HuaXing as a supplier of high-frequency printed circuit boards (PCBs), we understand the crucial role that high-frequency PCBs play in modern electronic products, particularly in applications with stringent signal integrity and performance requirements. These specialized PCBs are designed to operate effectively at high frequencies, typically above 1 GHz. This article explores high-frequency PCB materials, their characteristics, and applications from a supplier's perspective, providing valuable performance data and practical case studies to help customers make the best choice.
High-frequency PCB materials are specially designed to handle high-frequency signals and ensure signal integrity. Unlike standard PCB materials, high-frequency substrates must meet stringent standards to ensure stable performance in high-frequency environments. As a PCB supplier, HuaXing offers the following primary high-frequency PCB materials:
1.PTFE (Polytetrafluoroethylene)
PTFE, commonly known as Teflon, is a classic choice among high-frequency PCB materials. Its low dielectric constant and low loss tangent make it particularly suitable for high-frequency applications such as microwave and radio frequency.
Key Characteristics:
Dielectric Constant: 2.1 - 2.2
Loss Tangent: 0.0009
Operating Frequency: Up to 110 GHz
2.Ceramic
Ceramic materials (e.g., alumina and barium titanate) offer exceptional electrical performance and high thermal stability. Ceramic materials are ideal for high-frequency applications requiring high reliability and stability.
Key Characteristics:
Dielectric Constant: 6 - 10
Loss Tangent: 0.001 - 0.002
Operating Frequency: Up to 60 GHz
3.HDI (High-Density Interconnect) Laminates
HDI laminates are advanced high-frequency materials with high layer counts and fine line designs, suitable for high-speed data transmission and compact design applications.
Key Characteristics:
Dielectric Constant: 3.0 - 4.0
Loss Tangent: 0.004 - 0.006
Operating Frequency: Up to 20 GHz
4.LCP (Liquid Crystal Polymer)
LCP is a flexible material with excellent electrical performance, suitable for applications requiring high thermal stability and low dielectric loss.
Key Characteristics:
Dielectric Constant: 2.9 - 3.2
Loss Tangent: 0.002 - 0.003
Operating Frequency: Up to 40 GHz
The following table summarizes the performance characteristics of common high-frequency PCB materials to help customers choose the appropriate material:
| Material | Dielectric Constant | Loss Tangent | Operating Frequency |
|---|---|---|---|
| PTFE | 2.1 - 2.2 | 0.0009 | Up to 110 GHz |
| Ceramic | 6 - 10 | 0.001 - 0.002 | Up to 60 GHz |
| HDI Laminates | 3.0 - 4.0 | 0.004 - 0.006 | Up to 20 GHz |
| LCP | 2.9 - 3.2 | 0.002 - 0.003 | Up to 40 GHz |
