Introduction to the Grade of FPC Copper Clad Plate

1. FR-4 A1 grade copper clad plate is mainly used in electronic products such as military, communication FPCs, computers, digital circuits, industrial instruments and meters, and automotive circuits. The quality of this series of products has completely reached the world-class level, with the highest grade and best performance.

2. FR-4 A2 grade copper clad plate is mainly used for ordinary computers, instruments and meters, high-end household appliances, and general electronic products. This series of copper clad plates is widely used, and all performance indicators can meet the needs of general industrial electronic products. There is a good price performance ratio. Can effectively improve customer price competitiveness. 3. FR-4 A3 grade copper clad plate is a FR-4 product developed and produced specifically for the home appliance industry, computer peripheral products, and ordinary electronic products (such as toys, calculators, game consoles, etc.). Its characteristic lies in its competitive price while meeting the performance requirements.

4. FR-4 AB grade copper clad plate is a unique low-end product. However, all performance indicators can still meet the needs of ordinary household appliances, computers, and general electronic products, with the most competitive price and excellent performance to price ratio.

5. Secondary products such as FR-4 B-grade copper clad plate have poor quality stability and are not suitable for circuit board products with large areas. They are generally suitable for products with dimensions of 100mmX200mm. Its price is the cheapest, but customers should pay attention to choosing to use it.

6. The CEM-3 series copper clad panels are produced in three substrate colors, namely white, black, and natural. Mainly used in the computer, LED industry, clocks, general household appliances, and ordinary electronic products (such as VCDs, DVDs, toys, game consoles, etc.). Its main feature is good punching performance, which is suitable for large-scale PCB products that require stamping process forming. This series of products has three quality levels: A1, A2, and A3. Customers with different requirements can choose to use them.

7. This series of products has three quality levels: A1, A2, and A3, with black base color copper clad plates for various types of clocks and watches. There are two types of copper clad plates, FR-4 and G10. Its quality indicators such as thickness, blackness, and solubility fully meet the requirements of clock products. The quality of the A1 series of such panels has reached world-class levels, and many advanced quartz watches abroad choose this series of panels. The quality of A3 grade products meets the quality level required by ordinary watches, and the price is the most competitive.

8. Multilayer board materials provide customers with the following types of multi-layer materials: 1) prepreg (1080, 2116, 7628, etc.), 2) copper foil (0.5 OZ, 1.0 OZ, 1.5 OZ, 2.0 OZ, 3OZ, etc.), 3) release film, 4) Kraft paper for lamination.

9. High performance aluminum based copper clad plate

10. High Tg value copper clad plate, high CTI (compared to leakage marking index) copper clad plate, etc.
