He aha ke ʻano o ka ulu ʻana o ka pepa laminate?

2022-09-05

  Ma hope o nā makahiki o ka hoʻomohala ʻana i koʻu ʻāina, ua hoʻomau ka hoʻonui ʻana o nā ʻano o ka laminate sheet e like me FR4 pepa, 3240 pepa epoxy a Pepa Bakelite, a ua hoʻomaikaʻi maikaʻi ʻia ka pae ʻenehana, akā aia nō kahi ākea nui i hoʻohālikelike ʻia me nā ʻāina kūkulu. I mea e hoʻomaikaʻi ai i ka pae ʻenehana o nā papa o nā huahana kaomi a Kina a hoʻonui i ka mākeke hoʻokūkū o nā huahana, pono mākou e hahai i ka mākeke mākeke o nā ʻāpana ʻē aʻe o nā huahana kaomi e like me ke kuhikuhi noiʻi o ka pae aʻe o nā huahana kaomi. ʻO kahi papa o nā huahana kaomi e hoʻololi i nā koi ʻenehana o nā ʻāina i kūkulu ʻia e wehe i ka mākeke honua.


1. Māhele


  Mai ka hiʻohiʻona o ka resin matrix, he nui nā ʻano o Kina, e like me ka resin epoxy, resin phenolic, resin methaclamine, resin diene ether, resin polyaline, a me ka resin silicon. ʻO ka resin polybate. Eia nō naʻe, mai ka manaʻo o ka hoʻonui ʻana i nā mea, aia wale nō nā lole aniani i koʻu ʻāina me ka ʻole o ke aniani. ʻO nā hiʻohiʻona like ʻole o ke kāne o ka papa o ka pā hoʻonui lole aniani e ʻike ʻia, a ʻo ka ikaika mechanical ma ke ala o ka uea aniani he kiʻekiʻe loa, a ʻo ka ikaika mechanical o nā ʻaoʻao ʻē aʻe he ʻilihune, ʻoi aku ka ikaika mechanical o ka vertical ke kuhikuhi o ka lole aniani. E like me ka shear, drilling, attack wire) hiki ke hoʻopaʻa ʻia a me nā mea ʻē aʻe, a ʻo ka pā aniani i manaʻo ʻia e hoʻonā i kēia pilikia. ʻO ka mea i hoʻonui ʻia o ke aniani manaʻo papa o ʻAmelika Hui Pū ʻIa a me Iapana hoʻohana i ka manaʻo lahilahi o 100g/m2 ~ 150g/m2, ʻoiai ʻo ʻEulopa e hoʻohana ana i 300g/m2 ~ 450g/m2 lole pāhaʻi. Aia nā ʻoki pōkole 25mm lōʻihi ma waena o ka lole mānoanoa. wili. ʻOi aku ka ikaika mechanical o ka hope ma mua o 50% kiʻekiʻe ma mua o ka mua.


A me ka Papa 2 Papa 3.


  Eia kekahi, hoʻopuka ʻo Iapana i kahi pā lahilahi mau me nā hiʻohiʻona uila maloʻo, mānoanoa: 0.15mm ~ 0.30mm, a hiki ke hoʻomalu ʻia ka mānoanoa ma loko o ± 5%.


2. Hoʻonohonoho


  I kēia manawa, hoʻohana nā mea hana o nā papa kaomi o Kina i ka hoʻomehana mahu, wehe i ka multi-layer oil compressor, a ʻo ka pilikia nui o nā mea hana ʻo ia ka piʻi nui ʻana o ka mahana, ma luna o ± 10 ° C, ʻaʻole maʻalahi ke kāohi i ka wā o ka ʻO ka paʻi paʻi papa hana, ua pio ka leo kahe, a me ka hana ʻana o ka papa o ka pā kaomi ʻana ʻO ka ʻokoʻa o ka mānoanoa. Hoʻohana nui ka ʻāina i hoʻomohala ʻia i ka mīkini ʻaila hinu wela e hana i nā papa. Ke hoʻohana nei kekahi mau mea hana i nā mīkini puʻupuʻu māmā e hoʻoponopono i kēia mau nīnau.


