Hiki i ka Flame Resistance FR4 Fiber Glass Laminate Sheet ke pale i ke ahi?

ʻO ka lapalapa ahi FR4 Fiber Glass Laminate Sheet Kaulana ʻo ia no kona kūpaʻa ʻana i ka lapalapa ahi, e lilo ia i mea i makemake ʻia i nā noi like ʻole kahi mea nui o ka palekana ahi. Ma ʻaneʻi, e ʻimi mākou i ka hiki o FR4 i ke kū ʻana i ke ahi, i kākoʻo ʻia e nā ʻike i kona haku mele ʻana, nā waiwai, a me nā hoʻohana maʻamau.

 

Ka hoʻomaopopo ʻana i ka FR4 Material Composition

ʻO FR4, kahi mea i hoʻohana nui ʻia i ka uila a me ka ʻenekini uila, loaʻa kona inoa mai "Flame Retardant 4." Hōʻike kēia inoa i kāna mau waiwai pale ahi a me kona hoʻokō ʻana i nā kūlana kikoʻī. ʻO ka hoʻomaopopo ʻana i kāna haku mele e hoʻomālamalama i kāna mau waiwai a me nā hoʻohana:

Ka lole Fiberglass: FR4 ka mea nui i haku ʻia me ka lole fiberglass i ulana ʻia. ʻO Fiberglass kahi mea māmā, lōʻihi, a maʻalahi i hana ʻia mai nā pulu aniani maikaʻi. ʻO ka lole fiberglass ka mea hoʻoikaika ma FR4. Hāʻawi ia i ka ikaika mechanical, rigidity, a me ke kūpaʻa dimensional i ka mea.

Epoxy Resin Binder:The fiberglass cloth in FR4 is impregnated with an epoxy resin binder. ʻO kaʻahu resins are thermosetting polymers known for their excellent adhesion, chemical resistance, and mechanical properties. The epoxy resin matrix holds the fiberglass cloth together, providing cohesion and stability to the composite material.

Nā Pākuʻi Hoʻopaʻa ahi: Hoʻokomo nā mea FR4 i nā mea hoʻohui ahi e hoʻonui i ko lākou pale ahi. Hiki i kēia mau mea hoʻohui ke hoʻokomo i nā pūhui brominated, pūhui phosphorous, a i ʻole nā ​​​​mea kemika ʻē aʻe e pale ai i ka laha ʻana o ke ahi a hoʻemi i ka hana ʻana o ka uahi. Hiki i nā mea hoʻohui ahi ke kōkua iā FR4 e hoʻokō i nā kūlana palekana a me nā hoʻoponopono, kūpono ia no ka hoʻohana ʻana i nā noi kahi e hopohopo ai ke ahi.

Nā mea hoʻohui ʻē aʻe: Ma muli o nā hoʻohālikelike kikoʻī a me nā makemake o ka mea hana, hiki i ka FR4 ke loaʻa i nā mea hoʻohui hou e hoʻololi i kāna mau waiwai. Hiki i kēia mau mea hoʻohui ke hoʻokomo i nā mea hoʻopihapiha no ka hoʻoikaika ʻana, nā antioxidants no ka paʻa, a i ʻole nā ​​​​mea puaʻa no ka waihoʻoluʻu. Hiki i ke koho a me ka noʻonoʻo o nā mea hoʻohui ke hoʻololi i nā ʻano like ʻole o FR4, e like me ka ikaika mechanical, thermal stability, a me nā waiwai uila.

Hana ʻia: FR4 hana ʻia ma ka waiho ʻana i nā ʻāpana he nui o ka lole fiberglass i hoʻopiha ʻia me ka epoxy resin a laila hoʻokau iā lākou i ka wela a me ke kaomi e hoʻōla i ka resin a hoʻopaʻa pū i nā papa. ikaika, kūpaʻa wela, a me ka pale ʻana i ke ahi.

noi

ʻO ka lapalapa ahi FR4 Fiber Glass Laminate Sheet hoʻohana nui ʻia i nā papa kaapuni paʻi (PCB), kahi e lawelawe ai ma ke ʻano he substrate no ka kau ʻana i nā ʻāpana uila a hāʻawi i nā pili uila.

Hoʻohana ʻia ia i nā ʻāpana insulation uila, nā ʻāpana hoʻolālā, nā mea insulating thermal, a me nā noi ʻē aʻe kahi e pono ai ka hui pū ʻana o ka ikaika, insulation, a me ka pale ahi.

ʻO ka hoʻomaopopo ʻana i ka haku mele ʻana o FR4 e hāʻawi i ka ʻike i kāna mau waiwai a me ka versatility, e lilo ia i koho kaulana i nā ʻoihana like ʻole mai ka hana uila a hiki i ka ʻenehana aerospace.

Nā noi ma waho aʻe o ka pale ahi: Ma muli o kāna mau waiwai paʻa, hoʻohana nui ʻia ʻo FR4 i ka hana ʻana o ka papa kaapuni paʻi (PCB), kahi e hana ai ma ke ʻano he insulator a me ke kākoʻo kūkulu. ʻO kāna mau waiwai insulation uila maikaʻi loa a me ka lōʻihi mechanical e kūpono ai ia no ka aerospace, automotive, a me nā mea hana ʻoihana (FR4 Material) (Jaco Products, Inc.).

