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 Polyimide-Based Rigid-Flex PCB with ENIG

Product Details

Upgrade your electronics design with the PCBSync Polyimide-Based Rigid-Flex PCB with ENIG (Electroless Nickel Immersion Gold) — a premium circuit board solution that combines the structural strength of rigid PCBs with the dynamic bendability of flexible circuits.

Why Choose a Polyimide Rigid-Flex PCB?

Polyimide (PI) substrate is the industry standard for high-performance flex circuits, offering superior thermal stability (up to 260°C), excellent dielectric properties, and outstanding chemical resistance. This makes the PCBSync rigid-flex PCB ideal for applications where conventional FR4 boards simply can’t deliver.

ENIG Surface Finish — The Gold Standard

The Electroless Nickel Immersion Gold (ENIG) finish provides a flat, oxidation-resistant surface that ensures reliable solderability, long shelf life, and consistent electrical contact. ENIG is especially critical for fine-pitch components, BGA packages, and high-frequency signal integrity requirements.

Key Features & Specifications:

Polyimide dielectric base for thermal and chemical durability
ENIG surface finish for superior solderability and corrosion resistance
Combined rigid and flexible zones reduce connectors and assembly points
Available in custom layer counts, stack-ups, and impedance-controlled configurations
IPC Class 2 and Class 3 compliant manufacturing
RoHS-compliant materials

Applications: Medical wearables, aerospace electronics, robotics, foldable displays, automotive sensors, and compact IoT devices.
