Rigid-Flex PCBs with Metal-Backed Options

Metal-backed PCBs use aluminum, copper, or ceramic substrates instead of standard FR4 to dramatically improve thermal conductivity and mechanical stability. They are best suited for high-power applications such as LED lighting, power converters, automotive electronics, and RF systems where effective heat dissipation is critical to component longevity and circuit performance.

These PCBs serve aerospace, military, medical devices, automotive, telecommunications, industrial automation, and LED lighting industries. Applications range from radar systems and defibrillators to EV power modules, 5G base stations, and high-density consumer electronics — anywhere reliability, thermal management, and space efficiency are non-negotiable requirements.

SFX PCB's Rigid Flex PCBs support up to 20 total layers, with the flexible (FPC) section accommodating up to 12 layers. Advanced laser drilling down to 4mil and inner layer line widths as fine as 1.5mil enable high-density interconnects, making them suitable for complex multilayer designs in aerospace, defense, and high-speed digital applications.

SFX PCB holds ISO 9001:2015 and ISO 14001:2015 certifications for quality and environmental management. Boards also comply with IPC Class II/III standards and RoHS and REACH regulations. The ISO 13485 certification further qualifies the company for medical device PCB manufacturing, ensuring stringent traceability and process control across all product lines.

SFX PCB provides stack-up designs and pricing quotations within 8 hours of receiving your PCB files. Prototypes can be assembled as quickly as 24 hours once all components are available. Lead times for mass production vary by complexity, layer count, and order volume — contact the team directly for project-specific timelines.

Yes. SFX PCB supports seamless scaling from single prototypes to high-volume mass production without requiring a supplier change. Every order includes free DFM (Design for Manufacturability) analysis, ensuring design issues are resolved early to avoid costly rework. This end-to-end capability reduces time-to-market and total production cost significantly.
