FCB, FCPB are acronyms for Flexible Printed Circuit Boards. FCB's gained special attention because they solved the high density, electronically stabile, flexible, extremely thin, high thermal transfer and exceptional heat resistance that is necessary for the production of tight packaging.

Products manufactured using FCB's allows the miniaturization, durability and weight to still provide the 3D adaptability for multichip modules. Flexible circuits have allowed some of the once impossible products and machines to become reality. With the ability to build specialized flex circuits that merge mechanical motion with electronic connectivity.


The materials used to manufacture FCB's are what give it the ability to achieve extremely thin, dense and fatigue resistant results. Flexible circuit materials are halogen-free and by using these materials, flexible circuits are able to tolerate higher temperatures. FCB's also have extremely low moisture absorption.

The materials used allow manufacturers to laser drill, punch, or chemically mill very small holes which gives room for more dynamic engineering possibilities. Products used to make FCB's include base films, conductor, finishes, masks, bondply, coverlays, conductors, adhesives and backers.

Flexible circuits represent many of the products we use today. They allow a simpler and more reliable solution then conventional pcb's. When it calls for tight packaging and coupled with maneuverability, you need a flexible circuits. Flexible circuits have allowed the products of tomorrow become a reality today. Below we have assembled general information on the materials and construction of an FCB.
