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

Introduction:

Paʻa ahi FR4 Pepa Epoxys hoʻohana nui ʻia i nā ʻoihana like ʻole ma muli o ko lākou ʻano kūʻokoʻa o ka mahana. He mea koʻikoʻi ka hoʻomaopopo ʻana i ka pale wela o FR4 no ka hōʻoia ʻana i ka palekana a me ka hilinaʻi o nā mea uila, nā papa kaapuni paʻi (PCB), a me nā noi ʻē aʻe kahi e hoʻohana ʻia ai kēia mau mea. Ma kēia ʻatikala, ʻimi mākou i nā kikoʻī o ka pale wela FR4, e ʻimi ana i kona hiki a me nā noi.

1. Ka hoomaopopo ana i ka FR4 Fiber Glass Laminate:

ʻO FR4, i kapa ʻia ʻo Fire Retardant 4, kahi loiloi o ka uhi epoxy i hoʻoikaika ʻia i ka fiberglass. He ʻano lole i haku ʻia me ka lole fiberglass i ulana ʻia me ka epoxy gum, ʻo ia ka mea i hoʻōla ʻia ma lalo o ka mahana a me ke kaumaha. Kaulana ʻo FR4 no kāna mau waiwai hoʻokaʻawale uila, ka maikaʻi mechanical, a me ke kūpaʻa ʻana i ka mahana a me ke ahi, e lilo ia i koho kaulana i ka ʻoihana lako.

2. Kū'ē wela o FR4:

ʻO ka pale wela o FR4 kekahi o kāna mau hiʻohiʻona kaulana loa. FR4 Pepa Epoxys ua hoʻolālā ʻia e kū i nā wela kiʻekiʻe me ka ʻole o ka hoʻokō ʻana i kā lākou keenness kumu a i ʻole ka hoʻokō uila. Hiki ke loli ka pale wela kūpono o FR4 ma muli o nā ʻāpana e like me ka wehewehe kikoʻī o ka epoxy gum a me ka mānoanoa o ka uhi. E like me ka mea maʻamau, hiki i ka FR4 ke pale i nā mahana hana hoʻomaha ʻole mai 130°C a i 180°C.

3. Nā ʻāpana e hoʻoikaika ana i ka pale wela:

Hoʻololi kekahi mau mea hoʻololi i ka pale wela o FR4 Pepa Epoxys. Hoʻopili kēia mau mea i ka maikaʻi o nā mea momona i hoʻohana ʻia i ka hana ʻana, ka mānoanoa o ka uhi, ka kokoke o nā mea i hoʻohui ʻia no ka hoʻopaneʻe ahi, a me ka lāʻau lapaʻau ma waena o ka hanauna. ʻO nā mea waiwai FR4 kiʻekiʻe me nā mea kāpī maikaʻi a me ka hoʻolaha fiberglass ʻaʻahu e hōʻike i ka pale ʻana o ka wela ma mua o nā koho haʻahaʻa haʻahaʻa.

ʻO kahi kiʻi ʻē aʻe e pili ana i ka pale wela o nā uhi uhi FR4 ʻo ia ke ʻano o ka gum i hoʻohana ʻia i kā lākou hanauna. ʻO nā pā epoxy, ka mea i hoʻohana maʻamau ʻia i nā uhi FR4, loaʻa ke kūpaʻa mehana nui a hiki ke kū i nā wela kiʻekiʻe me ka ʻole o ka pala. I kēlā me kēia hihia, ʻo ka kikoʻī kikoʻī o ka epoxy tar a me kona aniani neʻe wela (Tg) e hoʻoholo i ke kū a me ka nui o ka wela o ka lole FR4. Hōʻike ka Tg kiʻekiʻe i ke kūpaʻa mahana ʻoi aku ka maikaʻi, e ʻae ana i ka FR4 e mālama i kāna mau waiwai i nā wela kiʻekiʻe.

Eia kekahi, ʻo ka hoʻomākaukau hoʻomākaukau ʻana o ka uhi FR4 ma waena o ka hana ʻana he mea koʻikoʻi i kona pale ʻana i ka wela. ʻO ka hoʻomaʻamaʻa ʻoluʻolu e hōʻoiaʻiʻo i ka paʻa ʻana o ke kā a hoʻohālikelike i kahi paʻa paʻa me ka fiberglass, e hana ana i kahi paʻa paʻa e hiki ke kū i nā pilikia mehana. Hiki i ka ho'ōla kūpono ʻole a hōʻino ʻole paha ke alakaʻi i nā microvoids a i ʻole nā ​​wahi palupalu i loko o ka uhi, e hōʻemi ana i kona hiki ke kū i nā wela kiʻekiʻe me ka ʻole o ka distortion a me ka delamination.

