What is Altium Rigid Flex Design?
Altium rigid-Flex Printed circuit boards (PCBs) combine the benefits of rigid and flexible boards. It is a set of tools to create a unified design that combines rigid PCB boards and flexible circuits into one system. It enables the designer to define the board stack-up, circuitry, and layer structure for a rigid-flex board. Altium Rigid Flex Design provides an intuitive and efficient workflow from schematic capture to layout and fabrication.
Materials for Altium Rigid-Flex Designs

The following are the materials you should choose for excellent Altium rigid-flex solutions:
- Substrate Films: Substrate films are rigid-flex systems’ structural support and electrical insulation base. Engineers must carefully select these films to fulfill the application’s performance and dependability criteria. Polyimide (PI), polyamide-imide (PAI), polyester (PET), and polyethylene terephthalate (PET) are frequent choices for rigid-flex substrate materials (PETG). These materials have superior dielectric and mechanical properties, making them appropriate for high-performance applications.
- Conductors are the electrical routes that connect components and allow signals to flow through the rigid-flex construction. Copper and silver are the most famous conductors utilized in rigid-flex systems. Copper is less expensive and the material of choice for most uses. Silver is more costly than copper, but its superior electrical characteristics make it excellent for high-speed and high-density systems.
- Coverlay Films: Coverlay films help insulate and safeguard the copper traces on rigid-flex designs. Polyimide (PI), polyamide-imide (PAI), and polyethylene terephthalate (PET) are widespread coverlay materials (PET). These materials’ exceptional dielectric characteristics and mechanical flexibility make them ideal for high-performance applications.
- Adhesives: Adhesives help adhere substrate films to component layers and other rigid-flex constructions. Epoxy, acrylic, and polyurethane are common alternatives for rigid-flex bonds. These materials offer superior stickiness and flexibility, enabling a secure connection between the layers.
