FR4 Rigid Epoxy Glassfiber Laminated Mapepala
Mafotokozedwe Akatundu
Izi zinali laminated ndi kutentha kwapamwamba ndi kuthamanga kwakukulu ndi nsalu ya glassfiber yamagetsi yopangidwa ndi brominated epoxy resin.It yokhala ndi makina apamwamba kwambiri, katundu wa dielectric ndi katundu wolepheretsa moto, komanso amakhala ndi kutentha kwabwino komanso kukana chinyezi;
FR-4 ndi kachidindo ka giredi la zinthu zolimbana ndi malawi, zomwe zikutanthauza kuti zinthu zomwe utomoni uyenera kuzimitsa yokha ukayaka.Si dzina lakuthupi, koma kalasi yakuthupi.Dzina FR4 limachokera ku NEMA grading system pomwe ma'FR'imayimira'chozimitsa moto', mogwirizana ndi muyezo wa UL94V-0.Choncho, matabwa ambiri PCB dera, Pali mitundu yambiri ya zipangizo FR-4 kalasi ntchito, koma ambiri a iwo ndi gulu zipangizo zopangidwa Tera-Function epoxy utomoni ndi filler ndi galasi CHIKWANGWANI.
Kutsatira Miyezo
TS EN 60893-3-2-2009 / TS EN 60893-3-2-2011 zida zotsekera zotchinga zamagetsi thermosetting resin mafakitale hard laminates - Gawo 4: Epoxy resin hard laminates Zithunzi za EPGC202.
Mawonekedwe
1.High makina katundu;
2.High dielectric katundu;
3.Good Mechinability
4.Good chinyezi kukana;
5.Good kutentha kukana;
6.Kukana kutentha: Gulu B
7.Katundu wamoto: UL94 V-0
Kugwiritsa ntchito
Izi zimagwiritsidwa ntchito makamaka ngati zida zamagalimoto ndi zida zamagetsi, kuphatikiza mitundu yonse yosinthira,zida zamagetsi,FPC yowonjezera mbale,matabwa ozungulira a carbon film,pobowola pakompyuta,nkhungu ndi zida zosungunulira (PCB test lawi）;komanso oyenerera pansi pa kunyowa chilengedwe ndimafuta a transformer.
