Introducing the newly shipped PCB based on RF-35A2 Substrate.RF-35A2 is a cutting-edge PCB material designed to deliver exceptional performance in high-frequency applications. With its ultra-low fiberglass content and homogeneous dielectric constant, RF-35A2 achieves unparalleled insertion loss properties and optimal power transfer, making it the top choice for power amplifiers, filters/couplers, high-speed digital circuits, passive components, and wireless antennas.

RF-35A2 stands out with its ultra-low loss power amplifier substrate, providing an ideal platform for power amplifiers with minimal signal degradation and maximum efficiency. Its dielectric constant (Dk) of 3.5 at 10 GHz ensures consistent signal propagation and minimizes impedance variations, thanks to its homogeneous Dk throughout the laminate.

Exceptionally low dissipation factor is another notable feature of RF-35A2. With a dissipation factor of 0.0015 at 10 GHz and 23°C, RF-35A2 enables maximum power transfer while minimizing heat generation. This characteristic allows for efficient power amplification without sacrificing performance.

RF-35A2 exhibits low coefficients of thermal expansion (CTE) with x and y values of 10 ppm/°C and 13 ppm/°C, respectively. These low CTE values contribute to the material's dimensional stability and reliability, making it an excellent choice for surface mounting of chip carriers.

Manufactured using a proprietary multi-step process, RF-35A2 ensures excellent copper peel adhesion. This superior adhesion enhances the reliability and durability of connections between copper layers and the substrate, providing a solid foundation for your PCB design.

In addition to its outstanding electrical properties, RF-35A2 offers several benefits. Its Dk tolerance of ± 0.05 ensures consistent performance across production batches, while excellent peel strength (1 oz. VLP) of 12 lbs/in guarantees secure copper adhesion even under demanding conditions. With a low moisture absorption of 0.03%, RF-35A2 maintains stability and reliability in various environments. The material also facilitates ease of drilling, streamlining the PCB manufacturing process.

This 2-layer rigid PCB constructed with RF-35A2 features a copper layer thickness of 35 μm (1 oz) for optimal conductivity. The RF-35A2 layer has a thickness of 0.127 mm (5 mil), providing the desired electrical properties. The board dimensions are 76.04mm x 33.18mm (1PCS) with a tolerance of +/- 0.15mm, ensuring precise dimensions for your specific requirements. The PCB undergoes 100% electrical testing prior to shipment, ensuring its reliability and adherence to quality standards.

With 23 components and 56 total pads, including 45 thru-hole pads and 11 top SMT pads, this PCB offers versatility for various applications. It includes 24 vias and 2 nets, providing flexibility in circuit connections. The PCB is compatible with Gerber RS-274-X artwork files and manufactured to meet the IPC-Class-2 quality standard, guaranteeing reliability and consistent performance.

RF-35A2 PCBs are available for worldwide purchase, allowing engineers and manufacturers from all regions to benefit from their exceptional quality. Unlock the potential of RF-35A2 in your high-frequency applications, such as power amplifiers, filters/couplers, high-speed digital circuits, passive components, and wireless antennas.
