Double Sided PCB Board


Ceramic Filled Fiberglass PCB Board

Today, I'm happy to be the host as we delve into the world of RF-60TC high-frequency PCBs, which offer enhanced heat dissipation and remarkably low loss.


RF-60TC is a high-performance PCB material that combines PTFE and ceramic-filled fiberglass substrates. It is specifically designed for high-power RF and microwave applications, delivering superior dielectric heat dissipation and minimal losses. This unique material enables lower operating temperatures for high-power applications and enhances performance and efficiency for miniaturized antenna applications in the 6.15 DK market segment.


Now, let's explore the detailed properties of RF-60TC.


RF-60TC Typical Properties

The dielectric constant (Dk) of RF-60TC is 6.15 ± 0.15 at 10 GHz, while the dielectric loss tangent (Df) is an impressive 0.002.


In terms of electrical properties, RF-60TC boasts a dielectric breakdown voltage of 55 kV and a dielectric strength of 550 V/mil.


Furthermore, RF-60TC exhibits excellent arc resistance, lasting for over 180 seconds. Even after exposure to humidity, the surface resistivity and volume resistivity remain at a remarkable 1.0 x 10^8 Mohm.


Shifting our focus to mechanical properties, the flexural strength in the machine direction (MD) is 10,000 psi, while in the cross direction (CD), it is 9,000 psi.


For tensile strength, RF-60TC demonstrates 9,000 psi in the MD and 7,000 psi in the CD.


The Young's modulus in the MD is measured at 721 kpsi, and the Poisson's ratio in the MD is 0.155.

Regarding dimensional stability, RF-60TC showcases a minimal dimensional change of 0.01 mils/in in the MD after bake, while in the CD, it is 0.69 mils/in. After thermal stress, the dimensional stability reaches 0.06 mils/in in the MD and 0.8 mils/in in the CD.


Moving on to thermal properties, RF-60TC exhibits excellent thermal conductivity. For unclad material, the thermal conductivity is 0.9 W/MK, while for half ounces and 1oz copper, it reaches 1 W/MK and 1.05 W/MK, respectively.


The thermal coefficient of dielectric constant (TCDk) for RF-60TC is -3.581 ppm/°C, and the coefficient of thermal expansion (CTE) is 9.9 ppm/°C for the X and Y axes, with a slightly higher value of 40 ppm/°C for the Z axis.


In terms of physical properties, RF-60TC exhibits a moisture absorption rate of only 0.03%. The peel strength is excellent, with 8 lbs/in for 1 oz. ED copper. It has a density of 2.84 g/cm3 and a specific heat of 0.94 J/gK. The material's thermal decomposition temperature (Td) is 500°C for 2% weight loss and 515°C for 5% weight loss. It also holds a flammability rating of V-0 according to UL 94.