Ma ka outline, ka mahana kū'ē o FR4 Pepa Epoxys Hoʻopili ʻia e kekahi mau ʻāpana, e helu ana i ka maikaʻi o nā mea waiwai, ka mānoanoa o ka uhi, nā mea i hoʻohui ʻia i ka lapalapa ahi, ke ʻano o ka tar a me nā kikoʻī, a me ka hoʻomākaukau ʻana. ʻO ka hoʻonui ʻana i kēia mau ʻāpana i waena o ka hanauna he mea nui ia no ka hoʻokō ʻana i nā mea FR4 me ka paʻa wela kiʻekiʻe a me ka maikaʻi paʻa ʻole i nā noi e koi ana i ka hoʻolauna ʻana i nā wela kiʻekiʻe.

4. Nā noi o FR4 i nā kūlana wela kiʻekiʻe:

Ma muli o kāna mau waiwai pale wela, ʻike ʻo FR4 i nā noi like ʻole i nā kūlana wela kiʻekiʻe ma luna o nā ʻoihana like ʻole. ʻO kekahi noi koʻikoʻi i ka hana ʻana i nā pepa kaapuni paʻi (PCB) no nā hāmeʻa uila e hana ana i nā kūlana noi. Hiki i nā FR4 PCB ke kū i nā mahana wela i ʻike ʻia ma waena o nā palapala patching me ka ʻole o ka delamination a i ʻole ka pōʻino o ka hana uila.

ʻO kekahi noi ʻana o FR4 i nā kūlana wela kiʻekiʻe aia i ka ʻoihana kaʻa, kahi e wehe ʻia ai nā mea uila i nā wela kupaianaha ma waena o nā ʻano hana e like me ka hoʻopaʻa ʻana a me nā kūlana hana ma lalo o ka pā. ʻO ka hiki o FR4 ke hoʻomau i kāna mau waiwai mīkini a me ka uila i nā wela kiʻekiʻe e kūpono ia no ka hoʻohana ʻana i nā ʻāpana hoʻokele kaʻa, nā mea ʻike, a me nā ʻōnaehana uila ʻē aʻe e pono e hana hilinaʻi i nā kūlana wela.

Eia kekahi, hoʻohana ʻia ka uhi aniani fiber FR4 i nā lako mīkini a me nā mea hana e hoʻohua ai i ka mahana a i ʻole i hoʻokomo ʻia i nā pae wela kiʻekiʻe. No ka hihia, hiki ke loaʻa iā FR4 i ka hana o nā papa hoʻomehana, nā ʻāpana kapuahi, a me nā mea hana ʻē aʻe e pono ai ke kani pumehana a me ka paʻakikī. ʻO kāna mau waiwai pale ahi e hoʻolilo iā ia i lole i makemake nui ʻia no nā noi e pili ana i nā lapalapa hāmama a i ʻole nā ​​pōʻino ahi paha, e hāʻawi ana i kahi papa o ka palekana.

Ma ka rundown, hoʻoikaika nā waiwai pale wela o FR4 i kona hoʻohana ʻana i ka holo ākea o nā noi wela kiʻekiʻe ma luna o nā ʻoihana like ʻole. Mai nā pepa kaapuni i paʻi ʻia a me nā lako kaʻa a hiki i nā lako mīkini a me nā mea hana, hāʻawi ʻo FR4 i ke kani pumehana koʻikoʻi a me ka paʻakikī e kū i ka noi ʻana i nā kūlana kūlohelohe me ka ʻole o ka hoʻokō ʻana a me ka palekana.

5. Panina:

I ka hopena, FR4 Fiber Glass Laminate Pepa hāʻawi i nā waiwai kūʻokoʻa i ka wela, e hoʻolilo iā lākou i mea koʻikoʻi i nā noi kahi maʻamau ka hōʻike ʻana i nā mahana kiʻekiʻe. ʻO ka hoʻomaopopo ʻana i nā palena wela a me nā hiʻohiʻona hoʻokō o FR4 he kumu no ka hōʻoia ʻana i ka maikaʻi ʻole a me ka palekana o nā hāmeʻa uila a me nā mea ʻē aʻe e hoʻohana ana i kēia mau mea.

Kāhea iā mā˚ou: No ka hana 'oihana o ʻO ka lapalapa ahi FR4 Fiber Glass Laminate Sheet, hoʻokaʻaʻike mai iā mākou i kēia lā. He hale hana GMP mākou me kahi waihona waiwai nui a me nā palapala hōʻoia piha e hoʻokō i kāu mau koi. Kākoʻo mākou i nā kauoha OEM a hāʻawi i ka lawe wikiwiki ʻana me ka paʻa paʻa. E kelepona iā mākou ma info@jhd-material.com e kūkākūkā i kāu mau pono a e ʻimi pehea e hiki ai iā mākou ke hana pū.
