Hiki i ka Flame Resistance FR4 Fiber Glass Laminate Sheet ke hoʻohana ʻia no nā papa kaapuni paʻi (PCB)?

ʻO ka hoʻomaopopo ʻana iā FR4 Fiber Glass Laminate Sheets

FR4, i ʻike ʻia ʻo FR4 Pepa Epoxy, he ʻano ʻōnaehana epoxy resin i hoʻohui ʻia me ka hoʻoikaika ʻana i ka lole aniani i ulana ʻia. Hoʻokumu kēia hui ʻana i kahi pepa laminate ikaika no nā noi uila like ʻole, me nā papa kaapuni paʻi (PCB). FR4 pepa ua hoʻolālā ʻia e kū i nā wela kiʻekiʻe a hāʻawi i nā waiwai insulation uila maikaʻi loa, e hana ana iā lākou i koho kaulana i ka ʻoihana uila.

Na waiwai o ʻO ka lapalapa ahi FR4 Fiber Glass Laminate Sheets ua hana maʻamau no nā noi uila. ʻO kā lākou kiʻekiʻe dielectric kiʻekiʻe e hōʻoiaʻiʻo e hiki ke pale pono ʻia nā lau ma waena o nā mea conductive, e kali ana i nā kahe uila a i ʻole nā ​​​​kaapuni pōkole. He mea koʻikoʻi kēia i nā pepa kaapuni paʻakikī kahi i hoʻokaʻawale ʻia nā ala conductive. Ua noʻonoʻo maikaʻi ʻia ka conductivity mahana o FR4 e nānā i ka hoʻopuʻi ʻana i ka pumehana i loko o nā hāmeʻa uila, e pale aku i ka wela a me ka pōʻino.

Eia kekahi, na ano kino o FR4 pepa hāʻawi i kā lākou pono i ka hana ʻana i nā palapala. ʻAʻole maʻalahi lākou, mālama i ko lākou ʻano a me nā ana ma lalo o ka holo o nā kūlana kūlohelohe, e hoʻomāmā i ka hana a me ka hōʻiliʻili ʻana i nā ʻāpana uila. ʻOiai ʻo ko lākou hiki ʻole, hiki ke ʻoki pololei ʻia nā ʻāpana FR4 a komo i ke koi ʻana i nā ʻano ʻāpana like ʻole a me nā hoʻolālā āpau e pono ai no nā hoʻolālā kaapuni.

ʻO ka hoʻomaopopo ʻana i nā waiwai a me nā hiʻohiʻona o FR4 Fiber Glass Cover Sheets he kumu no ke koho ʻana i ka lole substrate kūpono no ka hana ʻana i ka papa kaapuni paʻi. Ma ka hoʻonui ʻana i kā lākou hui kūikawā o ka mea hoʻokaʻawale uila, ka hoʻokele mahana, a me ka paʻakikī o ke kino, hiki i nā mea hana ke hana i nā pepa kaapuni e hoʻokō i nā koi koi o nā mea uila kiʻekiʻe.

FR4 Pepa

ʻO ka ʻāpana o FR4 ma PCB Manufacturing

Ma ke kahua o ka hana ʻana o PCB, hoʻokani ʻo FR4 i kahi ʻāpana koʻikoʻi e like me ka lole substrate. Hoʻokumu ka substrate i ka hoʻokumu ʻana o ka PCB, e hāʻawi ana i ka mechanical back a me ka uhi ma waena o nā conductive. Hoʻohana nui ʻia ka uhi uhi FR4 ma muli o ko lākou kiʻekiʻe kiʻekiʻe, ke kūpaʻa ʻana o ka dimensional, a me nā waiwai pale ahi, he mea nui ia no ka hōʻoia ʻana i ka maikaʻi ʻole a me ka palekana o nā hāmeʻa uila.

Ma waho aʻe o kēia, ʻo nā waiwai uhi uila kupaianaha o FR4 i kūpono no ka pale ʻana i nā kaʻa pōkole a me nā ahi uila, e hōʻoiaʻiʻo ana i ka hana paʻa o nā hāmeʻa uila. ʻO kona hiki ke kū i ka volta kiʻekiʻe a pale aku i ka uila mai ke kahe ʻana ma waena o nā mea conductive he mea nui ia no nā pepa kaapuni a me nā noi uila ʻē aʻe. Hoʻololi kēia waiwai palekana i ka hoʻomau ʻana i ke akamai o ka hoʻolālā kaapuni a pale aku i nā pōʻino hiki ke hoʻokumu ʻia e ka ukana nui a i ʻole nā ​​​​pii.

ʻO ka hoʻohana ʻana o FR4 i ka hana ʻana i ka PCB e kōkua pū i ka paʻakikī a me ke ola o nā hāmeʻa uila. ʻO kona kūpaʻa ʻana i ka mahana, nā kemika, a me ka maʻemaʻe e hōʻoiaʻiʻo e hiki i ka PCB ke hana hilinaʻi maoli i nā kūlana kala ʻole a noi ʻole. He mea kūpono kēia iā FR4 no ka holo ākea o nā noi, mai nā hāmeʻa kūʻai maʻamau a hiki i ke kumu kumu a me nā lako mīkini.

