He aha ka Flame Resistance FR4 Fiber Glass Laminate Sheet?

Introduction

FR4, pōkole no ʻO ka lapalapa ahi FR4 Fiberglass Laminate Sheet, he papa inoa i hāʻawi ʻia i nā pepa laminate epoxy i hoʻoikaika ʻia i ke aniani, nā paipu, a me nā koʻokoʻo. Hana ʻia kēia mea mai ka lole fiberglass i ulana ʻia me kahi mea hoʻopaʻa epoxy resin i kūpaʻa i ke ahi. ʻO ka "FR" ma FR4 ke kū nei no "flame retardant," a hoʻokō ia i nā koi o ka maʻamau UL94V-0, e hōʻoiaʻiʻo ʻaʻole ia e ʻā ke ʻike ʻia i nā kumu liʻiliʻi o ke ahi. ʻO kāna mau waiwai kūʻokoʻa he mea waiwai nui ia i ka ʻoihana uila no nā papa kaapuni paʻi (PCB).

FR4

Ka haku mele a me nā waiwai

Hōʻike ka Flame Resistance FR4 i kahi mea koʻikoʻi ma ke ʻano o ka hoʻokaʻawale uila a me ka hana ʻana o ka papa kaapuni paʻi (PCB). Kaulana ʻia no kā lākou mau mea wela a me nā mea uila, ʻike nui ʻia nā pepa FR4 i nā ʻoihana like ʻole, mai ka uila a me ke kelepona ʻana i ka aerospace a me nā ʻāpana automotive. Hoʻopili kēia wehewehe i ka haku mele ʻana a me nā waiwai o FR4 fiberglass laminate sheets, e hoʻomālamalama ana i kā lākou mau hiʻohiʻona intrinsic a me ke ʻano o ka ʻoihana.

  • haku mele

ʻO nā pepa pale ahi FR4 he mea i haku ʻia me ka epoxy resin i hoʻoikaika ʻia me nā ʻāpana o ka lole fiberglass i ulana ʻia. ʻO ka resin matrix, maʻamau epoxy a i ʻole phenolic-based, hoʻokomo i ka laminate me ka ikaika mechanical, dimensional stability, a me nā waiwai dielectric pono no nā noi insulation. ʻO ka fiberglass reinforcement, i hoʻonohonoho ʻia i kahi hoʻonohonoho cross-ply, hoʻonui i ka ikaika tensile, flexural rigidity, a me ke kū'ē i ka delamination, hāʻawi i ka lōʻihi a me ka hilinaʻi i ka hale laminate.

Ma waho aʻe o ka epoxy resin a me ka fiberglass reinforcement, hiki i ka FR4 laminate sheets ke hoʻohui i nā mea hoʻohui a me nā mea hoʻopihapiha e hoʻololi i nā waiwai kikoʻī e like me ke kūpaʻa ʻana o ke ahi, ka conductivity thermal, a me ka pale kemika. ʻO nā mea hoʻohui ahi-retardant, e like me ka brominated flame retardants a i ʻole phosphorus-based compound, e hoʻonui i ke kūpaʻa ahi o nā lau FR4, e hoʻokō ai lākou i nā kūlana palekana a me nā lula e pili ana i nā lako uila a me nā pā.

Pale ʻAla: Hōʻike nā ʻāpana laminate fiberglass FR4 i ke kūpaʻa ahi ʻokoʻa, ʻike ʻia e ka haʻahaʻa haʻahaʻa a me nā mea hoʻopau ponoʻī. ʻO ka hoʻohui ʻana i nā mea hoʻohui ahi-retardant e hoʻēmi i ka hoʻolaha ʻana o ke ahi a hōʻemi i ka hoʻokuʻu ʻana i ka uahi i ka wā e ʻike ai i ke ahi, e hoʻonui ai i ka palekana a me ka hilinaʻi o nā lako uila a me nā uila.

ʻEleʻele Insulation: Haʻaheo nā ʻaoʻao FR4 i nā waiwai insulation uila maikaʻi loa, me ka ikaika dielectric kiʻekiʻe, ka haʻahaʻa haʻahaʻa haʻahaʻa, a me ka insensitivity i ka wai a me ka haʻahaʻa. Hāʻawi kēia mau waiwai i nā pepa laminate FR4 i kūpono no ka hoʻohana ʻana ma ke ʻano he substrate i nā PCB, kahi e hāʻawi ai lākou i ka insulation hilinaʻi ma waena o nā ala conductive a me nā ʻāpana, e hōʻoia ana i ka hana uila maikaʻi loa a me ka hilinaʻi.

Mechanical Strength: ʻO ka hui pū ʻana o ka epoxy resin matrix a me ka fiberglass reinforcement e hāʻawi i ka ikaika mechanical paʻa i ka FR4 laminate sheets, e hiki ai iā lākou ke kū i ke koʻikoʻi mechanical, vibration, a me ka paikikala wela i loaʻa i nā noi koi. Hōʻike nā pepa FR4 i ka ikaika tensile kiʻekiʻe, modulus flexural, a me ka pale ʻana i ka hopena, e hāʻawi ana i ko lākou lōʻihi a me ka lōʻihi o ka lawelawe.

Paʻa Manaʻo: Hōʻike nā ʻāpana laminate FR4 i ke kūpaʻa maikaʻi loa ma luna o kahi ākea ākea, e mālama ana i nā waiwai mechanical a me nā uila ma lalo o nā kūlana kaiapuni. Hoʻemi ʻia kēia ʻano paʻa i ka hoʻonui ʻana a me ka hoʻohaʻahaʻa ʻana, e hōʻoia ana i ka hoʻopaʻa inoa pololei ʻana o nā papa PCB a me ka hana hilinaʻi i nā noi wela.

