Flexible PCB boards have multiple advantages, whether you plan to use them in future projects or modify existing designs. Here we detail some of the most influential advantages of flexible PCBs, including packaging, reliability, functionality and cost savings.

Unlike rigid printed circuit boards, flexible circuit boards can be used where other solutions are not feasible. By replacing wired components with flexible PCB boards, more space can be saved. When using wired solutions, flexible PCB designs usually only require about 10% of space and weight. Flexibility also provides stronger bending capabilities. Because of its ability to take up space more efficiently, there is even an opportunity to replace multiple circuit boards, connectors, etc. with a single rigid-flex unit.

Reliability of flexible printed circuit

When it comes to reliability, flexible and rigid-flex printed circuit boards have covered you. Flexibility can reduce the total number of interconnections required, which means fewer solder joints, connectors and contact crimps. By reducing interconnections, potential sources of failure will be reduced, thereby increasing reliability. In addition, the weight reduction and flexibility of the circuit can improve vibration and shock performance.

Flexible PCB function

Flexible material properties perform very well in high-speed controlled impedance design. As far as component/connector components are concerned, the flexible circuit can accept any component or connector that can be assembled on a rigid PCB. Other options include ZIF connectors, crimp contacts and direct soldering.

Flexible PCB boards also perform well in harsh environments. Extreme temperature applications can run up to 200°+Celsius, and flexibility provides better heat dissipation than rigid printed circuit boards. Flexible circuit boards also have excellent resistance to chemicals, radiation and ultraviolet rays.

Cost saving benefits

In addition to performance advantages, considering the savings advantages alone makes flexible circuit boards worth the investment. The use of flexible printed circuit boards reduces the overall finished product assembly packaging and material requirements, thereby reducing costs. Due to fewer parts and simplified installation, replacing multiple components reduces assembly costs. The increased reliability of flexible printed circuit boards creates durable products, again saving you from having to spend more time reordering.