I ka wehewehe ʻana, ʻaʻole hiki ke hoʻonui ʻia ka ʻāpana o FR4 i ka PCB fabricating. Hāʻawi ia i ke kua mechanical koʻikoʻi, ka mea hoʻokaʻawale, a me ka hōʻoiaʻiʻo e kūʻē i nā ʻāpana kūlohelohe like ʻole, e lilo ia i lole kumu no ka hōʻoiaʻiʻo ʻana i ka maikaʻi ʻole, palekana, a me ka hoʻokō ʻana i nā hāmeʻa uila. Ma ka hoʻohana ʻana i kēia mau waiwai, hiki i nā mea hana ke hana i nā PCB ikaika a hoʻomau e hoʻokō i nā noi hoʻonui o nā hāmeʻa holomua.


Nā pōmaikaʻi o ka hoʻohana ʻana iā FR4 no nā PCB

Aia kekahi mau kiko kikoʻī i ka hoʻohana ʻana iā FR4 no nā noi PCB. ʻO ka mea mua, hāʻawi ʻo FR4 i ka hoʻokō mehana maikaʻi, hoʻolaha maikaʻi i ka hana mehana ma waena o ka hana, ma kēia ala e hoʻomaikaʻi ai i ka maikaʻi ʻole o nā mea uila. Eia kekahi, loaʻa iā FR4 nā waiwai dielectric nui, e hōʻemi ana i ka pōʻino o ka hae a me ke kamaʻilio ʻana ma waena o kēia mau mea, he mea nui ia no nā noi kiʻekiʻe.

Eia kekahi, hiki koke ke kiʻi ʻia ʻo FR4 a me ke kumu kūʻai i hoʻohālikelike ʻia i nā mea elective, e lilo ia i mea hoʻonaninani no nā mea hana e ʻimi nei e hoʻopaʻa i nā kumukūʻai hanauna me ka ʻole o ka hoʻohālikelike ʻana i ka maikaʻi. Ma waho aʻe, ua hui pū ʻo FR4 me nā ʻano hana PCB maʻamau, e ʻae ana i ka hoʻohui maʻalahi i nā kahe hana hana.

Nā mea e noʻonoʻo ai i ke koho ʻana iā FR4 no nā noi PCB

Ke koho ʻana iā FR4 no nā noi PCB, pono e noʻonoʻo ʻia kekahi mau mea e hōʻoiaʻiʻo ai i ka hoʻokō kūpono a me ka maikaʻi ʻole. ʻO ka mea mua, pono e nānā pono ʻia ka loiloi o FR4 e pili ana i nā pono kūikawā o ka noi. Hiki ke hāʻawi aku nā mea kiʻekiʻe kiʻekiʻe FR4 i nā hiʻohiʻona hoʻokō i hoʻomaikaʻi ʻia, akā ma ke kumu kūʻai kiʻekiʻe.

Hoʻohui ʻia, pono ke koho ʻia ka mānoanoa a me ke kaumaha keleawe o ka uhi FR4 e pili ana i ka pono mechanical a me nā pono uila o ka PCB. Hāʻawi nā uhi mānoanoa i hoʻonui ʻia ka maikaʻi mechanical a me ka hoʻopuʻi mahana ʻoi aku ka maikaʻi, ʻoiai nā mea kaupaona keleawe kiʻekiʻe e hoʻoikaika i ka hiki ke lawe i kēia manawa.

Eia kekahi, pono e noʻonoʻo ʻia nā ʻāpana kūlohelohe e like me ka mahana a me ka mugginess, no ka mea hiki ke hoʻopilikia i ke kani lōʻihi a me ka maikaʻi ʻole o ka PCB. He mea maʻamau ke koho ʻana i nā mea FR4 i hiki ke kū i nā kūlana hana o ka noi noi e hōʻoia i ka hoʻokō kūpono a me ke ola.


Ka hopena: Leveraging FR4 no ka maikaʻi PCB hana

I ka hopena,ʻO ka lapalapa ahi FR4 Fiber Glass Laminate Sheets He koho maikaʻi loa ia no nā noi papa kaapuni paʻi (PCB) ma muli o kā lākou hana wela, nā waiwai dielectric, a me ka maikaʻi. Ma ke koho pono ʻana i ka māka kūpono, mānoanoa, a me ke kaumaha keleawe o ka mea FR4, hiki i nā mea hana ke hōʻoia i ka hana kūpono a me ka hilinaʻi o kā lākou mau mea uila.

Ma ke ʻano he mea hoʻolako hana ʻoihana loea i ka FR4 laminate sheets, hāʻawi mākou i kahi ākea o nā huahana kiʻekiʻe i hoʻohālikelike ʻia e hoʻokō i nā pono like ʻole o kā mākou mea kūʻai. Me kā mākou hale hana GMP, waiwai nui, a me nā palapala hōʻoia piha, ua kūpaʻa mākou i ka hāʻawi ʻana i nā huahana a me nā lawelawe ʻoi aku e kākoʻo i nā koi OEM a hoʻomaʻamaʻa i ka lawe wikiwiki ʻana. E kelepona iā mākou ma info@jhd-material.com e aʻo hou aʻe e pili ana pehea e hiki ai iā mākou ke kōkua iā ʻoe e hoʻomaikaʻi i kāu kaʻina hana PCB a huki i nā mea kūʻai honua e hui pū me mākou.
