Types of Flexible Circuit Boards: Common Properties and Unique Features

Flexible circuit boards, also known as flex PCBs, find extensive use across a wide range of applications. They are particularly valuable for products that require flexibility and durability. Flex PCBs are also suitable for applications with specific temperature requirements or high precision. The choice of flex PCB type depends on factors such as the intended application and the desired specifications of the final product.
There are two main types of flex PCBs: rigid-flex and semi-rigid rigid flex (SRF). Rigid-flex PCBs are similar to standard rigid printed circuit boards but with additional layers to achieve a thinner profile. This allows them to bend without easily breaking when subjected to mechanical forces or impact shocks over time. Moreover, they can return to their original shape even after being bent, making them ideal for various applications that demand shock resistance, avoiding potential damage to other materials like glass.
Flex Rigid PCB: Combining Rigid and Flexible Boards
A flexible PCB, also known as a flex PCB, is a type of printed circuit board or substrate that integrates both rigid and flexible components. It is constructed by permanently connecting rigid and flexible boards together. The primary objective of a flex PCB is to provide design flexibility, enabling it to withstand mechanical stress and environmental factors like temperature fluctuations, shock, vibration, and more.
Flexible PCBs have many applications including:
- Wireless devices like cell phones, tablets, sensors etc…
- Medical devices such as pacemakers, stents etc…
- Automotive Industry (Cars) – Airbag modules
