What Are The Differences Between Glass Fiber Board, Glass Fiber Board And FR4 Board
Mar 17, 2023
1. Different uses. The production of circuit board is the main raw material is alkali - free glass cloth, fiber paper, epoxy resin. Glass fiber board: substrate glass fiber cloth, epoxy board: the binder is epoxy resin, FR4: substrate cotton fiber paper. All three are fiberglass.
2. Different colors. The general epoxy board on the market is phenolic epoxy, yellow. Not as hard circuit board base material, electrical insulation purposes. FR4 is NEMA specification pure epoxy sheet, the normal color is dark green, which is the color of epoxy. There are also yellow, generally said yellow FR4 called yellow material, white (green) called white material. FR4 is more expensive than epoxy board, and fiberglass board cannot acknowledge the price.
3. Different nature. Glass fiber board with sound absorption, sound insulation, heat insulation, environmental protection, flame retardant and other characteristics. FR-4 also known as fiberglass board; Glass fiber board; FR4 reinforcement plate; FR-4 epoxy resin plate; Flame retardant insulation board; Epoxy plate, FR4 light plate. Epoxy glass cloth plate; Circuit board drilling pad.
Epoxy board, fiberglass board, molecular structure contains active epoxy groups, and a variety of types of curing agent cross-linking reaction to form insoluble, non-melting polymer with a three-way network structure.
