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.

Purpose: in motor and electrical equipment for structural components, including the switch of each style of the `FPC reinforced carbon film for printed circuit board electrical ` ` ` die pad fixture with computer drilling (PCB test) and can be used in damp environment and in 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 * 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).

(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.
