FR4 xaashida Epoxy Glassfiber dahaadhay ee adag
Sharaxaada Alaabta
Alaabtan waxaa lagu dhajiyay heerkulka sare iyo cadaadiska sare leh maro elektaroonik ah oo muraayad ah oo lagu dhejiyay resin epoxy brominated.It oo leh sifooyin farsamo oo sarreeya, guryaha korontada ku shaqeeya iyo guryaha ololka, sidoo kale leh caabbinta kulaylka wanaagsan iyo iska caabinta qoyaanka;
FR-4 waa koodka darajada alaabta ololka u adkeysata, taas oo macneheedu yahay qeexid shay oo ah in shayga xabagta ay tahay in uu iskii u damiyo gubashada ka dib.Magac maaddi ah maaha, balse waa darajo maaddi ah.Magaca FR4 wuxuu ka yimid nidaamka darajooyinka NEMA halkaas oo'FR'u taagan tahay'dabdemiska', waafaqsan heerka UL94V-0.Sidaa darteed, looxyada wareegga guud ee PCB, Waxaa jira noocyo badan oo ah agabka darajada FR-4 ee la isticmaalo, laakiin intooda badan waa walxo isku dhafan oo laga sameeyay Tera-Function epoxy resin oo leh filler iyo fiber galaas ah.
U Hogaansanaanta Heerarka
Iyada oo la raacayo GB/T 1303.4-2009 resin thermosetting koronto laminates adag - Qaybta 4: epoxy resin laminates adag, IEC 60893-3-2-2-2011 walxaha dahaarka qeexitaanka EPGC202.
Astaamaha
1.Qalabka farsamada sare;
2.Guryaha dielectric High;
3.Mechinability wanaagsan
4.Good caabbinta qoyaanka;
5.Cabitaanka kulaylka wanaagsan;
6.Cabsiga heerkulka: Fasalka B
7.Hantida ololka:UL94 V-0
Codsiga
Alaabtan waxaa inta badan loo isticmaalaa sida qaybaha qaab dhismeedka matoorka iyo qalabka korantada, oo ay ku jiraan dhammaan noocyada furaha,qalabka korontada,saxanka xoojinta FPC,filim kaarboon daabacan looxyada wareegga,kombuyuutar qodista,qalabka wax lagu dhalaaliyo (PCB ololka tijaabada)iyo sidoo kale ku habboon deegaanka qoyan hoostiisa iyosaliid transformer.