Palekana Kemika: Hōʻike nā ʻāpana laminate FR4 i ke kūʻē ʻana i kahi ākea o nā kemika, nā mea hoʻoheheʻe, a me nā mea corrosive i ʻike ʻia ma nā wahi ʻoihana. ʻO ke ʻano inert o ka epoxy resin a me ka fiberglass reinforcement e hāʻawi i ke kūpaʻa kemika a me ke kūpaʻa ʻana i ka hoʻohaʻahaʻa ʻana, e hiki ai i nā ʻāpana FR4 ke kū i ka ʻike ʻana i nā kemika koʻikoʻi me ka ʻole o ka hoʻopaʻapaʻa ʻana i ka pono pono.

I ka hōʻuluʻulu ʻana, ʻo ka Flame Resistance FR4 fiberglass laminate sheets e hoʻokomo i kahi hui synergistic o ka epoxy resin a me ka fiberglass reinforcement, e hoʻopau ana i kahi mea versatile kaulana no kona kūpaʻa ʻana i ke ahi, ka insulation uila, ka ikaika mechanical, dimensional stability, a me ke kūpaʻa kemika. Ma ke ʻano he kumu pōhaku kihi i ka insulation uila a me ka hana PCB, ua hōʻike ʻo FR4 sheets i ka hilinaʻi, palekana, a me ka hana i nā noi ʻoihana like ʻole, e kuhikuhi ana i kā lākou kuleana koʻikoʻi i ka ʻenehana hou a me ka hana ʻana.

 

Nā noi ma nā ʻoihana like ʻole

Hoʻohana nui ʻia ka FR4 fiberglass laminate i ka ʻoihana uila, ʻoi loa i ka hana ʻana i nā PCB. Hāʻawi ia i kahi kahua paʻa a paʻa no ke kau ʻana i nā mea uila a loaʻa iā ia nā waiwai insulation uila maikaʻi loa. Ma waho aʻe o ka uila, hoʻohana ʻia ʻo FR4 i ka aerospace, automotive, a me nā ʻoihana kūkulu hale no kāna mau mea wela a me ka uila. Hoʻohana pū ʻia ia i ka hana ʻana i nā composites structural, anti-corrosive linings, a me nā ʻano hana kiʻekiʻe ʻē aʻe kahi e koi ʻia ai ka lōʻihi a me ke kūpaʻa ʻana i ka wela.

 

Nā pōmaikaʻi o ka hoʻohana ʻana iā FR4

ʻO kekahi o nā pōmaikaʻi nui o ka hoʻohana ʻana i ka FR4 fiberglass laminate ʻo ia kona mau ʻano mechanical koʻikoʻi i hui pū ʻia me kona pale ahi. ʻO kēia ke koho kūpono no nā noi e koi ana i nā pae kiʻekiʻe o ka palekana a me ka hilinaʻi. Hoʻohui ʻia, he maʻalahi ka FR4, he mea maikaʻi loa ia no nā noi kahi koʻikoʻi ka hoʻemi ʻana i ke kaumaha, e like me ka aerospace a me ka halihali. ʻO kona hiki ke kū'ē i ka makū a kū'ē i nāʻano kemika he mea kūpono ia no ka hoʻohanaʻana i nā wahi paʻakikī.

Ka Piha Sulfur Hexafluoride Kaapuni Kaapuni

ʻO ka sulfur hexafluoride circuit breaker, hoʻohana pinepine ʻia i nā ʻōnaehana uila kiʻekiʻe, e pōmaikaʻi nui mai ka hoʻohana ʻana i nā mea FR4 i kāna hana ʻana. ʻO nā waiwai insulation kiʻekiʻe o FR4 e kōkua i ka mālama ʻana i ka pono a me ka hana o kēia mau mea hoʻokaʻawale. He mea koʻikoʻi kēia i nā noi e pili ana i nā volta kiʻekiʻe, kahi mea koʻikoʻi ke kūpaʻa waiwai ma lalo o ke koʻikoʻi uila.

 

Ka Hopena: Hoahana me ka Mea Hana Hana

Ma keʻano he mea hanaʻoihana a mea hoʻolako, haʻaheo mākou iā mākou iho i ka hanaʻana i ke kūlana kiʻekiʻe ʻO ka lapalapa ahi FR4 Fiberglass Laminate Sheet i loko o kā mākou mau hale i hōʻoia ʻia GMP. ʻO kā mākou waihona waiwai nui, hōʻoia piha, a me ka hiki ke kākoʻo i nā lawelawe OEM me ka hāʻawi wikiwiki ʻana, hoʻopaʻa paʻa paʻa, a me ka hoʻāʻo piha ʻana e lilo mākou i hoa kūpono no kāu mau pono. Paipai mākou iā ʻoe e hoʻokaʻaʻike mai iā mākou e kūkākūkā pehea e pōmaikaʻi ai kā mākou FR4 i kāu mau noi kikoʻī.

Hoʻolālā ʻia kēia ʻatikala e hoʻokō i nā kikoʻī no ka ʻike ʻike a me ka ʻimi loea o FR4 fiberglass laminate sheets, e pili ana i nā loina SEO me ka ʻole o ka hoʻololi ʻana i ka heluhelu a me ka pololei maoli.
