He aha ka FR4 Epoxy Sheet?

ʻO ka lapalapa ahi FR4 Fiber Glass Laminate Sheet he ʻano mea i hoʻohui ʻia i hoʻohana mua ʻia i ka ʻoihana uila no nā papa kaapuni paʻi (PCB) a ma ke ʻano he insulator i nā noi like ʻole. ʻO kāna mau mea nui he fiberglass i ulana ʻia a me kahi mea hoʻopaʻa epoxy resin, e hana ana i ka lapalapa ahi a kūpaʻa loa i ke koʻikoʻi uila a me ka mechanical.

He mea koʻikoʻi nā waiwai pale ahi o kēia mea i nā noi kahi e pono ai ka palekana ahi. ʻO ka kokoke o epoxy ʻAʻole i hoʻomaikaʻi ka tar i kona ʻano mīkini akā kōkua pū kekahi i kona hiki ke kū i nā wela kiʻekiʻe me ka hoʻohaʻahaʻa ʻole a i ʻole ka hoʻouna ʻana i ka pauku luku. Hoʻolilo kēia iā FR4 i koho kūpono no ka hoʻohana ʻana i nā lako mea kūʻai aku, e like me nā tvs a me nā kamepiula, kahi e koi ai nā mana palekana i nā mea e pale ai i ka hoʻolaha ʻana o ke ahi.

Eia kekahi, ʻo ka paʻa paʻa ʻana o FR4 ma lalo o ka pumehana he mea koʻikoʻi i nā noi kikoʻī. ʻO kēia kūpaʻa e hōʻoiaʻiʻo i ka hilinaʻi o nā ana o nā PCB, ʻoiaʻiʻo ma lalo o ka neʻe ʻana o nā kūlana mahana, ʻo ia ke kumu no ka mālama ʻana i ka manaʻo o nā hui uila a me ka nui o ka pono o nā hāmeʻa uila. ʻO kona maʻalahi a me ka maikaʻi ʻole e hoʻomau i ka hana ʻana i ka FR4 i koho maʻamau i waena o nā ʻenekinia a me nā mea hana hale i ka ʻoihana lako.

Ka hoʻomaopopo ʻana i ke ʻano a me nā waiwai o FR4

ʻO ka lapalapa ahi FR4 Fiber Glass Laminate Sheet ua haku ʻia me ka lole fiberglass i ulana ʻia me ka uhi ʻōpala epoxy. Hāʻawi kēia haku mele iā FR4 i kāna mau hiʻohiʻona kumu, e like me ke ʻano mechanical kiʻekiʻe, ka uhi uila nani, a me ke kūpaʻa kemika a me ka wai. Hōʻike ka lole i ka hoʻopaneʻe ahi, me ka helu hoʻopau ʻana o 94V-0, e hōʻike ana i ka pau ʻana o ke ahi i loko o 10 kekona ma kahi hiʻohiʻona kūpaʻa; ʻaʻole hiki ke hoʻā ʻia nā ʻōpala o nā ʻāpana, inā he.

FR4 no ka PCB

Nā hana maʻamau a me nā noi

ʻO ka hoʻohana pono ʻana o FR4 i ka hana ʻana i nā PCB, kahi e hāʻawi ai i ka hoʻokolokolo kōkua a me ka mea hoʻokaʻawale uila ma waena o nā papa keleawe. ʻO nā waiwai mehana nui o FR4 e kūpono i nā kaʻa uila uila kiʻekiʻe a me ka wikiwiki. Ma waho aʻe o ka lakohana, hoʻohana ʻia ʻo FR4 i nā noi kumu like ʻole e koi ana i ke kūpaʻa kiʻekiʻe a me ka paʻakikī.

ʻO nā hāmeʻa i hala a me nā ʻoihana kōkua, ʻike ʻo FR4 i nā noi i ka ʻoihana mokulele ma muli o kona kaumaha māmā a me ke kūpaʻa ʻana i ke ahi, ka wai, a me nā kemika like ʻole. Hoʻohana maikaʻi kēia mau waiwai no ka hoʻohana ʻana i nā papa o loko a me nā ʻāpana o ka mokulele kahi i paʻa ai ka palekana a me ka paʻa. Eia kekahi, hoʻohana ʻia kona mau uhi uhi i loko o ka cockpit a me nā keʻena huakaʻi e pale aku i nā pōʻino uila a me ka mahana.

