The description of FR4 glass fiber laminated board

FR4 glass fiber laminated board is a rigid plate-shaped insulating material made of alkali-free glass fiber cloth impregnated with epoxy resin and hot pressed. The IEC standards are subdivided into EPGC 201, EPGC 202, EPGC 203, EPGC 204, EPGC 306, EPGC308 and other different levels; NEMA (National Electrical Industry) standards are divided into G10, FR-4, G11, FR-5, etc. level.

FR4 glass fiber laminated board has the following properties: good electrical performance in high humidity environment, good mechanical performance at medium temperature, voltage resistance, flame retardancy (FR series), stable product quality, etc. . It can be processed into various parts by lathe processing, stamping, trimming, drilling, sandblasting, grinding, sawing and milling.

FR4 glass fiber laminated board are widely used in motors, electrical equipment, circuit breakers, switch cabinets, transformers, DC motors, AC contactors, explosion-proof electrical appliances, starwheels, low-voltage electrical insulation separators, etc., electrical, electronic, automotive industries and other fields.

The applications of FR4 glass fiber laminated board

It use in frame type circuit breakers: safety baffle, safety shutter, interval liner, phase interval plate, etc.

FR4 glass fiber laminated board is suitable for molded case circuit breakers: phase partition board, tripping board, etc.

Applications in motors: motor armature parts, movable covers, slot wedges, fixed pads, thin gaskets, carbon brush holders, etc.

Application in medium and high voltage switchgears: front, back, top and bottom partitions and phase partitions in partition systems; structural supports for switches and transformers, busbar clamps, etc.

Application in power distribution cabinets: partitions, liners, wiring boards, interphase insulating plates, bottom partitions, contact supports.

The features of FR4 glass fiber laminated board

The surface colors of FR4 glass fiber laminated board are: yellow FR-4, white FR-4, black FR-4, blue FR-4, etc.

FR4 glass fiber laminated board is a substrate used for PCBs, which is a category of sheet materials. Sheet materials are classified into the following four types according to different reinforcing materials:

1) FR4 glass fiber laminated board: glass cloth substrate

2) FR-1, FR-2, etc .: paper substrate

3) CEM series: composite substrate

4) Special material substrates (ceramics, metal bases, etc.) FR4 glass fiber laminated board

is a plate-shaped laminate made by special electronic cloth impregnated with epoxy phenolic resin and other materials after high temperature and high pressure hot pressing.

Features: It has high mechanical properties and dielectric properties, good heat resistance and moisture resistance and good machinability.

The applications of FR4 glass fiber laminated board

The main material of FR4 glass fiber laminated board is imported prepreg, the color is white, yellow, green, and still has high mechanical strength at normal temperature 150 ℃ with good electrical performance in dry state, wet state combustion, insulation components for electrical, electronic and other industries, carefully manufactured using imported raw materials, domestic presses and standard processes; the main specifications are 1000 * 2000mm 1020mm * 1220mm, because of the advantages of raw materials, ensuring high quality and low price , Timely delivery, has a solid customer base at home and abroad, and enjoys a high reputation.
