Engineered for demanding applications where reliability meets design flexibility, the PCBSync 4-Layer Rigid-Flex PCB with Hard Gold Finish delivers exceptional performance in a single, integrated board solution. Whether you’re developing wearables, aerospace components, medical devices, or compact consumer electronics, this board is built to perform where standard rigid PCBs simply can’t.
Superior Construction, Layer by Layer
With four precision-engineered layers, this rigid-flex PCB combines the structural integrity of rigid sections with the dynamic bendability of flexible zones — all within one unified design. This eliminates the need for multiple connectors and separate boards, reducing potential failure points and saving critical space in your assembly.
Hard Gold Finish for Maximum Durability
The hard gold surface finish (electroplated gold over nickel) provides outstanding wear resistance, making it the ideal choice for edge connectors, contact pads, and high-cycle applications. Expect low contact resistance, excellent solderability, and a long operational lifespan — even under repeated mechanical stress.
