Xaashida Dahaaran ee FR4 ee adag ee Epoxy Glassfiber
Sharaxaadda Badeecada
Badeecadan waxaa lagu dahaadhay heerkulka sare iyo cadaadiska sare iyadoo la isticmaalayo maro elektaroonig ah oo fiber galaas ah oo lagu dahaadhay resin epoxy brominated. Waxay leedahay sifooyin farsamo oo sare, sifooyin dielectric ah iyo sifooyin celin olol, waxay sidoo kale leedahay iska caabin kulaylka wanaagsan iyo iska caabin qoyaan;
FR-4 waa kood ka kooban walxo u adkaysta dabka, taasoo la macno ah qeexitaan agab ah oo sheegaya in walaxda resin ay awood u leedahay inay iskeed u damiso ka dib marka la gubo. Ma aha magac walax ah, laakiin waa darajo agab ah. Magaca FR4 wuxuu ka yimid nidaamka qiimeynta NEMA halkaas oo'FR'waxay u taagan tahay'dab-celiye', oo waafaqsan heerka UL94V-0Sidaa darteed, looxyada wareegga guud ee PCB, Waxaa jira noocyo badan oo agab heer FR-4 ah oo la isticmaalo, laakiin intooda badan waa agab isku dhafan oo laga sameeyay Tera-Function epoxy resin oo leh buuxin iyo faybar galaas ah.
U hoggaansanaanta Heerarka
Sida waafaqsan GB/T 1303.4-2009 laminates-ka adag ee warshadaha ee resin thermosetting resin - Qaybta 4: laminates-ka adag ee resin epoxy resin, IEC 60893-3-2-2011 agabka dahaarka - laminates-ka adag ee warshadaha ee resin thermosetting resin - Qaybta 3-2 ee qeexitaanka walxaha shaqsiyeed ee EPGC202.
Astaamaha
