 RF-45 62mil material PCB

RF-45 PCB property:

The RF-45 62mil material PCB has a moisture absorption rate of ≤0.04%, keeping the board free from moisture-related issues. It boasts impressive flexural strength, with a value of 20,700 psi in the machine direction (MD) and 19,300 psi in the cross-machine direction (CD), as per ASTM D790 testing. This strength ensures the durability and longevity of the PCB.


Featuring a peel strength of 10 lbs/linear inch for 1 oz VLP (very low profile) copper, the RF-45 PCB exhibits strong adhesion between the copper and the substrate. This peel strength, determined through IPC-TM-650 2.4.8 (Thermal Stress) testing, ensures the integrity of the board during thermal cycling.


With a thermal conductivity of 0.33 W/m/K, theTaconicRF-45 PCB effectively dissipates heat, preventing thermal buildup and ensuring reliable performance. It exhibits a volume resistivity of 1.4 x 10^8 Mohm/cm and a surface resistivity of 3.3 x 10^6 Mohm, as per IPC-TM-650, indicating excellent electrical insulation properties.


The RF-45 PCB 1.575mm has a coefficient of thermal expansion (CTE) of 9 ppm/°C in the x-axis, 13 ppm/°C in the y-axis, and 96 ppm/°C in the z-axis, as per IPC-TM-650-2.4.41 (>RT -125℃) testing. These CTE values ensure dimensional stability and prevent issues such as warping or delamination during temperature variations.


With a flammability rating of UL94 V-0, the RF-45 PCB meets the highest standards for flame retardancy, ensuring safe operation in various environments.


RF-45 PCB typical applications:

The RF-45 PCB finds typical applications in satellite radio antennas, RFID antennas, and GPS antennas. Its high-performance characteristics, such as low loss, stable DK, and temperature range, make it ideal for these RF applications.


Overall, the RF-45RF PCB is a reliable and efficient solution for RF circuit designs, offering excellent signal integrity, stability, and durability. Its material properties, construction details, and compliance with industry standards make it a preferred choice for RF applications worldwide.
