Why rigid-flex

One board that folds into your product

A rigid-flex PCB merges rigid and flexible circuits into a single, connector-free part — saving space and weight, enabling 3D folding into tight enclosures, and improving reliability where shock, vibration and repeated movement would stress a cable or connector.

Beyond the basics

Advanced & high-end rigid-flex processes

Constructions for tight folds, high layer counts and the most demanding reliability requirements.

Multilayer rigid-flex

Multiple rigid sub-stacks linked by one or more flex layers, integrating a whole system into a single folding board.

2–32 layers

Book-binding & air-gap

Loose-leaf / book-binding and unbonded (air-gap) flex layers for a smaller bend radius and longer flex life.

Tight folds

HDI in rigid sections

Laser microvias, stacked/staggered vias and fine lines in the rigid areas for dense component fan-out.

Microvia

Controlled impedance

Impedance control maintained across the rigid-to-flex transition, with stackup design and TDR verification.

To ±7%

EMI shielding film

Conductive shielding film over flex areas for noise-sensitive, high-frequency and medical designs.

Shielded flex

Stiffeners & ZIF

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

Rigid-flex PCB capability — FAQ

Rigid-flex boards are built from 2 to 32 layers, combining rigid FR-4 sections with flexible polyimide sections (typically 1 to 12 flex layers), including multilayer and HDI constructions.

A rigid-flex PCB integrates rigid board sections and flexible circuit sections into a single part. It removes connectors and cables between boards, saves space and weight, lets the assembly fold into 3D enclosures, and improves reliability in environments with shock and vibration.

Rigid sections use FR-4 (high-Tg available); flexible sections use polyimide (PI / Kapton), PET or PEN with polyimide coverlay. Stiffeners are available in FR4, aluminum, polyimide and stainless steel, and EMI shielding film can be added.

Built and inspected to IPC-6013 and IPC-2223 for the flex / rigid-flex construction, and IPC-6012 for the rigid sections, with IPC-A-600 and IPC-A-610, under an ISO 9001 system. They can be produced UL, RoHS and REACH compliant, with ISO 13485, IATF 16949 and AS9100 support.
