Flexible PCB - Simple & Fast for Creating Interconnects

Overview of Flexible PCBs

Flexible PCBs (also known as FPCs) use thin, flexible dielectric materials between layers of copper with a minimum thickness of only 50μm. Using these materials allows for the circuit to fold, flex, and twist as well as overall reducing the size and weights of electronic designs.
FPCs are typically 75% lighter than a similarly sized rigid PCB! All of these facts make flexible PCBs extremely common and widely used today. PCBONLINE is able to provide you with the best flexible PCBs that are available.

Manufacturing Terms

If you need to utilize FPC designs for your application, then you should first familiarize yourself with the common terminology that is used. A few common terms for the flexible PCB industry are found below:

1. FPC Flexural failures

FPC materials can be damaged or broken due to repeated or excess bending and flexing actions of the substrate. This type of failure is called a 'flexural failure.'
2. Polyurethane soft materials

A polyurethane soft materials are normally attached with a rolled copper foil or electroplated copper for use in a PCB construction. This type of material is often the base material used in a flexible PCB.
