    Sharaxaadda alaabta

    Badeecadani waxaa lagu dahaaray heerkulka sare iyo cadaadiska sare oo leh maro elektaroonig ah oo muraayad ah oo lagu dhajiyay brominated epoxy resin.It oo leh aalado farsamo sare leh, guryaha dielectric iyo sifooyinka ololka, sidoo kale leh iska caabin kuleyl wanaagsan iyo u adkeysiga qoyaanka;

    FR-4 waa sumad heer ah oo ah alaab ololka u adkaysata, taas oo macnaheedu yahay qeexitaan maadadeed oo ah in maadada miraha ay awood u leedahay inay iskeed u bakhtiijiso ka dib gubashada. Ma aha magac maadi ah, laakiin waa darajo maaddo ah. Magaca FR4 wuxuu ka yimid nidaamka qiimeynta NEMA halkaasoo ahFRu taagan yahay dab damiska, u hoggaansan heerka UL94V-0. Sidaa darteed, guddiyada guud ee wareegga PCB, Waxaa jira noocyo badan oo ah qalabka darajada FR-4 ee la isticmaalo, laakiin badankood waa qalab isku dhafan oo laga sameeyey cusbada Tera-Function epoxy oo leh faylalka iyo fijarka dhalada.

    U hogaansanaanta Heerarka

    Iyadoo la raacayo GB / T 1303.4-2009 koronto warshad kuleyliyaha warshadaha laminates adag - Qaybta 4: laminates adag epoxy, IEC 60893-3-2-2011 qalabka dahaarka - qalabka korontada ku shaqeeya ee heerkulbeegga korontada - Qaybta 3-2 ee maaddada shaqsiga faahfaahinta EPGC202.
