FR-4 PCB Manufacturer

FR-4 PCB always be called as rigid PCB, according to the hardness of material, and FR-4 material is the most popular material for PCB manufacturing, and the full name is epoxy glass fabric laminated sheet, But there are lots of FR-4 PCB material that have different cost and quality, so you would better to know the FR4 material before manufacturing your FR4 PCB, and you also have to consider that when you evaluate the price of FR4 PCB from your FR4 PCB manufacturer. FR-4 is a kind of code of fire resistant material grade, represented by the mean resin material after combustion state must be able to put out a material specification, it is not a material name, but a level of material, so the general FR - 4 grade materials used in the circuit board has a lot of kinds, but most are based on the so-called four functions (Tera - Function) of epoxy resin and Filler (Filler) and glass fiber made of composite materials.

FR-4 epoxy glass cloth laminate, according to the use of different industries, commonly known as: FR-4 Epoxy Glass Cloth, insulation board, epoxy plate, epoxy resin plate, brominated epoxy resin, glass fiber board, FR-4 board, FR-4 board, glass fiber reinforcing plate, FPC reinforcing plate, flexible circuit board reinforcing plate FR-4, flame retardant epoxy resin board, insulation board, FR-4 laminated board, epoxy board, FR-4 board, FR-4 board, glass fiber epoxy glass cloth plate, epoxy glass cloth laminate, printed circuit board drilling plate. The main technical features and applications: electrical insulation [1] stability, good flatness, smooth surface, no pits, thickness tolerance standard, suitable for application in high performance electronic insulation requirements of products, such as FPC reinforcing plate, PCB drilling plate, glass fiber, carbon film potentiometer meson printing glass fiber board, precision planetary gear (wafer grinding), precision test plate, electrical equipment (Electrical) insulation board and an insulation plate, strip transformer insulation board, insulation parts, grinding gear motor, electronic switch insulation board.

After FR4 PCB, let us learn of  "FR4", FR4 copper clad laminate is the abbreviation of glass fiber epoxy resin.

FR4 copper clad laminate is divided into the following stages:

  •  FR-4 A1 grade copper clad laminate

This level is mainly used in military, communications, computers, digital circuits, industrial instrumentation, automotive electronics and other electronic products. The quality of the series of products to achieve the highest level in the world, the highest grade, the best performance of the product.

  •  FR-4 A2grade copper clad laminate

This level is mainly used for general computer, instrument and meter, high grade home appliance and general electronic products. This series of copper clad laminate is widely used, and all kinds of performance index can meet the needs of general industrial electronic products. Has a very good price performance ratio. Enable customers to effectively improve the price competitiveness.

  • FR-4 A3 grade copper clad laminate

This level of copper clad laminate is the company specifically for the home appliance industry, computer peripheral products and ordinary electronic products (such as toys, calculators, games, etc.) development and production of FR - 4 products. The characteristic is that the performance meets the requirements of the premise, the price highly competitive advantage.

  •  FR-4 A4 grade copper clad laminate

This level of sheet metal is FR-4 clad laminate. But the performance indicators can still meet the needs of ordinary household appliances, computers and general electronic products, the most competitive prices, the price performance is also very good.

  • FR-4 B grade copper clad laminate

This grade of the plate is relatively poor, poor quality stability, does not apply to a larger area of the circuit board products, generally applicable to the size of 100mmX200mm products. Its price is the lowest, should pay attention to choose to use.
