Rigid-Flex PCB Supplier for OEM & EMS Companies

Rigid-flex PCBs are widely used in aerospace and defense (radars, night vision, guidance systems), medical devices (defibrillators, hearing aids, ultrasound), automotive electronics (ABS, dashboards), telecommunications (smartphones, base stations), industrial automation, and wearable technology. Their compact, durable structure makes them ideal wherever space, weight, and reliability are critical requirements.

SFX PCB's rigid-flex boards support up to 20 total layers, with the flexible (FPC) section supporting up to 12 layers. This multilayer capability enables complex, high-density interconnect designs for advanced consumer electronics, aerospace systems, and medical instrumentation that demand robust signal integrity and compact form factors.

SFX PCB uses premium base materials including Polyimide (PI) for the flexible sections due to its excellent thermal and mechanical properties, and FR4 or Rogers materials for the rigid sections. Trusted material brands include Shengyi, DuPont, Taiflex, Boyu, and ITEQ, selected based on the application's thermal, electrical, and mechanical requirements.

Available surface treatments include ENIG, Immersion Silver, Immersion Tin, OSP, ENEPIG, Soft Gold, Gold Plating, and HAL Lead-free. ENIG is commonly chosen for fine-pitch components, while OSP and HAL Lead-free suit cost-sensitive RoHS-compliant applications. The right finish depends on your solderability requirements, operating environment, and shelf-life expectations.

SFX PCB manufactures rigid-flex PCBs to ISO 9001:2015 and ISO 14001:2015 quality and environmental standards, with IPC Class II compliance on every board shipped. All boards undergo AOI, flying probe electrical testing, impedance testing, solderability testing, and dimensional inspection. The company also holds ISO 13485 certification relevant to medical device supply chains.

Yes. SFX PCB is structured to support the complete product lifecycle — from single prototype units to high-volume mass production — without requiring customers to switch suppliers. Prototyping services include engineering consultation, DFM analysis, and fast turnaround. Volume pricing is available on request, with custom quotes issued within 8 hours of receiving PCB design files.
