Rigid Flex PCB Suppliers in China

SFX PCB's rigid flex boards support 1 to 20 total layers, with the flexible FPC section supporting up to 12 layers. This wide range accommodates everything from simple two-layer interconnects to highly complex multilayer configurations required by aerospace, military, and medical electronics.

Rigid flex PCBs from SFX PCB are manufactured using polyimide (PI) for the flexible sections and FR4 for the rigid sections. Rogers material is also available for high-frequency or RF-critical designs. Material brands include Shengyi, Dupont, Taiflex, Boyu, Rogers, and ITEQ.

SFX PCB offers ENIG, Immersion Silver, Immersion Tin, OSP, ENEPIG, Soft Gold, and Gold Plating surface finishes. ENIG and HAL Lead-free options are particularly popular for applications requiring excellent solderability, oxidation resistance, and RoHS compliance.

Rigid flex PCBs are widely used in aerospace and defense (radars, night vision, guidance systems), medical devices (defibrillators, hearing aids, ultrasound), automotive (ABS, dashboards), telecommunications (smartphones, base stations), wearables, and industrial electronics where space, weight reduction, and 3D routing flexibility are critical.

Yes. SFX PCB holds ISO 9001:2015 and ISO 14001:2015 certifications. Their manufacturing processes support RoHS and REACH compliance through lead-free surface treatment options such as HAL Lead-free. IPC-A-610 Class 2/3 quality standards are applied across all boards shipped.

Every rigid flex PCB undergoes 100% electrical testing, impedance testing, solderability testing, AOI (Automated Optical Inspection), flying probe electrical testing, and appearance and dimensional inspection. This rigorous multi-stage testing ensures zero-defect delivery and compliance with IPC Class II quality standards.
