Hot Air Solder Leveling PCB Blog


Digital Radio Antennas Microwave PCB


Today we'll be discussing a high-frequency PCB with a lower dielectric constant called DiClad 870 microwave PCB.


DiClad 870 is a Rogers laminate that utilizes woven fiberglass reinforced, PTFE-based composites. This unique composition enables a stable, lower dielectric constant by reducing the number of fiberglass plies and increasing the PTFE content. As a result, it supports wider line widths, reducing insertion loss.


Now, let's dive into the data sheet to explore the properties of DiClad 870.


Typical Properties of DiClad 870

DiClad 870 exhibits excellent electrical properties. It has a dielectric constant of 2.33 at both 1 MHz and 10 GHz, with a low dissipation factor of 0.0009 at 1 MHz and 0.0013 at 10 GHz.


The thermal coefficient of dielectric constant ranges from -161 ppm/°C to -10°C to +140°C.


DiClad 870 boasts a high volume resistivity of 1.5 x 10^9 MΩ-cm and a surface resistivity of 3.4 x 10^7 MΩ.


Moreover, it demonstrates an impressive arc resistance of over 180 seconds, tested according to ASTM D-495 using the D48/50 method. Similarly, the dielectric breakdown voltage exceeds 45 kV, tested according to ASTM D-149 using the D48/50 method.


In terms of mechanical properties, DiClad 870 exhibits a peel strength of 14 lbs. per inch after thermal stress. It also shows excellent tensile modulus, tensile strength, compressive modulus, and flexural modulus at 23°C.


When it comes to thermal properties, DiClad 870 offers a low coefficient of thermal expansion of 17 ppm/°C (X axis), 29 ppm/°C (Y axis), and 217 ppm/°C (Z axis) within the temperature range of 0°C to 100°C. However, its thermal conductivity is only 0.257 W/mK at 100°C.

DiClad 870 meets the UL94-V0 flammability rating, ensuring its safety.


Let's now explore the physical properties of DiClad 870.


It has a density of 2.26 g/cm3 at 23°C, indicating its dense and sturdy nature.


With a water absorption rate of 0.02%, DiClad 870 demonstrates low water absorption.


Lastly, let's look at the outgassing characteristics.


Outgassing refers to the release of volatile materials during use. DiClad 870 shows minimal outgassing with a total mass loss of 0.02%, collected volatile condensable material of 0.00%, and water vapor regain of 0.01% at 125°C and ≤ 10^-6 torr, with no visible condensate.
