Glass fiber epoxy copper clad laminate is referred to as FR-4 copper clad laminate. According to the quality requirements of the application, it can be divided into the following grades:
FR-4 A1 copper clad laminate
This grade of copper clad laminates are mainly used in military industry, communications, computers, digital circuits, industrial instrumentation, automotive circuits and other electronic products. This grade of copper clad laminates are widely used, and all technical performance indicators meet the needs of the above-mentioned electronic products. The quality of this grade product has reached the world-class level.
FR-4 A2 copper clad laminate
This grade of copper clad laminates are mainly used for ordinary computers, advanced home appliances and general electronic products. This grade series of copper clad laminates are widely used, and each performance index can meet the needs of general industrial electronic products. It has good price-performance ratio, which enables customers to effectively improve their competitiveness.
FR-4 A3 copper clad laminate
This level of copper clad laminate is an FR-4 product developed and produced by our company specifically for the home appliance industry, computer peripheral products and ordinary electronic products (such as toys, calculators, game consoles, etc.). Its characteristic is that the price is extremely competitive under the premise that the performance meets the requirements.
FR-4 A4 copper clad laminate
This grade of laminate material is the low-end material of FR-4 copper clad laminate. However, various performance indicators can still meet the needs of ordinary home appliances, computers and general electronic products. Its price is the most competitive, and the performance-price ratio is also quite excellent.
FR-4 B grade copper clad laminate
This grade of laminate material is relatively inferior and has poor quality stability. It is not suitable for circuit board products with a large area. It is generally suitable for products with a size of 100mmX200mm, such as making ordinary double-sided PCB FR-4 products with low requirements on line spacing, line width, hole spacing and aperture. Its price is the cheapest, so users should pay attention to choosing it.
FR-4 halogen-free copper clad laminate
This series of products is the future development trend of CCL environmental protection, which can be used in military industry, communications, computers, digital circuits, industrial instruments, automotive circuits and other electronic products. The quality of this grade product has reached the world-class level.
CEM-3 Series Copper Clad Laminate
This type of product is produced in three colors, white, black and natural color. Mainly used in computers, LED industry, clocks and watches, general household appliances and general electronic products (such as VCD, DVD, toys, game consoles, etc.). The main feature is good punching performance, which is suitable for large quantities of PCB products that require stamping process forming. This series of products have three quality grades: A1, A2, and A3. Customers with different requirements can choose them.
