Engineered for engineers who refuse to compromise, the PCBSync Impedance-Controlled Rigid-Flex PCB combines the structural strength of rigid boards with the dynamic flexibility of flex circuits — all backed by a premium Electroless Nickel Immersion Gold (ENIG) surface finish.

Precision Impedance Control for Reliable Signal Integrity

Designed to meet the demands of high-speed, high-frequency applications, our rigid-flex PCBs are manufactured with tight impedance tolerances (±5% or better). Whether you’re routing RF signals, high-speed data lines, or differential pairs, PCBSync ensures consistent electrical performance across every trace — eliminating signal loss, crosstalk, and reflections that can compromise your design.

ENIG Surface Finish — Superior Solderability & Longevity

The ENIG coating provides a flat, oxidation-resistant surface that delivers excellent solderability for fine-pitch SMD components and BGA packages. With a nickel barrier layer and immersion gold top coat, your PCB resists corrosion and maintains long-term reliability even in harsh operating environments.
