He aha nā waiwai o Flame Resistance FR4 Fiber Glass Laminate Sheets?

Introduction

  ʻO ka pale ahi FR4 fiberglass laminate pepa he mea koʻikoʻi i nā ʻoihana like ʻole, kahi palekana, hilinaʻi, a me ka lōʻihi ka mea nui. ʻO kēia mau pepa, i haku ʻia me ka fiberglass reinforcement i hoʻokomo ʻia i loko o kahi epoxy resin matrix, hāʻawi i kahi hui kūʻokoʻa o nā waiwai e pono ai lākou no nā noi e koi ana i ka pale ahi ikaika a me ka insulation kiʻekiʻe.

  Ma kēia ʻatikala, ʻimi mākou i nā waiwai o FR4 fiberglass laminate sheets, e ʻimi ana i kā lākou haku mele, ikaika mechanical, insulation uila, kūpaʻa wela, kūpaʻa kemika, a me nā ʻano pale ahi. Ma ka hoʻomaopopo ʻana i kēia mau waiwai, hiki i nā ʻenekinia a me nā mea hoʻolālā ke hoʻoholo i ka ʻike e pili ana i ke koho ʻana i nā mea, e hōʻoia ana i ka hana maikaʻi loa a me ka palekana o kā lākou huahana a me nā ʻōnaehana.

  I loko o kēia ʻimi ʻana, e nānā mākou i nā waiwai koʻikoʻi o FR4 fiberglass laminate sheets, e hoʻomālamalama i ko lākou koʻikoʻi i nā ʻoihana like ʻole a me nā noi. Mai nā papa kaapuni uila a hiki i nā ʻāpana aerospace, he hana koʻikoʻi kēia mau pepa i ka hōʻoia ʻana i ka pono a me ka hilinaʻi o nā ʻōnaehana koʻikoʻi. E noʻonoʻo kākou i nā waiwai e hoʻolilo i ka FR4 fiberglass laminate sheets i koho maikaʻi no nā noi koi.

