Advantages of Multilayer Flexible Circuits
Multilayer flex circuits boards are manufactured by combining single-sided and/or double-sided circuits. Then, these combined circuits are interconnected through plated through holes. With this technology, high-density interconnection can be easily achieved. These interconnections are very important for applications where one or more layers of conductors cannot meet circuit packaging requirements or pin addresses.
There are many benefits of using multilayer flex circuits boards, and because of their design requirements, they are the first choice in most industries.
1. Multilayer flex circuits board reduces assembly cost and time
When designing and manufacturing multilayer flex circuits, relatively little manual labor is required. In turn, this reduces the chance of production errors. Multilayer flex circuits boards eliminate the need for expensive bonding wires, packaging and wiring.
There is no need to replace or install a discrete hard PCB, but to replace or install the entire interconnection system. This helps minimize wiring errors, thereby reducing manufacturing costs.
2. Multilayer flex circuits board reduces packaging size and weight
Unlike rigid boards, multilayer flexible PCBs are light in weight and take up less space. These flexible boards have the thinnest dielectric substrates and can provide a more simplified design.
3. Multilayer flex circuits boards can increase heat dissipation
Multilayer flex circuits board has a larger surface-to-volume ratio, allowing a shorter thermal path. In addition, the multilayer flex circuit has a slim design, which helps increase heat dissipation on both sides of the circuit.
4. Multilayer flex circuits boards can improve durability
In designs with moving parts, a flexible circuit is the best choice because it can be bent up to 500 million times. Polyimide is the most commonly used material in flexible circuit boards and has excellent thermal stability.
Therefore, the multilayer flex circuits board can easily withstand high temperatures. Moreover, due to the excellent thermal stability of polyimide, it provides a better quality substrate for surface mounting compared to rigid boards.
5. Multilayer flex circuits boards improve system reliability
The biggest failure of the circuit occurs at the interconnection point. Multilayer flex circuits boards meet the interconnection needs. This helps to improve the reliability of the circuit.
6. Multilayer flex circuits boards can be used for high-density applications
Multilayer flex circuits boards have very thin wires, leaving enough space for other components. The multilayer flex circuits board has a high board density.
