DiClad 527 PCB 20mil Reliable Rogers PCB High Frequency Substrate



Rogers DiClad 527 laminates are at the forefront of Rogers PCB substrate technology. These woven fiberglass reinforced, PTFE-based composite materials have been specifically engineered for use as high-performance printed circuit board substrates. With a carefully controlled ratio of fiberglass reinforcement to PTFE content, DiClad 527 offers a higher dielectric constant (Dk) range, superior dimensional stability, and precise registration capabilities.


Features that Set DiClad 527 Apart:


2.1 DK Range:

DiClad 527 exhibits an impressive DK range of 2.4 to 2.6 at both 10 GHz and 1 MHz, with 50% relative humidity. This ensures consistent and reliable signal transmission across a wide frequency spectrum.


2.2 Low Dissipation Factor:

With a dissipation factor of only 0.0017 at 10 GHz and 0.0010 at 1 MHz, DiClad 527 minimizes signal loss and ensures optimal electrical performance.


2.3 Temperature Coefficient of Dk (TcDK):

DiClad 527 demonstrates exceptional stability in varying temperature conditions, with a TcDK of -153 ppm/°C ranging from -10°C to 140°C at 10 GHz.


2.4 Low Moisture Absorption:

The laminate's low moisture absorption rate of 0.03% guarantees long-term stability and performance, even in high-humidity environments.


2.5 Controlled Thermal Expansion:

DiClad 527 offers a low coefficient of thermal expansion (CTE) in the X and Y axes, with values of 14 ppm/°C and 21 ppm/°C respectively. The Z-axis CTE is 173 ppm/°C, ensuring excellent dimensional stability under varying thermal conditions.



Benefits of DiClad 527:


3.1 Extremely Low Loss Tangent: 

The low loss tangent of DiClad 527 ensures minimal signal attenuation, making it ideal for high-frequency applications that demand precise signal transmission.


3.2 Excellent Dimensional Stability:

3.3 Product Performance Uniformity: 

DiClad 527 is manufactured to rigorous quality standards, ensuring that its electrical properties remain highly uniform across different frequencies, resulting in reliable and predictable performance.


3.4 Consistent Mechanical Performance:

The robust composition of DiClad 527 ensures consistent mechanical performance, allowing for easy fabrication and assembly of PCBs.


3.5 Excellent Chemical Resistance:  

DiClad 527 offers excellent resistance to a wide range of chemicals, ensuring long-term reliability in harsh operating conditions.


3.6 Stable Dk over Wide Frequency Range:

The stable dielectric constant of DiClad 527 over a broad frequency range guarantees predictable electrical performance and consistent signal integrity.


3.7 Low Circuit Losses at High Frequency:

DiClad 527 minimizes signal loss and maximizes signal integrity, even at high frequencies, making it ideal for advanced communication systems.


3.8 Negligible Performance Drift in High Humidity Environments:

DiClad 527 has been engineered to withstand high humidity conditions without compromising performance or reliability, making it suitable for a wide range of applications.
