PCB Types – Flexible vs Rigid vs Rigid-Flex PCB

A printed circuit board (PCB) is a multi-layered electrical circuit that connects electronic components through the use of conductive tracks etched into one or more layers of copper foil on a non-conductive substrate material. PCBs are smaller, lighter, and more efficient than their traditional wired counterparts, which makes them ideal for use in increasingly complex and miniaturized technology. They are also easier to manufacture, install, and maintain, for more cost-effective and reliable operation.

PCB manufacturing is largely automated, which makes it extremely efficient for manufacturing even highly complex boards with extreme precision. Although all PCBs operate under similar principles and contain similar components, each type of PCB has unique benefits for specific applications.

Choosing the Best PCB for Your Application

PCBs are available in a wide variety of designs, the most common of which are flexible, rigid, and rigid-flex. These PCB designs are categorized based on the fundamental stiffness of the PCB substrate, and each offers distinct advantages for particular applications.

. Flexible PCB

Flexible PCBs are characterized by their ability to bend, fold, and crease in order to fit into small or irregularly shaped voids. Rather than manufacturing the product to fit the PCB, a flex PCB can be made to fit within the design. Flexible PCB board materials also tend to be lighter, stronger, and more heat-resistant than rigid PCB materials.

. Rigid PCB

Rigid PCBs are characterized by the unyielding nature of their substrate material. While they can be less expensive to fabricate than flexible PCBs, rigid PCBs do not have the same level of versatility. Rigid PCBs exhibit a high degree of durability and strength, which makes them ideal for applications in harsh or extreme conditions, where space is not a concern.

. Rigid-Flex PCB

Rigid-Flex PCBs are multi-layered circuit boards that combine the stability of rigid circuit board designs with a more flexible substrate material. This allows manufacturers a greater level of control over product design while ensuring durable circuit connections. The flexible substrate allows rigid-flex PCBs to fit into unusual geometries and tight spaces common in automotive, aerospace, and medical equipment.
