Low-Cost RF & Microwave PCB Production Services

SFX PCB offers a comprehensive range of RF and microwave substrates including Rogers RO4000 series (RO4003C, RO4350B), ceramic (ALN and Al2O3), transparent glass (tempered, quartz, sapphire), copper core, and copper coin constructions. Each material is selected based on frequency requirements, thermal demands, and application environment to ensure optimal signal performance.

Rogers PCB features a lower and more stable dielectric constant (Dk) compared to FR4's typical ~4.5, along with significantly reduced dielectric loss. This results in superior signal integrity, minimal insertion loss, and consistent electrical performance across wide temperature ranges — making Rogers the preferred choice for RF, microwave, radar, and millimeter-wave circuit designs.

SFX PCB provides official quotation sheets within 24 hours of receiving design files and requirements. Production lead times vary by board type and complexity; standard rigid PCBs typically ship in 5–10 business days, while expedited and rush production services are available upon request for time-sensitive RF prototype projects.

SFX PCB's RF and microwave PCB services are designed for a wide range of industries including Telecommunications & 5G (base stations, RF amplifiers, radar), Aerospace & Defense (radar systems, missile guidance, avionics), Medical Devices (MRI systems, ultrasound, high-frequency diagnostics), and Industrial & Automotive Electronics (EV systems, power modules, and automation). Each substrate and board type is matched to the specific performance and reliability demands of these sectors.

Available surface finishes include ENIG (Electroless Nickel Immersion Gold), ENEPIG, Immersion Silver, Immersion Tin, OSP, HASL, lead-free HASL, hard gold, and soft gold plating. For high-frequency RF boards, ENIG and Immersion Silver are commonly recommended due to their flatness, low contact resistance, and excellent solderability characteristics.

SFX PCB holds ISO 9001:2015, ISO 14001:2015, ISO 13485, and IPC-A-610 Class 2/3 certifications. Products are available in RoHS and REACH compliant versions, and the Rigid FR4 PCB line carries UL listing. These certifications ensure manufacturing quality and regulatory compliance for aerospace, defense, medical, and telecom RF applications.

Yes. SFX PCB seamlessly supports the full production spectrum — from single-piece RF prototypes to high-volume mass production — without requiring customers to switch suppliers. Prototype boards can be assembled from 24 hours once all parts are available, and the same ISO-certified facilities handle scaling to large production runs with consistent quality standards.
