宣城What are the applications of FR4 fiberglass board in electronic circuit boards?

FR4 fiberglass board is a widely used in electronic circuit board (PCB) substrate material, it has the advantages of high temperature resistance, high strength, good heat insulation performance, and convenient production, low cost, so it is widely used in the production of electronic circuit board, in communications, electronics, aerospace and other fields have applications, the following are introduced to its application in electronic circuit board.

1. Single panel: FR4 fiberglass board as a substrate, coated with copper layer becomes a single panel (PCB), it is a simple structure in the electronic circuit board, due to low cost, simple production, so it has been widely used in some electronic products.

2. Double panel: Double panel (PCB) refers to the copper layer on both sides of the FR4 fiberglass board, so more components can be arranged on it, so it is widely used in the production of electronic circuit boards, especially in small and medium-sized products have been applied, such as mobile phones, laptops, electronic watches and so on.

3. Multi-layer board: Multi-layer board (PCB) refers to the FR4 fiberglass board coated with multiple layers of copper, the different layers are connected through the electrolyte layer of the electronic circuit board, its structure is more complex, but because it has more wiring layers and component installation area, it can achieve a more complex circuit design. Multilayer boards are widely used in large electronic equipment, such as computers, automotive electronics, medical equipment and other fields.

4.HDI board: HDI(high-density interconnection) board is a new type of circuit board, which refers to the circuit board that uses micro-holes to achieve high-density interconnection on the FR4 fiberglass board. It can achieve high acceleration, high frequency, make the board smaller, reduce weight, and lower production cost, so it has been widely used in high-performance electronic fields such as communication equipment and smart phones.

5. Flexible board: Flexible circuit board (FPC) is a circuit board made of flexible materials as a substrate. FR4 fiberglass board as one of the most commonly used flexible circuit board substrates, it can be bent, so it has been widely used in some electronic products, such as headphones, card readers, digital cameras and so on.

In summary, FR4 fiberglass board is widely used in electronic circuit boards, according to different electronic equipment needs, using different structural types, from single-layer board to multi-layer board, and then to flexible circuit boards, FR4 fiberglass board is used as the substrate, which provides a guarantee for the performance improvement and miniaturization of electronic equipment.