3. Ka hana o ka pepa laminate


  Pākē aniani fiber -i hoʻonui ʻia ka papa laminate i hoʻonui ʻia e ka lole aniani, a me nā papa kaomi ʻole me ke aniani ʻole. Hoʻohālikelike ʻia kēia hoʻohālikelike me nā huahana like ma ʻEulopa a me ʻAmelika Hui Pū ʻIa. Ke hoʻohālikelike ʻia me nā papa ʻEulopa a me ʻAmelika, mālama ʻia nā papa laminate Kina i nā pilikia ma lalo nei:


  a) Haʻahaʻa ka uila. ʻO ka papa nui i kēia manawa: ʻo ka papa pālahalaha he 30kV, ʻoiai ʻo ka Europa a me ʻAmelika hiki ke piʻi aku ma mua o 45kV. ʻO ke kūpaʻa insulation ma hope o ka hoʻoulu ʻana he 102MΩ ~ 103MΩ wale nō, ʻoiai ʻo ʻEulopa a me ʻAmelika hiki ke hiki i 105MΩ ~ 107MΩ.


  b) He nui ka mānoanoa deviation. No ka pepa laminate me ka mānoanoa o 1mm ~ 3mm, ʻo ka mānoanoa o Kina ka ± 15%~ ± 12%, aʻo ka ʻaoʻao o ka laminate ʻEulopa a me ʻAmelika ʻo ± 10%~ ± 8%.

a) Mea lako


  ʻO ka mīkini gel luna kiʻekiʻe me kahi mea hoʻomehana lōʻihi -infrared me ka catalytic combustion device he waiwai nui i ka manawa hoʻokahi, akā i ka wā lōʻihi, he mea pono. ʻO ka mea mua, hiki i ka mahana o ka mīkini kāpili kiʻekiʻe ke piʻi i 220 ° C, hiki ke hoʻomaluʻia ka mahana ma ka māhele, a me kēlā me kēia neʻe i loko o ± 1 ° C. He kiʻekiʻe ka maikaʻi o ka hanaʻana o ka tape luna a paʻa ka maikaʻi. ʻO ka lua, ua māhele like ʻia ka maʻiʻo o ka lipine o luna. ʻO ke kolu, hiki ke hoʻohana ʻia ka ikehu o ka solvent ma hope o ke puhi ʻana, a hoʻemi ʻia ke kumukūʻai hana. ʻO ka ʻehā, i ka piʻi ʻana o nā koi o ke kaiapuni, ʻo ka hoʻomaʻamaʻa maikaʻi ʻana i ke kinoea ʻōpala ke noi o ka hoʻomohala ʻana i ka nohona, a ʻo ka catalytic combustion kekahi o nā ala hilinaʻi.


  ʻO kā mākou hale hana hou ʻo Jinghong Electronic Technology Co., LTD ua hoʻolako mua i kahi mīkini gel kiʻekiʻe no ka hana ʻana FR4 pepa fiberglass a me na mea he nui o luna o ka pae kiʻekiʻe vacuum kaomi mīkini.


FR4 pepa

3240 pepa epoxy


b) Pepa laminate kiʻekiʻe


  ʻO ka mea mua, e koho i ka lole aniani i mālama ʻia e ka interface ma ke ʻano he mea i hoʻonui ʻia e hoʻonui ai i ka hoʻohālikelike ʻana o ka resin substrate a me ka lole aniani. ʻO ka lua, ʻaʻole pono e hoʻokuʻu ka resin substrate i nā mea molekala haʻahaʻa i ka wā o ke kaʻina hana. ʻO ke kolu, ma lalo o ka manaʻo o ka hōʻoia ʻana i ka liʻiliʻi o ka lipine luna, pono e liʻiliʻi ka volatilization o ka tape luna. ʻO ka hā, hoʻohana ʻia ka papa hana o ka mīkini paʻipaʻi.


c) Halogen -ʻaʻohe lapalapa ahi FR4 pepa


  Me ka hoʻomaikaʻi lohi ʻana o ka mālama ʻana i ke kaiapuni a me nā koi palekana, ua pāpā mālie nā ʻāina kūkulu i ka hoʻohana ʻana i nā mea halogen flame retardant. E aʻo ana i nā mea hana no ka halogen -free flame -retardant structural materials aia i ka piʻi. Aia kēia mau mea i nā mea hana e like me nā mea lawe kaʻa, nā hale, etc.


d) Ke kumu kūʻai haʻahaʻa, ka pepa laminate ikaika kiʻekiʻe


  ʻO ke kumu nui o nā papa paʻi paʻi i ka ʻoihana kūkulu ke kumu kūʻai kiʻekiʻe. Ma keʻano he mea kūkulu hale,ʻaʻole ia e koi wale i ka ikaika kiʻekiʻe, akā he haʻahaʻa haʻahaʻa. No laila, ʻo nā pāpaʻi haʻahaʻa haʻahaʻa a me ka ikaika kiʻekiʻe kekahi o nā kuhikuhi no ka hoʻomohala ʻana.
