FR4 Olimba Epoxy Glassfiber Laminated Sheet
Mafotokozedwe Akatundu
Chogulitsachi chinapangidwa ndi kutentha kwambiri komanso kuthamanga kwambiri ndi nsalu yamagetsi yagalasi yodzazidwa ndi epoxy resin yokhala ndi brominated. Chili ndi mphamvu zambiri zamakanika, mphamvu za dielectric komanso mphamvu zoletsa moto, komanso chimakhala ndi mphamvu zabwino zoteteza kutentha komanso chinyezi;
FR-4 ndi code ya mtundu wa zinthu zosagwira moto, zomwe zikutanthauza mfundo ya zinthu zomwe utomoni uyenera kuzimitsa wokha ukayaka. Si dzina la zinthu, koma mtundu wa zinthu. Dzina lakuti FR4 limachokera ku dongosolo la NEMA lowerengera komwe'FR'imayimira'choletsa moto', mogwirizana ndi muyezo wa UL94V-0Chifukwa chake, ma PCB circuit board ambiri, Pali mitundu yambiri ya zipangizo za FR-4 zomwe zimagwiritsidwa ntchito, koma zambiri mwa izo ndi zinthu zopangidwa ndi Tera-Function epoxy resin yokhala ndi filler ndi ulusi wagalasi.
Kutsatira Miyezo
Mogwirizana ndi GB/T 1303.4-2009, ma laminates olimba a mafakitale a thermosetting resin - Gawo 4: ma laminates olimba a epoxy resin, IEC 60893-3-2-2011, zotetezera - ma laminates olimba a mafakitale a thermosetting resin - Gawo 3-2 la mfundo za EPGC202 payokha.
Mawonekedwe
1. Katundu wapamwamba wamakina;
2. Katundu wapamwamba wa dielectric;
3. Kuthekera Kwabwino kwa Makina
4. Kukana chinyezi kwabwino;
5. Kukana kutentha kwabwino;
6. Kukana kutentha: Giredi B
7. Katundu woletsa moto: UL94 V-0
Kugwiritsa ntchito
Izi zimagwiritsidwa ntchito makamaka ngati zida zomangira magalimoto ndi zida zamagetsi, kuphatikizapo mitundu yonse ya switch、zida zamagetsi、FPC yolimbitsa mbale、bolodi lozungulira losindikizidwa ndi filimu ya kaboni、chobowolera makompyuta、zida zoyeretsera nkhungu ndi zosungunulira (lawi loyesera la PCB）komanso yoyenera pamalo onyowa komansomafuta a transformer.
