Prototype Assembly

Our prototype runs are often a mix of large BGAs and tiny 0201 components, and we’ve had issues with other assembers on yield. PCBsync’s assembly team delivered a perfect first-run success. The board was pristine, the solder joints were impeccable under the microscope, and everything worked straight out of the box. Their attention to detail in the assembly process saved us weeks of debug time. They are now our go-to for critical prototype assembly.

Electronic Manufacturing

Scaling from hundreds to tens of thousands of units for our smart home device presented huge supply chain and manufacturing challenges. PCBsync’s full electronic manufacturing service was the solution. They didn’t just build the PCB; they managed the entire box-build, sourced all components (even during shortages), and implemented a rigorous quality control system that drastically reduced our field failure rate. They act as a true extension of our own production team.

PCBSync Ultra-Thin Rigid-Flex PCB (0.4 mm) with ENIG

Product Details

Full Product Description:

Introducing the PCBSync Ultra-Thin Rigid-Flex PCB (0.4 mm) with ENIG — the industry-grade solution engineered for designers and manufacturers who demand precision, reliability, and superior performance in compact electronic assemblies.

What Is a Rigid-Flex PCB? A rigid-flex PCB combines the structural stability of rigid boards with the adaptability of flexible circuits. This hybrid design eliminates bulky connectors and ribbon cables, reducing assembly complexity while improving signal integrity across your entire system.

Why Choose PCBSync Ultra-Thin at 0.4 mm? At just 0.4 mm total thickness, this board is purpose-built for space-constrained applications including wearables, medical devices, aerospace electronics, smartphones, and IoT modules. The ultra-thin profile enables tight bend radii without compromising mechanical strength or electrical performance.

ENIG (Electroless Nickel Immersion Gold) Surface Finish The ENIG surface finish delivers a flat, oxidation-resistant, and RoHS-compliant solderable surface — ideal for fine-pitch SMD components and BGA pads. ENIG ensures excellent solderability, long shelf life, and consistent performance in high-reliability environments.

Key Features:

Total thickness: 0.4 mm ultra-thin profile
Surface finish: ENIG (Electroless Nickel Immersion Gold)
Design: Rigid-flex hybrid construction
Compliance: RoHS & IPC Class II/III compatible
Applications: Wearables, medical, aerospace, consumer electronics

PCBSync Quality You Can Trust Every PCBSync rigid-flex PCB undergoes rigorous electrical testing, impedance control verification, and AOI inspection — ensuring zero-defect delivery for your critical projects.
