What are the benefits of using flexible circuits? Flexible circuits provide below major benefits over rigid circuit boards.

1>. A solution to a package problem;
2>. Reduce assembly costs
3>. Replacement for a circuit board and wires;
4>. Reduce weight and space;
5>. Dynamic Flexing;
6>. Thermal management/high temperature applications;
7>. Aesthetics.

So most designers choice the flexible circuits for most applications.
