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.