Eia kekahi, ʻO ka lapalapa ahi FR4 Fiber Glass Laminate Sheet ke hoʻohana ʻia nei ma ka ʻoihana kaʻa. ʻOi aku ka maikaʻi o kona kūpaʻa mahana a me ka maikaʻi kōkua no nā noi ma lalo o ka puʻupuʻu, ka helu ʻana i nā pā uila kaʻa uila i hoʻopaʻa ʻia i nā wahi a me nā papa hana hoʻomalu. ʻO ka maʻalahi o ka mea i nā mahana kiʻekiʻe a me nā kūlana kala ʻole e hoʻololi i ka hoʻonui ʻana i ke ola o nā ʻāpana kaʻa, ʻo ia ka pivotal i ka neʻe ʻana o ka ʻoihana i nā huahana hiki ke mālama ʻia a lōʻihi.

Mea Mechanical a mehana

Hōʻike nā pepa FR4 i nā waiwai mechanical ikaika e like me ka maikaʻi malleable e hoʻonui ana mai 38,000 a 45,000 psi a me ka maikaʻi compressive ma kahi o 65,000 psi. Hiki ke piʻi kona ʻano flexural a hiki i 75,000 psi, e hōʻike ana i kona hiki ke kū a hiki i ke kuhi hewa ʻana ma lalo o ka waihona. Ma ke ʻano wela, hiki iā FR4 ke pale aku i nā mahana hana mau ʻole ma kahi o 130°C (266°F) a i 140°C (284°F), i mea e kūpono ai no nā noi mīkini ʻokoʻa.

Nā Papa Hana Hana

FHe mea koʻikoʻi nā waiwai pale uila o R4 no kona hoʻohana ʻana i nā PCB. Loaʻa iā ia ka maikaʻi dielectric o 20 MV/m, kahi ʻokoʻa e manaʻo ai i nā haki uila i nā kaapuni. ʻO ka dielectric steady o ka mea ma kahi o 4.4, he mea kūpono ia no nā noi uila a me ka uila akā ʻaʻole kūpono paha no nā noi kiʻekiʻe a pololei paha kahi e koi ʻia ai kahi dielectric steady.

ʻO nā pono ma mua o nā mea ʻē aʻe

Hoʻohālikelike ʻia me nā mea ʻē aʻe e like me nā laminates kiʻekiʻe-frequency, ʻO ka lapalapa ahi FR4 Fiber Glass Laminate Sheet ʻoi aku ka maikaʻi o ke kumu kūʻai a lawa no ka laulā o nā noi ʻaʻole makemake i ka loli mau dielectric haʻahaʻa me nā loli wela. Eia nō naʻe, no nā noi e koi ana i ka pololei kiʻekiʻe a me ke kūpaʻa wela, ʻoi aku ka maikaʻi o nā mea i hoʻolālā ʻia no nā noi alapine kiʻekiʻe.

Hāʻawi pū ʻo FR4 i ka ikaika mechanical maikaʻi loa a me ke kūpaʻa ʻana i ka makū, e lilo ia i koho paʻa no nā kūlana kaiapuni he nui kahi e hoʻohaʻahaʻa a hana like ʻole ai nā mea ʻē aʻe. Hoʻonui kēia paʻa i ke ola o nā huahana a hōʻemi i nā kumukūʻai mālama a me ka hoʻololi ʻana, he mea maikaʻi loa ia i nā ʻāpana e like me nā mea uila uila a me nā mīkini ʻenehana.

Ma waho aʻe o kēia mau pōmaikaʻi, ua maʻalahi ka FR4 i ka hana a me ka mīkini, e hiki ai i nā hoʻolālā paʻakikī a me nā pōʻai hana wikiwiki. ʻO kēia maʻalahi o ka hana ʻana he koho maikaʻi ia no nā hoʻomaka a me nā ʻoihana i hoʻokumu ʻia, e hoʻomaʻamaʻa i nā huli wikiwiki i ka hoʻomohala ʻana a me ka hoʻāʻo ʻana. ʻAʻole maʻamau ia ʻano versatility i nā mea kūikawā ʻē aʻe, pono paha e koi aku i nā ʻenehana hana maʻalahi a me nā mea hana.

Kāhea iā mā˚ou

Ma ke ʻano he mea hoʻolako ʻoihana ʻoihana, haʻaheo mākou iā mākou iho i ka hāʻawi ʻana i ka mea kiʻekiʻe ʻO ka lapalapa ahi FR4 Fiber Glass Laminate Sheet me nā lawelawe piha. ʻO kā mākou hale hana i hōʻoiaʻiʻoʻia e GMP e mālama i kahi waihona waiwai nui, e hōʻoia ana i ka hoʻouna wikiwikiʻana i nā kauoha nui a me nā kauoha maʻamau. Kākoʻo mākou i nā noi OEM, hāʻawi i ka ʻeke paʻa a paʻa, a hele mai nā huahana āpau me nā palapala hōʻoia piha. Hoʻolālā ʻia kā mākou kākoʻo ʻenehana a me nā lawelawe hoʻāʻo e hoʻokō i nā pono o nā mea kūʻai honua e ʻimi nei i ka pilina hilinaʻi a lōʻihi.
