Upgrade your electronic designs with the PCBSync 4-Layer Rigid-Flex PCB with Immersion Silver — a high-performance circuit board solution engineered for applications that demand flexibility, reliability, and superior electrical conductivity.
What Is a 4-Layer Rigid-Flex PCB?
A 4-layer rigid-flex PCB combines rigid and flexible substrates into a single, integrated circuit board. This hybrid design eliminates the need for connectors and cables between board sections, reducing assembly complexity, minimizing signal loss, and saving valuable space in compact devices. PCBSync’s 4-layer stackup provides exceptional signal integrity for high-speed, high-density applications.
Why Choose Immersion Silver Finish?
The Immersion Silver (ImAg) surface finish delivers a flat, solderable surface with outstanding electrical performance. Compared to HASL and OSP alternatives, immersion silver offers excellent co-planarity, fine-pitch solderability, and strong oxidation resistance. It is RoHS-compliant and lead-free, making it the ideal choice for medical devices, aerospace systems, consumer electronics, and IoT hardware.
