ʻO ka waiwai CTI (comparative tracking index) he mea koʻikoʻi i ka loiloi ʻana i ka palekana uila o kahi mea. He ana ia i ka hiki o kekahi mea ke pale aku i ka huli uila, he mau ala alakai ia e ulu ana ma ka ili o ka mea ma muli o ka wai, lepo, a me na mea haumia e ae. He mea koʻikoʻi nā waiwai CTI i ke koho ʻana i nā mea no ka uila a me nā noi uila, kahi mea koʻikoʻi ka palekana a me ka hilinaʻi.

ʻO FR4 kahi mea i hoʻopaʻa ʻia i ka lapalapa ahi a me ka wela kiʻekiʻe i hoʻohana nui ʻia i ka hana ʻana i nā papa kaapuni paʻi (PCB) a me nā mea uila ʻē aʻe. Hāʻawi ʻia i kāna hoʻohana nui ʻana i nā noi uila a me ka uila, ʻo ka hoʻomaopopo ʻana i ka waiwai CTI o FR4 he mea nui e hōʻoia i ka palekana a me ka hilinaʻi o ka huahana hope.

No laila, he aha ka waiwai CTI o FR4?

Kuhi ʻia ka waiwai CTI o FR4 ma 175V a ʻoi aku paha. ʻO ia ke ʻano he kūpaʻa kiʻekiʻe ʻo FR4 i ka nānā ʻana, kūpono ia no nā noi kahi e hopohopo ai ka palekana uila. Hoʻokumu ʻia ka waiwai CTI kiʻekiʻe o FR4 i kāna haku mele ʻana, e komo pū ana me ka lole fiberglass a me ka resin epoxy. ʻAʻole hāʻawi kēia haku mele i ka FR4 me nā waiwai insulation uila maikaʻi loa, akā hāʻawi pū kekahi iā ia i ka hiki ke kū i nā wela kiʻekiʻe, e kūpono ia no nā noi e koi ana i ka paʻa wela.

ʻO ka waiwai CTI kiʻekiʻe o FR4 e hōʻoia i hiki iā ia ke pale i ke koʻikoʻi uila kiʻekiʻe me ka ʻole o ka leakage a i ʻole ka haki ʻana, a laila e hoʻonui ai i ka palekana a me ka hilinaʻi o nā huahana uila a me ka uila i hoʻohana ʻia ai. He mea koʻikoʻi kēia i nā noi kahi e kiʻekiʻe ai ka maʻemaʻe a me nā mea haumia, no ka mea, ʻoi aku ka maʻalahi o nā mea me nā koina CTI haʻahaʻa i ka nānā ʻana a me ka hemahema ma lalo o ia mau kūlana.

Ma waho aʻe o nā koina CTI kiʻekiʻe, hāʻawi ʻo FR4 i nā hiʻohiʻona makemake ʻē aʻe e lilo ia i koho mua no nā noi uila. ʻO kēia mau mea e pili ana i ka ikaika mechanical maikaʻi, ke kūpaʻa dimensional a me ke kūpaʻa ʻana i nā kemika a me nā solvents. Hoʻohui ʻia, ʻo FR4 kahi mea kūʻai kumu kūʻai e lilo ia i koho maikaʻi no nā mea hana e ʻimi nei e hana i nā mea uila kiʻekiʻe me ka ʻole o ka hoʻokō ʻana i ka palekana a me ka hana.

I ka hōʻuluʻulu ʻana, ʻo ka waiwai CTI o FR4 he mea koʻikoʻi i ke koho ʻana i nā mea no ka uila a me nā noi uila. ʻO ke kiʻekiʻe o ka waiwai, ʻoi aku ka paʻa o ka mea. Hoʻemi ʻia ka loaʻa ʻana o nā hewa ma muli o ka leakage. ʻO ka waiwai CTI paʻamau no FR4 he 175 a piʻi i ka 600 ma nā mea kūikawā.ʻO Jiujiang Xinxing Insulation Material Co.,ltdʻO ia ka mea hana nui o ka epoxy fiberglass laminated sheet,ka CTI o kā mākou pepa FR4a hiki i 600, he koho maikaʻi loa ia no kāu mea uila a i ʻole nā ​​noi uila.kāhea iā mā˚oue ike hou aku esales1@xx-insulation.com
