An FPC line board is a core component in modern flexible electronics, enabling compact design, high-speed signal transmission, and superior mechanical reliability. This in-depth guide explains what an FPC line board is, how it works, its manufacturing process, applications, and why companies like Akeson are driving innovation in this field. The article is designed to help engineers, buyers, and decision-makers fully understand how FPC line boards enhance flexible PCB performance.
An FPC line board (Flexible Printed Circuit Line Board) is a type of flexible circuit board designed to support complex electrical interconnections on thin, bendable substrates. Unlike rigid PCBs, FPC line boards are engineered to flex, fold, and twist while maintaining stable electrical performance.
The term “line board” refers to the precision copper traces (lines) that form the conductive paths. These lines are optimized for high-density layouts, fine pitch spacing, and high-frequency signal integrity.

| Layer | Material | Function |
|---|---|---|
| Top Coverlay | Polyimide | Protection & insulation |
| Copper Traces | RA Copper | Signal transmission |
| Base Film | Polyimide | Flexibility & mechanical support |
Precision line width control and smooth copper surfaces reduce impedance mismatch and signal loss, making FPC line boards ideal for high-speed and RF applications.
FPC line boards allow for compact product design, reducing connectors and wiring harnesses. This results in lighter, thinner, and more reliable electronic assemblies.
Advanced manufacturers like Akeson integrate automated optical inspection (AOI) and impedance testing to ensure consistent quality.
