DIFFERENCES BETWEEN FR4/G10/G11 EPOXY SHEET
FR4 epoxy board is actually a laminate sheet. There are many types of epoxy sheets, do you know how to distinguish them?
Epoxy board is a laminated board, mainly made of epoxy resin adhesive and paper, cotton, cloth and other substrates. There are many types of epoxy boards, including 3240 epoxy boards, FR4 boards, G11 epoxy boards and G10 laminates. Their performance is similar, but the details are different. See below:
A. Basic parameters difference:
|Product name||Origin of the name||Material composition||Colour||Temperature resistance||Flame retardant|
|FR4||FR-4 is a code name for the grade of flame resistant material, which means that the resin material must be able to extinguish itself after combustion||Electronic grade fiberglass cloth (7628) + epoxy resin||White (natural), aqua green, black, yellow||130℃||UL94-V0|
|G10 SHEET||"G" stands for glass fiber and "10" stands for 10% of the glass fiber||Aqua, green||155℃||HB|
|3240 EPOXY SHEET||/||Electronic grade fiberglass cloth (7628) + epoxy resin||Yellow||130℃||HB|
B. Product property difference:
|EPGC201||Higher mechanical and electrical properties, better heat resistance, moisture resistance products.|
|EPGC202||Performance similar to EPGC201, flame retardation increased to UL F-V0 level.|
|EPGC203||Pormance similar to EPGC201, improved heat resistance, high mechanical strength at high temperature, excellent electrical and anti-static properties.|
|EPGC204||Performance is similar to EPGC203, and the flame retardancy is improved to UL F-V0.|
|EPGC306||Performance similar to EPGC203, improved the resistance to electric trace.|
|EPGC308||Performance similar to EPGC203, improved heat resistance, mechanical stability at high temperature.|
