Epoxy rod, FR-4 board insulation board, glass fiber rod

FR-4 is a flame resistant material level code, the meaning is the resin material by burning state can be a self extinguishing material specification, it is not a material name, but a material level, so the FR-4 grade materials currently used on the circuit board has many kinds, but most of all the so-called four function (Tera-Function) of epoxy resin and filler (Filler) and composite material made of glass fiber.

 

Introduction of FR-4 products

FR4 read it verbally, but the written model was FR-4

FR-4 epoxy glass cloth laminate, according to the use of different industries, commonly known as: FR-4EpoxyCloth, epoxy plate, epoxy resin plate, brominated epoxy resin plate, FR-4 plate, glass fiber, glass fiber board, FR-4 reinforcement plate, FPC reinforcement plate, flexible circuit board reinforcing plate, FR-4 epoxy resin board FR-4, flame retardant board, laminated board, epoxy board, FR-4 plate, FR-4 plate glass, glass board, epoxy glass cloth laminate, printed circuit board drilling plate. The main characteristics and application: stable performance, good flatness, smooth surface, no pits, thickness tolerances, suitable for electronic products such as FPC requirements, reinforcement plate, PCB drilling plate, glass fiber meson, carbon film potentiometer printing glass fiber board, precision planetary gear (wafer), precision test plate electrical equipment (Electrical), baffle plate, strip, transformer insulation board, motor parts, gear grinding, electronic switch board etc..

FR4 epoxy glass cloth laminate surface color: Yellow FR-4, white FR-4, black FR-4, basket color FR-4 and so on

FR-4 is the substrate used by PCB, and it is a kind of sheet material. According to the different materials, the main categories are classified as the following four kinds:

1) FR-4: glass cloth substrate

2) FR-1, FR-2 and so on: paper substrate

3) CEM series: composite substrate

4) the FR-4 electronic cloth of the material substrate (ceramic, metal base, etc.) is dipped in epoxy phenolic resin and so on.

Characteristics: it has high mechanical and dielectric properties, good heat resistance and moisture resistance, and has good machinability.

Uses: motor, electrical equipment for structural components, including switches of various styles, `FPC reinforcing appliances, carbon film printed circuit boards, computer drilling pads, mold tooling, etc. (PCB test stand), and can be used in humid environmental conditions and transformer oil.

FR-4 performance characteristics

The vertical layer to the flexural strength of A: normal: E-1 / 150150 + 5 C = 340Mpa

Impact strength parallel to layer (beam method): = 230KJ / M

After soaking resistance (D-24 / 23): = 5.0 * 108.

The vertical layer to the electrical strength (90 + 2 C in transformer oil, the thickness is not less than 14.2MV / M 1mm)

Parallel to the layer. The breakdown voltage (90 + 2 C in transformer oil): = 40KV

The relative dielectric constant (50Hz = 5.5).

The relative dielectric constant (1MHz = 5.5).

The dielectric loss factor (50Hz = 0.04).

The dielectric loss factor (1MHz = 0.04).

Water absorption (D-24 / 23 1.6mm in thickness): less than 19mg

Density: 1.70-1.90g / cm3

Flammability: FV0

Color: true color

Executive standard: GB / T1203.1-1998

FR-4 process performance:

(1) melting point of FR-4 process board (203 C)

(2) high resistance to chemicals

(3) low loss coefficient (Df0.0025)

(4) stable and low dielectric constant (Dk2.35)

(5) thermoplastic materials

Brief introduction of materials

Epoxy resins refer to macromolecular compounds containing two or more epoxy groups in the molecule, except for some of them, and their relative molecular mass is high. (two). The molecular structure of epoxy resin in the molecular chain with lively epoxy group as its characteristic, the epoxy groups can be located in the end of the chain, or intermediate molecules into ring like structures. Because the molecular structure of epoxy containing active curing agent, so that their various types of crosslinking reaction and the formation of insoluble and infusible polymers with three direction mesh structure.

Application characteristics

1, diverse forms. The resin, curing agent and modifier system can meet the requirements of the application form. The range of the resin can be from low viscosity to high melting point solid.

2, easy curing. The epoxy resin system can be cured in the temperature range of 0~180 degrees with different curing agents.

3, strong adhesion. The existence of hydroxyl and ether bonds in the molecular chain of epoxy resin makes it highly adhesive to the material. The shrinkage of epoxy resin is low and the internal stress is small, which is also related to the adhesion strength of epoxy resin.

4, low contractility. The epoxy resin and the curing agent reacts by direct addition reaction or resin molecules of the epoxy group ring opening polymerization, no water or other volatile by-products release. Compared with unsaturated polyester resin and phenolic resin, they show very low shrinkage (less than 2) during curing.

Epoxy board, 3240 epoxy board
