The surface colors of FR-4 epoxy glass cloth laminated sheet are:

Yellow FR-4, white FR-4, black FR-4, blue FR-4, etc.

FR-4 is the substrate used in PCB and is a type of sheet material. According to the different reinforcement materials, the sheet materials are mainly classified into the following four types:

1) FR-4: Glass cloth substrate

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

3) CEM series: Composite substrate

4) Special material substrates (ceramic, metal substrates, etc.)

FR-4 is a laminated plate made of special electronic cloth impregnated with epoxy phenolic resin and other materials under high temperature and high pressure.

Features: high mechanical properties and dielectric properties, good heat resistance, moisture resistance and good mechanical processing.

Application: insulation structure parts used in motor and electrical equipment, including various types of switch, FPC reinforced, electrical insulation carbon film printed circuit board, computer drilling pad/jig (PCB test rack), and can be used in humid environment conditions and transformer oil.

FR-4 epoxy glass fiber board (epoxy plate): the main material is imported half curing film. Color is white, yellow and green. It still has high mechanical strength under the normal temperature of 150 ℃. Electrical properties and flame retardant are good under dry and wet state. FR-4 epoxy glass fiber board adopts imported raw materials, domestic compressor and elaborate manufacturing standard process; The main specifications are 1000*2000 mm and 1020mm*1220mm. Because of the advantages of raw materials, we will ensure superior quality, low price and timely delivery. ZTelec Group has a stable customer base at home and abroad, and enjoys a high reputation.