FR4 pepa epoxy

Na Pono Mekani a me Kino

  • ʻO ka ikaika tensile: FR4 fiberglass laminate sheets loaʻa ka ikaika tensile kiʻekiʻe, e ʻae iā lākou e pale i nā ikaika huki nui me ka ʻole o ka deformation a i ʻole ka hemahema. Mālama kēia waiwai i ka paʻa o nā ʻāpana i hoʻopaʻa ʻia i ka ʻāʻī, e like me nā kākoʻo a me nā mea lawe ukana.
  • ʻO ka ikaika flexural: ʻO ka ikaika flexural o FR4 fiberglass laminate sheets e hoʻoholo i ko lākou hiki ke pale aku i ke kuʻi ʻana a i ʻole ka wili ʻana me ka haki ʻole. Pono kēia waiwai no nā ʻāpana i hoʻopaʻa ʻia i nā ukana wili, e like me nā papa kaapuni, kahi mea koʻikoʻi ke kūpaʻa dimensional no ka hana hilinaʻi.
  • Ka ikaika compressive: FR4 fiberglass laminate sheets hōʻike i ka ikaika compressive maikaʻi loa, e hiki ai iā lākou ke pale aku i nā ikaika compressive me ka ʻole o ka hāʻule ʻana a i ʻole deformation. He mea nui kēia waiwai no nā ʻāpana i hoʻopili ʻia, e like me nā pale insulating i loko o nā kaiapuni kiʻekiʻe.
  • ʻO ka pale ʻana i ka hopena: ʻO ka pale ʻana o ka FR4 fiberglass laminate sheets e hōʻoia i ko lākou hiki ke kū i nā hopena hikiwawe a i ʻole nā ​​haʻalulu haʻalulu me ka ʻole o ka haki ʻana a i ʻole delaminating. He mea koʻikoʻi kēia waiwai no nā ʻāpana i ʻike ʻia i nā hopena mechanical i ka wā o ka lawelawe ʻana, ka lawe ʻana, a i ʻole ka hana.
  • ʻO ka paʻakikī: FR4 fiberglass laminate sheets e hōʻike maʻamau i ka paʻakikī kiʻekiʻe, e hāʻawi ana i ke kū'ē i ka indentation o ka ʻili a i ʻole ka ʻoki ʻana. Hoʻonui kēia waiwai i ko lākou kūpaʻa a me ke kū'ē i kaʻaʻahu, e hāʻawi ana i kā lākou hana lōʻihi i nā wahi koi.
  • Density: FR4 fiberglass laminate sheets he haʻahaʻa haʻahaʻa a kiʻekiʻe, ma muli o kā lākou haku mele ʻana a me ka mānoanoa. Hoʻopili kēia waiwai i ko lākou kaumaha a me nā hiʻohiʻona holoʻokoʻa holoʻokoʻa, e pili ana i nā mea e like me ka hiki ke amo a me ka buoyancy.
  • Hoʻonui Thermal: Hōʻike nā ʻāpana laminate fiberglass FR4 i nā coefficient hoʻonui wela haʻahaʻa, ʻo ia hoʻi, hoʻonui liʻiliʻi lākou ke ʻike ʻia i nā ʻano like ʻole. Mālama kēia waiwai i ka paʻa o ka dimensional a pale i ka warping a i ʻole distortion o nā ʻāpana ma muli o ke kaʻa kaʻa wela.
  • ʻO ka hoʻoheheʻe ʻana o ka wai: FR4 fiberglass laminate sheets e hōʻike ana i ka haʻahaʻa haʻahaʻa o ka hoʻoheheʻe ʻana i ka wai, e pale ai i ka pehu ʻana a i ʻole nā ​​hoʻololi ʻana i nā ʻano o nā wahi haʻahaʻa. Hōʻoia kēia waiwai i ko lākou kūpaʻa a me ka hilinaʻi i nā noi ʻana i ka moisture.
  • Palekana Kemika: Hāʻawi ka FR4 fiberglass laminate sheets i ke kūpaʻa maikaʻi loa i kahi ākea o nā kemika, nā mea hoʻoheheʻe, a me nā mea ʻino. Mālama kēia waiwai i ko lākou paʻa a me ka lōʻihi o ke ola ʻana i nā wahi kemika paʻakikī, kahi e hopohopo ai ka ʻike ʻana i nā mea corrosive.
  • ʻO ka pale ahi: E like me kā lākou inoa e hōʻike ai, FR4 fiberglass laminate pepa ʻAi ʻia i ka lapalapa ahi, e hōʻike ana i ka haʻahaʻa haʻahaʻa a me nā waiwai hoʻopau iā ia iho. Mālama kēia waiwai i ko lākou hoʻokō ʻana i nā kānāwai palekana ahi koʻikoʻi a hoʻonui i ka palekana o nā mea i loko o nā wahi ahi.

  I ka hōʻuluʻuluʻana, ka mechanical a me ke kino waiwai o ʻO ka pale ahi FR4 fiberglass laminate pepa he kuleana koʻikoʻi i ka hoʻoholo ʻana i ko lākou kūpono no nā noi like ʻole. Mai ka tensile kiʻekiʻe a me ka ikaika flexural a hiki i ka hopena maikaʻi loa a me ka lapalapa ahi, hana kēia mau waiwai i nā pepa FR4 i koho kūpono no nā mea koʻikoʻi e koi ana i ka hilinaʻi, ka lōʻihi, a me ka palekana i nā wahi koi.

 

Nā Pono Wela

  Kūlana ʻo FR4 no kona hiki ke hoʻopaʻa i kona kūpaʻa i nā mahana kiʻekiʻe, kahi hiʻohiʻona koʻikoʻi no nā mea i hoʻohana ʻia i nā wahi wela wela e like me nā keʻena ʻenekini a i ʻole ka umu ʻoihana. ʻO kāna conductivity thermal, ʻoiai ʻaʻole kiʻekiʻe loa, ua lawa ia e hoʻomaʻamaʻa i ka hoʻoheheʻe ʻana o ka wela i nā noi uila, hoʻonui i ka palekana a me ka hana (Wikipedia) (Curbell Plastics).

