Beyond the basics

Advanced & high-end flex processes

From simple single-layer flex to complex rigid-flex assemblies that bend, shield and survive millions of cycles.

Rigid-flex integration

Rigid sections and flexible tails in one board — eliminating connectors, saving space and boosting reliability.

2–32 layers

Multilayer & HDI flex

Multilayer flex with laser microvias and fine lines for dense, high-pin-count flexible interconnects.

Microvia

Dynamic flexing

Bend-to-install or continuous-flex designs engineered with rolled-annealed copper and optimized bend radius.

Millions of cycles

EMI shielding film

Conductive shielding film over flex circuits for noise-sensitive and high-frequency applications.

Shielded flex

Stiffeners & ZIF contacts

Selective stiffeners and bevelled gold ZIF / contact fingers for connector insertion and component areas.

FR4 · PI · steel

Controlled impedance

Impedance-controlled flex and rigid-flex with stackup design support and TDR verification.

Microstrip / stripline

Flex PCB capability — FAQ

Flexible circuits are built from 1 to 12 layers, and rigid-flex boards from 2 to 32 layers, including multilayer and HDI flex constructions.

Base films include polyimide (PI / DuPont Kapton), PET and PEN, plus FR-4 for rigid-flex transitions. Stiffeners are available in FR4, aluminum, polyimide and stainless steel, and we can add EMI shielding film.

Down to 4 mil line width and space on 0.5 oz copper (5/5 mil on 1 oz), a minimum hole of 8 mil, and copper weights from 1/3 oz to 2 oz.

Built and inspected to IPC-6013 and IPC-2223 (with IPC-A-600 and IPC-A-610) under an ISO 9001 system, and produced UL, RoHS and REACH compliant, with ISO 13485, IATF 16949 and AS9100 support.
