This section introduces how to choose flexible printed circuit boards (FPCs) for medical devices and highlights recommended types.
If you're involved in medical device development, this information will be a good hint.
When selecting a flexible PCB (FPC) for use in medical equipment, the most important considerations are precision and reliability.
Even minor circuit defects or noise can lead to device malfunctions and pose risks to diagnostic accuracy. In some cases, these issues may directly affect patient safety. For this reason, the precision and reliability of the FPC are crucial.
There are many types of flexible PCBs, but two that meet these high standards are multilayer flexible PCBs and rigid-flex PCBs. Both offer excellent precision and reliability, making them ideal for integration into medical devices.
Multilayer flexible PCBs allow for high-density wiring on a single board, eliminating the need to arrange multiple separate boards. This integration also removes the need for connectors between boards. This integration also removes the need for connectors between boards.
Rigid-flex PCBs combine the features of both rigid and flexible circuit boards. They enable multiple boards to be combined into one, achieving a connector-free configuration.With added flexibility, they are also well-suited for complex, three-dimensional assemblies.
Multilayer and rigid-flex PCBs are ideal for medical devices because they help reduce electrical noise. Even minor noise can pose risks to device performance, and in the medical field—where precision and reliability are non-negotiable—there’s no room for error.
By consolidating circuits into a single board, these PCB types eliminate the need for connectors, which are a common source of noise. This not only improves performance but also contributes to device miniaturization, while maintaining the high standards required in medical applications.

Handling Flexible PCBs
Medical devices come in many forms, but nearly all require a high degree of accuracy and dependable performance. When selecting an FPC, prioritize options that offer both precision and reliability to meet the demands of medical use.
Choosing a manufacturer that can support everything from design to production can significantly reduce both cost and time. Below are three trusted FPC manufacturers from Japan, each with unique strengths in their respective fields.
