FR-4 Fiberglas Bord

FR-4 material is a fire code rating, the mean resin represented by the state must be able to extinguish the burning of a material specification, it is not a material name, but a material level, so the current general circuit boards for the FR-4 grade, there are many types, but most are based on four-function (Tera-Function) of the epoxy resin with fillers (Filler) and made of glass fiber composite materials. Main Characteristics (1)Stable electrical insulation properties. (2)Good flatness, smooth surface, no pits. (3)High mechanical property and dielectric properties. (4)Good heat resistance and resistant to moisture resistance. (5)Good mechanical workability. Application area Requirements for high performance electrical insulation products, such as FPC Stiffener, PCB drilling plate, glass meson, carbon film printing glass fiberboard potentiometer, precision planetary gears (grinding chips), precision test plates, electrical (electrical ) equipment insulation stays partitions, insulation pads, transformer insulation boards, electrical insulation parts, grinding gears, electronic switch insulation boards. Specification size Color: White,Green Thickness: 0.3mm-20mm length and width: 1020mm×1220mm
