Key Product Highlights

True Rigid-Flex Construction

Seamlessly integrates rigid FR4 IT180 sections with flexible polyimide layers in a single,unified board.

Enables 3D assembly,reduces connectors,and enhances reliability in dynamic or compact designs.

Heavy-Copper Inner Layers for Power&Thermal Performance

Copper stack-up:1/H/H/1 oz—features heavy inner layers(H) for enhanced current carrying capacity and superior thermal management.

Ideal for power circuits,motor controls,and LED systems requiring robust thermal and electrical performance.

Slim & Durable Profile

Finished thickness:1.2mm—optimized for lightweight and space-constrained designs without sacrificing mechanical strength.

Min.hole size: 0.2mm and min.trace/space: 7.8/6 mil—supports reliable interconnection and fine circuit routing in both rigid and flexible zones.

Enhanced Surface Finish for Long-Term Reliability

Immersion Gold(ENIG)with Au>2µ″—provides a thicker gold layer for excellent corrosion resistance,wire bonding compatibility,and reliable solder joints,even in flexing areas.

Why Choose This Rigid-Flex PCB?

Reduces assembly size and weight by eliminating board-to-board connectors and cables.

Improves durability in applications with motion,vibration,or repeated bending.

High-performance IT180 material ensures stable electrical properties for signal integrity in high-speed or controlled impedance environments.
