Rau Karāhe Epoxy Fr4 Rau G10 Rau laminate kāore i hipokina me te Āhuatanga Ārai Mīhini me te Hiko Pai
Whakaahuatanga Hua
I pania tēnei hua ki te kakahu muka karāhe hiko kua whakakikoruatia ki te kapia epoxy brominated mā te pāmahana teitei me te pēhanga teitei. He teitei ōna āhuatanga miihini, he pai hoki tōna ātete wera me te makuku.
Ko te FR-4 he waehere mō te taumata o ngā rauemi ātete-mura, arā, he whakatakotoranga rauemi e kī ana me taea e te rauemi kapia te tineia i a ia anō i muri i te tahunga. Ehara i te ingoa rauemi, engari he taumata rauemi. Ko te ingoa FR4 i ahu mai i te pūnaha whakatauranga NEMA i reira te'FR'e tohu ana mō'ārai ahi', e tutuki ana i te paerewa UL94V-0Nō reira, he maha ngā momo rauemi FR-4 e whakamahia ana mō ngā papa hiko PCB whānui, engari ko te nuinga he rauemi hiato i hangaia ki te kapia epoxy Tera-Function me te whakakī me te muka karāhe.
Te Whakatutuki i ngā Paerewa
E ai ki te GB/T 1303.4-2009 kapia whakamaroke hiko ahumahi - Wāhanga 4: kapia epoxy kapia whakamaroke, IEC 60893-3-2-2011 rauemi ārai - kapia whakamaroke hiko ahumahi kapia whakamaroke - Wāhanga 3-2 o te whakatakotoranga rauemi takitahi EPGC202.
Ngā Āhuatanga
1. Ngā āhuatanga miihini teitei;
2. Ngā āhuatanga hiko-whakakore teitei;
3. He pai te Mīhini
4. Ātete pai ki te makuku;
5. He ātete wera pai;
6. Ātete pāmahana: Tau B
7. Āhuatanga ātete mura: UL94 V-0
Tono
Ko te nuinga o tēnei hua e whakamahia ana hei wāhanga hanganga mō te motuka me ngā taputapu hiko, tae atu ki ngā momo pana katoa.、taputapu hiko、Pereti whakapakari FPC、papa ara iahiko tānga kiriata waro、papa keri rorohiko、taputapu pokepokea ai me te whakarewa (mura whakamātautau PCB）ā, he pai hoki i raro i te taiao mākū,hinu whakawhiti.
