Double Layer Flex PCB Board
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.
