ʻO ka CTI kiʻekiʻe (Comparative Tracking Index) o FR4 epoxy fiberglass board he mea koʻikoʻi ia e kūpono ai i nā noi kahi e koi ʻia ai ka insulation uila kiʻekiʻe.ʻO ka helu CTI kiʻekiʻe e hōʻoia i ka mea hiki ke kū i nā volta kiʻekiʻe me ka pilikia ʻole o ka haki ʻana a i ʻole ka nānā ʻana.Hana kēia waiwai i ka papa fiberglass epoxy CTI FR4 kiʻekiʻe i koho maikaʻi loa no ka hoʻohana ʻana i nā mea uila, e like me nā mea hoʻololi, switchgear, a me nā panela mana.

Ma waho aʻe o kāna mau waiwai insulation uila maikaʻi loa, hāʻawi pū ka papa kiʻekiʻe CTI FR4 epoxy fiberglass i ke kūpaʻa wela kiʻekiʻe.He kūpono kēia no nā noi kahi e ʻike ʻia ai ka mea i nā wela kiʻekiʻe.No ka laʻana, hoʻohana maʻamau ia i ka hana ʻana i nā papa kaapuni paʻi (PCB) no nā mea uila, kahi e hoʻokau ʻia ai ka papa i ka soldering a me nā kaʻina hana wela kiʻekiʻe.

ʻO ka ikaika mechanical o ka papa fiberglass epoxy CTI FR4 kiʻekiʻe kekahi hiʻohiʻona nui e hoʻolilo iā ia i mea makemake i nā noi like ʻole.ʻO kona kūlana kūlana maikaʻi loa a me ke kū'ēʻana i ka hopena a me ka abrasion e kūpono ia no ka hoʻohanaʻana i nā noi kahi e pono ai ka ikaika mechanical.No ka laʻana, hoʻohana maʻamau ia i ke kūkulu ʻana i nā ʻāpana mīkini, nā ʻāpana hana, a me nā kākoʻo insulating.

ʻO ka versatility o ke kiʻekiʻe CTI FR4 epoxy fiberglass board i kūpono no ka nui o nā noi i ka ʻoihana automotive, aerospace, a me nā ʻoihana moana.ʻO kona kūpaʻa ʻana i nā kemika, ka makū, a me ka radiation UV e lilo ia i mea hilinaʻi no ka hoʻohana ʻana i nā wahi paʻakikī.Hiki ke hoʻohana ʻia i ka hana ʻana i nā ʻāpana no nā kaʻa, nā mokulele, a me nā moku moana, kahi mea koʻikoʻi ka lōʻihi a me ka hana.

I ka hōʻuluʻulu ʻana, ʻo ka papa fiberglass epoxy CTI FR4 kiʻekiʻe he mea maʻalahi me ka insulation uila maikaʻi loa, ke kūpaʻa wela, a me ka ikaika mechanical.Hiki i kona mau waiwai ke kūpono no ka nui o nā noi i nā ʻoihana like ʻole.Inā hoʻohana ʻia i nā lako uila, hana PCB, hana mīkini, a i ʻole nā ​​​​mea kaʻa a me ka aerospace, kiʻekiʻe CTI FR4 epoxy fiberglass papa e hōʻoiaʻiʻo ʻia he mea hilinaʻi a kūpono hoʻi e hoʻokō i nā koi koi o nā noi ʻoihana hou.ʻO kāna helu CTI kiʻekiʻe, i hui pū ʻia me kāna mau mea wela a me ka mīkini, e hōʻoia i hiki iā ia ke hana maikaʻi i nā kaiapuni paʻakikī, e lilo ia i koho i makemake ʻia no nā ʻenekinia a me nā mea hoʻolālā i nā ʻano ʻano like ʻole.

ʻO ka FR4 i hana ʻia eʻO Jiujiang Xinxing Insulation material Co.LtdʻO CTI600, ʻo ka FR4 maʻamau mai ka mākeke ʻo CTI200-400, no laila inā ʻo kāu noi i nā wahi paʻakikī, koho iā mākou he koho maikaʻi.
