What Are The Characteristics And Application of FR4 Sheet?

What is FR4 ?

FR-4 is a flame-resistant material grade code, which means that the resin material must be able to self-extinguish after the combustion state of a material specification, it is not a material name, but a material grade, so the general circuit boards used in the FR-4 grade of material there are many kinds, but most of the so-called four-function (Tera-Function) epoxy resin, plus filler (Filler) and glass fibers made of composite materials. However, most of them are made of the so-called four-function (Tera-Function) epoxy resin, plus filler and glass fiber composite materials.

FR-4 Epoxy Glass Cloth Laminate, according to the use of different purposes, the industry is generally known as: FR-4 Epoxy Glass Cloth, insulation board, epoxy board, epoxy resin board, brominated epoxy resin board, FR-4, fiberglass board, glass fiber board, FR-4 reinforced board, FPC reinforced board, flexible circuit board reinforced board, FR-4 epoxy resin board, flame-retardant insulation board, FR-4 laminated board, epoxy board, epoxy board, epoxy board, epoxy board, epoxy board, epoxy board, epoxy board, epoxy board, epoxy board, epoxy board, epoxy board, epoxy board, epoxy board. 4 laminated boards, epoxy boards, FR-4 light boards, FR-4 glass fiber boards, epoxy glass cloth boards, epoxy glass cloth laminates, circuit board drilling pads. Main technical characteristics and applications: electric insulation [1] stable performance, good flatness, smooth surface, no pits, thickness tolerance standards, suitable for application in high-performance electronic insulation requirements of the product, such as FPC reinforcement board, PCB drilling pads, fiberglass dielectrics, potentiometer carbon film printed fiberglass boards, precision vernier gears (wafer milling), precision test panels, electrical (electrical) equipment, insulated spacer strip spacer, Insulation pads, transformer insulation boards, motor insulation parts, grinding gears, electronic switch insulation boards, etc.

What are the characteristics of fr4 sheet?

1, High temperature resistance: FR4 sheet has good high temperature resistance, can withstand temperatures up to 180 ℃. This makes it widely used in electronic equipment, such as computer motherboards, power adapters and so on.

2, Good corrosion resistance: FR4 sheet has strong corrosion resistance, can resist the erosion of most chemicals, has a long service life.

3, High mechanical strength: FR4 sheet has high mechanical strength, can resist external shock and vibration, to protect the internal circuitry of the equipment.

4, Good insulation properties: FR4 sheet has good insulation properties, can effectively prevent current leakage and electromagnetic interference, to protect the normal operation of the circuit.

5, Good dimensional stability: FR4 sheet in the manufacturing process has good dimensional stability, not easy to deform, to ensure the accuracy and reliability of the circuit board.

6, Good environmental protection: FR4 sheet is made of environmentally friendly materials, non-toxic and harmless, will not cause harm to the environment and human body.

Application of FR4 sheet

FR4 sheet has a wide range of uses, mainly in electronics, electrical, communications, aerospace and other fields. The following are its main uses:

1. Circuit boards

In electronic manufacturing, FR4 sheet is usually used in the manufacture of circuit boards. It can be used as a substrate material for circuit boards to ensure the stability and reliability of circuit boards.

2. Spacer and isolation material

FR4 sheet has superb insulating properties and high temperature stability, so it can be used as a bulkhead and isolation material in the power system. This not only ensures the electrical safety of the equipment, but also avoids accidents caused by electrical faults.

3. Mechanical parts

FR4 sheet can also be used as a material for mechanical parts, such as machine tool partitions and automobile engine covers. It has excellent mechanical properties and chemical stability, and can be used in different mechanical systems.