 

ʻO nā waiwai pale ahi

Pono nā waiwai pale ahi o FR4 no ka hōʻoia ʻana i ka palekana i nā noi like ʻole, ʻoi loa i ka uila a me ka ʻenekini uila kahi e hiki ai i nā pōʻino ahi ke hoʻopilikia nui. Eia kahi hiʻohiʻona o nā waiwai pale ahi o FR4:

Nā Pākuʻi Hoʻopaʻa Pahu: Hoʻokumu ʻia nā mea FR4 me nā mea hoʻohui ahi e hōʻemi i ko lākou flammability a pale i ka laha ʻana o ke ahi. Hiki i kēia mau mea hoʻohui ke hoʻokomo i nā pūhui halogenated (e laʻa, brominated flame retardants), phosphorous compound, a i ʻole nā ​​mea kemika ʻē aʻe e hoʻopau i ke kaʻina puhi ahi. ʻO ka hoʻohui ʻia ʻana o nā mea hoʻohui ahi e hoʻonui i ka hiki o FR4 ke kū i ka ʻike ʻana i ke ahi a hōʻemi i ka hiki ke ʻā.

Hoʻemi ʻia ka Flammability: Hōʻike nā mea FR4 i ka hōʻemi nui ʻana i ka flammability i hoʻohālikelike ʻia me nā mea ʻē aʻe ʻaʻole-flame-retardant. Ke hoʻokau ʻia i kahi kumu lapalapa, kūʻē pinepine ʻo FR4 i ka ʻā a me ka puhi ʻana, e kaupalena ana i ka laha ʻana o ke ahi a hōʻemi i ka hopena o ka pōʻino waiwai a i ʻole ka ʻeha.

Hoʻokumu ʻia ka uahi haʻahaʻa: Ma kahi o ka pale ʻana i nā lapalapa, ua hoʻolālā ʻia nā hana FR4 e hōʻemi i ka hana ʻana o ka uahi i ka wā o ka puhi ʻana. He mea koʻikoʻi ka hoʻoulu ʻana o ka uahi haʻahaʻa no ka mālama ʻana i ka ʻike a me ka hoʻomaʻamaʻa ʻana i ka hoʻokuʻu ʻana i ka palekana i ka wā o ke ahi.

Hoʻokō me nā Kūlana: Hana ʻia nā mea FR4 e hoʻokō i nā kūlana kūʻē ahi a me nā lula i hoʻokumu ʻia e nā hui ʻoihana a me nā keʻena aupuni. ʻO ka hoʻokō ʻana i nā kūlana e hōʻoia i ka hoʻokō ʻana o nā huahana FR4 i nā koi palekana i kuhikuhi ʻia a me nā pae hoʻokō, e hāʻawi ana i ka hōʻoiaʻiʻo o kā lākou mau waiwai pale ahi.

Hoʻohana ʻia i loko o nā Kaiapuni Kūleʻa ahi: Ma muli o ko lākou mau ʻano pale ahi, hoʻohana maʻamau ʻia nā mea FR4 i nā noi i mea nui ka palekana o ke ahi, e like me nā pā uila, switchgear, control panels, and printed circuit boards (PCBs). ʻO ka hoʻohana ʻana iā FR4 e kōkua i ka hoʻēmi ʻana i ka pilikia o ka hoʻolaha ʻana o ke ahi a hoʻonui i ka palekana holoʻokoʻa o nā ʻōnaehana uila a me nā uila.

ʻOiai ke hāʻawi nei nā mea FR4 i nā waiwai kūʻē i ka lapalapa ahi, pono e noʻonoʻo i nā mea ʻē aʻe e like me ka mānoanoa waiwai, nā kūlana kūlohelohe, a me ka loaʻa ʻana o nā mea puhi ahi hou ma kahi kokoke. ʻO ka hoʻāʻo maʻamau a me ka mālama ʻana i nā alakaʻi palekana e pono e hōʻoia i ka hoʻomau ʻana o ka FR4 i nā wahi ahi.

 

Hana wela a me ka mīkini

Hiki iā FR4 ke pale i nā mahana a hiki i ka 140 ° C, a hiki i kāna mau aniani hoʻololi kiʻekiʻe ke kiʻekiʻe mai 115 ° C a hiki i 200 ° C ma muli o ke ʻano kikoʻī a me ka hana hana i hoʻohana ʻia.

ʻO kona kūpaʻa wela he mea kūpono ia no nā kaiapuni kahi i hana ʻia ai ka wela, e like me nā noi uila (Wikipedia)​​ (pcbknow | Nā mea a pau PCB !)​.

 

Hoʻohālikelike i ka FR4 me nā mea ʻē aʻe

Hoʻohālikelike pinepine ʻia ʻo FR4 me G10, kekahi ʻano o ka epoxy laminate. ʻOiai kaʻana like ʻo G10 i nā waiwai mechanical a insulating o FR4, ʻaʻole ia i nā mea hoʻohui ahi e hiki ai i ka FR4 ke kūpono i nā wahi ahi.

No laila,ʻO ka lapalapa ahi FR4 Fiber Glass Laminate Sheet ʻōlelo ʻia ma kahi e pono ai ka hoʻoikaika ʻana i ke ahi (Current Inc) (Jaco Products, Inc.).

 

Ka Hopena: Pono a me ka lako ʻoihana

ʻO ka hiki o FR4 ke pale aku i ke ahi, i hui pū ʻia me kona kūpaʻa mechanical a me ka wela, he koho hilinaʻi ia no ka nui o nā noi.

Ke ʻimi nei ʻoe i hoa hana hana ʻoihana? Mai nana hou aku! He mea hoʻolako hilinaʻi mākou me kahi hale hana i hōʻoia ʻia e GMP, nā waihona waiwai nui, a me nā palapala hōʻoia piha. Loaʻa kā mākou lawelawe i ke kākoʻo OEM, ka hoʻopuka wikiwiki ʻana, ka hoʻopili pono ʻana, a me ke kākoʻo hoʻāʻo.

E hui pū kākou e hoʻokō i kāu mau papahana! E kelepona iā mākou ma info@jhd-material.com.
