FR4 Vs.FR5

1. What is FR-4 board?

FR-4 is fiberglass epoxy resin copper-clad laminate, a kind of base material in circuit boards. In fact, you should have seen it. For example, when the small game console is disassembled, the green board inside is made of FR-4. circuit board.

FR4 FR5 epoxy board is a plate-shaped laminated product made of special electronic cloth impregnated with epoxy phenolic resin and other materials and hot pressed under high temperature and high pressure. It has high mechanical properties and dielectric properties, good insulation properties, heat resistance and moisture resistance, and has good machinability. Application: used as insulating structural parts in motors and electrical equipment, and is also widely used For PCB testing; and can be used in humid environmental conditions and transformer oil.

2. What are the specific differences between FR5 sheets and FR4 sheets?

FR-4 is the code name for a flame-resistant material grade. It means that the resin material must be able to self-extinguish after burning. It is not a material name, but a material grade. Therefore, the current general circuit There are many types of FR-4 grade materials used in boards, but most of them are composite materials made of so-called tera-function epoxy resin plus filler and glass fiber.

FR-4 epoxy glass cloth laminate, according to different uses, is generally called in the industry: FR-4 Epoxy Glass Cloth, insulation board, epoxy board, epoxy resin board, brominated epoxy resin board, FR-4 , fiberglass board, fiberglass 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 , FR-4 light board, FR-4 fiberglass board, epoxy glass cloth board, epoxy glass cloth laminate, circuit board drilling pad.

Main technical features and applications: electrical insulation, stable performance, good flatness, smooth surface, no pits, standard thickness tolerance, suitable for products with high performance electronic insulation requirements, such as FPC reinforcement boards and PCB drilling pads , fiberglass meson, potentiometer carbon film printed fiberglass board, precision planetary gear (wafer grinding), precision test plate, electrical (electrical) equipment insulating stay partition, insulating pad, transformer insulating board, motor insulating parts, grinding Gears, electronic switch insulation boards, etc.

FR-5 has better advantages than FR-4:

1. TG and TD are higher;

2. Better heat resistance, about twice that of ordinary FR-4;

3. Z-CTE is smaller and suitable for high multi-layer boards;

4. T288 is better.

FR4FR5 epoxy board is a plate-like laminated product made of special electronic cloth impregnated with epoxy phenolic resin and other materials and hot pressed under high temperature and high pressure. It has high mechanical properties and dielectric properties, good insulation properties, heat resistance and moisture resistance, and has good machinability. Application: used as insulating structural parts in motors and electrical equipment, and is also widely used For PCB testing; and can be used in humid environmental conditions and transformer oil.

The fr4 board cited above is a flame-resistant material with good performance and is often used in the electronic and electrical industry. It has stable performance and still has good mechanical strength and electrical performance at higher temperatures. In addition, because most fr4 boards use imported raw materials and are carefully manufactured through standard processes, they have the advantages of raw materials, ensuring high quality and low price, and enjoy a good reputation and sales at home and abroad. This is also the key to the development of fr4 boards and their increasingly widespread applications.
