Pepa Laminated Fiberglass Epoxy FR4
Nā Kuhikuhi Huahana
Ua laminated ʻia kēia huahana e ka mahana kiʻekiʻe a me ke kaomi kiʻekiʻe me ka lole glassfiber uila i hoʻopaʻa ʻia me ka resin epoxy brominated. Me nā waiwai mechanical kiʻekiʻe, nā waiwai dielectric a me nā waiwai flame retardant, me ke kūpaʻa wela maikaʻi a me ke kūpaʻa makū;
ʻO FR-4 kahi code o kahi papa o nā mea pale ahi, ʻo ia hoʻi kahi kikoʻī mea e pono ai kahi mea resin ke kinai iā ia iho ma hope o ke kuni ʻana. ʻAʻole ia he inoa mea, akā he papa mea. Loaʻa ka inoa FR4 mai ka ʻōnaehana māka NEMA kahi e kū ai ka 'FR' no 'fire retardant', e kūlike ana me ke kūlana UL94V-0.
Hoʻokō me nā kūlana
E like me GB/T 1303.4-2009 nā laminates paʻakikī ʻoihana thermoset uila - Māhele 4: nā laminates paʻakikī epoxy resin, IEC 60893-3-2-2011 nā mea hoʻokaʻawale - nā laminates paʻakikī ʻoihana thermoset uila - Māhele 3-2 o ka kikoʻī mea pākahi EPGC202.
Noi
Hoʻohana nui ʻia kēia huahana ma ke ʻano he ʻāpana kūkulu no nā lako motika a me nā lako uila, me nā ʻano kuapo āpau, nā lako uila, ka pā hoʻoikaika FPC, nā papa kaapuni paʻi kiʻiʻoniʻoni kalapona, ka papa wili kamepiula, nā lako hoʻoheheʻe a me nā lako hoʻoheheʻe (lapalapa hoʻāʻo PCB); a kūpono hoʻi ma lalo o ke kaiapuni pulu a me ka ʻaila hoʻololi.

Nā nīnau i nīnau pinepine ʻia
Q1: Ke kālepa nei ʻoe i kahi hui a mea hana paha?
ʻO mākou ka mea hana alakaʻi o ka composite insulating uila, ua hana mākou i ka mea hana thermoset rigid composite mai ka makahiki 2003. ʻO kā mākou hiki ke 6000TONS / makahiki.
Q2: Nā Laʻana
Ua noa nā laʻana, pono ʻoe e uku no ka uku hoʻouna.
Q3: Pehea ʻoe e hōʻoiaʻiʻo ai i ka maikaʻi o ka hana nui?
No ke ʻano, ka nui a me ka mānoanoa: e hana mākou i ka nānā piha ma mua o ka hoʻopili ʻana.
No ka maikaʻi o ka hana: Hoʻohana mākou i kahi ʻano paʻa, a e nānā mau ʻia ka laʻana, hiki iā mākou ke hāʻawi i ka hōʻike nānā huahana ma mua o ka hoʻouna ʻana.
Q4: Ka manawa hāʻawi
Aia nō ia i ka nui o ke kauoha. Ma ke ʻano laulā, ʻo ka manawa hāʻawi he 15-20 mau lā.
Q5: Pūʻolo
E hoʻohana mākou i ka pepa hana lima ʻoihana e hoʻopili ai ma ka pallet plywood. Inā loaʻa iā ʻoe nā koi pūʻolo kūikawā, e hoʻopili mākou e like me kāu pono.
Q6: Uku
TT, 30% T/T ma mua, kaulike ma mua o ka hoʻouna ʻana. Ke ʻae nei mākou iā L/C.
