Waht bụ SMD LED BT Substrate:

SMD LED BT Substrate na-ezo aka na PCB nke arụpụtara na ihe BT ma tinye ya na ngwaahịa SMD LED.Dịiche dị na PCB nkịtị , a na-etinye BT ihe na MD LED BT Substrate, nke bụ ngwaahịa Mistubishi Gas Chemical Co., Inc. Ihe BT nke B (Bismaleimide) na T (Triazine) resin nwere uru nke TG dị elu (255 ~ 330 ° C), nguzogide okpomọkụ (160 ~ 230 Celsius C), mgbochi mmiri, obere dielectric mgbe niile (DK) na obere mgbasa ihe (Df). SMD Ikanam bụ ọhụrụ elu ugwu semiconductor ìhè-emitting ngwaọrụ, na obere achụsasị n'akuku bụ nnukwu, ìhè ịdị n'otu, elu pụrụ ịdabere, ìhè na agba tinyere na-acha ọcha na agba, ọ na ọtụtụ-eji na a dịgasị iche iche nke electronic ngwaahịa.
