ke hoʻololi i papa kaapuni i paʻi ʻia (PCB) kahi hana maʻamau no ka nui o nā ʻenekini uila (EE). ʻOiai nā makahiki o ka hoʻolālā hoʻolālā PCB, ʻaʻole maʻalahi ka hoʻokumu ʻana i nā hoʻolālā PCB hana kiʻekiʻe kiʻekiʻe. Nui a hewahewa nā kumu e noʻonoʻo ai, a ʻo nā mea papa kekahi o lākou. ʻO nā mea hana i hoʻohana ʻia e hana PCBS he mea nui. Ma mua o ka hana ʻana, pono e noʻonoʻo pono i nā waiwai o nā mea i nā ʻano like ʻole, e like me ka maʻalahi, ke kūpale ʻana o ka mahana, ka hoʻomau ʻana o ka dielectric, ka ikaika dielectric, ka ikaika, ka hoʻopili a pēlā aku. ʻO ka hana a me ka hoʻopili ʻana o kahi papa kaapuni e pili pono i nā mea i hoʻohana ʻia. ʻImi hou kēia ʻatikala i nā mea PCB. No laila e nānā no ka ʻike hou aku.

He aha nā ʻano mea i hoʻohana ʻia i ka hana ʻana PCB?

He papa inoa kēia o nā mea nui i hoʻohana ʻia e hana i nā papa kaapuni. E nānā kāua.

Fr-4: Pōkole ʻo FR no FIRE RETARDENT. ʻO ia ka mea PCB i hoʻohana mau ʻia no nā ʻano hana PCB a pau. Hana ʻia ka fiberglass epoxy laminate FR-4 me ka hoʻohana ʻana i ka lole fiberglass i ulana ʻia me ka mea hoʻopaʻa resin retinant. Kaulana kēia mea no ka mea hāʻawi ia i ka uila uila maikaʻi a maikaʻi ka ikaika mechanical. Hāʻawi kēia mea i ka ikaika nui loa. ʻIke ʻia ia no kāna hana maikaʻi a me ka lawe ʻana i ka wai.

Fr-5: Hana ʻia ka substrate i kahi mea aniani i hoʻoikaika ʻia a me kahi mea hoʻopaʻa epoxy resin. This is a good choice for multi-layer circuit board design. Hana maikaʻi ia i ka hoʻoheheʻe ʻana i ke kēpau a maikaʻi a me nā pono ʻenehana maikaʻi loa i nā mahana wela. Hoʻomaopopo ʻia no ka lawe haʻahaʻa ʻana o ka wai, kūpaʻa kemika, nā pono uila maikaʻi a me ka ikaika nui.

Fr-1 a me FR-2: Hoʻokomo ʻia ia i ka pepa a me nā hui phenolic a maikaʻi no nā hoʻolālā papa kaapuni hoʻokahi. He mau waiwai like ko nā mea ʻelua, akā ʻo FR2 kahi aniani hoʻololi hoʻololi aniani ma mua o FR1.

Cem-1: Pili kēia mea i ka hui o nā mea epoxy hui (CEM). ʻO ka hoʻonohonoho he epoxy synthetic resin, fiberglass lole a me nā kumu non-fiberglass. Hoʻohana ʻia nā mea i hoʻohana ʻia i nā papa kaapuni ʻaoʻao hoʻokahi, he kumukūʻai a me ka pale ahi. Kaulana ia no ka hana mechanical a me ka uila maikaʻi loa.

Cem-3: E like me CEM-1, ʻo kēia kekahi mea epoxy hui. He mau pale retardant kona a hoʻohana ʻia no nā papa kaapuni ʻelua ʻaoʻao. ʻOi aku ka ikaika o ka mīkini ma mua o FR4, akā ʻoi aku ka maikaʻi ma mua o FR4. Therefore, it is a good alternative to FR4.

Keleawe: ʻo ke keleawe ke koho mua i ka hana ʻana i hoʻokahi a me nā papa kaapuni multilayer. ʻO kēia no ka mea hāʻawi ia i nā kiʻekiʻe ikaika, kiʻekiʻe conductivity uila a me ka uila conductivity a me ka haʻahaʻa kemika reactivity.

Tg kiʻekiʻe: Hōʻike ka Tg kiʻekiʻe i ka mahana wela o ke aniani kiʻekiʻe. Kūpono kēia mea PCB no nā papa i ke noi noi. Tg nā mea i ke ana wela kiʻekiʻe a me ka lōʻihi lōʻihi delamination paʻa paʻa.

Rogers: Kuhi pinepine ʻia ʻo RF, ʻike ʻia kēia mea no ka hoʻohālikelike me nā laminate FR4. Ma muli o kāna conductivity terminal kiʻekiʻe a me ka impedance kaohi, hiki ke maʻalahi i nā papa kaapuni kēpau.

Aluminium: Ke pale nei kēia mea PCB malleable a malleable i nā papa keleawe mai ka wela ʻana. Ua koho nui ʻia no kona hiki ke hoʻopau koke i ka wela.

ʻO alumini manuahi Halogen: Kūpono kēia metala no nā polokalamu launa i ke kaiapuni. Ua hoʻomaikaʻi ke alumini manuahi Halogen i ka hoʻomau o ka dielectric a me ka diffusivity o ka wai.

I loko o nā makahiki, ua loaʻa ka mahalo nui ʻia o PCBS a loaʻa i ka laulā o nā noi i nā ʻoihana e pono ai nā kaapuni paʻakikī. No laila, koho nui i ka pono PCB mea nui, no ka mea pili i ka hana a me nā ʻano wale nō, akā i ke kumukūʻai holoʻokoʻa o ka papa. Koho i nā kumuhana e pili ana i nā koi noi, nā hanana kaiapuni, a me nā palena ʻē aʻe i kū i mua o ka PCB.
