The FR4 printed circuit board is a type of printed circuit board with “glass fiber cloth + epoxy resin” as its core substrate. “FR4” represents the 4th level of flame retardancy standard (NEMA certification), and it possesses three core characteristics: insulation, mechanical strength, and flame retardancy. Its structure is like “glass fiber framework + resin matrix”. It is the “universal foundation” in fields such as consumer electronics and industrial control.

Our core advantage: Complete control over the entire production process, from materials to craftsmanship.

Customized system: According to different application scenarios, we offer a variety of formulations with low loss (Df ≤ 0.015), high-temperature tolerance (Tg ≥ 170℃), halogen-free and environmentally friendly properties. The dielectric constant can be precisely controlled within the range of 4.0 – 4.8, suitable for high-frequency and high-temperature scenarios such as 5G and automotive electronics.

Micron-level manufacturing accuracy: Utilizing laser drilling (with positioning error of ±2μm) and stepped laminating technology, the minimum line width reaches 0.08mm, and the inter-layer alignment error is less than 5μm. This ensures the stable operation of high-density components, with a yield rate 10% higher than the industry average.

Full-scenario adaptability: Covers thickness specifications ranging from 0.2mm to 3.2mm. Through moisture-proof edge sealing and gold plating processes, it can withstand temperature differences of -40℃ to 125℃ and is suitable for all scenarios from smart watches to industrial control cabinets.

The cost-effective advantage of FR4 printed circuit board: The optimal solution for balancing performance and cost

Compared to substrates such as FR-5 and PTFE, our FR4 printed circuit board not only enhances reliability by 50%, but also reduces the batch cost by over 30%. Through large-scale production and formula optimization, we achieve “performance without compromise, cost more controllable”, which is particularly suitable for orders of 100,000 pieces or more, helping customers enhance their product competitiveness.
