Top PCB Board Shops in the USA: Expert Guide to RF & Microwave Manufacturers

Rogers PCBs use advanced low-loss laminates from Rogers Corporation — such as RO4003C and RO4350B — offering a stable, low dielectric constant and far lower dielectric loss than standard FR4. They are the preferred choice for RF, microwave, radar, antenna, and millimeter-wave circuit designs where consistent signal integrity and minimal insertion loss are critical at high frequencies.

Yes. FX PCB seamlessly scales from rapid prototyping — with official quotations in 24 hours and boards assembled from 24 hours once parts are available — through to large-volume mass production. Customers can prototype and scale production without switching suppliers, ensuring consistent quality and design continuity across all order volumes.

FX PCB holds ISO9001, ISO14001, and ISO13485 certifications, and conforms to IPC-A-610 Class 2 and Class 3 assembly standards. Products are manufactured in compliance with RoHS and REACH directives. The Rigid FR4 PCB line is also UL listed. These certifications make FX PCB suitable for medical, aerospace, military, and industrial applications.

FX PCB offers a wide range of surface finishes depending on the board type, including HASL (lead and lead-free), ENIG (Electroless Nickel Immersion Gold), ENEPIG, Immersion Silver, Immersion Tin, OSP (Organic Solderability Preservative), Soft Gold, Hard Gold, and Gold Plating. The appropriate finish depends on the application's solderability, shelf life, and frequency requirements.

Metal Core PCBs (MCPCBs) use an aluminum or copper base layer instead of FR4 fiberglass, enabling heat dissipation up to 9x faster than standard FR4 boards. This makes them ideal for high-power LED lighting, automotive electronics, and power supply devices where thermal management is critical. Standard FR4 PCBs are more cost-effective for general-purpose and lower-power applications.