 

Na Waiwai Uila

  ʻO kekahi o nā hiʻohiʻona hiʻohiʻona o FR4 ʻo kāna mau mana insulation uila kiʻekiʻe. Loaʻa iā ia ka ikaika dielectric kiʻekiʻe, kahi e pale ai i ka leakage uila a hōʻoia i ka pono o nā kaʻa uila. ʻO ka haʻahaʻa dielectric mau a me ka dissipation factor o FR4 e kūpono ia no nā noi uila kiʻekiʻe, kahi mea koʻikoʻi ka hōʻemi ʻana i ka nalowale o ka hōʻailona (Wikipedia) (FR4 Material).

 

ʻO ka hoʻopaneʻe ʻana o ke ahi a me ka pale ʻana i nā kemika

  ʻO ka "FR" ma FR4 ke kū nei no "Flame Retardant," e hōʻike ana i kona hiki ke pale aku i ka puhi ahi a lohi i ka laha ʻana o ke ahi. Hoʻolilo kēia iā FR4 i mea waiwai maikaʻi loa no nā noi i mea nui ka palekana ahi. Hoʻohui ʻia, kūpaʻa nā lau FR4 i nā ʻano kemika a me nā mea hoʻoheheʻe, e hoʻomaikaʻi ana i kā lākou pono i nā wahi paʻakikī (Atlas Fibre) (Jaco Products, Inc.).

 

Hoʻohana like ʻole a me nā noi

  ʻIke ʻia ka maʻalahi o FR4 i kāna ʻano nui o nā noi. Hoʻohana nui ʻia ia i ka hana ʻana i nā papa kaapuni paʻi (PCB) no nā mea uila like ʻole, mai nā mea uila uila a i nā ʻāpana aerospace. Ma waho aʻe o nā mea uila, hoʻohana ʻia ʻo FR4 i nā ʻāpana hana, nā mea insulating, a me nā ʻāpana ʻoihana kiʻekiʻe a me nā ʻāpana aerospace ma muli o kona ikaika a paʻa (FR4 Material) (Jaco Products, Inc.).

FR4

Panina

  I ka hopena, he mea nui ka FR4 fiber glass laminate sheets i ka ʻenekinia hou ma muli o ko lākou ikaika mechanical, thermal stability, electrical insulation properties, and flame retardancy. ʻO ko lākou hiki ke hana ma lalo o nā kūlana koʻikoʻi e lilo lākou i koho koho ma waena o nā ʻoihana like ʻole.

  Ma ke ʻano he mea hana ʻoihana a me ka mea hoʻolako me nā hale i hōʻoia ʻia e GMP, loaʻa ka waiwai nui, nā palapala hōʻoia piha, a me ke kākoʻo no OEM, hoʻopuka wikiwiki, hoʻopaʻa paʻa paʻa, a me nā hiki ke hoʻāʻo, kono mākou iā ʻoe e hoʻokaʻaʻike mai iā mākou no kāu pono waiwai FR4. Aia ko mākou ʻike a me nā kumuwaiwai iā ʻoe no ka hoʻomohala ʻana i nā hopena kiʻekiʻe a hilinaʻi i kūpono i kāu mau koi.

 

Kāhea iā mā˚ou

  No ka ninau e pili ana ʻO ka pale ahi FR4 fiberglass laminate pepa a me nā mea ʻē aʻe, mai hoʻokaʻulua e kelepona mai iā mākou ma info@jhd-material.com. Ma keʻano he mea hoʻolako hanaʻoihana me kahi hale hana i hōʻoiaʻiʻoʻia e GMP, nā waihona waiwai nui, a me nā palapala hōʻoia piha, ua kūpaʻa mākou e hālāwai i kāu mau pono. E pōmaikaʻi mai kā mākou kākoʻo OEM, ka lawe wikiwiki ʻana, ka hoʻopaʻa ʻana i ka ʻike, a me ke kākoʻo hoʻāʻo e hōʻoia i ka maikaʻi a me ka hilinaʻi o kāu mau papahana. E hui pū me mākou e kiʻi i nā mea waiwai kiʻekiʻe a hui pū i nā papahana kūʻai honua. E kelepona mai iā mākou i kēia lā e kūkākūkā i kāu mau koi a e ʻimi pehea e hiki ai iā mākou ke kākoʻo i kāu mau hana.
