lua hana kiʻekiʻe-frequency (PTH) a loaʻa i ka uku kiʻekiʻe. Eia kekahi, ʻo ka paʻa o ka dielectric mai ka pā a i ka papa he ʻano like a mau i kahi ākea ākea, a ʻo ka z-axis tcdk ka haʻahaʻa e like me + 22ppm / ° C.
