Lightweight Flexible Printed Circuit Board Heat Dissipation Design

Flex PCB Board, ISO9001,IATF16949 Approved Shenzhen Factory

A Flex PCB or FPCB is a patterned arrangement of printed circuitry and components that utilizes flexible based material with or without flexible coverlay.

Flexible circuits (also called as flex circuits, flexible printed circuit boards, flex PCB, etc) are consisted of a thin insulating polymer film having conductive circuit patterns affixed thereto and typically supplied with a thin polymer coating to protect the conductor circuits. The technology has been used for interconnecting electronic devices since long long time ago. It is now one of the most important interconnection technologies in use for the manufacture of many advanced electronic products.

In practice there are many different kinds of flexible circuits, including one metal layer, double sided, multilayer and rigid flex circuits. The circuits can be formed by etching metal foil cladding (normally of copper) from polymer bases, plating metal or printing of conductive inks among other processes.

Advantage:
1) Accuracy of designs. Most of the advanced electronic devices in use today use flexible circuit boards because of the high level of precision expected of them.

2) They are lightweight. The circuit boards can be folded easily, thus they can be positioned in compartments.

3) Long-term performance. The superior qualities of flexible circuit boards allow them to have durability and long-term performance. The characteristics of low ductility and mass contained in these boards allow them to overcome the influence of vibrations, therefore giving them the capacity to have improved performance.

4) Heat dissipation. Because of the compact designs of the circuit board, there are shorter thermal paths generated and the dissipation of heat is faster compared to other kind of PCBs.

5) Flexibility. Due to their ability to be flexible, it is easily to bend flexible circuit boards to various levels when installing them, thus make it possible to enhance the functionality levels of various electronics.
