Ukwethulwa kwezinto ze-FR4

I-FR ku-FR4 imele i-flame retardant, futhi inombolo yesi-4 ihlukanisa izinto ezibonakalayo kwezinye izinto zalesi sigaba.I-FR4 iyi-fiber yengilazi eqiniswe i-epoxy laminate ebukeka njengeshidi lendwangu elilukiwe elincanyana.Igama elithi FR4 liphinde limelele ibanga elisetshenziselwa ukwenza laminates.Isakhiwo se-fiberglass sinikeza ukuzinza kwesakhiwo sezinto ezibonakalayo.I-fiber yengilazi imbozwe nge-epoxy e-flame retardant.Lokhu kunikeza ukuqina kwempahla kanye nezakhiwo eziqinile zemishini.Zonke lezi zici zenza ibhodi lesekethe eliphrintiwe le-FR4 lidume kakhulu phakathi kwabakhiqizi bezinkontileka zikagesi.
